| 摘 要： | 环氧虫啶是我国自主研发的一种新型的新烟碱杀虫剂,主要用于防治刺吸式口器害虫。本文采用点滴法测定了环氧虫啶对中黑盲蝽、苜蓿盲蝽、三点盲蝽的毒力,结果表明,三种盲蝽对环氧虫啶均具有较高的敏感性,其中中黑盲蝽的敏感性最高,LD_(50)值为2.03ng/头,其次为苜蓿盲蝽和三点盲蝽,LD_(50)分别为3.12和3.34ng/头。多功能氧化酶抑制剂PBO能明显增加环氧虫啶对三种盲蝽的毒力,谷胱甘肽S-转移酶抑制剂DEM只在中黑盲蝽上对环氧虫啶表现出增效作用,而羧酸酯酶抑制剂TPP未显示增效作用。这说明,环氧虫啶具有防治苜蓿盲蝽属三种害虫的应用潜力,细胞色素P450-单加氧酶可能在环氧虫啶代谢中起重要作用。

| Abstract: | Cycloxaprid is a novel self-developed neonicotinoid insecticide for the control of sucking insect pests. Three Adelphocoris species (Hemiptera: Miridae), A. suturalis, A. lineolatus, and A.fasciaticollis, are important insect pests in cotton, alfalfa and other crops in China. Bioassays of cycloxaprid showed that A.suturalis (LD50: 2.03 ng/adult) was more susceptible to cycloxaprid than A. lineolatus and A. fasciaticollis with LD50 values of 3.12 and 3.34 ng/adult, respectively. The toxicity of cycloxaprid to three Adelphocoris species could be synergized by piperonyl butoxide (PBO), but generally not by TPP. Inhibitor of glutathione S-transferase (GST), the DEM, showed synergism only to cycloxaprid against A.suturalis. The results suggest that cycloxaprid is a candidate for controlling Adelphocoris species. Cytochrome P450-dependent monooxygenase might play an important role in the metabolism of cycloxaprid in these three mirid bugs. |
