Abstract:

Objective To investigate the mosquito species, density, and seasonality in Weishan lakes area for local mosquito and diseases control. Methods The surveillance was carried out from April to October in 2014. The adult mosquito density was monitored using carbon dioxide mosquito lamp and mosquito-oviposition trap. While the larval mosquito density was monitored by spoon method for large bodies of water and pipette method for small volumes of water (in containers). Results In total, 10 972 mosquitoes were captured in Weishan lakes area in 2014. The predominant species were Culex pipiens pallens. accounting for 78.45%, followed by Aedes albopictus and C_x. tritaeniorhynchus; Seasonal fluctuations were indicated with one peak in July. The adult mosquito density was the highest in the barn. The positive rate of mosquito larvae was the highest in residential areas. Conclusion The mosquito population was high in Weishan lakes area. The surveillance findings of mosquito density and its seasonal fluctuation can provide guidance for the prevention and control of mosquitoes and mosquito-borne diseases in local area.
