Objective To understand the mosquito species composition,population density,and seasonal fluctuation in Lianyungang City from 2018 to 2022,and to provide technical support for integrated control of mosquito-borne diseases in Lianyungang.Methods Light-trap method was employed to investigate adult mosquitoes in 100 monitoring points in 5different habitats of urban residential areas,parks,hospitals,rural houses and livestock sheds in Lianyungang from March to November,and the mosquito population density,species composition indifferent habitats,and seasonal fluctuation were analyzed.Results A total of 91 731 adult mosquitoes were captured in Lianyungang City from 2018 to 2022,and the overall mosquito density was 1.77 mosquitoes/(lamp·h).Culex pipiens pallenshad the highest proportion,accounting for 55.69%.Mosquito activity peaked in August,and the highest mosquito density was found in livestock sheds,as much as 4.61 mosquitoes/(lamp·h).There was a statistical difference in the composition of mosquito species between different habitats(P＜0.05).The mosquito density in urban areas,rural areas,and the whole city in Lianyungang generally decreased,and the difference of decline trend had statistical significance(P＜0.05).Conclusion Culex pipiens pallens had the highest constituent ratio in Lianyungang.The mosquito density in urban and rural areas in Lianyungang generally decreased and was highest in livestock sheds.However,mosquito control in livestock sheds should be strengthened.It is suggested that comprehensive mosquito prevention and control measures should be carried out before and after the peak period.
