The susceptibility of adult Culex pipiens s.l., Culiseta melanura and Aedes aegypti to insecticide aerosols in wind tunnel exposures varied with time, depending on the stage of blood meal digestion. Greater than 2-fold differences were observed in the concentrations of malathion and synergized resmethrin required to kill test mosquitoes, depending on whether they had been given a blood meal and, if they had, the length of time following the blood meal. The period of lowest susceptibility varied from 24 h after feeding in Ae. aegypti to 72 h in Cs. melanura. The greatest variability occurred during the period when undigested blood was present. Data from tests with a malathion-tolerant strain of Cx. pipiens s.l. suggested little change in susceptibility regardless of blood feeding and the associated weight changes that occur from ingestion of blood.
在风洞暴露试验中，成年致倦库蚊复合组、黑胸库蠓和埃及伊蚊对杀虫剂气雾剂的易感性随时间变化，这取决于血餐消化阶段。根据试验蚊子是否进食血餐以及进食血餐后的时长，观察到杀死试验蚊子所需的马拉硫磷和增效炔丙菊酯浓度存在超过2倍的差异。易感性最低的时期从埃及伊蚊进食后24小时到黑胸库蠓进食后72小时不等。最大的变异性出现在存在未消化血液的时期。对致倦库蚊复合组一个耐马拉硫磷品系的测试数据表明，无论是否进食血餐以及因摄入血液而发生的相关体重变化，易感性几乎没有变化。
