A NOVEL ATTRACT-AND-KILL APPROACH FOR MANAGING THE INVASIVE PEST SPOTTED WING DROSOPHILA IN MULTIPLE SMALL FRUIT CROPS

Description

This project will develop novel behaviorally-based approaches for monitoring and managing the invasive pest spotted wing drosophila (SWD) (Drosophila suzukii) in small fruit crops. Small fruit crops are a multi-million dollar industry in the northeast US, where SWD has become a key pest since it was first detected in 2011. Current management practices rely on conventional applications of insecticides. These pesticides are subject to rigorous restrictions due to environmental and health concerns. Development of new alternatives is desperately needed to maintain sustainable farms. Existing management strategies will benefit from cost-effective, easy-to-use, and sensitive monitoring and management tools for SWD.We will develop an attract-and-kill approach that is based on a combination of olfactory (fruit-based) and visual cues and a killing agent. Specific objectives are to: identify fruit-based attractants for SWD, identify visual cues important in host location, combine chemical (fruit-based) and visual cues for an attract-and-kill approach, and actively promote outreach and information exchange among stakeholder groups. Studies will be conducted in the laboratory and field to test a prototype attract-and-kill device-attracticidal spheres, originally developed to manage apple maggot flies, with the ultimate goal of reducing insecticide use, protect humans and the environment from insecticides, and prevent the onset of resistant populations. This multi-state (New Jersey/Maryland/West Virginia), multi-crop (blueberries/raspberries), and interdisciplinary (entomologists/chemists/industry)resarch addresses many of the Regional IPM Competitive Grants Program, Northeastern Region, priorities as well as stakeholder needs.
