Abstract:

Objective To identify the mosquito populations and evaluate the control effects in Yuebing village and the surrounding areas of Shahe, Beijing. Methods Mosquitoes were captured using CO₂ light traps and subject to taxonomic identification. Comprehensive control measures based on environmental management and chemical approaches were employed to kill mosquitoes. Results From March to October 2009, 8351 adult mosquitoes were captured, of which Culex pipiens pallens, Anopheles sinensis, Aedes albopictus and Cx. tritaeniorhynchus accounted for 99.57%, 0.19%, 0.18% and 0.06%, respectively. Cx. pipiens pallens was the predominant species. The mosquitoes emerged in early May, peaked in June and July, and generally disappeared by the end of September, mainly dwelling in woods and weeds surrounding the village. However, the mosquito density was relatively low in the village. The comprehensive control measures were simple and effective against mosquitoes. Conclusion The predominant species, seasonal dynamics and geographic distribution of mosquitoes in Yuebing village as well as the potential hazards were basically identified, which was of guiding value for anti-epidemic strategies in large-scale military activities in this region and for mosquito prevention and control in large-scale military assembly.
