于1967～1977年在阿肯色州立大学的水稻研究站,进行了二氯苯醚菊酯(permeth-rin)(简称二氯)防治稻田蚊虫的试验。1.实验室灭蚊幼试验将4龄致乏库蚊幼虫和3令、4令野生的骚扰伊蚊和哥伦比亚骚蚊(Psorophoracolumbiae)孑孓分别放入容积为0.24升的纸杯中,每杯10条,测定用水取自稻田灌溉渠中,将算好浓度的“二氯”药液滴入杯中。致乏库蚊测试至少用4种浓度,并各设3个重复;骚扰伊蚊需4种浓度,6个重复,选择4个
In 1967 to 1977 at the Arkansas Rice Research Station, conducted a permethrin (permeth-rin) (referred to as dichloro) to control mosquitoes in rice fields. 1. Laboratory mosquito killing test The 4th instar larvae of Culex pipiens pallens and 3 orders, 4 wild Aedes albopictus and Psorophora columbiae larvae were placed in a 0.24 liter paper cup, 10 per cup , The determination of water taken from the irrigation canal in the rice, will be a good concentration of “dichloro” liquid drops into the cup. Culex pipiens quinquefasciatus test at least four concentrations, and each set of three repeats; harassment Aedes mosquito required four concentrations, six repeats, select four
