Abstract:
Objective To investigate the species,density and distribution of the overwintering adult mosquitoes in Taibaihu District,Jining City. Methods The overwintering adult mosquitoes were monitored by visual observation in Taibaihu District, Jining City from December 2015 to March 2016. The mosquitoes were collected and dissected to observe the body fat accumula?tion and ovarian development situation. Results Totally 1 677 mosquitoes were captured and all of them were Culex pipiens pal?lens. The highest positive rate of overwintering mosquitoes was in sweet potato cellars and greenhouses,with the positive rates of mosquitoes of 98.25%(56/57)and 81.36%(48/59)respectively. The accumulation of the fat body in the female mosquitoes plummeted from late February,and disappeared in middle March. Conclusions The adults of Culex pipiens pallens can over?winter in Taibaihu District,Jining City,and locate in sweet potato cellars and greenhouses mainly. The control work of adult mosquitoes should be strengthened in the overwintering period.
