油松是中国北方广大地区最主要的造林树种之一。油松适应性强,根系发达,树姿雄伟,枝叶繁茂,有良好的保持水土和美化环境的功能。2007年,在甘肃省迭部县林区首次发现中华松针蚧危害,该虫害造成油松林长势严重衰退,枝梢枯黄,使原本比较脆弱的生态环境遭到破坏。此后,又有多处地区遭受虫害,造成严重经济损失。为尽快抑制该虫的危害,找到安全有效、经济简易的防治方法,对中华松针蚧的生物特征及近年来虫灾发生事件进行研究与分析,并就防治技术提出几点建议。
Pinus tabulaeformis is one of the most important afforestation species in vast areas of northern China. Poismatis adaptability, developed roots, majestic tree pose, lush foliage, good soil and water to maintain the function of beautifying the environment. In 2007, for the first time, Pinus thunbergii was found in the forest of Diebu County, Gansu Province. The pest caused the serious decline of Pinus tabulaeformis forest and the yellowish shoots, which damaged the originally fragile ecological environment. Since then, many areas have been affected by pests, causing serious economic losses. In order to restrain the harm of the pest as soon as possible, to find a safe, effective and economical method of prevention and treatment, the biological characteristics of the pine needles and pest disasters in recent years to conduct research and analysis, and put forward some suggestions on prevention and control technology.
