目的探明东营地区不同环境蚊类成蚊种群消长规律,为控制蚊类提供科学依据。方法采用国家标准统一规定的CO2紫外线灯诱捕法,在三类不同生态环境开展检测,对不同环境采集到的蚊类进行鉴定分析。结果不同环境不同蚊种有明显的季节高峰,多发生在7-8月份。各蚊种构成比各异,但以淡色库蚊为主,居民区、公园、槐树林淡色库蚊构成比分别占到该环境的81.6%、59.5%和39.8%,差异有统计学意义(P<0.01)。刺扰伊蚊在槐树林中是仅次于淡色库蚊的优势种群之一,构成比为27.0%。白纹伊蚊、三带喙库蚊和中华按蚊在三种环境中也有不同发生,但密度较低。结论不同的生态环境孳生繁衍不同的蚊种,在控制工作中要结合蚊类的生态习性,有针对性的开展防蚊灭蚊工作,预防相应的传染病。 Objective To investigate the growth and decline of adult mosquitoes in different environments in Dongying and to provide a scientific basis for the control of mosquitoes. Methods CO2 UV lamp trapping method was used to determine the mosquitoes collected from different environments in three different ecological environments. Results Different mosquitoes in different environments have obvious seasonal peaks, mostly occurred in July-August. The proportions of the mosquitoes were different, but mainly Culex pipiens pallens, the proportions of residential areas, parks and Culex pipiens pallens were 81.6%, 59.5% and 39.8%, respectively, with significant difference (P <0.01). Aedes albopictus is one of the predominant species in Culex pipiens, second only to Culex pipiens pallens, with a composition ratio of 27.0%. Aedes albopictus, Culex tritaeniorhynchus and Anopheles sinensis also occurred differently in three environments but at lower densities. Conclusion Different ecological environments breed different mosquito species. In the control work, the ecological habits of mosquitoes should be combined with the mosquito control and mosquito breeding work to prevent the corresponding infectious diseases.
