中国侧棘斑蚜属(蚜科,角斑蚜亚科)地理分布格局研究

用GIs技术研究斑蚜科侧棘斑蚜属Tuberculatus在中国的地理分布格局。种类以县级行政单元转换地理坐标与动物地理区划图叠加后产生蚜虫地理分布图。结果显示出这个属主要分布在东北区南部、华北区、华中区、华南区和西南区东部(中国南部和东部)。根据地理分布图及有关统计分析，认为东北区南部—华北区北部和华中区南部一东南部是这个属在中国的分布中心、分化中心和特有中心。同时，利用寄主植物的分布，探讨了中国侧棘斑蚜属的分布与寄主植物分布之间的关系。

GEOGRAPHICAL DISTRIBUTION OF THE GENUS TUBERCULATUS IN CHINA (APHIDIDAE, MYZOCALLIDINAE)

The geographical distribution of the genus Tuberculatus (Aphididae: Myzocallidinae) in China were analysed using GIS software. A distribution database of Tuberculatus species was compiled based on specimen collection localities. This was overlapped with zoogeographic regions to develop distribution maps. Tuberculatus mainly occur in southern parts of Northeast China, North China, Central China and South and Southwest China. Based on the geographical distribution and statistical analyses, southern of Southeast China, northern North China and southern Central China are the likely center of distribution, differentiation center and endemic center of this genus respectively. Some interesting traces of vicariant distribution at species or subgenus level are clearly apparent on the maps.
