Susceptibility tests were conducted using the World Health Organization diagnostic test procedure on strains of Aedes taeniorhynchus, Aedes sollicitans, Aedes vexans, and Culex nigripalpus collected from several localities in Charleston and Georgetown counties of South Carolina. Aedes taeniorhynchus was resistant to malathion (mortality 1.0-54.4%) but not to propoxur, permethrin, or fenitrothion. There also were indications that Ae. sollicitans and Cx. nigripalpus were resistant to malathion, but to a lesser extent than Ae. taeniorhynchus (mortalities: 72.1-81.0%, and 46.2%, respectively). Aedes vexans was susceptible to malathion (mortality 98.6%). In field tests using ULV application of malathion and field-collected Ae. taeniorhynchus, and susceptible Ae. aegypti and Ae. taeniorhynchus, a noticeably lower mortality also was obtained in the wild mosquitoes.
采用世界卫生组织诊断测试程序，对从南卡罗来纳州查尔斯顿县和乔治敦县几个地点采集的尖音库蚊、骚扰伊蚊、刺扰伊蚊和致倦库蚊菌株进行了药敏试验。尖音库蚊对马拉硫磷具有抗性（死亡率为1.0 - 54.4%），但对残杀威、氯菊酯或杀螟硫磷不具抗性。也有迹象表明，骚扰伊蚊和致倦库蚊对马拉硫磷具有抗性，但程度低于尖音库蚊（死亡率分别为72.1 - 81.0%和46.2%）。刺扰伊蚊对马拉硫磷敏感（死亡率为98.6%）。在使用超低容量喷洒马拉硫磷以及野外采集的尖音库蚊，以及易感埃及伊蚊和尖音库蚊进行的野外试验中，野生蚊子的死亡率也明显较低。
