Abstract：Objective To investigate the species distribution,species composition and blood-sucking rate of hematophagous midges in 4 cities of Jilin Province and Liaoning Province.Methods The hematophagous midges were captured with light traps from cattle pens and sheep pens in Benxi,Fengcheng,Liaoning Province and Shulan,Tonghua,Jilin Province.The blood-sucking rate of midges among different midges species and different places were compared using x2 test.Results From July to August 2024,a total of 57 492 hematophagous midges were collected from 4 cities in Liaoning and Jilin Provinces,and 15 species of Culicoides were identified.There were 9 species distributed in Benxi,8 species in Fengcheng,8 species in Shulan,and 12 species in Tonghua.The total proportion of C.punctatus in two provinces and four cities was the highest(54.20％);the dominant species of the four cities were C.tainanus(91.24％)in Benxi,C.tainanus(66.77％)in Fengcheng,C.punctatus(85.10％)in Shulan,and C.sinanoensis(46.54％)in Tonghua,the composition of main species of hematophagous midges were different in different places.The overall blood-sucking rate of 4 dominant species was 62.38％,of which,C.tainanus had the highest blood-sucking rate(62.59％),and C.sinanoensis had the lowest blood-sucking rate(61.30％).The blood-sucking rate of the main species of midge was different in different places.C.matsuzawai and C.tainanus were recorded for the first time in Jilin Province.Conclusion There were 15 species of hematophagous midges were collected from 4 cities of Liaoning Province and Jilin Province(2 species were recorded for the first time in Jilin Province),the dominant species was C.punctatus,the blood-sucking rate of C.tainanus was higher.At the same time,the distribution of hematophagous midges in the four cities have basically figured out,which provides a reference for the study on the fauna,ecology,control and disease relationship of hematophagous midges in Jilin Province and Liaoning Province.
