目的掌握镇江口岸蚊类的种群和季节消长情况,为开展口岸蚊类防治工作提供科学依据。方法采用人帐诱捕法,定点、定人、定时在3个不同生态环境点上进行诱捕。结果共捕获成蚊621只,密度为8.63只/(帐.人工小时),蚊虫经鉴定为4属8种,其中淡色库蚊为优势蚊种。镇江口岸3月下旬开始出现蚊虫,6月份达到最高峰,9月份以后密度下降,12月底蚊虫消失。结论随着长江口岸不断开发利用,生态环境正在变化,蚊类种群、密度和季节消长将随之变化,应加强蚊类的监测和控制,尤其是加强对外来蚊种和新发现蚊种的监测和控制。
Objective To grasp the population and seasonal fluctuation of mosquitoes in Zhenjiang Port and provide a scientific basis for the prevention and control of mosquitoes at ports. Methods Trap method, fixed-point, fixed-person, regular trapped in three different ecological environment points. Results A total of 621 adult mosquitoes were collected, with a density of 8.63 / (artificial human hour). Mosquitoes were identified as 4 genera and 8 species, of which Culex pipiens pallens were dominant mosquito species. Mosquitoes began to emerge in late March in Zhenjiang Port and reached the peak in June, with the density dropping after September and disappearing by the end of December. Conclusions As the Yangtze River Estuary continues to develop and utilize, the ecological environment is changing, the mosquito population, density and seasonal fluctuation will change accordingly. Monitoring and control of mosquitoes should be strengthened, especially monitoring of exotic mosquito species and newly discovered mosquito species And control.
