摘要
螺旋粉虱Aleurodicus disperses Russell是一种危险性的入侵害虫,作者于2006年4月,在我国海南陵水首次发现,分析可能是从台湾引入。文章记述螺旋粉虱在海南的发现过程、该种的野外识别及室内鉴别特征,列出海南发现的27种重要寄主植物(这些植物涉及果树、园林和农作物)和几种捕食性天敌,并附有特征图和彩色照片。最后分析其在海南发展趋势及向大陆扩展的可能性,福建、广东、广西等南方省区应密切关注该虫的发展。
The spiraling whitefly, Aleurodicus dispersus Russel, is a destructive invasive pest and was first found in Hainan, China, in April 2006, likely coming from Taiwan. The present paper records its collection, givers out the morphological characteres differentiated from other whitefly genera and species, lists 27 host plants of more than 70 species known in Hainan, covering fruit, ornamental and agricultural crops, and several predators, provided with illustrations and color pictures. Finally, the paper discusses the possibility of its future expansion, and suggests regular and close observations on its possible expansion into the tropical provinces of the China's mainland.
