目的调查黑龙江省饶河口岸吸血蚊、蠓的种类分布和种群组成。方法采用人帐诱、诱虫灯诱和网捕法采集吸血蚊、蠓,收集相关文献。结果 2008—2009年在饶河口岸采获吸血蚊、蠓90 214只,计6属63种,其中蚊类4属28种;蠓类2属35种,哈尔巴岭库蠓为饶河口岸首次记录的蠓种;优势蚊种为刺扰伊蚊(84.94%);吸血蠓的主要种类是兴安库蠓(37.19%)、不显库蠓(20.03%)和刺螫库蠓(20.04%)。不同生境、场所的主要蚊、蠓种类组成有所不同。结论为黑龙江省饶河口岸吸血蚊、蠓本底、虫媒病和防制研究提供了科学依据。

Objective To investigate the species distribution and population composition of bloodsucking mosquitoes and midges at Raohe port in Heilongjiang province. Methods Bed curtains, light traps and insect nets were used to collect mosquitoes and bloodsucking midges. Results From 2008 to 2009, 90 214 mosquitoes and bloodsucking midges were captured in the region, which belonged to 63 species of 6 genera, 2 families, including 28 species, 4 genera of Culicoidae and 35 species, 2 genera of Ceratopogonidae. Culicoides haerbalingensis were recorded for the first time at Raohe port. The predominant species of mosquitoes was Aedes vaxans （84.94%）. The predominant species of bloodsucking midges were Culicoides sinanoennis （37.19%）, C. obsoletus （20.03%） and C. punctatus （20.04%）. The population composition of mosquitoes and bloodsucking midges varied in different habitats. Conclusion This investigation provided baseline data on bloodsucking mosquitoes and midges for formulation of the prevention and control strategies.
