Back to Latest News page TO THE BEEKEEPERS OF NEW ZEALAND This accompanying report from the Executive, in support of eradication, has come about because MAF Biosecurity Authority had commissioned AgriQuality to furnish a report on the Control of Varroa. This was presented to the Finance Committee of Government on Tuesday, 20th June. The report produced by AgriQuality had very little input from the beekeeping industry, even though two members were belatedly included. (They were told that beekeepers' input was not required by AgriQuality for them to write the document). MAF Biosecurity Authority is placing more emphasis on the Control of Varroa option rather than on the Eradication option. On 20th June, the NBA Executive convened a group of Commercial Beekeepers to consider the eradication option. They produced this report, which the Executive would like you to consider. The Executive must have the report about the Eradication option into the Ministers' offices by Wednesday, 28th June. Because of the time pressure we would like you to discuss this with your branch members and take a vote on these options; "Control" or "Eradication". One person, one vote. Please also record how many people have hives in the Infected, Buffer and Surveillance zones. If unable to attend the meeting, please ring, fax or E-mail your Branch Secretary or President and cast your vote. The members of this working committee are:

MISSION STATEMENT
The listed contributors consider that the long term effect of this Plan is to return New Zealand beekeeping to its varroa mite free status, thereby enabling continuation of profitable production of honey, beeswax, live bees, bee products and long term pollination, both paid and unpaid, of New Zealand horticultural and agricultural crops, to the benefit of all New Zealand citizens.
1. INTRODUCTIONThis document has been prepared by the National Beekeepers Association, as an alternative to the Eradication document prepared by AgriQuality New Zealand. The participants who have prepared this document, are expert commercial beekeepers (apiarists) who have diverse skills in all facets of Apiculture and business management. They are dedicated to beekeeping and earn their income from their beekeeping operations. The Executive believes that the documents prepared by AgriQuality reflect the non-commercial beekeeping acumen of the contributors, so we have proceeded to formulate the following document, which we believe will have greater beekeeper support. We have taken the liberty of using various sections from within the AgriQuality document, where we have deemed them to be appropriate. 2. EXECUTIVE SUMMARY2.1To ensure that the detrimental effect of Varroa destructor on New Zealand's economy is kept to a minimum in the medium to long term.2.2To eradicate varroa mites from New Zealand as soon as possible (starting immediately).2.3To ensure that the South Island remains free from varroa while eradication of the mites takes place in the North Island.2.4Commercial beekeepers' knowledge and business management acumen is required for the eradication of varroa mite. This must be recognised by MAF and MAF must continually allow beekeepers input into designing and controlling of the eradication programme. A successful eradication programme will only be achieved with equal partnership between the Beekeeping Industry and MAF.2.5Hive movements or bee movements not to be allowed in the Buffer zones for the seven months from the 1st January to the 1st August 2001. However, movement of Hives may be allowed under exceptional circumstances under strict permit controls. This will greatly improve the chance of eradicating varroa mites.2.6Compensation must be adequate to beekeepers. $125 per hive with $25 cleaning and storage costs should meet this requirement, also other compensation as listed.2.7This eradication programme will maximise the chance that the essential requirements of kiwifruit growers, other orchardists, seed growers and farmers will receive hives for pollination.3. RECOMMENDATIONSAll hives to be given a unique New Zealand number to aid in the tracing of hive movements. All hive and bee movements in the buffer zones to be halted from the 1st January to 1st August 2001 - detection and destruction of mites easier without hive movement. We should set up a varroa eradication organisation, managed by the Beekeeping Industry and MAF Biosecurity in equal partnership. Beekeepers and AgriQuality to be the preferred contractors. Bait stations will work if the correct dimensions solutions and poisons are used. Additional methods should be used at the same time to assist speedy eradication of all ferals. Trees to be sprayed preferably while flowering, with sugar solutions toxic to bees. E.g. spray willows or other flowering shelter belts surrounding kiwifruit orchards, with sugar solutions toxic to bees. This spray must have NO environmental detrimental effect. Information on double testing for varroa mite confirms accuracy of surveillance methods used. This information must be released to increase beekeeper and government confidence in the eradication programme. To give extra beekeeper and government confidence in the location of varroa mites, repeat testing should be carried out for varroa mites immediately during the next week, testing additional apiaries for the second time. Immediately carry out further surveillance along main highways between known varroa infested areas to areas where bees are regularly transported - e.g. kiwifruit orchards. Testing in other areas throughout NZ should have emphasis on testing apiary sites in close proximity to main arterial routes used regularly by beekeepers transporting live bees. The above test results will all give increased assurance to beekeepers and government alike, of varroa mite location.
4. INDUSTRY CONCERNS4.1Declaration of InvolvementAgriQuality New Zealand, who has a vested interest in each of these options, has written both the Eradication document and the Control document. It is the Industry's concern that they have never made a declaration of involvement, in that they are likely to gain employment from these options.4.2 Cost of Varroa to CountryIf varroa cannot be eradicated, the long term cost to our Industry and New Zealand will be billions of dollars. The beekeeping industry has already invested millions of dollars into this Biosecurity exercise. In supporting the exercise beekeepers have received no payment for assisting in the delimiting survey. Action is now required for a large cash injection, no matter what the decision of Government is on eradication of varroa.4.3 Clover WeevilWill affect the cost that varroa mite will have on pastoral farming and where you have clover weevil in the pasture, it is more important than ever to have good pollination of the remaining flowers, by bees.4.4 Varroa SpreadHow fast is varroa going to spread in New Zealand, particularly when you take into account the genetic diversity of bees in New Zealand which has had no legal introduction of live bees for over 50 years?4.5 IncursionWhen we have another incursion of our Border and another exotic bee disease arrives in New Zealand it will be absolutely devastating to New Zealand's economy if we have not eradicated varroa.4.6 Hive DeathsMany hives will die from varroa, even if treated immediately with Apistan strips, because of advanced varroa infection.4.7 Affect on EconomyLiving with varroa will be very expensive for New Zealand's economy when varroa becomes miticide resistant (Mike Block's letter encl.).5. CRITICAL ASSUMPTIONSThe following critical assumptions were used in the development of this Operational Plan: Feeding Habits and Eradication of Feral Bees All feral hives have bees that bring nectar into the hive from flowers, for the survival of the hive. Beehives can be killed out by naturally poisonous nectar sources (Karaka trees - Trevor Palmer Jones). Beehives are killed out by poisonous sprays being applied to flowering plants in New Zealand (1942, arsenic sprays in Hawkes Bay). Bees collect poisonous nectar from flowers sprayed with toxic sprays and bees in the hive are killed by this nectar (e.g. carbaryl in Hawkes Bay orchards and toxic sprays kiwifruit orchards). Bees in all feral colonies are the direct descendants of New Zealand farmed bees. Farmed beehives generate a high proportion of feral colonies on a yearly basis. The bees from all beehives will readily search out and consume honey and sugar solutions, with the correct moisture content, in close proximity to their hives. Certain aromas attract bees Bees will collect sugar solutions sprayed onto the leaves and flowers of plants. Bees in Canada that are regularly fed sugar at a short distance from the beehive all collect sugar. Beekeepers in New Zealand have fed granulated honey to beehives in the open. All farmed beehives in close proximity fed from this honey source. Any eradication programme for ferals using poison bait stations will have enough area covered with sugar, honey and poison solution, to allow all feral hives access to feed at one time. Small bait stations will be dominated by local strong hives. 5.1 Baiting BeesBees will fly at least 500m from their colony to collect a honey bait (test being carried out currently to confirm this).5.2 Bee FlightThe maximum distance bees are likely to fly under normal foraging conditions is 7km. Drone drift is likely to occur between hives within an apiary and between localised apiaries.5.3 Blip OperationsMany will occur and have to be dealt with but this paper makes no prediction as to when the blips will occur. Estimation is based on the current number of blips detected in the delimiting survey (5), an analysis of site sensitivity analysis (72%), and the effectiveness of tracing (75-95%).5.4 DepopulationDepopulation of registered hives will be concluded before any significant pollination will be required in spring 2000.5.4.1 Depopulation CompensationStrictly on a per colony basis, not taking into consideration of the size of hives, amount of stored honey on hives, or the condition of equipment. No compensation will be paid on colonies found to already be dead at the time of depopulation, unless based on the judgement of an Authorised Person the hive has died as result of a varroa infestation.5.5 EnforcementMAF will prosecute beekeepers who are found to have breached movement control or registration requirements.5.6 Eradication PeriodAuckland Eradication zone - Eradication Zone to be kept free until Winter 2001, after which time managed hives can be reintroduced.5.7 Feral ColoniesFeral colonies can be depopulated (killed) using bait stations.5.8 Compliance with Movement ControlBeekeepers and others can be stopped from moving bees outside the Eradication Zone.5.9 Natural Mite SpreadThe spread of varroa between hives and between apiaries under natural conditions (no human assistance) is a product of the drift of bees between hives, the robbing of weak hives by other hives, and the absconding of bees in a heavily infested hive (resulting in the movement of the absconding bees into either a vacant hive or a hive already populated by a colony of bees). The natural spread of varroa is not likely to be greater than 5km per annum.5.10 Risk of ReinfestationThe risk of reinfestation following depopulation is the same or less in the Eradication Zones as in the Buffer Zones. The risk of infestation is less in the Surveillance Zone than in the Buffer Zone.5.11 Surveillance Outside Eradication and Buffer ZonesLevel of testing designed to detect any infection if it is present at a greater than 0.2% prevalence (required to achieve OIE acceptance of disease-free status).5.11.1 Surveillance in Eradication ZoneAll hives in all apiaries, same throughout all 4 years.5.11.2 Surveillance in Buffer ZoneAll hives in all apiaries in year 1, 50% of apiaries in years 2 to 4.5.11.3 Buffer ZoneThe Buffer Zone is set using a geographic separation between the upper and lower North Island. There is little movement of beehives between these two geographic areas. The Buffer Zone is the area on the north side of this geographic separation (i.e., the northern North Island).5.11.4 Infected Zone15km radius around any apiary infected with varroa in the South Island, 15km with heavily infested hives in the North Island, 7.5 km with low infestations.5.11.5 Surveillance ZoneThe Surveillance Zone is set using a geographic separation between the upper and lower North Island. There is little movement of beehives between these two geographic areas.5.12 EnforcementThe enforcement of New Zealand law will be actively supported by the National Beekeepers Association, and Ministry of Agriculture and Forestry.5.13 Sensitivity of TestThe Apistan test is considered to be highly sensitive (>83%) on a hive basis for heavy infections, and for light infections (1 varroa mite) that occurred more than one year ago. Hive level sensitivity is likely to be 50% for light infections that occurred approximately six months ago, and poor for light infections occurring within six months of testing.5.14 Apiary site level sensitivityIs estimated to be 72% for infections occurring more than six months ago. Testing every hive within an apiary, is expected to yield site level sensitivities of 89% for apiaries infected one year ago, and 76% for apiaries infected six months ago.5.15 Testing all hivesTesting all hives on all sites is likely to detect 90% of infected beekeepers and 99% of clusters, assuming a site level sensitivity of 89%, an intra cluster site prevalence of 37% and an intra beekeeping operation prevalence proportional to the number of sites owned by the beekeeper.5.16 Movement Control, North Island to South IslandThe movement of bees and other risk goods from the North to the South Island will be prohibited for as long as the South Island remains free of Varroa or while any attempt is being made to eradicate an incursion.5.17 South Island IncursionsThe plan assumes blips will take place, but this paper makes no prediction as to how many or when the blips will occur. The Eradication Operational Plan also makes a critical assumption that extension programmes will be provided to help lessen the impact of the mite on New Zealand beekeeping, and on the horticultural and agricultural industries that rely on honey bees for pollination.5.18 Extension activitiesInclude an initial training seminar for all interested parties (using an overseas expert), production and distribution of a varroa booklet to all registered beekeepers.5.19 The Operational PlanIncludes various options designed to keep varroa from spreading to the South Island, options are also included for an eradication programme in the event that mites are found there.5.20 A full survey of all apiariesIt is intended to provide a baseline of information regarding mite freedom. The second (Annual Three Tier Surveillance) is designed to provide on-going information, with intensity of surveillance based on level of risk. The three-tier programme includes sentinel apiaries in very high-risk ports of entry, increased surveillance of high-risk apiaries, and normal surveillance of all other apiaries.5.21 The Operational PlanIncludes a proposal for New Zealand-based research activities, since it is acknowledged that overseas control methods are unlikely to be directly applicable because of differences in New Zealand beekeeping practices, climatic and floral conditions, honeybee strains, and the interaction of bee's viruses present in New Zealand with varroa. The goal of the research programme is to produce a sustainable eradication strategy that minimises cost, chemical use, and the development of resistance in mites and residues in the products that are being produced.6. REQUIREMENTS FOR INDUSTRY ACCEPTANCE OF ERADICATIONNo eradication attempt, no matter how technically sound, will succeed without the co-operation of most of the beekeepers. They are the stake-holding group upon whom the effects will fall most heavily and prosecutions should take place on non-compilers. A small group within the beekeeping industry is opposed to eradication. If eradication of varroa from New Zealand is to be successful, it is necessary that those presently opposed are persuaded that the eradication programme to be attempted in New Zealand has significant components, not found in overseas programmes, that will greatly improve the likelihood of success. These components can be listed as:
7. DEPOPULATION OF REGISTERED HIVES7.1 Introduction:Depopulation of the infected areas - Auckland, Hauraki, South Auckland, Te Puke, and the other outlying infected places, should be depopulated in various stages, and consideration should also be given to the severity of the infections, which will determine how far out from the infected apiary (radius), the depopulation will be carried out i.e. low infestation - 7.5km; Medium-High infestation - 15km. 7.2 BackgroundFor the purposes of this Operational Plan, registered hives are those colonies of honeybees managed by man and registered by a beekeeper under government legislation. No record will be kept of the number of boxes of combs per hive, the condition of the equipment or the amount of stored honey present, as it will have no effect on Compensation. Two queen colonies will be treated as one hive. Hives with splits (i.e.. two colonies separated by a barrier division board placed in them last autumn) will be recorded as two hives. 7.3 Goal:To eradicate varroa mite during the next 24 months, but in 12 months time reassess the situation and make a decision at that time as to what changes should be made, if any, to the eradication programme.Any hives found to be infected with varroa mites or within 7.5km radius of that find (or 15km for highly infected hives will be eradicated. Once eradication has taken place equipment can be treated as stated earlier. 7.4 Te PukeThat the farmed hives and feral colonies in the Te Puke infected area should be eradicated before pollination. Providing eradication is successful and not many mites are found in ferals, the subsequent hives used for pollination of these orchards should not be depopulated. These hives are only to be moved into the buffer zone, and not moved again until after 1st August. Hives to be tested twice following removal from the Orchard, at not less than 3 months apart. If mites found depopulation of hives within the required radius to be carried out. 7.5 TracingAll hives to be given a unique New Zealand number and these numbers to be recorded before moving hives out of an apiary. 7.6 TimingAll varroa infected farmed hives to be depopulated immediately, and feral colonies in Te Puke to be killed by walking, finding and destroying. Samples to be taken whenever possible and by a poisoning programme if deemed necessary, up to a 7.5km radius from lightly infected apiaries. 15km radius from heavily infected apiaries. The other small outbreaks in Rawene north of Auckland, Te Kauwhata north of Huntly, Te Rore north of Te Awamutu and Raurimu at Tongariro National Park (if it is still considered positive), Tapu north of Thames and one other site just north of Thames, are unlikely to have many, if any, infected colonies at this stage and should be treated as above. The Army could be used to eradicate ferals in difficult terrain, such as just north of Thames. This site will also probably require poisoning because of the difficult terrain. 7.7 Auckland-Hauraki PlainsThe beehives and feral colonies in the Auckland - Hauraki Plains Infected zones should be immediately depopulated. The hives that are to be placed into pollination should then be depopulated. The depopulation should then carry on with ferals until the 1st August 2001, at which point progress reviewed and decision made on future programme. It will be relatively easy to deal with ferals in the Hauraki Plains compared with Auckland. A few feral colonies may have varroa mites in the Hauraki Plains area. The Hauraki Plains could have varroa eradicated by spring. 7.8 AucklandThe Auckland area will be the most difficult area to eradicate varroa and it will take more time to eradicate from the Auckland area than from any other area. But the big advantage of Auckland because of its geographic position with its narrow neck of land with seas on each side is that it will be relatively east to 'fence off' from the rest of the North Island. 7.9 NotificationAll beekeepers and owners of apiaries within a 7.5km radius of an established varroa find, or 15km radius from a heavily infested site, to be notified by AgriQuality and asked for the exact hive numbers currently on each site. This is to be audited by AgriQuality to confirm numbers and that no hives have been shifted in or shifted out and that the beekeeper has placed on each hive a unique beehive identification number. Also to check on any illegal movements of hives. At the same time as above, exact and detailed depopulation area maps to be publicly notified in local papers. 7.10 Operational ProcedureHives to be placed into controlled atmosphere chillers to kill all bees and varroa, one in each Eradication Zone. If unable to hire, hire reefer containers with mobile controlled atmosphere units to be brought into each area of eradication. Use of methyl bromide in controlled atmosphere chiller would be acceptable. 7.10.1 Shifting HivesAll hives with live bees or the owners and local branch members to assist, at a price to be negotiated between parties should shift dead hives, into the controlled atmosphere chillers. All shifting into these controlled atmosphere units to be done at night. Beehives to be left in units until mites are dead, plus same time again. 7.10.2 IdentificationAll hive numbers are to be checked into the chiller units and invoices made out by the contracting personnel and signed by the owner. Hives to be date stamped as they are placed in these units. 7.10.3 Handling Mite Free EquipmentFrom the Controlled atmosphere chillers all gear to be stored (or to be used after four weeks), by beekeepers anywhere in the North Island, by permit. All transporting of hives or boxes must be done at night from these fumigation units to storage areas, and must be covered to stop any infected bees entering load. All cost of controlled atmosphere units to be met by the Government. 7.10.4 Compensation Paid For:Bees in registered hives, and the beekeepers work for delivering and taking hives away from the controlled atmosphere units, to be paid for at the rate of $150 per hive, by Government within 20 days of eradication. This $150 pays for the numbering of the hives, cartage to the controlled atmosphere unit, placing hives into the unit, picking up hives from the controlled atmosphere unit and transporting to the storage area at a later date, paying for the rental of the storage area, removing dead bees in storage area, vermin control, taking hives out into the field again, placing into apiary sites, purchase of 4 frame nucleus hive or package bees, and all associated costs to building up the strength of a production hive again. 7.10.5 Compensation Qualifications
7.10.6 ClaimsFor claims for loss of income for commercial beekeepers the following options are suggested:
7.11 AlternativesIf any products are found which will kill all varroa mites and not bees, then this could be applied in the same manner, but in the meantime all bees, varroa and brood, pollen mites, wax moth and any other living creatures are to be killed. 7.12 Sticky BoardsAll sticky boards to be checked by an approved Contractor. 8. ERADICATION OF FERAL COLONIES8.1 BackgroundFeral honeybee colonies are established from swarms emanating from other colonies. The density of feral colonies in any given area is influenced by climate and foraging potential of the area but most importantly by the number of suitable cavities available for
occupation and the number of other colonies in the area. Typical areas for feral colonies include native bush and shelterbelts with hollows in trees and buildings with gaps providing access to wall linings and ceiling cavities. 8.2 Eradication of Feral ColoniesPoisoning using bait stations is recommended in Auckland and probably other areas. This option has been chosen because it will deal with difficult to locate feral colonies in large and rugged areas of bush. This method will kill any unregistered colonies and any colony that may not have been killed during the depopulation operation. It will also kill colonies located high in trees that can be very difficult to find and access. On-foot eradication will also be required so samples can be collected and the effect of poisoning observed. 8.3 Definition of Eradication ZoneThe area from which feral colonies will be eradicated will be the same as the area within which managed colonies will be depopulated. This is the area referred to as the Eradication Zone. That is, the area covered by drawing a 15 kilometre radius around every heavily Infected Place or 7.5km around lightly Infected Places. The area from which registered colonies will be depopulated will consist of:
8.4 Exclusion ZoneAn exclusion zone of a further 5 kilometre radius will be needed around the outside perimeter of the Eradication Zone. Beekeepers will be advised to remove beehives, under permit, from this area to prevent these hives also being poisoned. 8.5 Discussion of OptionsThere are two options worth considering for eradication of feral colonies: 8.6 Search and DestroyGround searching and appeals to the public and landowners for information will locate many feral colonies that can be destroyed by the application of a small amount of insecticide such as Carbaryl. This will be carried out in the Te Puke area. As of 11/5/00, members of the public had volunteered information on the location of 279 feral colonies, in the Infected Area, to the Operations Centre. This would be only a small proportion of the actual number. This may be carried out in the Te Puke area. 8.7 Poisoning Using Bait StationsBees can be attracted to bait stations provided attractive bait such as honey is used. Successful foraging bees recruit other bees to feed from the bait station. If a non-repellent, slow-acting poison is included in the bait, sufficient will be carried back to the colony to destroy it. 8.8 Operating ProcedureA grid of bait stations containing poisoned bait will be established at 1 km intervals throughout the Eradication Zone. These will be checked at regular intervals and the bait changed or replenished as required. Baiting would cease in any area three months after the last observed honeybee activity. 8.8.1 Timing of Feral EradicationThe feral eradication programme would start as soon as registered hive depopulation was completed. This is anticipated to be about the beginning of August 2000. Spring and early summer are the ideal times for this as bees are hungry and actively foraging. The
objective would be to have the Eradication Zone bee-free by the end of March 2001. Earlier for other than the Auckland zone. 8.8.2 BaitBait will be honey mixed with a poison such as acephate (Orthene) or sulfuramid (Finitron). These are recommended as they are slow acting, non-repellent to bees and have low mammalian toxicity. The honey will be tested to ensure it is free of AFB spores as there is a chance that some of this honey will be robbed out of dead feral colonies and end up in managed hives after repopulation. The honey will also be dyed to reduce the possibility that it will be consumed by people. The addition of a queen bee pheromone or beeswax to the bait station may increase attractiveness to bees (this will be tested before the start of the programme). Bait will be contained in pre-packed screw top plastic jars for ease of use and safety of transport. 8.8.3 ServicingPre-baiting of stations with non-toxic bait is not required but non-toxic honey could be incorporated on top of the toxic bait if creamed or crystallised honey was used. Bait stations will initially be checked at one-week intervals. Any old bait remaining will be removed and replaced with a container of fresh bait. Bait remaining longer than two weeks is likely to ferment and be less attractive to bees. The quantity of bait eaten will be recorded as a measure of bee activity in the area. As the bee population in an area declined, the frequency of servicing will be reduced in that area. 8.8.4 Determining Area Freedom From BeesBait station servicing staff will be required during their servicing runs to stop and inspect areas containing flowers to check for the presence of foraging bees. An area will be deemed to be free of honeybees' three months after the last bee activity is observed. It has been suggested that members of the public should be asked to report the presence of bees. It is our experience that many people cannot distinguish between bees, wasps and various look alike flies, which means that the Operations Centre would be inundated with many incorrect reports of sightings. However, it would be worth considering an appeal for information from the public toward the end of the operation. Feral colonies whose locations are known will be used as monitors and will be checked at the end of the baiting programme to ensure that they are dead. 8.8.5 Safety IssuesEach station will carry a warning sign. Occupiers of properties containing bait stations will be given written information describing the programme and any safety issues. Poisoned bait will be carried and placed in the stations in screw top jars so it will not be touched by bait station servicing staff. 8.9 Baiting Programme DirectionBaiting will start at the edges of the Eradication Zone and move progressively toward the centre. Baiting around areas requiring hives to be brought in for pollination will be timed as much as possible to take place before or after pollination. 8.10 Management of Pollination IssuesThe baiting programme in areas of significant kiwifruit production will be managed as much as possible to reduce the risk of poisoning hives brought into the area for pollination purposes. This could be done by pulling out, over the pollination period, bait stations located close to orchards, or timing baiting of those areas to take place after pollination. It may not be possible to manage baiting round minor crops occupying small areas, as this may be too disruptive to the programme and put its objectives at risk. Some allowance will have to be made for compensation for loss of production to cover these cases. Many crops currently receive "free pollination" (i.e., pollination is provided by bees from registered hives located in the vicinity for honey production or nearby feral colonies). After depopulation of registered colonies and eradication of ferals, bees will have to be brought in to pollinate these crops. It is recommended that these growers be expected to pay a commercial price for this service and not be compensated for any extra cost involved. However, the hives brought in to provide this pollination will have to be destroyed so the owner of the hives will be eligible for compensation for the cost of repopulating those hives on the same basis as other registered hives depopulated in the Eradication Zone. 8.11 Programme ManagementThe programme will be managed from an Operations Centre with sufficient staff to recruit and train bait station operators, plan run servicing, enter run records in the database, and administer stores and wages, etc. 8.11.1 DatabaseA database will be developed to record and track bait station monitoring progress. This will be able to produce summary reports and data for mapping. 78.11.2 ReportingReports on progress of the feral eradication programme will be supplied to the NBA and MAF as required. 8.11.3 AuditAn internal audit programme covering the following areas will be developed to ensure consistency and maintenance of standards:
The following forms will be developed:
8.11.4 Work InstructionsWork instructions for the following activities will be produced:
8.12 Preferred Bait Station OperatorsIt is recommended that preference is given to employing beekeepers and their employees affected by the eradication programme that would otherwise be unemployed. 8.12.1 TrainingA hands-on, practical training programme will be developed to train bait station operators. This will cover correct bait station servicing, safety, public relations and accurate record keeping. It is envisioned that access to property to place bait stations will be by consent so bait station operators will not require warranting under the Biosecurity Act. Some of the operations management staff will be Authorised Persons under the Biosecurity Act who will have authority to deal with the expected few cases where access to a required property is denied. Occupiers of land where bait stations are sited will be asked to sign a document stating that they understand that the bait station contains a poisoned bait, that they agree to have it located on their property, that they will allow access for servicing, that they will not interfere with it and that they will inform the Operations Centre if the bait station becomes damaged. 8.14 Management of Pollination IssuesSince it is assumed that the depopulation programme will be concluded before any significant pollination of horticultural crops is required in the spring of 2000, there is no requirement for the management of pollination issues other than depopulation of hives used for paid pollination. All crop pollination is expected to be in the form of paid pollination services. No compensation will be paid where paid pollination services were not previously required. 8.15 Database and RecordsThe existing Apiary Register database will be used to identify apiaries to be depopulated and record depopulation activity. A file will be maintained of all depopulated apiary inventories. 8.15.1 ReportingReports of the number of apiaries and hives depopulated will be supplied to the NBA and MAF as required. 8.15.2 AuditAn internal audit programme covering the following areas will be developed to ensure consistency and maintenance of standards:
8.16 Summary of Issues to Be Resolved
9. RE-POPULATION OF REGISTERED HIVES9.1 BackgroundThe need to repopulate registered hives depopulated during the varroa eradication programme stems from compensation provisions of Section 149 of the Biosecurity Act, namely that a person with goods destroyed as a result of anything done to eradicate the pest is entitled to compensation of such an amount that the person will be in no better or worse position than any person who is not directly affected by the action taken. Beekeeping activities should be allowed to begin again once it has been determined that no feral colonies exist within the Zone, and indeed repopulated hives kept within Zone will be required to act as surveillance hives to establish whether the eradication programme has been successful, and whether any "hot spots" need to be re-worked.
9.2 Timing of RepopulationThe timing of repopulation is driven by the length of time taken to eradicate all feral colonies within the Zone, together with a sufficient length of time to ensure no mites in dead feral colonies remain alive at the time repopulation occurs. It is therefore recommended the "all clear" period before repopulation is no shorter than 6 weeks.
9.3 Source of Nuclei and PackagesIt is recommended that beekeepers source their replacement bees on the open market. However, because of the numbers likely to be required it is recommended that the NBA, at national or branch level, organise numbers and sources of supply. The American Foulbrood Pest Management Strategy contains provision that should ensure that no bees made available for repopulation come from hives with a clinical case of American Foulbrood.
9.4 Testing of Nuclei and PackagesAll nuclei and packages produced in the Buffer Zone to be tested for varroa immediately prior to sale to another beekeeper. 10. MOVEMENT CONTROL10.1 BackgroundMovement control involves 4 distinctly different zones; the Eradication Zone (15km around any heavily infested apiary); the Buffer Zone (the northern half of the North Island excluding the Eradication Zone); the Surveillance Zone (the southern half of the North Island); the Disease Free Zone (all of the South Island). Each zone will be treated separately and different movement controls will be required because of the different level of risk posed.
10.2 Strict Movement ControlStrict movement control based on zones of risk, which is similar to the regime currently being used in the delimiting survey, was also considered. It was felt that such a regime provides a simpler system to both administer and comply with, and is already well understood and accepted in the current circumstances by beekeepers. From an epidemiological point of view, the system treats all beehives equally according to risk, and does not impose as many restrictions on beehives or beekeepers who are not high risk (i.e.,those in the Surveillance Zone). Finally, the system is likely to be no more costly than the Accreditation option. Strict movement control with hive testing is therefore the recommended option.
10.3 Critical LineNo hives of bees should be allowed to be shifted from the Buffer zone to the Surveillance zone. 10.4 Restricted Hive MovementAll hive and bee movements to cease in the Infected and Buffer zones for 7 months starting 1 January, ending 1 August 2001. Movement of hives may be allowed under exceptional circumstances, under strict permit controls.
10.5 Restricted Bee MovementIn the buffer zone, all boxes of combs to be delivered by trucks to apiaries at night, so avoiding movement of bees, or by daylight hours in a closed truck in which bees can be eradicated between apiaries. All honey to be placed in closed truck in which bees can be eradicated, before arriving at the next apiary. Compensation will be paid for costs incurred in achieving this.
10.6 Cell RaisingAll raising of cells to be done in a manner by which no bees are moved from one apiary to another.
10.7 Bee ExportsAll exports of live bees from the North Island will cease for one year. Compensation will be paid for loss of income.
10.8 Illegal Hive Movement sAll illegal hive movement or bee movement to be taken very seriously and prosecutions to be made by the Ministry of Agriculture and Forestry.
10.9 American FoulbroodAll AFB hives to be burnt on site wherever possible, otherwise destroyed, wrapped and transported in a sealed van to point of burning.
10.10 Eradication Zone Before and During EradicationMovement in the Eradication Zone is currently prohibited except where allowed under permit. These restrictions will remain in place until eradication has been completed. Before eradication has been carried out hives may be moved in to the Eradication Zone, under permit, for pollination purposes. None of these hives will be allowed out and all will be depopulated on completion of the pollination contract (these hives will be treated in the same way as any other depopulated hives for compensation purposes), other than the Te Puke area which may be treated differently.
10.11 Eradication Zone after DepopulationAfter depopulation has been completed and the all clear given to repopulate hives, movement will be permitted in the same way as described below for the Buffer Zone.
10.12 Surveillance ZoneFree movement will be allowed within the Surveillance Zone. Any hives moved in to the Buffer or Eradication Zone will not be allowed back in to the Surveillance Zone and will be subject to twice yearly testing.
10.13 South Island - Disease Free ZoneMovement will be unrestricted except that no movement from any part of the North Island will be allowed.
10.14 Duration of RestrictionsThe movement restrictions will be reviewed annually by a group representing the MAF and Beekeeping Industry. Movement restrictions will be eased if good progress with eradication is achieved. Some movement restriction will remain in place until country freedom status is regained.
10.15 Restrictions Applying to Beekeepers with Hives in More than One ZoneBeekeepers in this situation to operate under an agreed management plan under which they describe how they isolate or minimise the risk of moving potentially infected material from an area of high risk to an area of lower risk. Any such agreement will be subject to audit by the Operations Centre.
10.16 Consultation with IndustryAn industry consultation process will be set up to assist with any alterations and amendments to the detail of the movement control restrictions. This process will take account of changes and unforeseen circumstances.
10.17 Dealing with Disputes and Contentious IssuesA process will be negotiated with MAF and the NBA on how these issues will be handled. This will be documented and included in operating procedures.
10.18 Management of the Movement Control FunctionFor acceptability it is important to ensure consistency in the application of movement restrictions. For this reason centralised control of the function is desirable. A Movement Control Manager will be appointed to the Operations Centre. This may not always be a full time role, as the workload will vary seasonally and according to programme development. Movement control officers will be appointed as required to assist. Movement permits will be issued on MAF letterhead and signed by properly Authorised Persons under the Biosecurity Act. Applications will be requested on an approved application form to ensure that all of the necessary detail is provided. Where possible issued permits will be faxed or emailed to the beekeeper. Copies of all permits issued will be filed along with the application form and any other relevant documentation. 10.19 Work InstructionsWork instructions will be produced for the following activities:
10.20 Internal AuditThe movement control function will be subject to a programme of
regular internal audit. 10.21 TrainingMovement control staff will be those who have already had some experience in this role or will be trained on the job by an experienced operator. A training checklist will be produced to assist with this. Administration of movement control of bees and bee products requires a good knowledge of the beekeeping industry and beekeeping jargon. Where movement control staff have not yet gained this experience a person with apiculture experience will be assigned to assist them. 10.22 FormsThe following forms will be further developed: 10.23 ReportingA report will be provided to MAF and the NBA summarising permitted activity as required as any changes made. 11. NORTH TO SOUTH MOVEMENT BANMaintaining varroa-free status in the South Island has significant advantages for the New Zealand beekeeping, horticultural and agricultural industries in general, and the South Island components of those industries in particular. 11.1 Varroa Free South Island Essential To EconomyMaintenance of varroa-free status for the South Island is very important since beekeeping in much of the area is reliant solely on honey production (less diversification options available), and since the honey produced (clover) is often lower in value than specialty honeys. Much of this beekeeping is carried out on marginal dryland pasture or high country, which in turn are more dependent on clover pollination from honeybees to maintain high quality forage for stock production. 11.2 Varroa Free South Island Essential To Beekeeping ViabilityDownstream varroa impact is likely to be much greater in these South Island pasture areas than in paid pollination areas of New Zealand, since control costs cannot easily be passed on (little paid pollination services), and since beekeeping enterprises may not be able to absorb significant cost increases if varroa becomes established in the South Island, unless low cost control measures are developed and/or the price of clover honey increases dramatically, beekeeping in most areas of the Island may well become uneconomic. 11.3 North - South Border ControlFFor a South Island quarantine to be successful, North Island beekeepers will follow established movement control rules for risk materials they may wish to send to the South Island. At the same time, transport operators will need to be made aware of the ban on a periodic basis, since they are likely to be the first line of surveillance if movement control rules are broken. There will also need to be on-going publicity of the reasons for the movement control rules to beekeepers, transport operators and to a lessor extent the public in general. It is assumed that border surveillance for goods coming into the South Island from outside New Zealand will be increased in an effort to prevent another incursion of the mite from offshore.
11.3.1 Movement Control RestrictionsThe following movement control restrictions will be enforced:
11.3.2 Transport Operator CommunicationSince transport operators will be a first line of surveillance for any breaches of movement control restrictions and on-going communication and publicity to those operators about the programme is essential. A list of operators (name, address, phone/fax/email, and contact person) will be established and the list will be updated continually. A written communication 4 times per year outlining movement control restrictions and who to contact in case of a breach will be provided. A poster (see below) will be sent to each operator once per year with instructions that it be hung in a conspicuous place (e.g., lunch room) on the operator premises. 11.3.3 PublicityA publicity campaign on the reasons for the movement control restrictions will be put in place. The campaign will be targeted at persons most likely to be involved in movement of risk goods. The general public will also be targeted because they are also likely to be transporting such goods. To this end signs will be placed at ferry terminals and wharves to request people to check their vehicles for live bees before embarkation. Six articles per year will be produced and published in the New Zealand Beekeeper magazine. Three articles per year will be produced and published in transport industry trade magazines to be produced by expert beekeepers in the field. A poster will be designed and distributed each year to 600 outlets in both islands associated with the beekeeping industry (beekeeping supply outlets, honey buyers), the transport industry (operator premises/depots, truck stops, ferry terminals, shipping terminals), the travel industry (travel agents, car rentals) and florists and flower auction houses that import flowers from the North Island. Cut flowers have been known to contain live bees after in island transport.
11.3.4 Public RelationsTransport operators may be reluctant to act as a surveillance point for the programme. It will be important to establish good relations with these operators, and public relations activities will be undertaken to get them to understand the "public good" reasons for the programme. North Island commercial queen producers who normally supply part of their production to South Island beekeepers will be adversely affected by the movement control restrictions. There are no good figures on the size of this market, but the affect will be limited to a small number of North Island producers (approximately 5-7). It is recommended that compensation be paid to these queen producers based on an independent analysis of their sales records for the previous 3 years.
12. SURVEILLANCE12.1 BackgroundOn-going surveillance during and after eradication is required to provide information on the status of zones, beekeepers and apiary sites, and to determine the success of the programme in achieving its objective. The information obtained is used for a variety of purposes such as delimiting the geographic spread of the infection, proof of zonal freedom, and for pre-movement and export purposes. If eradication is to succeed the surveillance regime must be sensitive enough to be able to detect any low levels of mites in hives to minimise the likely spread to another apiary. At the time of writing, NCDI were still working to more accurately define test sensitivity. The surveillance regime described below may have to be modified if the test level is found to be inadequate. 12.2 Definition of Surveillance ZonesThe surveillance zones are the same as for movement control, namely:
12.3 Miticide Strips, Application, PaymentSurveillance is to be carried out by beekeepers under contractor supervision and are to be provided with free sticky boards and Miticide strips so they can test all their own hives, they will be paid $10 per hive for motor vehicle running costs and for the placement and removal of the sticky boards and strips. These to be left in the hives for 2 days. All miticide strips to be returned. Use of miticide strips to be audited. All hives within a 20km radius of a positive find to have the most effective method of finding varroa mites immediately used on them. Apiaries to be tested twice in 6 months.
12.4 Surveillance Based on RiskThis was examined and appeared to satisfy both epidemiological and statistical analysis requirements. Surveillance is on going and universal in both the Eradication and Buffer Zones, and lesser and randomised in the Surveillance Zone and Disease Free Zone. Surveillance based on risk is therefore the recommended option.
12.5 Operational Procedures12.5.1 Summary of Surveillance StrategyThe following surveillance strategy programme will be carried out in the various zones:
