The hyperactivity, incoordination, recovery, and mortality produced by four alpha-cyanopyrethroids usually used for Chagas disease vector control (beta-cypermethrin, beta-cyfluthrin, lambda-cyhalothrin, and deltamethrin) were evaluated on third instar nymphs of Rhodnius prolixus. All pyrethroids modified the locomotor activity of the nymphs, which increased linearly as a function of the log of insecticide concentration. lambda-Cyhalothrin showed the lowest values of Effective Concentration 50%, Lethal Concentration 50%, Effective Time 50%, and Lethal Time 50% when insecticides were applied by contact with treated filter papers. Recovery from incoordination was observed after topical application of the insecticides. The recovery was inhibited by the simultaneous application of piperonyl butoxide, suggesting that biotransformation by mixed-function microsomal oxidases is involved in the process of recovery.
对通常用于控制恰加斯病病媒的四种α-氰基拟除虫菊酯（高效氯氟氰菊酯、联苯菊酯、氯氟氰菊酯和溴氰菊酯）对红带锥蝽三龄若虫产生的多动、不协调、恢复情况及死亡率进行了评估。所有拟除虫菊酯均改变了若虫的运动活性，其随杀虫剂浓度对数呈线性增加。当通过与处理过的滤纸接触施用杀虫剂时，氯氟氰菊酯的半数有效浓度、半数致死浓度、半数有效时间和半数致死时间值最低。经局部施用杀虫剂后观察到不协调症状的恢复。胡椒基丁醚同时施用会抑制恢复，这表明混合功能微粒体氧化酶的生物转化参与了恢复过程。
