甘伪小眼夜蛾生物学特性研究初报

A Study on Biological Characteristics and Control of Pseudopanolisransuensis Chen

甘伪小眼夜蛾 (Pseudopanolis kansuensis Chen)是甘肃新发现危害油松的 1种害虫 ,80年代末期 ,在靖远县哈思山林区暴发成灾。1年 1代 ,以老熟幼虫在树冠下土壤中化蛹越冬。幼虫 1～ 3龄期用灭幼脲 号胶悬剂加“功夫”乳油混配 ,飞机低量喷雾 。

Found recently in Gansu province,Pseudopanolis kansuensis Chen is a kind of in- sect pest which damages Pinus tabulaeformis.It was rampant in the forest area of Hasishan Mountain,Jingyuan county,Gansu province in the end of eithsies.It produces one generation per year,and overwinters as an old larvae which becomes pupae in the soil under the tree crown.The effective method to control it is to spray aerially small amount of a mixed solu- tion in1～ 3instar of the larvae stage.The solution consists of the flowable formulation of di- flubenzuron- and a dilute solution of karare.
