靖远松叶蜂(Diprion jingyuanensis)是危害油松的重大森林害虫,1994年定为新种。该文对其形态、生物学特性、与环境因子的关系及主要天敌作了深入研究。此虫在山西省沁源,一般一年1代,以茧内预蛹(拟)在落叶层下越冬,成虫于6月间大量出现。少数有滞育现象,两年完成1代。雌雄性比为1:0.6,每雌产卵120粒~229粒,有孤雌生殖现象。幼虫共8龄,每头幼虫取食针叶60根左右。纯林、疏林、阴坡虫口密度大。靖远松叶蜂病毒(NPV)、白僵菌、金头赘寄蝇、大山雀等 22种天敌是制约该虫种群数量的重要环境因素。
Jingyuan pine leaf bee (Diprion jingyuanensis) is a major forest pest endanger pine, in 1994 as a new species. The article made a deep research on its morphological and biological characteristics, the relationship with environmental factors and the main natural enemies. The insects in Qinyuan, Shanxi Province, generally 1 generation a year, with cocoon pre-pupa (to be) over the winter in the deciduous layer, adults appear in large numbers in June. A few have diapause phenomenon, two years to complete a generation. Male-female ratio of 1: 0.6, 120-299 eggs per female, with parthenogenesis. A total of 8 larvae of larvae feeding about 60 needles. Pure forest, sparse forest, cloudy slope population density. 22 kinds of natural enemies, such as Jingyuan pine leaf bee virus (NPV), Beauveria bassiana, gold-headed superfluous flies and big tits were the important environmental factors restricting the population of this pest.
