新疆蚜虫的物种多样性研究

ON SPECIES DIVERSITY OF APHIDS FROM XINJIANG UYGUR AUTONOMOUS REGION, CHINA

从分类阶元、寄主植物和寄生部位等角度系统研究了新疆蚜虫类昆虫的物种多样性,共发现蚜虫5科57属183种,寄主植物55科192属。无论在属级水平还是在种级水平,蚜科均有绝对优势,分别占新疆所有属数和种数的64.90%和65.60%。结果表明,新疆蚜虫的地理分布具有明显的纬度和经度梯度性,这与天山山脉在新疆的地理位置和走向是紧密相关的。另外,受植被分布和人类活动的影响,新疆蚜虫还具有明显的岛屿状分布特征。

This paper reviews the species diversity of aphids in Xinjiang Uygur Autonomous Region, China from aphid taxa, host plants and infesting locations. There are 183 known species belonging to 57 genera and 5 families in this region. Host plants of aphids in this region lie in 192 genera and 55 families. Aphididae is dominant in the numbers of genera and species, and includes 64.90% of known genera and 65.60% of known aphids in this region. The geographical distributions of aphids show obvious gradient changes in latitude and longitude in the region, and the geographical distributional pattern is closely related to the geographical position and direction of Tianshan Mountains. Based on the distributions of host plants and the activities of human beings, the geographical distribution of aphids in this region presents obvious island-like pattern.
