1992年8～9月,我们在北京西局养猪场,联合应用灭幼宝与诺毕速灭松杀灭蚊、蝇,取得较好效果。在发生季节高峰,成蝇平均密度由167只/0.5h降至10只/0.5h,密度下降率达94%以上;1周后第2次喷药,下降率达99.2%;1个月内蝇幼平均密度保持在0.22条/g以下,密度下降率保持在96.17%以上;施药后2个月化蛹变小、变畸,羽化率明显降低,在6.54%以下。现场投施灭幼宝对淡色库蚊有明显的速杀力,投药后3天幼虫密度下降率达100%,1周后回升;再次投药后3天,密度下降率又达98.78%。
From August to September 1992, we worked at the pig breeding farms in Beijing West Bureau of Beijing to jointly kill and kill mosquitoes and flies with Kilo and Novo Biotech, achieving good results. At the peak of the season, the average density of adult flies decreased from 167 / 0.5h to 10 / 0.5h and the density decreased more than 94%. After 1 week, the second spraying rate was 99.2%; within 1 month The average density of young flies maintained at below 0.22 / g, the rate of density decline remained above 96.17%; pupae became smaller and deformed after 2 months of application, and the rate of emergence was significantly lower at 6.54%. On-the-spot application of the offspring showed obvious killing power against Culex pipiens pallens. The density of the larvae decreased 100% after 3 days of administration and recovered after 1 week. The density decreased 98.78% after 3 days of re-administration.
