马尾松林培育常见害虫发生机制及防治研究进展

Research Progress on the Mechanism and Prevention of Common Pests in the Cultivation of Pinus massoniana

马尾松害虫按照食性不同可分为:食叶类害虫、钻蛀性害虫、刺吸式害虫、蛀干式害虫、食根性害虫。文章重点对马尾松幼林和成林培育过程中易受虫害种类、虫害发生机制及具体防治措施等问题进行了系统的总结,明确了我国对马尾松的害虫防治以化学防治为主,物理防治和生物防治为辅,部分地区已将生物防治作为主要的工作重点的现状,提出了以营林措施为基础,以生物防治为主,协调使用其它技术措施,以降低虫口密度,缩小虫害范围,进而改善林分生长环境,增强森林自控能力,降低虫害造成的经济损失,做到有虫不成灾的综合防治的观点。

In this paper,the Pinus massoniana pests are divided into leaf-feeding pests,drill-bit pests,sucking pests,dry-type pests,and root-feeding pests according to different feeding habits.The paper systematically summarized the types of pests,the mechanism of insect pests and the specific control measures during the cultivation of young Pinus massoniana and adult forests.and clarifies that China′s pest control of Pinus massoniana is dominated by chemical control,physical control and biology.Supplemented by prevention and control,in some areas,biological control has been the main focus of work.Proposed point of view that based on forest management measures,biological control is the main focus,and other technical measures are coordinated to reduce the density of insects,reduce the range of pests,and improve the forest grows environment,enhance the ability of forest self-control,reduce the economic losses caused by pests,and achieve the comprehensive prevention and controlling pests.
