摘要
目的探明合肥市中华按蚊对溴氰菊酯的抗性现状。方法选择合肥市肥东、肥西和长丰县,每县各选取1个自然村,于2011年7-8月采用牛诱和猪诱法捕获饱血中华按蚊,采用WHO推荐的成蚊接触筒法对按蚊进行敏感性测试。结果肥东、肥西和长丰县中华按蚊经0.05%溴氰菊酯测试后,击倒率分别为0、1.96%和4.72%;校正死亡率分别为4.90%、12.23%和20.05%。结论合肥市3县中华按蚊对溴氰菊酯已经产生明显抗性。
Objective To explore the current status of resistance of Anopheles sinensis to deltamethrin in three counties of Hefei city. Methods One village from each of the three counties （Feidong county, Feixi county and Changfeng county） in Hefei city was selected. Pig/ cow- baited traps were used to catch An. sinensis in July and August in 2011. Adult mosquito test kit recommended by WHO was applied for sensitivity test of An. sinensis. Results The knockdown rate of An. sinensis to 0.05% deltamethrin in Feidong, Feixi and Changfeng county was 0, 1.96% and 4.72% respectively. The adjusted mortality rate in the three counties was 4.90%, 12.23% and 20.05% respectively. Conclusion An. sinensis in the three counties of Hefei city have significant resistance to deltamethrin.
