目的了解微山湖区不同生境蚊虫密度、种群分布以及季节消长趋势,为指导当地蚊虫综合防制和虫媒传染病防控提供科学依据。方法于2014年4-10月在微山湖区进行监测,成蚊密度监测采用CO2诱蚊灯法;大型水体和小型积水(容器)分别采用勺捕法和吸管法进行幼蚊密度监测;白纹伊蚊专项监测采用诱蚊诱卵器法。结果 2014年4-10月在微山湖区共捕蚊10 972只,其中淡色库蚊占捕蚊总数的78.45%,为优势蚊种;其次为白纹伊蚊和三带喙库蚊;成蚊密度高峰期为7月,幼蚊略早于成蚊;不同生境畜棚蚊密度最高;不同环境幼蚊密度以居民区阳性率最高。结论微山湖区蚊密度较高,不同生境蚊虫种群分布以及密度消长变化趋势可有效指导当地蚊虫防制和蚊媒疾病的科学防控。
Objective To understand the mosquito density, population distribution and seasonal fluctuation in different habitats in Weishan Lake, and provide a scientific basis for the prevention and control of integrated mosquito control and vector-borne diseases. The method was monitored in Weishan Lake from April to October in 2014. The density of adult mosquitoes was monitored by CO2 larva lamp. The density of larvae was monitored by scoop method and pipette method in large water bodies and small hydrops (containers) Aedes albopictus mosquito special monitoring method using the ovitrap. Results There were 10 972 mosquito traps in Weishan Lake from April to October in 2014, of which Culex pipiens pallens accounted for 78.45% of the total number of mosquito traps, which was the dominant mosquito species, followed by Aedes albopictus and Culex tritaeniorhynchus; The peak of density was in July, the juvenile mosquito was slightly earlier than the adult mosquito; the density of mosquitoes in different habitats was the highest; the density of mosquito in different environments was the highest in the residential areas. Conclusion The mosquito density in Weishan Lake is high. The population distribution of mosquitoes in different habitats and the trend of density increase and decrease can effectively guide the local prevention and control of mosquito-borne diseases.
