Larvae of Aedes hendersoni, Ae. atropalpus, and 6 geographic strains of Ae. triseriatus were compared in terms of their susceptibility to malathion and permethrin. Aedes atropalpus was most tolerant to malathion, whereas Ae. triseriatus (Walton strain) was most tolerant to permethrin. Malathion LC50S for 6 geographic strains of Ae. triseriatus ranked from high to low were: Alabama (ALA) > Michigan (UNDERC) > Indiana (WAL) > Kentucky (UKEN) > Texas (SAL) > Florida (VB); similar ranking of permethrin LC50S resulted in: WAL > VB > SAL > UKEN > UNDERC > ALA. Differences in susceptibility were detected but were not considered large (i.e., over several orders of magnitude). As a result, no change in application rate of malathion or permethrin, from an operational viewpoint, would be warranted if used against these 3 mosquito species or the geographic strains of Ae. triseriatus investigated.
对亨德森伊蚊、阿氏伊蚊以及6个地理品系的三带喙库蚊幼虫对马拉硫磷和氯菊酯的敏感性进行了比较。阿氏伊蚊对马拉硫磷的耐受性最强，而三带喙库蚊（沃尔顿品系）对氯菊酯的耐受性最强。6个地理品系的三带喙库蚊对马拉硫磷的半数致死浓度（LC50）从高到低依次为：阿拉巴马州（ALA）＞密歇根州（UNDERC）＞印第安纳州（WAL）＞肯塔基州（UKEN）＞得克萨斯州（SAL）＞佛罗里达州（VB）；对氯菊酯的半数致死浓度（LC50）的类似排序结果为：WAL＞VB＞SAL＞UKEN＞UNDERC＞ALA。虽检测到敏感性存在差异，但差异不大（即未超过几个数量级）。因此，从操作角度来看，如果针对这3种蚊虫或所研究的三带喙库蚊地理品系使用马拉硫磷或氯菊酯，无需改变其施用率。
