目的调查山东微山和东平湖区不同生境中传病媒介蚊虫群落分布,为蚊虫防治提供依据。方法在滨湖区的湖泊、稻田、村庄三种蚊虫生境里分别设立监测点,用幼虫勺采集不同水质蚊蚴,半定量法记录其密度;采用人帐诱蚊法通宵捕蚊,分类记录所捕的全年成蚊数量。结果湖泊和稻田均是中华按蚊和三带喙库蚊的主要孳生地,淡色库蚊主要孳生于村庄里的积水;中华按蚊、三带喙库蚊、淡色库蚊在湖泊监测点构成比为24.47%、63.15%、9.00%,在稻田为15.55%、74.82%、9.64%,在村庄为3.25%、13.48%、82.12%。结论滨湖不同生境主要蚊媒种群分布不同;蚊媒防治应采用与生境相适应的措施,才能取得良好的效果。
Objective To investigate the distribution of vector mosquitoes in different habitats in Weishan and Dongpinghu districts of Shandong and to provide basis for mosquito control. Methods The monitoring sites were set up in the habitats of lakes, paddy fields and villages in Binhu District. The larvae scoops were used to collect the mosquitoes with different water quality. The density was recorded by semi-quantitative method. The number of adult mosquitoes caught throughout the year. Results Lake and paddy fields were the main breeding grounds for Anopheles sinensis and Culex tritaeniorhynchus. Culex pipiens pallens mainly breed in the village. Anopheles sinensis, Culex tritaeniorhynchus and Culex pipiens pallens were found in the lake monitoring sites The ratios were 24.47%, 63.15%, 9.00%, 15.55%, 74.82%, 9.64% in paddy fields and 3.25%, 13.48%, 82.12% in villages. Conclusion The distribution of main mosquito vectors in different habitats of lakes and lakes is different. Mosquito control should be adapted to the habitat in order to achieve good results.
