作者于1997年6～10月,在福州城市小区蚊虫主要孳生地放养革胡子鲶鱼苗控制蚊虫孳生,从而减少蚊虫危害程度的研究。实验区主要蚊虫孳生地为排水沟、积水池、发粪池以及缸、罐、废塑料桶、盆景等小型积水。养鱼前重要环境幼虫密度高达856～1213条/勺,室外人饵诱捕叮人率为24.0只/人工小时;室内密度指数为4.5只/间。投放鱼苗后,蚊幼虫密度迅速下降,观察期间主要环境基本未再发现蚊虫孳生,平均室外叮人率下降至3.0只/人工小时;室内密度指数为0.33只/间,与对照区相比较,其相关密度值(RPI)为0.283和0.152,分别下降71.7％和84.8％。在所有放养的水体中,鱼苗生长良好,显示革胡子鲶鱼是城市污染型环境防制蚊虫的良好天敌。
The author from June to October 1997, in Fuzhou city district mosquito breeding places mainly stocking leather catfish seedlings control mosquito breeding, thereby reducing the degree of harm to mosquitoes. The main mosquito breeding areas in the experimental area are drainage ditches, sedimentation tanks, stopes and small tanks of water such as tanks, cans, waste plastic drums and bonsai. The density of important environment larvae before fish farming was as high as 856-1213 / scoop, the rate of outdoor baits was 24.0 / artificial hour, indoor density index was 4.5 / room. After the fish fry were put on, the density of mosquito larvae dropped rapidly. No mosquito was found in the main environment during the observation period, and the average outdoor bite rate dropped to 3.0 / artificial hour. The indoor density index was 0.33 / room, compared with the control area The relative density (RPI) values were 0.283 and 0.152, decreasing 71.7% and 84.8% respectively. In all stocking waters, the fry grew well, indicating that the giant beard catfish is a good natural enemy for controlling mosquitoes in urban-polluted environments.
