　　蠹虫遍布我国南北各省区，为害马尾松、赤松、华山松、油松、樟子松、黑松等。以成虫和幼虫蛀害松树嫩梢、枝干或伐倒木。凡被害梢头，易被风吹折断。该虫在广州白云山景区为害马尾松甚烈。
　　形 态 特 征 松纵坑切梢小蠹属鞘翅目，小蠹虫科。成虫体长3.5~4.5毫米，椭圆形，全体黑褐或黑色，具光泽密布刻点和灰黄色茸毛。头部半球形，黑褐色，额中央有一纵隆线；复眼卵圆形、黑色；触角黄褐色，端部膨大呈锤状。前胸背板近梯形，前狭后宽。鞘翅棕褐色，基部与端部的宽度相似，长约为宽的3倍，其上有由刻点组成的明显行列，斜面上第二列间部凹陷，小瘤和茸毛消失，雄虫较雌虫显著。卵淡白色、椭圆形。幼虫体长5~6毫米，乳白色，无腹足，体粗壮多皱纹、微弯曲。蛹为裸蛹，长约4.5毫米，白色。
　　生 活 史 及 主 要 习 性 每年发生1代，以成虫越冬，越冬场所南北方各异。在南方，成虫在被害枝梢内越冬。越冬成虫于翌年3月下旬到4月中旬离开越冬处，侵入松枝梢头髓部进行补充营养，以后在健康的树梢、衰弱树或新伐倒的树木上筑坑、交配、产卵。在杭州观察，卵于4月中旬孵化，幼虫孵出后即行蛀食为害，形成坑道，坑道为单纵坑，在树皮下层，微触及边材，坑道长一般为5~6厘米，子坑道在母坑道两侧，与母坑道垂直，长而弯曲，通常10~15条。幼虫期约1个月。5月中旬化蛹，蛹室位于子坑道的末端。5月下旬到6月上旬出现新成虫，再侵入新梢进行补充营养。成虫在梢枝上蛀入一定距离后随即退出，另蛀新孔，在1条枝梢上侵入孔可多达14个。
