As part of phase two of our Insect Eradication project this research further refines the recommended techniques used against moth pests culminating in field verification trials against Light Brown Apple Moth (LBAM) in urban and orchard areas.

The aim of the project was to investigate the integration of innovative eradication technologies against LBAM as a model for the development of eradication strategies against other exotic moth pests. The main objective was the integration of the sterile insect technique and mating disruption using novel pheromone distribution technologies such as mobile mating disruption and SPLAT^TM (Specialized Pheromone and Lure Application Technology) in urban areas and vineyards.

Research outcomes:

Identification of irradiation dose for SIT, development and testing of mobile mating disruption, development and testing of SPLAT^TM in SA, NZ and WA, testing of integrated eradication in the field (SPLAT^TM + insecticide) and urban environment (SPLAT^TM +SIT), analysis of past eradications in Australia.

Transfer of technologies such as SPLAT^TM for eradication of pests from other insect orders needs to be investigated. Improvement in eradication efficiency through the development of mechanised application technology and improved formulation is highly likely with further input. Further research is required to develop softer eradication technologies for use in urban areas that can be integrated with pheromones.

Research implications:

New pheromone delivery technologies such as SPLAT^TM have the potential to become an important component of integrated eradication strategies in the future.

Eradication of arthropod harmful plant pest incursions has often relied on destructive technologies such as crop removal and broad spectrum pesticide application. This strategy incurs a significant cost to industry, the environment and the community. Alternative eradication strategies that reduce the economic and social impact need to be developed.

Research outcomes

Eradication technologies were reviewed including, documenting irradiation biology and inherited sterility of Light Brown Apple moth. The competiveness of sterile moths was tested and the integration of eradication technologies was also investigated.

Research implications

Sterile insect technique has an important role as a key part of new age eradication technologies but integration with pheromones and other eradication tools needs further study. which will be conducted in phase two of this project CRC40136: Insect Eradication.
