【摘要】：于2011-2013年在海南省的海口市、三亚市、陵水县、昌江县和琼中县等地采用牛诱法捕获中华按蚊。采用WHO推荐的成蚊滤纸接触筒法测定中华按蚊分别接触4%DDT、0.05%溴氰菊酯和5%马拉硫磷等3种杀虫剂的区分剂量60 min内的击倒率,同时设空白对照组。计算半数击倒时间(KT50)和24 h后死亡率,以区分剂量判定抗性级别。死亡率98%~100%为敏感群体(S级),80%~97%为初步抗性群体(M级),80%以下为抗性群体(R级)。结果显示,琼中县中华按蚊对溴氰菊酯的24 h死亡率为95.0%,抗性级别为M,其余地区供试中华按蚊对溴氰菊酯抗性级别为R(死亡率为17.0%~63.0%);海口市、三亚市、陵水县、琼中县和昌江县中华按蚊对DDT的24 h死亡率分别为36.0%、27.0%、24.0%、59.1%和82.0%,抗性级别分别为R、R、R、R和M;海口市、三亚市和陵水县中华按蚊对马拉硫磷的抗性级别为R(死亡率为16.0%~41.0%),而在琼中县和昌江县则为S,死亡率分别为100%和98.0%。
