目的调查济宁市太白湖新区越冬蚊的种类、密度及分布情况。方法于2015年12月至2016年3月,在济宁市太白湖新区选取成蚊监测点采用目测法观察蚊虫数量并记录结果,同时捕捉成蚊在解剖镜下分类鉴定并观察吸血情况。随机选取50%进行解剖,观察蚊虫体内脂肪体累积和卵巢发育情况。结果共捕获成蚊1 677只,均为淡色库蚊。蚊虫越冬以地瓜窖、花房较多,成蚊阳性率分别为98.25%(56/57)和81.36%(48/59)。雌蚊2月下旬体内脂肪体骤减,3月上旬开始出现吸血和卵巢发育,3月中旬体内脂肪开始消失。结论济宁市太白湖新区淡色库蚊以成蚊越冬,主要越冬场所为地瓜窖、花房,应在越冬期加强成蚊的控制工作。
Objective To investigate the species, density and distribution of overwintering mosquito in Taibaihu New Area in Jining. Methods From December 2015 to March 2016, mosquitoes were selected by visual inspection in the Taibaihu New Area, Jining City, and the results were recorded. At the same time, the mosquitoes were caught and identified by dissecting microscope to observe the blood-sucking situation. Randomly selected 50% for anatomy to observe the accumulation of body fat in mosquitoes and ovarian development. Results A total of 1 677 adult mosquitoes were captured, all of which were Culex pipiens pallens. Mosquitoes overwintered to sweet potato cellar, more greenhouse, adult mosquitoes positive rates were 98.25% (56/57) and 81.36% (48/59). Female mosquito body fat body plummeted in late February, beginning in early March vampire and ovarian development, mid-March body fat began to disappear.
