保定市绿化带林木蛀干害虫发生情况与防治效果研究

Study on the Occurrence and Control Effect of Tree Trunk Boring Pests in Green Belts of Baoding City

摘要: 绿化带在生态保护上起到了非常重要的作用，由于蛀干害虫的普遍发生，不仅影响了树势，对调节生态等方面带来了不必要的影响。本研究以南水北调唐县段、顺平和保定府河公园、一分厂等试验区的蛀干害虫为研究对象，通过实地调查蛀干害虫的种类、发生情况以及发生动态，在关键时期进行防治。具体研究如下：南水北调唐县段渠道绿化带主要的蛀干害虫为芳香木蠹蛾和榆木蠹蛾，详细调查了其发生动态，掌握了各个虫态发生的关键节点。由于严禁使用有毒的化学农药，因此采取了定向施药的方法进行防控，并取得了理想的防治效果；顺平桃园主要的蛀干害虫为桃红颈天牛，而保定府河公园和一分厂主要的蛀干害虫为光肩星天牛和吉丁虫。针对蛀干害虫为害的关键时间和为害特点，采用蛀孔注药和喷雾处理的方法进行防控，防治后控制率高达90%以上。

Abstract: Green belt plays a very important role in ecological protection. Because of the widespread occurrence of decay the pests, it not only affects tree potential, but also brings unnecessary effects on ecological regulation. In this study, decay the pests in Tangxian section of South-to-North Water Diversion Project, Fuhe Park in Shunping, Baoding and other experimental areas were taken as the research objects. Through field investigation on the species, occurrence situation and occurrence dynamics of dry-worming pests, the prevention and control of dry-worming pests in the critical period were carried out. Specific research is as follows: The main decay the pests in the greenbelt of the channel of the South-to-North Water Transfer Project in Tangxian County were the Aromatic wood moth and Elm moth. The occurrence dynamics of these pests were investigated in detail, and the key nodes of each insect state were obtained. Because the use of toxic chemical pesticides is strictly prohibited, the method of directed application is adopted for prevention and control, and the ideal prevention and control effect has been achieved; in Shunping Taoyuan, the main decay the pests were peach red necked longhorn beetle, while in Baoding Fuhe Park and one branch plant, the main dry-worming pests were Anoplophora glabripennis and the Buprestid beetle. In view of the critical time and characteristics of the dry moth pests, the method of injecting drug into the hole and spraying treatment was adopted for prevention and control, and the control rate reached more than 90% after prevention and control.
