落叶松红腹叶蜂生物学特性与防治技术分析

Analysis on Biological Characteristics and Control Techniques of Larch Red Bellied Sawfly

在林业养护管理阶段,防治病虫害是重要的工作内容之一。明确常见病害的生物学特性方能拟编出针对性更强、实用价值更高的防治方案。落叶松叶蜂为落叶松生长阶段的常见虫害,在东北、西北等诸多地区均有分布,大规模成灾时将会啃食大片落叶松林针,严重时造成落叶松枯死。在解读红腹叶蜂生物学特性的基础上,探究几点较为有效的防治技术办法,以供参考。

In the stage of forestry management,the prevention and control of diseases and pests is one of the important tasks.Only by clarifying the biological characteristics of the disease can we compile a targeted and practical control plan.Sawfly is a common pest in the growth stage of larch.It is distributed in the northeast and northwest regions.It will eat a large number of leaves and even cause trees to wither.Based on the understanding of the biological characteristics of red bellied sawfly,the effective control techniques and methods were explored for reference.
