油桐尺蠖(Buzura Suppressaria Guenee)又称大尺蠖,是为害茶树的主要尺蠖蛾类害虫,在浙江年发生2～3代,主要为害夏、秋茶。由于幼虫有明显的暴食期,在种群密度大的时候往往会造成灾害。关于幼虫的取食量,王问学等(1982,昆虫知识)曾以梧桐树叶为饲料作过取食叶面积的测定,但以茶叶为饲料的取食量测定未见详细报道。笔者1982年用茶叶对该虫进行了饲养观察,现将主要结果整理如下。
Buzura Suppressaria Guenee, also known as Lantana camara, is the major pest moth infestation in tea trees. It occurs in Zhejiang Province for 2-3 generations, mainly affecting summer and autumn tea. Because larvae have a significant gluttony period, they often cause disasters when the population density is high. On larval feeding, Wang asked Xue et al (1982, insect knowledge) had Indus leaves as feed for the determination of feeding leaf area, but the feed intake of tea as the feed has not been reported in detail. The author of the worm in 1982 with the feeding observation, now the main results are organized as follows.
