摘要: 目的 了解山东省不同地区淡色库蚊成蚊对溴氰菊酯抗性与kdr等位基因的突变关联情况。方法 采用AS-PCR(allele-specific PCR)技术, 检测不同种群淡色库蚊成蚊的kdr等位基因频率。结果 成蚊接触筒检测济南、济宁和青岛地区的淡色库蚊雌蚊, 其死亡率分别为39.62%、37.25%和83.81%;通过回归分析AS-PCR检测的kdr等位基因频率结果, 显示不同地区淡色库蚊对溴氰菊酯抗性L1014F型和L1014S型突变表型与kdr等位基因频率有明显的相关性。结论 淡色库蚊kdr基因突变与溴氰菊酯抗药性表型呈正相关, AS-PCR方法对于检测kdr等位基因的可行性亟待验证性研究。

Abstract: Objective To investigate the association of kdr gene mutation with deltamethrin resistance in adult Culex pipiens pallens from different regions in Shandong province, China. Methods The frequency of each kdr allele in different populations of adult Cx. pipiens pallens was determined by allele-specific PCR (AS-PCR). Results The mortality rates of female Cx. pipiens pallens from Jinan, Jining, and Qingdao in Shandong were 39.62%, 37.25%, and 83.81%, respectively, as measured by adult mosquito contact tube. There was significant correlation between deltamethrin resistance mutation phenotypes of L1014F and L1014S and frequencies of kdr alleles in Cx. pipiens pallens from different regions, according to the regression analysis of AS-PCR results. Conclusion Mutation of kdr gene is positively correlated with deltamethrin resistance phenotypes in Cx. pipiens pallens. The feasibility of the AS-PCR method for detection of kdr allele needs further validation.
