Leader: Professor Phil Lester, Victoria University of Wellington

Mission Statement

By providing end-users with the tools (and deployment strategies) to control current insect pest issues, and to combat new incursions of unwanted insects, this project will help reverse the decline of native biodiversity through a national partnership that moves beyond the current status quo to involve the best researchers and end-users for the task across the country.

Summary

Wasps stand out as one of the worst intractable pest problems in New Zealand, with massive impacts on iconic fauna and parts of the productive sector such as grape and citrus production. They are also a public health and nuisance issue. New tools for wasp control are one of the top ten research priority areas for regional government agencies, along with community and industry groups. This project aims to deliver a step-change in the management of wasps, shifting from the current “small site control” towards “landscape-scale eradication”. The project will develop four state-of-the-art technologies to combat wasps. Technology development will be complemented by two cross-cutting research strands: (1) development of an eradication strategy for wasps, utilising statistical methods to evaluate current and emerging control tools with a view to achieving eradication; and (2) an assessment of public perceptions and perspectives on the use of novel pest control strategies, in order to account for any strongly held concerns that might prevent adoption of new pest control tools. The views of Māori will be given particular consideration, given their status as tangata whenua with a long and intimate association with indigenous flora and fauna.

Co-develop four new technologies for insect control (with appropriate tactical, strategic, and end-user considerations), using the common wasp (Vespula vulgaris) as a test species and assess the economic feasibility, social acceptability and practicality of each technology for large-scale deployment.

  1. Can we develop novel genetic technologies (RNAi and mtDNA) to regulate wasp populations?
  2. Can we use ‘Trojan mites’ to deliver pathogens into wasp nests?
  3. Can we use smart dispensers to deliver pheromones or insecticides to wasps?
  4. Can we develop wasp eradication strategies?
