Managing An Invasive Drosophilid Species In Agriculture Using Innovative Behavioral Manipulation Strategies

Project Details

Description

This project addresses the following the USDA Crop Protection and Pest Management Competitive Grants Program priority: 'develop innovative, ecologically-based, sustainable IPM strategies and systems and enhance their adoption.' Non-native species are classified as 'invasive' based on the economic and ecological damage they inflict. The spotted wing drosophila (SWD), Drosophila suzukii, is an invasive Asian insect pest accidently introduced into the continental United States in 2008. Since then, it has been detected in a total of 41 states from California to Maine as well as Canada, Mexico, Europe, and South America. SWD attacks a wide variety of fruit including small fruit such as caneberries, blueberries, and strawberries. Presently, growers rely on a single management strategy - aggressive insecticide applications. Development of innovative behavioral manipulation strategies offers a promising and sustainable means to manage SWD. The overall goal is to develop an attract-and-kill approach, i.e., attracticidal spheres, and combine this technology with repellents in push-pull strategies in whole-system behavioral management programs for the invasive SWD as alternatives to frequent, full cover insecticide sprays. Specifically, we plan to: identify and evaluate the most effective attractants and repellents for SWD, optimize attracticidal units for SWD, investigate and optimize behavior-based approaches to manage SWD under laboratory and field conditions, and disseminate information to stakeholders. Our approach will reduce the likelihood of insecticide resistance development, reduce negative impacts on biological control agents to restore integrated pest management to the affected crops, and provide tools that greatly reduce or eliminate the need for repeated insecticide applications. The results will reduce risks and increase sustainability and profitability of an industry currently jeopardized by this invasive species.
