云南松脂瘿蚊研究 Ⅱ-天敌和治理

A Study on Yunnan Pine Resin MidgeⅡ-Natural Enemies and Integrated Pest Management

云南松脂瘿蚊（ Ｃｅｃｉｄｏｍｙｉａ ｙｕｎｎａｎｅｎｓｉｓ Ｗｕ ｅｔ Ｚｏｕ）是云南松（Ｐｉｎｕｓ ｙｕｎｎｅｎｓｉｓ）的重要枝梢害虫．以云南省江边林业局的冲头和鲁地林区为基地，在弄清该害虫生物学、生态学特性的基础上，对云南松脂蚊天敌的保护利用进行了研究；以在森林生态系统内充分发挥生物多样性的效能，促进系统内生态平衡的理论为指导，提出在落实合理的林业技术措施的基础上，以保护和培育林下植被，促进自然生防为主。

Pine resin midges Cecidomyia yunnanensis is a gall forming insect of pine tree in Yunnan,especially in the plantation of the province.The natural enemies of resin midges were closely studied to provide a reference for suggesting the management measures of the pest.Guided by the theories of bringing the function of the biodiversity in forest ecosystem into full play and promoting the ecological balance in the system, the integrated management strategies were made:basing on rational forest management technologies,mainly depending on protecting and developing vegetation cover under tree canopy,promoting natural biological control,and cutting off the infested branches and limited chemical control in adult stage.
