Sucrose improves insecticide activity against Drosophila suzukii

US Scientists have demonstrated that the addition of sucrose as a phagostimulant improves the activity of several insecticides to target spotted wing drosophila (Drosophila suzukii) adults and improve protection of fruit from infestation.

The enhancement in activity of several reduced risk insecticides, such as spinosyns, cyantraniliprole, and acetamiprid, provided equivalent or superior protection of blueberry and strawberry fruits when compared with application of conventional insecticides. Adoption of insecticide programs based on reduced risk insecticides applied with phagostimulants should reduce the broad spectrum environmental toxicity associated with the over reliance on organophosphates and pyrethroids for managing D. suzukii.
