Evaluation of insecticides against the invasive pest Drosophila suzukii (Diptera: Drosophilidae) under laboratory conditions

Abstract

Drosophila suzukii (Matsumura) is an invasive pest of soft-skin fruits. Due to its recent introduction, there are currently no studies about its chemical control in Argentina. The aim of this research was to evaluate five formulated insecticides with different mode of action against eggs, larvae and adults of D. suzukii under laboratory conditions. The product formulated with spinosad was the most effective insecticide, since it showed high efficacy against all life stages. Furthermore, females exposed to spinosad and lambda-cyhalothrin laid fewer eggs. Further studies need to be conducted in order to corroborate these results under field conditions.
