摘要: 目的:观察革胡子鲶鱼防制城市建设工地积水池蚊幼的效果。方法:积水池中放养鱼苗。结果:1条10g重、长约12cm的鱼苗,1天可捕食Ⅳ龄幼虫1200条;1条500g重的小成鱼,1天至少捕食蚊幼26000条。实验区养鱼前致倦库蚊幼虫密度平均为465条/勺,成蚊夜间叮人率为147只/人工小时;养鱼后蚊虫密度迅速下降,1周后再未发现蚊虫滋生,蚊幼与成蚊密度分别下降98.7%和90.5%;养鱼区、对照区蚊幼与成蚊RPI值分别为0.013和0.095。结论:1次投放鱼苗可长期控制蚊虫滋生。

Abstract: During recent years, the investigation revealed that the pool amounts at constructing sites were significantly breeding in urban area.The paper reported a result of the mosquito control with Clarias fuscus wich was introduced from Egypt in 1994-1995.A fish about 10g or 12cm long can catch 1200 larvae of Culex pipiens quinquefasciatus;a fish of 500g can catch 26000 larvae at least for one day Before putting in the fish, the average larvae density was 465 worms/spoon (350ml), the biting rat was 147 times/m.h in night at the trial area where there were 37 pools about 2000m2 at a underground constructingsite.Since putting in Clarias fuscus, the densities of larvae and adults were descended quickly and the pools wer not found with mosquito breeding after a week.The average biting rat was 16/m.h at the area where no constructing sites.RPI were 0.013 and 0.095 in the area of trial and contrast.The result shown the densities of larvae and adult mosquitoes was descended 98.7% and 90.5% respectively.Claria fuscus were growing well in the breeding sits and can survive in winter in Fuzhou.The result showed the fish is a good natural enemy to mosquito.
