Analysis on mosquito surveillance and ecological characterization in Pingdu city,Shandong province from 2018 to 2021
Objective To understand the characteristics of mosquito species,distribution,density and seasonal fluctuation trend in Pingdu city,Shandong province,so as to provide scientific basis for the prevention and control of mosquitoes and mosquito-borne infectious diseases.Methods From January to December during 2018 and 2021,residential areas,parks,hospitals,farmers and livestock sheds were randomly selected and monitored by mosquito trapping lamp method.And from May to October during 2018 and 2021,3 kinds of habitats,such as residential area,park/bamboo forest,old tire stacking site/scrap station/construction site,were randomly selected to monitor the vector by double-layer stacking method.Re-sults Monitoring results of mosquito trapping lamp method showed that a total of 6 549 female mosquitoes were captured from 2018 to 2021,and the average mosquito density was 1.32 mosquitoes/(lightonight).Culex pipiens pallens was the dominant population(92.44％),followed by Anopheles sinensis(2.26％),Aedes albopictus(0.83％)and Culex tritaeniorhynchus(0.29％).The mosquito density in residential areas,parks,hospitals,houses and livestock sheds was 1.50,1.00,1.44,0.50 and 2.63 mosquitoes/(lightonight),respectively.There was no significant difference in mosquito density among different habitats(H=0.498,P=0.974),but there was significant difference in mosquito species com-position among different habitats(x2=142.092,P=0.000).Monitoring results of double-layer stacking method showed that a total of 319 female mosquitoes were captured from 2018 to 2021,all of them were Aedes albopictus,the average mosquito density was 1.33 mosquitoes/(netohour).The average mosquito density in residential area,park/bamboo forest,old tire stacking site/junkyard/construction site was 1.38,1.50 and 2.00 mosquitoes/(netohour),respective-ly.There was no significant difference in mosquito density a-mong different habitats(H=0.081,P=0.960).Peak adult mosquito densities were concentrated in July-September,with seasonality evident.Conclusion From 2018 to 2021,the dominant mosquito species in Pingdu was Culex pipiens pallens,and the density of mosquitoes showed clear seasonal fluctuations,with the peak of activities occurring between Ju-ly and October for adult mosquito.There is a risk of outbreaks of mosquito-borne infectious diseases such as dengue fever.
