近年来随着我国杨树种植面积的不断扩大,白杨透翅蛾的发生和危害也越来越严重。白杨透翅蛾的幼虫主要危害杨树的枝干和顶芽,从顶芽入侵时使被害处形成枯萎、下垂,抑制了顶芽的生长,形成秃枝,杨树被害后形成虫瘿,遭遇大风容易折断,严重的影响了杨树的生长,对树苗质量造成了很多大的威胁,使杨树材质下降,影响杨树存活率和保存率。本文从白杨透翅蛾的危害特点和生物学特性做分析,结合白杨透翅蛾的发生规律制定了科学而又全面的防治措施。
In recent years, with poplar planting area of our country continues to expand, Poplar moth’s occurrence and harm is also more and more serious. The poplar moth larva mainly endanger the branches and the top buds of poplars, causing the victims to withered and droop from the top bud invasion, inhibiting the growth of the top buds and forming bald branches, forming poplar after the poplar trees were killed, encountering Gale easily broken, severely affected the growth of poplar, the quality of saplings caused by many major threats to the poplar material decreased, affecting poplar survival rate and preservation rate. In this paper, we analyzed the harmful characteristics and biological characteristics of Populus euphratica, and developed a scientific and comprehensive prevention and control measures based on the occurrence of Populus toxiens.
