摘　　要：尺蛾是近年来危害荔枝枝梢的一类重要害虫。其种类主要有粗胫翠尺蛾（Thalassodes immissaria Walker）、间三叶尺蛾（Sauris interruptaria Moore）、青尺蛾（Anisozyga sp.）、油桐尺蛾（Buzura suppressaria Guenée）和绿额翠尺蛾（Pelagodes proquadraria Inoue）等。该类害虫1年多代,其中油桐尺蛾1年34代,其它4种尺蛾1年78代,四季均有发生,以幼虫大量取食新梢嫩叶、花穗及幼果,以夏秋梢受害最重,大发生时可将整株树的嫩梢嫩叶吃光,对荔枝生产威胁很大。笔者总结了荔枝主要尺蛾的分布与危害、形态特征差异、生活习性以及发生规律和防控策略,并提出了一些研究设想和建议。Litchi geometrid moths have become one of the serious pests in Litchi in recent years,which infest young leaves and shoots.The main types of geometrid moths are Thalassodes immissaria Walker,Sauris interruptaria Moore,Auisozyga sp.,Buzura sappressaria Guenée and Pelagodes proquadraria Inoue etc.They occur several generations a year,of which B.suppressaria occurs 34 generations and the other 4 species occur 78 generations.Litchi geometrid moths make damage to litchi in all the seasons.Their larvae swallow a large number of young shoot,leaves,spikes and fruits and even eat up all the young leaves and twigs of litchi tree in summer and autumn,which make a great threat to litchi production.In this review,distribution,damage status,differences of morphological character,life habit,occurrence pattern and control techniques of litchi geometrid moths were summarized and some research ideas and suggestion were discussed.
