我国热带地区外来入侵昆虫发生与分布

List of alien invasive insects in tropical regions of China

外来生物入侵是当今世界的热点问题之一,对生态环境、人类健康和农林业生产构成巨大的威胁。热带地区因其优越的自然气候条件,成为我国外来入侵生物发生与危害的重灾区。本文以外来入侵昆虫为研究对象,通过文献调研和数据库资料查询,对外来入侵昆虫在我国热带区域的分布、种类、原产地、入侵地等进行综述。我国热带区域外来入侵昆虫种类共计72种,主要集中在云南(51种,占70.83%)、海南(46种,占63.89%)、广东(45种,占62.5%)、广西(39种,占54.17%)等省,其中以半翅目(24种,33.33%)、鞘翅目(21种,占29.17%)昆虫为主。亚洲和南美洲是我国热带地区外来入侵昆虫的主要来源地,分别有26种(占36.11%)和12种(占16.67%)。这些分析结果可为我国热带地区外来入侵昆虫的综合防控及相关政策的制定提供参考。

Invasive species pose a major threat to the environment,human health,agriculture and forestry.Due to their climate,tropical areas have been hardest hit by invasive species.Based on a information obtained from a literature review and database data query,this paper reviews the distribution,species,origin and range,of invasive insects in tropical regions of China.There are 72 species of invasive insects in tropical areas of China,mainly in Yunnan(51 species,70.83%),Hainan(46 species,63.89%),Guangdong(45 species,62.5%),and Guangxi(39 species,54.17%).The dominant orders are the Hemiptera(24 species,33.33%),Coleoptera(21 species,29.17%).Asia and South America are the main sources of invasive insects that have colonised tropical regions of China,contributing 26(36.11%)and 12 species(16.67%),respectively.These results provide a reference for the comprehensive prevention and control of invasive insects and related policy formulation in tropical regions of China.
