摘要: 目的:对室内选育的淡色库蚊抗溴氰菊酯品系(抗性系数518)进行遗传分析。方法:采用LC-P值分析法研究淡色库蚊溴氰菊酯抗性的形式遗传。采用抑制剂增效试验探讨抗性机制。结果:正交和反交F1代的抗性系数分别为154.8和159.2。F1代的LC-P线靠近抗性亲本一方,D=0.625;BC代在死亡率50%处、F2代在死亡率25%和75%处未出现明显平坡,BC和F2的实测曲线和理论曲线均存在较大差异,P均<0.01;PB、DEF和TPP对抗性品系的增效比分别为27.13、1.22和1.05。结论:淡色库蚊对溴氰菊酯的抗性为多基因遗传,其主要基因为不完全显性,多功能氧化酶是抗性的主要因子。

Abstract: AIM: To analyse the genetic character of deltamethrin resistant laboratory strain (resistant factor being 518) of Cx.pipiens pallens. METHODS: Genetic studies were made of deltamethrin susceptible and resistant strains of Cx.pipiens pallens with LC P curve contructed from the response of fourth instar larvae to deltamethrin treatment, and the resistance mechanisms were analysed with synergetic tests in PB, DEF and TPP. RESULTS: The resistant factors of F1 generation from cross and reciprocal ...
