摘要: 目的研究不同浓度的净普力对不同卵龄的致乏库蚊、白纹伊蚊杀灭效果及其作用机理。方法浸渍法与显微电镜技术。结果4种不同浓度的净普力在3种不同的作用时间(24h、4h、0.5h)下对致乏库蚊卵、白纹伊蚊卵杀灭效果差异有极显著性(P<0.01),净普力对不同卵龄的致乏库蚊杀灭效果差异亦具有极显著性(P<0.01)。在扫描电镜下,受到药物作用与未受药物作用的致乏库蚊卵外形无差异,但在透射电镜下,受到药物作用的致乏库蚊卵内胚胎组织的胎膜成颗粒状,内部组织溶解。结论净普力对蚊卵具有一定杀灭效果,由电镜结果可初步确定净普力可杀死蚊卵内的胚胎。

Abstract: Objective To demonstrate the effect of zymplex against different stages of the Culex quinquefasciatus,Ades albopictus eggs treated with different zymplex concentration with different treated time and its mechanism.Methods Immersions method and electronic microscopy.Results F-test showed that the effect of zymplex against the eggs treated with 4 concentration in 3 different times( 24 h,4 h,0.5 h) were different significantly.The effect of zymplex against different stages of the Culex quinquefasciatus eggs were different significantly.After treated,Culex quinquefasciatus eggs showed no outer appearance difference from control through SEM,while their embryo membrane was grain-shaped with it internal tissue dissolved by TEM.Conclusion Zymplex had some certain drug effect on eggs.It could kill the embryos of the eggs.
