三叶草斑潜蝇的入侵、鉴定及在中国适生区分析

Invasion and identification of Liriomyza trifolii and its potential distribution areas in China

介绍了2005年12月首次发现入侵中国大陆的三叶草斑潜蝇Liriomyzatrifolii(Burgess)的形态特征及其与近缘种的形态区别、入侵历史与危害性;利用GARP生态位模型对三叶草斑潜蝇在中国的潜在适生区进行了分析预测,结果表明该虫在中国的潜在适生区涉及范围广,以东部地区的最适宜潜在适生区为主,它的潜在适生区涵盖了热带、亚热带和暖温带等3种气候类型;依据中国大陆目前的发生情况提出对该种入侵害虫的监测方法与防控建议。

The paper gives an introduction of the new invasive species, American serpentine leafminer, Liriomyza trifolii （Burgess）, including its morphological characters for identification,invasion history and economic importance. GARP model was used to predict its potential distribution in China. The results show that it could distribute in wide areas in China. Its potential distribution areas involve tropic, subtropic and temperate climate zones. The most suitable areas of the pest in natural conditions lie in East China. Thus, it is urgent to take strict measures to reduce its population and suppress its distribution. The monitoring methods and suggestions for the control of this pest are also discussed according to the current situation in the China's Mainland.
