目的了解山东北湖地区蚊虫种类及生态习性,为蚊媒的有效防制提供依据。方法于2014-06/10用幼虫勺或采集网从北湖区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,对北湖地区的成蚊种类、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10 836只,经鉴定为6属17种。淡色库蚊为优势蚊种,占捕获总数的69.48%,其次为三带喙库蚊和中华按蚊。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2次高峰。结论山东省北湖地区蚊媒孳生地众多,蚊虫种类繁多。蚊媒的有效防治应结合蚊虫的生态习性及自然情况,方可取得最佳效果。
Objective To understand the species and ecological habits of mosquitoes in the Beihu area of Shandong Province and provide the basis for effective prevention and control of mosquito vectors. Methods The larvae scoops or collection nets were used to collect mosquito larvae from various breeding places in Beihu district for identification of species. The artificial bait account was used to capture the mosquito law and the account deduction method to investigate the adult mosquito species, population density, seasonal fluctuation and the law of night activities in the North Lake. Results A total of 10 836 adult mosquitoes were captured and identified as 6 genera and 17 species. Culex pipiens pallens dominant mosquito species, accounting for 69.48% of the total capture, followed by Culex tritaeniorhynchus and Anopheles sinensis. The trends of seasonal changes of various adult mosquitoes are consistent, beginning in June and July-August being the peak of adult mosquitoes activity. Adult mosquitoes are active throughout the night, with 2 peaks at dusk and early morning. Conclusion There are many mosquito breeding places in the Beihu area of Shandong Province with a wide range of mosquitoes. Effective mosquito control should be combined with the ecological habits of mosquitoes and the natural situation, in order to obtain the best results.
