Abstract:
Objective To understand the species composition, density and seasonal variation of adult mosquitoes in Tongliao City of Inner Mongolia Autonmous Region from 2017 to 2019, and to provide scientific data for risk assessment and prediction of mosquito-borne diseases, mosquito-borne control planning, precise implementation and effect evaluation. Methods The density of adult mosquitoes was monitored in parks, hospitals, residential areas, farmers and cattle sheds in Tongliao by using the light trap method. Results A total of 3 358 adult mosquitoes were captured, including Anopheles sinensis, Culex tritaeniorhynchus and Culex quinquefasciatus with Culex quinquefasciatus as the dominant species.The change curve of adult mosquito density with season showed a single peak, and the peak period was from July to September.The density of adult mosquito in cattle shed was the highest (6.71 per night), and that in hospital was the lowest (0.99 per night).The difference between urban and rural areas in seasonal distribution of adult mosquitoes was statistically significant (χ2=4.65, P < 0.05). Conclusion Culex pipiensquinquefasciatus is the dominant mosquito species in the local area, and the villages are the places with high incidence of mosquito infestation.
