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。 Objective: To observe the effects of catfish (Catfish) on the control of young mosquito pool in urban construction site. Methods: Pond fish stocking. Results: One fry with 10g weight and length of 12cm could feed 1200 IV-instar larvae in one day. One small adult fish weighing 500g preyed on 26,000 larvae in one day. The average density of Culex pipiens pallens before fish culture in experimental area was 465 / scoop, and the rate of adult mosquito bites was 147 / man-hour at night. The density of mosquitoes decreased rapidly after fish culture and mosquito breeding did not occur in 1 week And adult mosquito density decreased by 98.7% and 90.5% respectively. The RPI of mosquito and adult mosquito in fish culture and control areas were 0013 and 0095, respectively. Conclusions: Frying once can control mosquito breeding for a long time.
