目的调查研究东北三省蚊虫种类和区系分布。方法采用人帐诱、诱虫灯诱、动物诱和网捕采集蚊虫。结果东北三省的蚊类现知6属60种,其中黑龙江省4属40种,35县市有分布;吉林省6属38种,27县市有分布;辽宁省5属36种,50县市有分布。区系分布研究结果表明,东北区分布58种,其中大兴安岭亚区分布25种,长白山亚区分布57种,松辽平原亚区分布38种,蒙新区东部草原亚区分布20种。广布种有6种:中华按蚊、背点伊蚊、刺扰伊蚊、凶小库蚊、淡色库蚊、迷走库蚊。结论为东北三省蚊类的区系分布、媒介种群监测和防治研究提供了科学依据。

Objective To study species and fauna distribution of mosquitoes in three provinces of Northeast China. Methods Using human-baited net trap, light trap, animal-baited trap, and insect net to collect mosquitoes; collecting the data of mosquitoes about species distribution in three provinces of Northeast China. Results There were 60 species and 6 genera mosquitoes in three provinces of Northeast China, of which 40 species and 4 genera in Heilongjiang province,distributed in 35 counties and cities;38 species and 6 genera were known in Jilin province, dis- tributed in 27 counties and cities;36 species and 5 genera in Liaoning Province,distributed in 50 counties and cities. Investigations of fauna distribution showed that 58 species were in Northeastern district, of which 26 species were in Daxinganling subterritoy,57 species in Changbaishan subterrtoy,and 38 species in Songliao-plains subterrtoy. 28 species were in Eastern-grasslands subterrtoy of Mongolia-xingjiang district. The mosquito species of extensive distribution were Anopheles sinensis ,Aedes dorsalis , Ae. vexans , Culex modestus , Cx. pipiens pallens , Cx. vagans. Conclusion The investigation provides the base for further study in three provinces of Northeast China.
