黑龙江流域蚊类调查研究

Investigation of mosquitoes in Heilongjiang River valley

目的调查黑龙江流域蚊类的种类分布和种群组成。方法采用网捕法、人帐诱和诱虫灯诱采集蚊类。结果在黑龙江流域6个市县采获蚊虫70032只，计4属27种，其中大兴安岭亚区（3县）分布26种，长白山亚区（3县）分布23种；6市县的蚊种分布分别为：漠河22种，萝北21种，黑河18种，嘉荫15种，抚远15种，逊克9种。优势种群是刺扰伊蚊（83．7％）。不同生境、场所的蚊种有所差异。5月份的优势种群是刺螫伊蚊，6～9月份的优势种群是刺扰伊蚊。结论为黑龙江流域蚊虫的种类分布和种群组成研究提供了依据。

Objective To investigate the species distribution and community composition of mosquitoes in Hei-longjiang River valley. Methods Insect nets, human - baited net traps and light traps were used to capture mosquitoes. Results A total of 70032 mosquitoes belonging to 4 genera and 27 species are recorded from 6 counties and cities of Heilongjiang River valley ; of which 26 species are distributed in Daxinghnling sub terri-tory （ 3 counties ） ; 23 species are distributed in Changbaishan sub territory （3 counties） ; Species distribu-tion in Mohe, Luobei, Heihe, Jiayin, Fuyuan, Xunke are： 22, 21, 18, 15, 15, 9 respectively. The predom- inant species was Aedes vexans （83.7%） . The comnmnity composition of mosquitoes varied with different habitats and places. Ae. punctor was predominant species in the May, Ae. vexans was predominant species during June to September. Conclusions This study provided the base for species distribution and community composition of mosquitoes in Heilongjiang River valley.
