摘　　要：双条杉天牛主要危害10a生以上树势衰弱的侧柏，在侧柏树上主要分布高度为0～2m，在侧柏林内空间分布型呈聚集分布。其发生与坡向、坡位有明显关系，阳坡〉阴坡，中坡〉下坡〉上坡。人为活动影响双条杉天牛的发生，天敌对双条杉天牛有明显控制作用。提出了检疫、营林、饵木诱杀、干基打孔、保护天敌等防治技术措施。Semanotus bifasciatus mainly attacked weak Platycladus orientalis trees, It distributed in the trees at the height between 0 and 2 m and the spatial pattern was aggregated dispersion. The occurrence of the pest was correlated with the aspect and position of the slope as well as human activity, Natural enemies played a good role in the control of the pest, Control measures such as quarantine, silvicultural management, bait wood trap, trunk injection and natural enemy protection were suggested,
