An analysis of fly ecological surveillance results in Hebei Province,China,2011-2023
Objective To investigate the species composition,density,habitat distribution,and seasonal fluctuations of fly in Hebei Province,China,so as to provide a scientific basis for fly control in Hebei Province.Methods From April to November in 2011 to 2023,fly density was monitored using cage traps with sugar-vinegar baits at four types of habitats (farmers' markets,catering surroundings,green belts,and residential areas) in the fly surveillance areas of 17 cities and counties.WPS Excel 11.1.0.11045 and R 4.2.2 softwares were used to process the data.The species composition of fly was analyzed and fly density and fluctuations between different species were compared in different years,months,habitats and regions by using the Chi-square test,t-test,analysis of variance,Kruskal-Wallis H test,and Friedman test.Results From 2011 to 2023,a total of 9349 cages were placed in Hebei Province,trapping a total of 42647 flies,with an average density of 4.56 flies/cage.The dominant populations were Musca domestica,Muscina stabulans,Sarcophagidae flies,and Lucilia sericata,accounting for 52.91％,13.46％,9.26％,and 5.54％ of the total catches,respectively.In 2019-2023,the total density of flies in Hebei Province showed a downward trend.Fly total density showed a single peak in August at a density of 7.25 flies/cage,and the unimodal pattern occurred in all habitats,with peaks in July to August.Among the four types of habitats,the density of flies in farmers' markets was highest,reaching 6.13 flies/cage,followed by residential areas,green belts,and catering surroundings,showing a significant difference in fly density between different habitats (Q=26.012,P<0.001).Fly density was highest in farmers' markets from 2011 to 2020 and highest in green belts from 2021 to 2023,with a significant difference in annual density fluctuation between different habitats (F=15.541,P<0.001).The average fly density in southern Hebei was 5.88 flies/cage,while that in the northern region was 3.98 flies/cage,which were significantly different (t=-3.055,P=0.009).Conclusions The focus of fly control in Hebei Province should be on Musca domestica,Muscina stabulans,Sarcophagidae flies,and L.sericata and in farmers' markets.In recent years,the density of flies in green belts has increased.The peak period of fly activity is from July to August.The control measures should be taken before the peak period according to the law of fly activity in different regions of Hebei Province.
