Abstract: Objective To investigate the species distribution and ecological habit of hematophagous midges in 10 counties or cities in the northeastern and midwestern Jiangxi province, China. Methods Hematophagous midges were captured in 10 counties or cities of Jiangxi (Lichuan, Zixi, Yingtan, Qianshan, Yushan, and Fuliang in the northeast as well as Yongfeng, Xiajiang, Anfu, and Jinggangshan in the midwest) using the light-trap method. The intact individuals of hematophagous midges were selected, and the specimens were slide-mounted in Canada balsam-phenol and subjected to taxonomic identification. Results A total 45 999 hematophagous midges belonging to 27 species in 2 genera were captured in the 10 counties or cities of Jiangxi from June to July, 2018, including 25 species in Culicoides and 2 species in Lasiohelea. Of the 27 species, 11 were recorded for the first time in Jiangxi:C. clavipalpis, C. flaviscutatus, C. innoxius, C. jacobsoni, C. luteolus, C. marginus, C. newsteadi, C. parahumeralis, C. tainanus, C. tenuipalpis, and Lasiohelea diaoluoensis. There were 26 species in the northeastern region and 13 species in the midwestern region. The dominant species were C. arakawai (45.31%) and C. oxystoma (16.71%). The dominant species in the northeastern region were C. arakawai (28.54%) and C. oxystoma (22.05%), and the dominant species in the midwestern region was C. arakawai (91.91%). The species distribution and dominant species varied in different places. The overall blood-sucking rate of 7 dominant species was 16.56%, of which, C. oxystoma had the highest blood-sucking rate (43.90%) and C. arakawai had the lowest blood-sucking rate (6.06%). The total light-trap index of hematophagous midges was 943.54/lamp in six sites, with the highest index in the cattle pen (1 297.78/lamp) and the lowest index in sheepfold (684.25/lamp). The blood-sucking rate and light-trap index varied with different midges species and places. Conclusion The faunal distribution and ecological habit of hematophagous midges in Jiangxi province have been mastered, which provides a reference for investigation as well as prevention and control of midge-borne diseases.

摘要: 目的 调查江西省东北部及中西部10县(市)的吸血蠓种类分布和生态习性。方法 在江西省东北部黎川、资溪、鹰潭、铅山、玉山、浮梁及中西部永丰、峡江、安福、井冈山10县(市)采用诱虫灯诱集吸血蠓类;选择吸血蠓完整个体,采用加拿大树胶酚封片法制作玻片标本,并进行分类鉴定。结果 2018年6-7月在江西省东北部6县(市)和中西部4县(市)采获吸血蠓45 999只,计2属27种,其中库蠓属25种,蠛蠓属2种;江西省首次记录11种,包括棒须库蠓、黄盾库蠓、无害库蠓、连斑库蠓、卢特库蠓、缘斑库蠓、新替库蠓、褐肩库蠓、条带库蠓、细须库蠓和吊罗蠛蠓;东北部6县(市)分布26种,中西部4县(市)分布13种。优势种为荒川库蠓(45.31%)和尖喙库蠓(16.71%);东北部地区优势种为荒川库蠓(28.54%)和尖喙库蠓(22.05%);中西部地区优势种为荒川库蠓(91.91%)。不同场所的吸血蠓种分布和主要种群组成不同。7种主要吸血蠓的总吸血率为16.56%;其中尖喙库蠓最高(43.90%),荒川库蠓最低(6.06%)。6种场所灯诱吸血蠓总指数为943.54只/灯;其中牛舍最高(1 297.78只/灯),羊舍最低(684.25只/灯)。不同蠓种及不同场所的吸血率和灯诱指数不同。结论 掌握了江西省吸血蠓的区系分布和生态习性,为蠓媒疾病研究和防治提供了参考依据。
