松褐天牛的综合防治措施分析

Analysis of Integrated Control Measures for Monochamus alternatus Hope

作为我国北方荒山荒坡修复、防风固沙、水土保持及城市绿化的主要树种,松科类树种栽植的纯林面积较大,致使松科类病虫危害越来越严重。近几年来,松褐天牛在太白山浅山林区越来越严重,林场从2016—2021年连续6年对浅山区油松林发生的松褐天牛虫害进行了多种措施的综合防治实践,效果良好,也积累了一些防治经验。基于此,概述了松褐天牛在国内的分布与危害情况及其生物学特性,结合查阅大量林业病虫害防治资料,归纳整理了防治松褐天牛的方法,包括天牛信息素诱捕防治、白僵菌寄生感染防治、花绒寄甲生物天敌防治、营林综合措施防治、化学药剂防治等内容,通过对以上综合防治措施进行总结归纳,以期为松褐天牛危害林区的防治工作提供参考。

Pine tree species,as the main tree species of desert mountain and slope restoration,windbreak and sand fixation,soil and water conservation and urban greening in northern China,the pure forest area of planting is large,which caused the damage of pine diseases and insects to become more and more serious.In recent years,the occurrence of Pinaceae has become more and more serious in the shallow mountain forest area of Taibai Mountain.From 2016 to 2021,our forest farm carried out a variety of comprehensive control practices on the pest of Monochamus alternatus Hope in the shallow mountain area,and gained some control experience.In this paper,the distribution,damage and biological characteristics of Pinus tabulaeformis forest in China were summarized.Based on a large number of forest pest control data,the following control methods were summarized,including pheromone trapping and control,Beauveria bassiana parasitic infection control,natural enemies control,forest comprehensive measures control,chemical control and so on.The above comprehensive control measures were summarized and published in order to provide reference for the prevention and control of Longhorned pine in forest areas.
