一般影响 亚洲长角牛甲虫 光肩星天牛(Anoplophora glabripennis)会慢慢地杀死树木，估计约3-5年的时间，但有些树种可能需时更久。在原生地中国约有40％的白杨树造林区已经遭受危害（230万公顷）。单单在5个省中，超过240个县市已经遭受虫害（总计23万公顷），且在3年之间，宁夏省估计已有5000万棵树被砍伐（1991至1993年）。光肩星天牛造成严重损害的地区约为北纬21-43度，东经100-127度（包括中国的4个气候区：南至热带过渡区北至暖温带、温带、冷温带与干旱区） 2001年5月，美国分别在纽约及芝加哥砍伐掉5286棵及1547棵遭受虫害的树。2001年8月，奥地利也有47棵遭受虫害的树木遭到砍伐。          地点特有的影响： Union County (United States (USA))   其它: 50% of Toronto's street trees are maples - one of the beetle's preferred host species. These and other threatened hardwoods provide shade and beauty, shelter birds and animals, help filter air pollutants, produce oxygen, and increase property values. 生态系统变化: Broad-leaved deciduous trees are a vital component of healthy woodlands in southern Canada. Many of Canada's endangered and threatened species are found in Ontario hardwood forests. Forest health and biodiversity are at stake. 经济 /民生: Canada's commercial hardwood forests produce $11 billion in wood products annually. The maple syrup industry is worth another $100 million each year. Healthy forests also support tourism and recreation.
