摘要
河西走廊地处青藏高原和内蒙古高原的过渡地带,是甘肃省的粮棉基地。河西走廊的昆虫分布,前人已做过一些调查、采集以及分析工作,发表过一些见解。作者现根据在河西走廊采集、鉴定的昆虫标本和该区植保部门提供的农业昆虫名录,取其中分布资料比较完整的491种,并参考当地的地势地形、气候状况、植被和农业昆虫的发生特点,对河西走廊农业昆虫的区系结构和生态分布进行了分析,籍此可以比较清楚地看出该区农业昆虫的区系结构概貌。
Faunal analysis was made for 491 species of agricultural insects, including pests and their natural enemies, which were collected in Hexi Corridor of Gansu province. The fauna of insects appeared to be intermixture between those of Northeast subregion and Mid-Asia subregion. The author suggested that Hexi Corridor could be divided into two divisions: the east and the west Hexi Corridor divisions. Dominant groups of agricultural insects and their ecological distribution in each division were discussed in the paper.
