广西北海市白蚁对木结构的房屋为害比较普遍,达98%以上。除了白蚁为害以外,另一种对房屋建筑为害严重的是蛀木甲虫,主要是长甬凿点天牛 Strom-atium longicorne(Newmon)。此虫分布于两广,尤以海南、湛江、北科、钦州、防城等沿海一带受害最烈。主要在房屋建筑和家具木材中为害。蛀孔呈楠圆形,直径5～14毫米,内部坑道纵横交错,危害时发出“格——格”响亮的声音,外表完整无损,木里被蛀成粉末。粉末干燥,呈淡米黄色,
The termites of the Beihai City, Guangxi Province, are more prevalent in wood structures than in houses, accounting for more than 98%. In addition to termite damage, another serious damage to the house is the beech wood beetle, which is mainly Strom-atium longicorne (Newmon). This worm is distributed in Guangdong and Guangxi, especially in Hainan, Zhanjiang, North Branch, Qinzhou, Fangcheng and other coastal areas. It is mainly damaged in house construction and furniture wood. The hole is Nannan circular, with a diameter of 5 to 14 mm. The internal tunnels criss-cross. When the damage is made, a “quad-square” loud sound is emitted. The appearance is intact and the wood is crushed into powder. The powder is dry and pale yellow in color.
