OBJECTIVE: To investigate the effect of the type of neighborhoods on the population structure and dynamics of mosquitoes.
METHODS: The adult population dynamics and larvae breeding of mosquitoes in four different types of neighborhoods were investigated in Yangzhou City.
RESULTS: The number of trapped mosquitoes was the largest in the urban villages, and more than 800 adult mosquitoes were trapped in each urban village, which was significantly higher than that of ordinary and high quality residences. Aedes albopictus and Culex pipiens pallens were dominant species (D > 10%) in the four types of residential areas, and Ae. albopictus was the most dominant species (D > 57%). The peak occurrence of Ae. albopictus in different areas occurred in early June, and it occurred again in the urban village in the middle of September. The occurrence quantity of Cx. pipiens pallens was stable in the ordinary residence and high quality residence, while in the urban village and resettlement residential area, the peak occurred in mid-October. The orders of positive rates, densities and the numbers of mosquitoes in the different types of residential areas were：the urban villages> the resettlement residence> the ordinary residence> the high quality residence. The water vat had the highest positive rate in all kinds of larval habitats, followed by tires and green belt with garbage water.
CONCLUSIONS: The main mosquito species in the four different types of residential areas are all Ae. albopictus and Cx. pipiens pallens, but the positive rate, density and the number of mosquitoes in the different types significantly change, especially in the urban villages, the number and the occurrence peak are significant different from those in the other types of residential areas.
