云南扶桑绵粉蚧的发生及防治

扶桑绵粉蚧是一种全球恶性入侵害虫,2008年传入我国,目前已有13个省区报道其为害,2009年在云南省被发现,截至2013年3月,云南省共8个州(市) 10个县(市)已有分布。扶桑绵粉蚧寄主范围广,危害性大,适应性强。同时,云南省花卉、蔬菜调运及进出口贸易频繁,加之气候类型丰富、水热条件优越、自然地理环境复杂多样、动植物资源丰富等优势,有利于扶桑绵粉蚧的入侵、定殖与扩散,易造成较大的经济损失。目前,关于云南省扶桑绵粉蚧的研究仍然缺乏,现就扶桑绵粉蚧在云南的发生现状、潜在风险和防治措施等方面进行概述,以期为该虫的有效防范提供参考。

The occurrence and control of the invasive scale insect, Phenacoccus solenopsis Tinsley in Yunnan Province

Phenacoccus solenopsis Tinsley is an important alien pest which has invaded China since 2008. P. solenopsis has been found in 13 provinces, and was first detected in Yunnan Province in 2009, and by March 2013, P. solenopsis was found at 10 sites belonging to 8 districts. The complicated topography, diverse climate, presence of diverse ecosystem types, the frequent distribution of flowers and vegetables in import and export trade make the province vulnerable to further spread and damage by this pest. However, there is still a lack of research on P. solenopsis in Yunnan Province. This paper summarizes the occurences, potential risk in Yunnan Province and available management measures.
