我市系国际开放港口,外轮来往频繁,为防上登革热传入,控制蚊媒埃及伊蚊孳生地是主要措施。在北海市郊,埃及伊蚊主要孳生地为室内饮用水缸,缸内不能投放药物,人工管理(如经常换水、洗刷水缸等)推广也有困难。因此,有必要试用生物消灭伊蚊幼虫。国内外曾利用食蚊鱼(Gambusiasffinis)吞食蚊幼虫效果较好。但食蚊鱼喜于水面游动,饮用水缸放养后,群众用水不方便。所以我们选用喜沉水底、捕食水生
Our city is an international open port with frequent rounds of external traffic. In order to prevent the introduction of dengue fever, mosquito control mosquito Aedes aegypti mosquito breeding ground is the main measure. In the suburb of Beihai, the main breeding place for Aedes aegypti is indoor drinking water tank, which can not be put into the tank. Manual management (such as frequent water change, scrubbing water tank, etc.) is also difficult to popularize. Therefore, it is necessary to try out the creatures to eliminate the mosquito larvae.
