摘要: 目的探索在广州市城区采用高效氯氰菊酯进行现场超低容量喷雾,杀灭室外白纹伊蚊成蚊的合适喷药量。方法在实验室、现场分别进行高效氯氰菊酯超低容量喷雾,观察对敏感白纹伊蚊及广州市城区白纹伊蚊成蚊的杀灭效果。结果在实验室测得高效氯氰菊酯当喷药量为0.4ai·mg/m2时,对广州市城区白纹伊蚊成蚊的致死率为96.0%;在现场测得当喷药量为0.5ai·mg/m2时,距喷药点5、10、15m,对靶虫的杀灭率分别为100%、96.0%、75.0%。结论采用高效氯氰菊酯以0.5ai·mg/m2的药量进行超低容量喷雾,在有效喷幅范围内对白纹伊蚊有良好的控制效果。

Abstract: Objective To explore the dosage of beta cypermethrin against Aedes albopictus by ultra low volume(ULV) spraying in Guangzhou City.Methods Adult mortality of Aedes albopictus,sensitive and field population collected from Guangzhou,was observed after ground ULV exposured to beta cypermethrin in laboratory and in field.Results The beta cypermethrin was applied at 0.5 ai·mg/m2 in the field resulted in 100% control of the field population 5 m from the point of application,control decreased to 96.0% at 10 m,and to 75% at 15 m.Conclusion The study showed that Aedes albopictus collected in Guangzhou was controlled by ground ULV exposured to beta cypermethrin at the dosage of 0.5 ai·mg/m2.
