目的了解济宁太白湖湿地蚊虫种类及生态控制策略,为蚊媒的有效防制提供依据。方法用幼虫勺或采集网从太白湖湿地各类孳生地捞取蚊幼虫带回室内进行种类鉴定。采用人饵帐诱捕蚊法和帐扣法,对太白湖湿地的成蚊种类、种群密度、季节消长和夜间活动规律等情况进行调查。结果共捕获成蚊15 332只,经鉴定为5属16种。三带喙库蚊为优势蚊种,占捕获总数的54.40%,其次为淡色库蚊和中华按蚊。各种成蚊的季节变化趋势具有一致性,6月份开始出现,7~8月份为成蚊活动高峰期。成蚊在整个夜间均有活动,黄昏和凌晨出现两次高峰。结论济宁太白湖湿地蚊虫种类丰富。蚊媒防治应结合蚊虫的生态习性采用环境综合治理,方可取得最佳效果。
Objective To understand the species and ecological control strategies of mosquitoes in Taibaihu wetland in Jining, and to provide basis for effective prevention and control of mosquito vectors. Methods larvae scoops or collecting nets were used to collect mosquito larvae from various breeding places of Taibaihu wetland for indoor identification. The artificial bait account was used to trap the mosquito law and the account deduction method to investigate the adult mosquito species, population density, seasonal fluctuation and night-time activity in the Taibaihu wetland. Results A total of 15 332 adult mosquitoes were captured and identified as 5 genera and 16 species. Culex tritaeniorhynchus is dominant mosquito species, accounting for 54.40% of the total catch, followed by Culex pipiens pallens and Anopheles sinensis. The trend of seasonal changes of various adult mosquitoes is consistent, beginning in June and July to August is the peak of adult mosquitoes activity. Adult mosquitoes are active throughout the night, with two peaks at dusk and early morning. Conclusion There are abundant mosquitoes in Taibaihu wetland of Jining. Mosquito control should be combined with the ecological habits of mosquitoes comprehensive management of the environment, in order to obtain the best results.
