世界毁灭性检疫害虫番茄潜叶蛾的生物生态学及危害与控制

Bioecology,damage and management of the tomato leafminer Tuta absoluta( Meyrick)( Lepidoptera: Gelechiidae),a worldwide quarantine pest

番茄潜叶蛾原产于南美洲的秘鲁,严重危害多种茄科作物,是最具毁灭性的世界检疫性害虫,严重发生地块番茄减产80%~100%。该虫主要借助农产品的贸易活动进行远距离传播扩散。截至2017年,番茄潜叶蛾已在全世界的85个国家和地区发生(以及在22个国家和地区疑似发生)。目前,我国尚没有该虫分布,然而其一旦入侵,将对我国的番茄和马铃薯产业构成巨大威胁。从番茄潜叶蛾寄主范围、危害特点及造成的经济损失、生物生态学习性、地理分布和传播扩散途径、防控措施等方面进行概述,以期为该虫的有效防范提供参考。

The tomato leafminer Tuta absoluta （Meyrick）, native to Peru, South America, is a devastating quarantine pest worldwide. If no control measures are taken, the pest can cause up to 80%-100% yield losses in tomato crops. The pest mainly spread by long-distance trade in agricultural products. As of 2017, the occurrence of T. absoluta has been reported from 85 countries and regions around the world （and its presence suspected in 22 countries and regions）. Currently there are no records of its occurrence in China. However, if invaded, it would pose a grave threat to tomato （as well as potato） production. This paper summarizes the information on the host plant range, damage, biological and ecological characteristics, geographical distribution, spreading pathways, and available management measures of this pest.
