摘要 目的建立可靠的中华按蚊拟除虫菊酯击倒抗性的PCR检测方法。方法基于课题组前期研究发现的拟除虫菊酯抗性中华按蚊钠离子通道蛋白(VGSC)L1014位点的突变机制,即TTG突变为TTT和TGT,设计特异AS-PCR引物,进行中华按蚊拟除虫菊酯杀虫剂抗性突变检测。结果设计的AS-PCR引物和建立的反应体系可以分别扩增出现已发现的中华按蚊击倒抗性的TTG(T)杂合、TTT纯合、TG(T)G(T)杂合、TG(T)T杂合,PCR电泳图结果与测序图结果一致。结论成功建立中华按蚊击倒抗性突变的PCR检测方法,可用于现场中华按蚊的击倒抗性检测。 The objectie of the present research was to establish the PCR method for An.sinensis knockdown resistance detection.Based on the mutation mechanism of An.sinensis VGSC gene L1014 position,AS-PCR primers were designed to amplify the Kdr mutation and TTG(T) heterozygote,TTT homozygote,TG(T)G(T) heterozygote,TG(T)T heterozygote were successfully amplified and the PCR result was same to the result of gene sequencing.The AS-PCR method for An.sinensis knockdown resistance mutation detection was successfully established and could be used for field study ofAn.sinensis DDT and pyrethoids resistance detection.
