Temperature alters the response to insecticides in Drosophila suzukii (Diptera: Drosophilidae)
Journal of Economic Entomology 111 (3), 1306-1312
Abstract: Drosophila suzukii Matsumura (Diptera: Drosophilidae) is an invasive pest in Europe and is a major threat to the soft fruit industry. Because of an ample temperature range, the pest spans from low to high elevation crops in mountain areas of the Southern Alps. Starting from field observations on the variable efficacy of insecticides under different temperatures, experiments were designed to test the efficacy of chemical families of insecticides available against this pest. Pyrethroids and spynosins proved to be the most effective under all temperature conditions (14, 22, and 30°C) in all assays. Organophosphates and neonicotinoids showed significantly lower efficacy at low temperatures, indicating that they are not suitable to protect crops under those conditions. The management of the pest in cold habitats, which are suitable for the cultivation of high-quality berries as for example in mountain farming systems, is constrained by a limited number of molecules available for fruit protection. Temperature has to be considered among factors affecting the decision-making process for the choice of registered formulations to be used in pest control.
