This paper reports the investigation of the occurrence and physiological age composition of Culex tritaeniorhynchus overwinter from February to May 1987 and from February to April 1988 in Wuxi, Jiangsu and Yangzhou in Shanghai and Shanghai Fengxian. The mosquito in Wuxi, Shanghai in March, increased significantly in mid-April. February When temperatures are above 11 ° C, individual mosquitoes can be trapped in barns. Larvae appeared in late April, and new mosquitoes appeared in late April and early May. Yangzhou catch the mosquito time than Wuxi, Shanghai about a month later. Early mosquitoes were not laid eggs, fertilization rate was 98%; wing scales and thoracic bone test showed that the mosquito as an old mosquito, development of mosquitoes accounted for 94% of the performance of mosquitoes reproductive nutrition coordination. Carbon dioxide early mosquito trapping effect is not obvious.
