| 摘 要： | 松果梢斑螟(Dioryctria pryeri)是我国松属(Pinus)针叶树重要害虫之一,该虫属寡食性害虫,在我国北方主要危害油松(Pinus taebulaeformis)(李宽胜,1992;李新岗,2002).此虫1年1代,以2龄幼虫越冬,幼虫在5-6月份钻蛀球果及新梢,致使嫩梢枯萎,球果干瘪,影响油松的正常生长发育和种子生产(袁荣兰等,1990;姚远等,1996),特别是结实期的油松种子园、母树林受害最为严重.松果梢斑螟可与油松球果小卷蛾(Gravitarmata margarotana)一起危害油松球果,在油松良种基地造成巨大的产量损失(李新岗等,2006;2007).

| Abstract: | GC-MS was used to determine the composition and content of the terpene volatiles collected from uninfested and infested cones of Chinese pine (Pinus tabulaeformis) by means of solid phase microextraction (SPME) during the host-selection and ovipositive period of Dioryctria pryeri.The electroantennogram (EAG) of D.pryeri male and female adults was tested in responses to the uninfested and infested cone,and 6 terpene volatiles and their blends.The results showed that D.pryeri had a greater EAG response potent... |
