摘要: 拟除虫菊酯杀虫剂广泛应用于蚊香及其他驱蚊产品,不仅对蚊子有杀虫作用,而且具有驱避效应,然而拟除虫菊酯杀虫剂对蚊子驱避作用的机理尚不清楚。本研究发现两种挥发性拟除虫菊酯杀虫剂四氟甲醚菊酯和氯氟醚菊酯对白纹伊蚊和埃及伊蚊具有非接触驱避作用。触角电位(EAG)试验表明除四氟甲醚菊酯有微弱EAG响应外,其他拟除虫菊酯杀虫剂均没有EAG响应。此外,发现四氟甲醚菊酯和氯氟醚菊酯对携带kdr突变的抗性埃及伊蚊品系的驱避作用明显低于敏感品系。研究表明,拟除虫菊酯杀虫剂对蚊子的非接触驱避效应并非通过嗅觉系统介导,有可能是通过其他途径起作用,如钠离子通道。

Abstract: Pyrethroids, with both insecticidal and repellent activities, have been widely used in mosquito coils and other mosquito-repellent products. However, the repellent mechanism of pyrethroid remains unknown. In this study, two volatile pyrethroids, dimefluthrin and meperfluthrin, induced spatial (non-contact) repellency in Aedes aegypti and Aedes albopictus in a hand-in-cage assay. Electroantennography (EAG) recordings showed that, except dimefluthrin, other pyrethroids did not elicit EAG responses from adult antennae. Furthermore, the repellency of dimefluthrin and meperfluthrin was weaker against pyrethroid-resistant population of Aedes aegypti (Puerto Rican) carrying kdr mutations on sodium channels than against the susceptible population. Our results suggest that activation of olfactory system is not responsible for pyrethroid repellency in mosquitoes, maybe other factors, such as sodium channels, contribute to pyrethroid repellency.
