摘要
该文对落叶松球果花蝇种团Strobilomyiaspp .的危害特点、延长滞育及不同经营条件下种子园内的发生情况及以前获得的一些未报道的数据进行了补充。调查发现 ,球果产量高时 ,受花蝇危害率较低 ,第 2年花蝇的延长滞育率则高 ;球果产量低时 ,受花蝇危害率较高 ,第 2年花蝇的延长滞育率则低。
More information was reported here on bionomics and damage of larch cone flies,Strobilomyia spp.,an important pest guild to larch cones in northeastern China.Most of these data or information were unpublished,synthesized from a previous project with some additional data gathered recently on diapause.Both damage and bionomics of cone files were closely synchronized with larch cone development,especially with regarding to its diapause,which fluctuated with cone production.
