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.

摘要

铃木果蝇（Matsumura）是一种软皮水果的入侵害虫。由于其引进时间较晚，目前阿根廷尚无对其化学防治的研究。本研究的目的是在实验室条件下评估五种不同作用方式的制剂杀虫剂对铃木虫卵、幼虫和成虫的作用。用多杀菌素配制的产品是最有效的杀虫剂，因为它对所有生命阶段都表现出高效。此外，接触多杀菌素和高效氯氟氰菊酯的雌性产卵较少。需要进行进一步的研究，以在现场条件下证实这些结果。
