Abstract:
Objective To evaluate Aedes albopictus infestation status in the central urban area of Shanghai,and analyze the related epidemic risk of mosquito-borne infectious disease.Methods Consecutive mosquito surveillance was conducted in the green lands and residential areas in the central urban area of Shanghai during 2012-2014,the Aedes albopictas density and its seasonal fluctuation were observed;the sequence ofAedes albopictus in Shanghai was aligned with that in other epidemic area abroad,and the susceptibility ofAedes albopictus to mosquito-borne virus and endemic risk were analyzed.Results No Aedes aegypti was found in the central urban area of Shanghai.As predominant species in both the residential area and the green lands,the proportion ofAedes albopictus in the residential area was significantly higher than that in the green lands (78.53％ vs.19.99％,x2=15 525.168,P＜0.001),and so was the density (11.91,42.02 pcs/day· site in the residential area vs.3.65,2.18,2.73 pcs/day· site in the green lands,all P value＜0.001).In 2014,the density reached 42.02 pcs/day · site and the proportion reached 94.69％ in the residential areas.Phylogenetic tree analysis showed that the genetic distance between Aedes albopictus in Shanghai and Aedes albopictus in Africa was quite far.Conclusion No Aedes aegypti was found in Shanghai and its surrounding areas,while Aedes albopictus infestation in the central urban area of Shanghai was serious.Strict measures should be taken to reduce the Aedes albopictus density for the effective control Zika virus spread.
