|BMSB: An Imminent Threat to Aust & NZ Workshop Proceedings 2017||PHA and B3||2017|
Plant Health Australia (PHA) and Better Border Biosecurity (B3), New Zealand held the Brown Marmorated Stink Bug: An Imminent Threat to Australia and New Zealand Workshop in Brisbane on 25th September, 2017. The workshop aimed to inform participants of activities being carried out in Australia and New Zealand on brown marmorated stink bug (BMSB). Participants were invited from the Australian and New Zealand governments, research organisations, funding bodies and industries. Speakers included representatives from the Australian Department of Agriculture and Water Resources, AUSVEG, Bio-Protection Research Centre New Zealand, Horticulture New Zealand, New Zealand Winegrowers, New Zealand Ministry for Primary Industries, Plant and Food Research New Zealand, Plant Health Australia and Better Border Biosecurity New Zealand. The plenary was delivered by Tim Haye (Centre for Agriculture and Bioscience International), who spoke about the international situation, BMSB biology and the use of biocontrol. The workshop was split into sessions on risk assessment pathways, detection methods, industry perspectives and management and a workshopping session. From the proceedings of the day a series of recommendations were developed as outlined below.
1. A repository for information on BMSB was seen as important by the workshop participants. Plant Health Australia has created a page on the biosecurity portal (biosecurityportal.org.au/Pages/BMSB-Landing.aspx).
2. The lures available for BMSB are based on aggregation pheromones and a synergist. These lures are considered to be effective for pest management but not for border surveillance. Based on the large amount of research investigating lures it seems unlikely that more effective lures can be found in the near future.
3. A surveillance strategy should be developed for Australia in consultation with work being undertaken in New Zealand.
4. Australia and New Zealand should continue to work to pre-register chemical controls (emergency permits) for BMSB prior to an incursion.
5. New Zealand is undertaking research to investigate biocontrol agents. Part of this assessment has tested some Australian native stink bugs which have been identified as susceptible to the most promising agent (samurai wasp). Work should be initiated in Australia to investigate the use of biocontrol agents as a preparedness measure for BMSB.
6. There are various models for predicting regions in which BMSB will establish in Australia and New Zealand, however, they provide conflicting information. However, they are indicate the risk of establishment for large parts of Australia and New Zealand. Improved information on areas BMSB could establish may better target risk assessment.
7. A greater understanding of BMSB biology might be useful including triggers for long distance dispersal and the biological differences between the tropical and temperate forms of BMSB.
8. A study to determine the effect of BMSB on Australian and New Zealand native plant species could be carried out in a country where BMSB is present. Such a study could include information in preferences of BMSB on native species over crop plants and weed species and could involve the International Plant Sentinel Network.
