【摘要】：目的了解微山湖区不同生境蚊虫种群分布、密度季节消长以及乙脑病毒携带情况,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。方法成蚊密度监测采用CO2诱蚊灯法;对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 2012-2014年微山湖区共捕蚊32 866只,其中淡色库蚊占捕蚊总数的79.58%,为优势蚊种;其次为白蚊伊蚊(12.51%)和三带喙库蚊(6.13%);季节消长特点为成蚊密度高峰期为7月,幼蚊略早于成蚊;不同生境畜棚蚊密度最高,达11.61只/(灯·h),其次是居民区,为9.36只/(灯·h),湖区湿地和公园绿地密度分别为6.71只/(灯·h)和5.49只/(灯·h),医院蚊密度最低,为4.92只/(灯·h)。采用GLM对不同年度不同生境蚊密度进行分析比较,差异无统计学意义(F=1.294,P0.05);不同环境幼蚊密度以居民区阳性率最高,为4.88%(检查容器5 391处,阳性263处);2012-2014年共采集送检8 962只蚊虫,未检测到乙脑病毒。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。
[Abstract]:Objective to investigate the distribution of mosquito population, seasonal change of density and the carrying of Japanese encephalitis virus in different habitats in Weishan Lake, and to provide scientific basis for guiding the comprehensive control of mosquitoes and the prevention and control of insect-borne infectious diseases. Methods the density of adult mosquito was monitored by CO _ 2 trap lamp, the larval mosquito density was monitored by ladle capture method and suction tube method, and the ovitator method was used in the special monitoring of Aedes albopictus. Results from 2012 to 2014, 32 866 mosquitoes were collected in the Weishan Lake area, among which Culex pipiens pallens accounted for 79.58% of the total number of mosquitoes, accounting for the dominant species, followed by Aedes albopictus (12.51%) and Culex tritaeniformis (6.13%). The density of livestock mosquitoes in different habitats was the highest, with 11.61 mosquitoes per mosquito (light h), followed by residential areas, 9.36) (h), lake wetland and park greenbelt density were 6.71 / (lamp h) and 5.49 respectively) (light h), hospital mosquito density was the lowest at 4.92 / (lamp h). GLM was used to analyze and compare the mosquito density in different habitats in different years. There was no significant difference in mosquito density in different environments (FF1.294, P0.05), and the positive rate of mosquito density in residential areas was the highest, which was 4.88% (inspection containers 5 391, positive 263) and a total of 8 962 mosquitoes were collected and tested from 2012 to 2014. No je virus was detected. Conclusion the density of mosquitoes is high in the area of Weishan Lake. The distribution of mosquito population and the trend of density change in different habitats can effectively guide the local mosquito control and scientific control of mosquito-borne diseases.
