粉虱蚜属蚜虫的分布格局及其成因探讨(同翅目:扁蚜科)

本文以世界分布的 5种粉虱蚜属AleurodaphisvanderGoot蚜虫为材料 ,研究了该属的地理分布特点 ,现代分布格局及可能的起源。同时 ,利用蚜虫与寄主植物协同进化的关系 ,并结合古地理和古生物等方面的资料 ,探讨了粉虱蚜属的现代分布格局形成的可能原因。粉虱蚜属为典型的东洋区成分 ,但在中国大陆其分布向古北界有所渗透。根据该属蚜虫现代分布特点 ,推测中国的华中区是该属的现代分化中心。另外 ,推测形成该属现代分布格局的原因可能是由于各大陆之间的接合与分离

STUDY ON DISTRIBUTION PATIERN AND THE FORM OF DISTRIBUTION PATTERN OF THE GENUS ALEURODAPHIS(HOMOPTERA: HORMAPHIDIDAE)

This paper studies on geographical distribution, recent distribution pattern and possible origin of Aleurodaphis van der Goot in the world. By re evolution relationship of aphids and host plants and materials of paleogeography and paleontology, the formed cause of recent distribution pattern is probed in this paper. The aphids of Aleurodaphis are typical Oriental species; but, slightly permeated in Palaearctic on Chinese continent. Center China region may be recent distribution center of Aleurodaphis. In addition, the formed cause of recent distribution pattern might have been joint and separation among every continents.
