摘　　要：在室内研究了3种菊酯类药剂对蚊虫的熏倒、灭杀效果。结果表明:当富右旋反式丙烯菊酯浓度为600mg/mL时驱避效果最佳,对志愿者的有效保护时间为7·5h。药剂浓度为200mg/mL时以右旋丙炔菊酯的击倒、灭杀效果最佳,在16h后分别达到了33·3%、20%,当浓度为400mg/mL、600mg/mL时以富右旋反式丙烯菊酯的效果最佳,16h后对蚊虫的击倒、灭杀效果分别达到50%、23·3%和60%、33·3%。混配药剂中,以富右旋反式丙烯菊酯、右旋丙炔菊酯组合剂量均为300mg/mL时最佳,其对志愿者的有效保护时间为6·5h。16h后对蚊虫的击倒和灭杀效果达到了60%和40%。The suffocated, knockdown and killed effects of three Pyrethroid pesticides against mosquitoes have been studied. The results indicate that the protection effect of d-trans allethrin in 600mg/mL is the best, prevented people form bitten for 7.5 hours in single use, while for knockdown and killed effect, the d-prallethrin in dose of 200mg/mL show to be the best, result in 33.3%, 20% control efficacy. As for d-trans allethrin in dose of 400mg/mL and 600mg/mL, the control efficiencies are 50%, 23.3% and 60%, 33.3% respectively after 16 hours. Of blended groups among the three Pyrethroid pesticides, the group blended d- trans allethrin （300mg/mL） with d-prallethrin （300mg/mL） appears to be the best suffocated and killed effect, resulted in 6.5 hours protection period for people, and 60% suffocated and 40% killed effect respectively after 16h.
