Abstract:
In order to investigate the density, distribution and seasonal dynamics of mosquito populations in Yongxing Island of Sansha City, mosquitoes were collected with methods of mosquito-lured lamp and artificial biting in four kinds of mosquito-habitats from April 2016 to March 2017. A total of 2 030 adult mosquitoes were collected, belonging to 5 species. The Culex quinquefasciatus population were dominant in number. There was statistical significance in the composition ratio of mosquitoes in different habitats by χ2 test. The seasonal growth curves were bimodal type. The annual two density peaks always exist, one from May to June and the other from August to September. Among them, the monitoring density in the annul and the lowest density existing in December (5.58/person·hour). Risk assessment showed that mosquito bites, the risk of harassment would be extremely high risk, and the risk of epidemic encephalitis, yellow fever, chikungunya fever, Zika virus disease, dengue fever and dengue hemorrhagic fever is moderate risk. The annual mosquito density in Yongxing Island of Sansha City is at a relatively high level. Monitoring should be strengthened to prevent the colonization and spread of foreign mosquito-borne diseases in Yongxing Island, Sansha City.
