可膨胀塑料珠浮于水面,对库蚊的幼虫、蛹及雌蚊产卵构成屏障,可有效控制厕所化粪池内库蚊的孳生。在桑给巴尔岛的一些村庄,此方法已成功地控制了由致倦库蚊传播的丝虫病。为观察塑料珠对露天污水中库蚊孳生的控制效果,作者在坦桑尼亚Ifakara的St.Francis地区一所医院内进行了实验。
Inflatable plastic beads floating on the surface of the larvae, pupae and female mosquito larvae constitute a barrier to oviposition, which can effectively control toilet septic tank Cuckoo breeding. In some villages in Zanzibar, this method has succeeded in controlling filariasis transmitted by Culex quinquefasciatus. To examine the control effect of plastic beads on the growth of Culex pipiens in open-air sewage, the authors conducted an experiment in a hospital in St. Francis, Ifakara, Tanzania.
