摘要
目的 调查和分析骚扰阿蚊幼虫在不同生境积水中的孳生情况 ,了解其孳生习性及其影响因素。方法 选择取样点 ,用塑料勺捞取的蚊幼虫 ,计算其密度 ,将部分蚊幼虫带回实验室待羽化后鉴定蚊种 ,并记录调查点的环境因素。结果 搔扰阿蚊的孳生地非常广泛 ,孳生密度以人粪尿池、污水沟最高 ,排水沟、盛污水的容器次之 ,其他积水点相对较低。骚扰阿蚊幼虫多以共生形式生存 ,较适宜孳生的水温是 (2 5± 4 )℃ ,pH值在 6 8～ 7 4之间。结论 应及时消除骚扰阿蚊的孳生地 ,以减少其孳生密度。
Objective To investigate the breeding habits and influence factors of the Armigeres subbalbeatus in different collected water. Methods Counting the larvae density of the Armigeres subbalbeatus in different mosquito breeding sites and recording the environmental factors. Results The breeding sites of the Armigeres subbalbeatus were wide-ranging.The breeding density was maximum in manure pits and domestic sewage.It took second place in drain and collected water container,and it was minimum in other waterbeachs.The larvae of the Armigeres subbalbeatus was fit to be bred in the water of (25±4) ℃ ,and pH was from 6.8 to 7.4. Conclusion It was necessary to eliminate the breeding sites of the Armigeres subbalbeatus,so its breeding density would be reduced.
