湖北蚊类分布及地理区划研究

Study on the Delimitation of Zoogeographical Regions in Hubei, on the Basis of Mosquitoes Fauna

目的：探讨湖北蚊类分布及地理区划。方法：借鉴有关蚊类调查资料，结合本省地理概况进行综合分析。结果：已发现蚊类１１属７２种，其中属于东洋界种类的５３种，占７３６％；属于古北界种类的１１种，占１５３％；广布两界种类为８种，占１１１％。结论：经与湖南、江西和河南蚊类分布种比较研究后认为，湖北省蚊类基本应划归东洋界，但北纬３２以北的鄂西北山区划归古北界似较合理。

In the present paper,the writers attempt to deal with the problem of the delimitation of the boundaries of zoogeographical regions in Hubei on the basis of the mosquitoes fauna of the province.Among the 11 genera and 72 species of mosquitoes listed,53 species (or 73.6%) belong to the species entirely or mainly distributed in the oriental region, 11 species (or 15.3%) to those entirely or mainly distributed in the palaearctic region, and 8 species (or 11.1%) to those distributed in both oriental and palaearctic region.Basing on the comparison of the mosquito fauna of the adjacent provinces, including Hunan, Jianxi and Henan, the writers suggests that Hubei province should be included in the oriental region but the North-Western part, lying north of 32 N latitude of the province be included in the palaearctic region.
