Investigation and Analysis on Breeding Environment and Disinfection and Sterilization of Mosquitoes in Urban and Rural of Zhangqiu District Jinan City
Objective To analyze the breeding environment and disinfection and sterilization status of mosquitoes in urban and rural areas of Zhangqiu district Jinan city,to provide reference and guidance for the improvement of urban and rural environments.Methods To investigate the mosquito breeding situation in waterlogged areas,communities,and households in Zhangqiu district Jinan city from March 2019 to November 2023,analyze the density of mosquito larvae and mosquito species,and evaluate the effectiveness of mosquito breeding environment management.Results From March 2019 to November 2023,a total of 300 survey points were selected each year,and the positive rates of mosquito larvae were 70%,42%,18%,6%,and 4%,respectively.The positive rates of mosquitoes were 42%,30%,12%,4%,and 2%,respectively.The number of accumulated water and containers for breeding mosquitoes decreased year by year(P<0.05),while the positive rates of mosquito larvae and mosquitoes decreased year by year(P<0.05).From 2019 to 2023,the housing index(HI),container index(CI),and Breitu index(BI)in Zhangqiu district Jinan city were decreased year by year(P<0.05).Between 2019 and 2023,a total of 1 104 mosquito samples were captured,with the main mosquito species including Culex pipiens pallens(43.03%),Aedes albopictus(26.00%),Culex tritaeniorhynchus(11.96%),and Anopheles sinensis(8.97%).Conclusion The management of mosquito breeding in the urban and rural of Zhangqiu district Jinan city has achieved remarkable results,and the mosquito breeding situation is improved.It is necessary to focus on disinfection and sterilization the dominant mosquito species,such as Culex pipiens pallens,Aedes albopictus,Culex tritaeniorhynchus,Anopheles sinensis,to lay the foundation for the control of mosquito borne diseases.
