摘要: 目的 调查我国东北3省牛舍吸血蠓的种类分布、种类组成、吸血率和灯诱指数。方法 2010-2019年,在东北3省7县(市),采用诱虫灯法在牛舍采集吸血蠓类。采用χ2检验进行吸血率比较。结果 在东北3省7县(市)采获吸血蠓322 505只,计2属29种,其中库蠓属28种,蠛蠓属1种。蠓种分布为宽甸县19种、东宁市15种、逊克县15种、敦化市8种、抚远县8种、清原县6种、集安市7种。优势种为兴安库蠓(38.42%)和刺螫库蠓(37.60%),不同县(市)蠓种类组成不同。4县(市)9种主要蠓种的总吸血率为54.63%,其中东方库蠓最高(71.87%),肩宏库蠓最低(14.68%)。5县(市)灯诱吸血蠓总指数为4 788.98只/(灯·夜),其中敦化市最高〔9 499.94只/(灯·夜)〕,逊克县最低〔1 408.62只/(灯·夜)〕。不同蠓种和不同县(市)的吸血率和灯诱指数不同。结论 东北3省7县(市)牛舍有吸血蠓2属29种,兴安库蠓、刺螫库蠓为优势种,东方库蠓吸血率最高,敦化市灯诱指数最高。

Abstract: Objective To investigate the species distribution, species composition, blood-sucking rate, and light-trap index in the cattle pens in three northeastern provinces of China. Methods From 2010 to 2019, hematophagous midges were captured with light traps from cattle pens in 7 counties (cities) in three northeastern provinces of China. The Chi-square test was used to compare the blood-sucking rates. Results A total of 322 505 hematophagous midges were collected from 7 counties (cities) in northeast China, which belonged to 29 species from 2 genera, including 28 species of Culicoides and 1 species of Lasiohelea. Among them, Kuandian county had 19 species, Dongning city had 15 species, Xunke county had 15 species, Dunhua city had 8 species, Fuyuan county had 8 species, Qingyuan county had 6 species, and Ji'an city had 7 species. The dominant species were C. sinanoensis (38.42%) and C. punctatus (37.60%), and the species composition varied in different counties (cities). The overall blood-sucking rate of 9 main species in 4 counties (cities) was 54.63%. Specifically, C. orientalis had the highest blood-sucking rate (71.87%), and C. humeralis had the lowest (14.68%). The overall light-trap index in 5 counties (cities) was 4 788.98 midges/light·night. Specifically, Dunhua city had the highest light-trap index (9 499.94 midges/light·night), and Xunke county had the lowest (1 408.62 midges/light·night). The blood-sucking rate and light-trap index varied across different midge species and counties (cities). Conclusion There were 29 species from 2 genera of hematophagous midges in the cattle pens of 7 counties (cities) in three northeastern provinces of China. The dominant species were C. sinanoensis and C. punctatus. C. orientalis had the highest blood-sucking rate, and Dunhua city had the highest light-trap index.
