摘  要:
[目的]探明柑橘木虱在新烟碱类杀虫剂之间是否存在交互抗药性,为开发和应用这类杀虫剂提供依据。[方法]用药膜法测定了不同来源的柑橘木虱成虫对吡虫啉、噻虫嗪、呋虫胺的LC50、LC95和抗性指数。[结果]已对吡虫啉、啶虫脒产生抗药性的柑橘木虱种群,虽然从未施用过噻虫嗪、呋虫胺和其他新烟碱类杀虫剂,但对它们的抗性倍数也已达低抗至中等抗性水平。[结论]柑橘木虱在新烟碱类杀虫剂噻虫嗪、呋虫胺、吡虫啉、啶虫脒之间可能存在交互抗性。

摘  要:
To explore if Asian citrus psylla has cross-resistance between neonicotinoid insecticides,which will be the basis to develop and apply the pesticides.[Methods] Both LC50,LC95 of imidacloprid,thiamethoxam,dinotefuran and resistance index of citrus psyllid adults were determined with the drug film methods.[Results] Although citrus psylla population which had developed resistance to imidacloprid and acetamiprid had never been applied thiamethoxam,dinotefuran and others neonicotinoid,resistance to them has been reached a low to medial level.[Conclusions] Citrus psyllid may exists cross-resistance between the new neonicotinoid insecticide,thiamethoxam,dinotefuran,imidacloprid and acetamiprid.
