【摘要】 原产于欧洲、非洲等地的意大利蜜蜂几个世纪以来被人类频繁地有意引入到其它国家和地区 ,然而其在带来经济利益的同时 ,意大利蜂凭借其在诸多方面的竞争优势对当地物种和生态系统产生不利影响。本文主要阐述了意大利蜜蜂引入后对我国本地种中华蜜蜂造成的负面效应 :①中华蜜蜂种群数量急剧下降 ,甚至在某些地区已到了灭绝的边缘 ;②影响了以中华蜜蜂作为主要传粉媒介的早花乔木、灌木和草本植物的正常繁育 ,从而降低了物种多样性 ,破坏了群落结构及其稳定性。更多还原

【Abstract】 The Italian bee Apis mellifera L. is native to Europe and Africa, and was introduced into South America, North America and Asiaa few centuries ago. The alien species outcompeted with native bees and has caused serious consequences. The impacts of the introduced A. mellifera L. on the A. cerana Fab., native to China, were described in this paper. Native bees have sharply cut down in number, even are in danger of becoming extinct in some areas. Plant community structure has changed and plant diversity declined in local areas.更多还原
