摘要/Abstract

摘要：

紫胶虫是重要的资源昆虫。本文结合云南西南部、东南部地区云南紫胶虫自然分布区调查结果及相关资料的整理和分析，对生态因子在云南紫胶虫地理分布中的作用进行了归纳。结果表明：云南紫胶虫的地理起源可能是印度洋地区的南亚。云南紫胶虫主要分布于怒江流域及支流、澜沧江流域及支流、红河流域及支流、伊洛瓦底江流域支流河谷两岸半山坡。气候因子中的温湿度组合是决定云南紫胶虫地理分布的主要因子，而寄主植物分布对云南紫胶虫地理分布也有限制作用。云南特有的流域地形、山脉走向及所形成的小气候特点决定了云南紫胶虫在云南的地理分布格局。

Abstract:

Based on the investigation results of Kerria yunnanensis Ou et Hong natural distribution areas in southwest and southeast of Yunnan Province and the related literatures, the role of ecological factors on geographic distribution of K. yunnanensis was reviewed and analyzed. The results show that K. yunnanensis might originate from South Asia in Indian Ocean areas. Naturally, K. yunnanensis is distributed mainly on half slopes of valley straits of Nujiang River and its subsidiary currents, Lancangjiang River and its subsidiary currents, Honghe River and its subsidiary currents, and Irrawaddy River subsidiary currents. The combination of temperature and relative humidity is identified as the principal factor limiting geographic distribution of K. yunnanensis, which is also related with the distribution of its host plants. The unique river valley topography, mountain range alignment, and local weather characteristics in Yunnan Province determine the geographic distribution pattern of K. yunnanensis.
