柚橙带夜蛾Hyblaca pucra Cramer又称柚木肖弄蝶夜蛾,属鳞翅自驼蛾科(Hyblaeidae)。在柚木Tectona grandis Linn.原产地,该虫与柚木野螟Pyrausta machoerlis Walker同为柚木的主要害虫。1975年在我所柚木林对33株树调查(平均树高7.2米,胸径8.3厘米),一株树最多有23条幼虫,平均7条,嫩叶几乎被吃光。目前,该虫发生量虽不及柚木野螟多,但已开始对幼苗和幼林构成威胁。根据1983年在云南省德宏自治州的调查,有3,000多亩柚木林普遍被害,200多亩被吃光,星火烧状。关于该虫在我国的为害情况,以前未见报道,现将我们的初步观察结果整理如下。 Pomelo orange bandworm Hyblaca pucra Cramer, also known as teak Xiao clubbing moth, is a lepidoptera from the genus Camelidae (Hyblaeidae).
