松毛虫是森林害虫中发生量大、为害面广的主要森林害虫,是世界性害虫,主要为害云南松、马尾松、云南油衫等,是大桥乡云南松的主要害虫之一,每年造成的经济损失不少。被松毛虫为害着的林区,很难以控制其扩散与蔓延,灾情严重区域似火烧过一样,称为“无烟火灾”。防治上用生物、物理、化学等综合性技术措施,突出战略性防治、生物性因素控制和技术性的组装运用,科学设计,高效运作,辅以人为因素调整,使松毛虫发生逐步向动态平衡方向转化,在治理上逐步从被动防灾向主动性控灾方向转变。根据松毛虫综合管理的指导方针,采取“因地制宜、统筹全局、合理规划,分类施策,分步实施,重点突破、逐次推进”的防治策略,从几方面进行有效预防和防治,以促进大桥乡云南松能快速、健康和可持续发展。
Dendrolimus is one of the major forest pests in forest pests. It is a worldwide pest, and it is mainly caused by Pinus yunnanensis, Pinus massoniana and Yunnan lingerie. It is one of the major pests in Pinus yunnanensis, A lot of economic losses. It is difficult to control the spread and spread of forest areas harmed by pine caterpillars. It is also called a “smokeless fire.” Prevention and control of biological, physical, chemical and other comprehensive technical measures, highlighting the strategic prevention and control, biological factors control and technical assembly and use, scientific design, efficient operation, supplemented by human factors, so that the occurrence of pine caterpillar gradually to the direction of dynamic balance Transformation, and gradually change from passive disaster prevention to active disaster control in governance. According to the guidelines for integrated management of pine caterpillars, we will take effective measures to prevent and control such diseases as “adjusting measures to local conditions, coordinating the overall situation, rationally planning, categorizing and implementing policies, implementing step by step, focusing on breakthroughs and pushing forward one after another” Township Yunnan pine can be rapid, healthy and sustainable development.
