球形芽孢杆菌(Bs——10)大面积处理污水坑及下水道,控制蚊幼孳生,在我镇获得成功。奔牛镇属苏南平原水网地区,环境复杂,蚊虫孳生场所多,密度高,上升快,面积大,延续时间长。在早春季节,蚊虫孳生地面积较小,相对集中等特点,为获得农村地区大面积杀灭早春蚊幼现场使用经验,我们于八七年六月选择了南观行政村开展了球形芽孢杆菌处理所有孳生地试验,现将现场杀灭蚊幼效果观察报告如下:
Bacillus sphaericus (Bs - 10) handles a large area of sewage pits and sewers to control mosquito breeding, and succeeded in my town. Benniu town is the southern Jiangsu plain water network area, the environment is complex, mosquito breeding places, high density, fast rise, large area, long duration. In the early spring, mosquito breeding areas were relatively small in size and relatively concentrated. In order to obtain large-scale field experience in early spring mosquito killing in rural areas, we selected Nan Guan Administrative Village to carry out Bacillus sphaericus treatment in June 1987 All breeding ground test, the scene kill mosquito juvenile effect observation report is as follows:
