松材线虫Monochamus ternatus Hope(鞘翅目：天牛科)是通过传播松材线虫松材线虫而危害松树的一种重要害虫。2013年至2015年在广东(中国)进行了现场研究，以评价商业引诱剂的效果、诱捕器放置对松墨天牛的监测效果以及诱捕器捕获的时间格局。为了监测松墨天牛，对4种商业引诱剂、3个诱捕地点(离地面0、1.5和3m)和不同诱捕距离(50、200、400、600和900m)进行了评估。以单氯酚和植物挥发物混合为诱饵的诱捕器比单独使用单氯酚或植物挥发物的诱捕器捕获的甲虫要多得多。在距地面1.5m处设置的诱捕器捕获松墨天牛的数量显著多于在0m和3m处设置的诱捕器。根据2013年和2014年在两个地点捕获的2687只甲虫的数据，雌雄比例为2.9-4.1：1。根据设置在距离森林边缘不同距离的陷阱，甲虫的自然扩散距离约为100米。38wk以上的连续监测表明，松墨天牛成虫的羽化高峰期为一年内的5~6月。
The pine sawyer beetle, Monochamus alternatus Hope (Coleoptera: Cerambycidae) is a serious insect pest of pine trees by vectoring the pine wood nematode, Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle (Nematoda: Aphelenchoididae). Field studies were carried out during 2013-2015 in Guangdong (China) to evaluate the effectiveness of commercial attractants, effect of trap placement for monitoring M. alternatus, and temporal patterns of trap catch. Four commercial attractants, three trap placements (0, 1.5, and 3 m above ground) and different trapping distances (50, 200, 400, 600, and 900 m) from forest edge were evaluated for monitoring M. alternatus. Traps baited with a mixture of monochamol and plant volatiles captured significantly more beetles than traps baited with monochamol alone or plant volatiles alone. Traps set up at 1.5 m above the ground captured significantly more M. alternatus than those at 0 m and 3 m height. Based on 2,687 beetles trapped from two locations in 2013 and 2014, the female: male ratio was 2.9-4.1:1. The beetles' natural dispersal distance was approximately 100 m based on traps set at different distances from edge of the forest. Continuous monitoring over 38-wk period indicates the peak of adult M. alternatus emergence was between May and June within a year.
