摘要
杜仲梦尼夜蛾（ＯｒｔｈｏｓｉａｓｏｎｇｉＣｈｅｎｅｔＺｈａｎｇｓｐ．ｎｏｖ）是为害杜仲重要食叶害虫之一。经过对杜仲梦尼夜蛾生物学特性进行观察，该夜蛾食性单一，在慈利县一年发生三代。天敌致死率为３３．５７％～４５．１８％。用Ｂ．ｔ乳剂和灭幼脲进行防治试验。
Orthosia songi is one of the main defoliators occurring in Eucommia ulmoides. Observations on the biological characteristics of this pest showed that it is monophagous, and three genera tions occurred annually in Cili County. The lethalities caused by natural enemy and insecticides to control the pest were 33.57%～45.18% and 87% respectively.
