目的调查黑龙江省中俄边境口岸蚊种分布及其种群组成。方法采用人帐诱、诱虫灯诱和挥网法采集蚊虫并收集相关文献。结果在黑龙江省中俄边境6个口岸采获蚊虫15 300只,计4属36种,其中长白山亚区(3市县)分布32种,大兴安岭亚区(3市县)分布27种。6个口岸的蚊种分布分别为:饶河28种,黑河21种,萝北20种,漠河20种,绥芬河13种,逊克10种。优势种群是刺扰伊蚊(88.7%)。不同生境、场所的蚊种组成有所不同。刺螫伊蚊是5月的优势种群,刺扰伊蚊是6-9月的优势种群。结论为黑龙江省中俄边境口岸蚊类本底、蚊媒病和防治研究提供了参考。
Objective To investigate the distribution of mosquitoes and the population composition of the border crossings between China and Russia in Heilongjiang Province. Methods Grabs mosquitoes by collecting pet accounts, attracting insects and catching insects, and collecting relevant documents. Results A total of 15 300 mosquitoes were collected from 6 ports of China-Russia border in Heilongjiang Province, accounting for 4 genera and 36 species. There were 32 species in Changbaishan sub-region (3 cities and counties) and 27 species in Daxing’anling sub-region (3 cities and counties). The distribution of mosquito in the six ports were 28 species of Raohe, 21 species of Heihe, 20 species of Luobei, 20 species of Mohe, 13 species of Suifenhe and 10 species of Xunke. The dominant species is Aedes albopictus (88.7%). Different habitats, places mosquito species composition is different. Aedes albopictus is the dominant species in May, and Aedes albopictus is the dominant species in June-September. The conclusion provides a reference for the research on mosquito background, mosquito-borne disease and control in Sino-Russian border crossings in Heilongjiang Province.
