埃及伊蚊在接触跗部后表现出的DDT中毒症状是兴奋、共济失调、抽搐、全身麻痹和死亡。以前，许多工作人员认为，接触滴滴涕后出现兴奋是致命中毒的证据。这些expts期间的观察。已经证明蚊子在出现初步症状后可能会恢复。亚致死剂量的滴滴涕的兴奋和随后的驱避作用可能是有利的，如在处理过的羊毛上的羊绿头苍蝇变得如此兴奋，以至于它们不能产卵，或不利的，如家蝇和采采蝇，其中根除是必不可少的。在后一种情况下，希望获得快速致死效果并消除排斥性。
The symptoms of DDT poisoning displayed by Aedes aegypti after tarsal contact are excitation, ataxia, convulsions, general paralysis, and death. It was formerly thought by various workers that the appearance of excitation after contact with DDT was evidence of lethal poisoning. Observations during these expts. have shown that mosquitoes may recover after showing the preliminary symptoms. The excitation and consequently repellent effect of sub-lethal doses of DDT may be advantageous, as with sheep blowflies on treated wool becoming so excited they cannot lay eggs, or disadvantageous, as with house and tsetse-flies where eradication is essential. In the latter case it would be desirable to obtain a quick lethal effect and eliminate repellency.
