摘要
松褐天牛是松材线虫中常见的一种,是危害松林最为突出的病害之一,其一生要经历卵、幼虫、蛹、成虫4个阶段,是典型的钻蛀性害虫;其在病弱和濒死的树枝中产卵成行,导致树木快速枯死,不仅威胁林区生态环境安全,还会造成巨大的社会经济损失。该文结合松褐天牛的形态特征、发病规律、产生原因、危害情况等,有针对性地提出了防治措施,以供业界同行今后工作参考和借鉴。
Monochamus alternatus is a common species of pine wood nematode and one of the most prominent diseases endangering pine forest.It goes through four stages:egg,larva,pupa and adult;It lays eggs in the weak and dying branches,resulting in the rapid death of trees,which not only threatens the ecological environment security of forest areas,but also causes huge social and economic losses.Combined with the morphological characteristics,incidence law,causes and harm of Monochamus alternatus,this paper puts forward the control measures,which can be used as a reference for colleagues in the industry in the future.
