三列伊蚊(Aedes triseriatus)是病毒性脑炎的主要媒介,孳生于树洞和其它小积水容器内。本文介绍在威斯康星州西南部三块相似的小林地(每块大于5ha,主要是栋树)内,分别用双硫磷5G、毒死蜱IG及毒死蜱2E各处理同等数量的容量为200ml的产卵器,药液浓度均为1,125ppm,观察对三列伊蚊雌蚊的驱避和毒杀效能以及对幼虫的杀灭作用。对成蚊的驱避效能:以雌蚊在产卵器中的产卵率和产卵数作为评价指标。通过4周观察,经双硫磷5G、毒死蜱IG处理的和未处
Aedes triseriatus is a major vector for viral encephalitis that breeds in tree holes and other small hydrophytes. This article describes the treatment of an equal number of 200 ml ovipositcs with 5 g of diphtheria, 1 g of chlorpyrifos and 2E of chlorpyrifos in three similar small woodlands (each over 5 ha in each block) in the southwestern Wisconsin. , Liquid concentration of 1,125ppm, to observe the three Aedes mosquito repellent and toxic killing efficacy and killing effect on larvae. Repellent efficacy of adult mosquitoes: Female mosquitoes in the ovipositor spawning rate and number of eggs as the evaluation index. Observed by 4 weeks, treated with 5 g of phoxim, chlorpyrifos IG and not treated
