鄂西南三个自然保护区蚁科昆虫的区系调查

星斗山自然保护区、木林子自然保护区和坪坝营自然保护区地处湖北省西南山区,地形地貌复杂,属大陆性中亚热带季风湿润气候,昆虫资源十分丰富,作者首次报道这3个自然保护区蚂蚁的种类和分布。结果表明3个自然保护区共有蚂蚁53种,隶属于5亚科,22属。在区系组成上,东洋界种类25种,占全部种类的47.1%,东洋界和古北界均有分布的种类22种,占41.5%,古北种和特有种各有3种,分别占5.6%。说明3个自然保护区的蚂蚁以东洋界为主。并分析了3个自然保护区蚂蚁的分布特征。

Fauna of Formicidae ants from three nature reserves in southwest Hubei

Xingdoushan Nature Reserve, Mulinzi Nature Reserve and Pingbaying Nature Reserve are located in a mountainous area of southwest Hubei, with varied topography and landforms, humid monsoon climate of continental central subtropics and high insect diversity. However, no survey on the fauna and taxonomy of the ant in this region has been undertook before. In this paper, the checklist and distribution of the ants in three nature reserves were reported. There are 53 species belonging to 5 sub_families, 22 genera in these nature reserves. Among them, 25 species are the Oriental species, accounting for 47.1% , 22 is common species to the Oriental and the Palaearctic Regions accounting for 41.5%, 3 the Palaearctic species, and 3 the endemic species (3) accounting for 5.6% respectively. The result shows the Oriental species take great part in the ant fauna of these nature reserves. In addition, the distribution characteristics of the ant in these nature reserves are analyzed.
