大阪府における各種作物に発生したオンブバッタ属２種の構成比と外来種アカハネオンブバッタに対する薬剤の殺虫効果

抄録

In 2020, we surveyed the relative abundance of a native grasshopper, Atractomorpha lata (Motschoulsky), and an exotic congener, A. sinensis sinensis Bolívar, on agricultural crops, including eggplant, cockscomb, Chinese cabbage, and crown daisy, in Habikino City, Osaka Prefecture, and found that A. sinensis sinensis was predominant on all investigated crops. In addition, we assessed the toxicity of nine insecticides against A. sinensis sinensis adults collected in Habikino City using the cabbage leaf-dipping method, which revealed that MEP, fipronil, and tetraniliprole are the most effective insecticides against this grasshopper species.
