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 investigate the species and ecological Province and provide reference for controlling mosquitoes and Methods From June to October 2014, mosquito larvae were habits of mosquitoes in Beihu Region of Shandong preventing mosquito -borne diseases in the area. collected from various breeding sites in Beihu Region using larva scoops or nets, and the species were identified in laboratories. Adult mosquitoes were captured by manbait net trap method and mosquito net method, and the species, population density, seasonal fluctuations and night blood - sucking activities were investigated. Results A total of 10 836 mosquitoes were collected from all the surveyed sites and assigned to 17 species and 6 genera. Culex pipiens palllen was dominant in the area, accounting for 68.96%, followed by Culex tritaeniorhynchus and Anopheles sinensis. The seasonal fluctuations of all the adult species were consistent, with appearance beginning in June and the activities peaking in July and August. The blood - sucking activity of mosquitoes lasted over the night, with two peaks at sunset and daybreak respectively. Conclusion There are lots of mosquito breeding sites and various mosquitoes in Beihu Region of Shandong Province. The mosquito control measures should be based on the mosquito ecological habits and obtain the optimal results. the natural conditions so as to
