| 摘 要： | 主要介绍热带亚热带入侵害虫螺旋粉虱Aleurodicus dispersus Russell的形态特征、分布、寄主与生物学特性;利用DYMEX软件分析螺旋粉虱在我国潜在的分布区。模型分析结果表明,最适宜的潜在的适生区主要集中在中国的南部,包括海南、广东、广西以及台湾等的大部分区域;在云南只有零散的潜在适生区;而广大的西北和东北不利于该虫的生存;依据适生性风险预测结果,提出了应急处理措施。

| Abstract: | This paper gives an introduction of invasive alien species, Aleurodicus dispersus Russell, including its morphological characters, distribution, hosts and biological characters. DYMEX software was used to predict its potential distribution in China. The results show that it can distribute in southern China. The most suitable areas for this pest establishment are Hainan, Guangdong and Guangxi Provinces as well as Chinese Taipei, China, and also can occur in some places of Yunnan Province. Moreover, DYMEX analysis shows that the Northwestern and Northeastern areas of China are not suitable for its survival. Strategies for its emergency treatment and management are outlined based on its risk assessment. |
