Management of Spotted Wing Drosophila using Organic Strategies

This webinar took place on February 1, 2017.

About the Webinar

Spotted wing drosophila (SWD) has emerged as a devastating pest of small and stone fruits worldwide. Losses due to SWD can be as high as 100% and have been valued more than $718 million annually in the U.S. The zero tolerance for SWD in fresh fruit has led conventional growers to make preventative insecticide applications when fruit are ripe. Organic management of SWD is even more challenging due to the low number of effective OMRI-approved materials and limited understanding on the biology of SWD to translate into non-chemical management tactics. In 2015, a multi-regional project was funded by USDA-NIFA through Organic Agriculture Research and Extension Initiative (OREI) to develop, evaluate and implement systems-based organic management programs for SWD.

This webinar will provide a comprehensive update on organic management of spotted wing drosophila. It will cover findings of the research conducted during the first year of this project on organically approved strategies including: 1) behavioral strategies to improve monitoring (using more attractive baits and lures) and management (attract and kill approach); 2) cultural strategies to lower SWD populations in the field (canopy and floor management, and using exclusion netting); and 3) chemical strategies (using organically approved insecticides in combination with adjuvants and phagostimulants.
