作者对于食蚊线虫(Romanomermisculicivorax)能否在污水池内的致乏库蚊幼虫体内寄生和发育,以确定该种线虫是否能防制该种库蚊孳生,在太平洋佛罗里达岛的一个污水处理站内进行了下列实验。实验室试验:取污水池内的污水用去氯的清水稀释成浓度为100、50、25和0%(即100%清水),然后各取200毫升分别置于400毫升玻璃器内,并各放入300条令期为1～6小时的感染期R.c.和25条1～2期的致乏库蚊幼虫,使两者比例为12∶1),置于26C下饲养。7天后每组各取15条4令的致乏库蚊幼虫,在显微镜下检查库蚊幼虫体内有无线
The authors conducted a survey of whether parasitism and development of mosquito-nematode (Romanomermisculicivorax) in Culex pipiens larvae in sewage cells could be monitored in order to determine whether the species could control this Culex pipiens in a sewage treatment station in the Pacific island of Florida The following experiment. Laboratory tests: The sewage in the sewage tank was diluted with dechlorinated water to a concentration of 100, 50, 25 and 0% (ie 100% clear water), and each 200 ml each was placed in a 400 ml glass vessel and placed Into 300 to make a period of 1 to 6 hours of infection Rc and 25 1 to 2 induced Culex pipiens larvae, so that the ratio of 12: 1), placed under 26C feeding. After 7 days, each group took 15 pieces of 4 Culex pipiens larvae, under the microscope check Culex mosquito larvae in vivo with wireless
