韶关市区2006～2011年蚊密度监测结果分析

目的 了解韶关市区成蚊密度及其季节消长规律,为制订和调整防制对策提供科学依据.方法 蚊密度监测采用诱蚊灯法.结果 2006～2011年共布诱蚊灯1072盏,捕获成蚊12081只,平均密度为11.27只/灯.密度高峰出现在第二季度,5月份左右出现最高峰,密度为29.32只/灯.成蚊各月份均可捕获,致倦库蚊为优势种群,占85.6％.不同场所蚊密度为公园＞农村户＞医院＞居民区.结论 韶关市区蚊种群密度特征和季节消长规律揭示了近年来环境干预的良好效果,建议今后仍要持之以恒地加强蚊密度消长高峰前的控制,以及开展以环境治理为主的综合防制措施.

Analysis of monitoring results of adult mosquito density in Shaoguan downtown area from 2006 to 2011

Objective To understand the adult mosquito density of Shaoguan downtown area and to provide scientific basis for establishing or adjusting control and prevention measures. Methods The mosquito trap lamps were used to monitor the density of adult mosquitoes in Shaoguan city from 2006 to 2011. Results A total of 12 081 mosquitoes were captured from 2006 to 2011, with the average mosquito density of 11.27 per lamp. The density peak of mosquitoes appeared at the second quarter, and the highest is 29.32 per lamp in May. The adult mosquitoes were captured for every month of the year, and Culex quinquefasciatus was the dominant specie. Different habitats in descending order of the mosquito density were parks, rural areas, hospitals and residential areas. Conclusion The characteristics of the mosquito population density and the seasonal fluctuations therein could reflect the environmental controlling effect well. It is necessary to strengthen mosquito control during the high density months, and adopt environment-centered integrated measures consistently.
