皖南地区马尾松毛虫防治技术研究

Research on the prevention and control techniques of Dendrolimus punctatus in southern Anhui Province

马尾松毛虫是松类树种常见害虫,对林业生产和林业生态造成较大危害。本文通过分析皖南地区马尾松毛虫的发生特点、发生规律及发生原因,提出该害虫的防治策略,并阐述了其绿色防治技术要点,为该地区马尾松毛虫的防治提供参考。马尾松毛虫的发生与寄主植物、自然气候及天敌等因素有关,在森林群落平衡被破坏、自然环境异常变化、害虫自身遗传变异及管理不到位等情况下易发生。生产上可采取划区治理,分区施策;强化监测,掌握虫情;绿色防治,压低虫口;营林改造,自然消亡等防治策略,通过营林措施、物理防治、化学防治、生物防治及天敌利用等防治措施进行综合防治。

The Dendrolimus punctatus is a common pest of the pine family,which can cause significant damage to forestry production and ecology.The occurrence characteristics,patterns,and reasons of the Dendrolimus punctatus were analyzed in the southern Anhui Province region,proposed prevention and control strategies for the pest,and elaborated on the key points of green prevention and control techniques,providing references for the prevention and control of harmful organisms in the forestry of the southern Anhui Province region.The occurrence of Dendrolimus punctatus is related to host plants,natural climate,and natural enemies.It is prone to occur when the balance of forest communities is disrupted,natural environmental changes are abnormal,the pest itself undergoes genetic variation,and management is not in place.In production,it is possible to adopt strategies such as zoning management,targeted implementation;strengthening monitoring,mastering pest situations;green control,reducing pest populations;forest transformation,natural extinction,and other control strategies.Comprehensive prevention and control measures are carried out through silvicultural measures,physical control,chemical control,biological control,and the utilization of natural enemies.
