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1 072盏,捕获成蚊12 081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。
Objective To understand the density and seasonal fluctuation of adult mosquitoes in Shaoguan City and provide a scientific basis for formulating and adjusting prevention and control measures. Methods mosquito density monitoring method using mosquito lamp. Results A total of 1 072 mosquito lamps were collected from 2006 to 2011, and 12 081 mosquitoes were captured with an average density of 11.27 / lamp. The peak of density appears in the second quarter, with the highest peak around May with a density of 29.32 lights / lamp. Adult mosquitoes can be caught in each month, Culex pipiens quinquefasciatus is the dominant species, accounting for 85.6%. Mosquito density in different places for the park> rural households> hospitals> residential areas. Conclusion The mosquito population density characteristics and seasonal fluctuation patterns in Shaoguan City reveal the good effect of environmental intervention in recent years. It is suggested that the control before the peak of the mosquito density increase should be persistently strengthened in the future and the comprehensive prevention and control measures based on environmental management should be carried out.
