通过在松枝上笼住线虫侵染的甲虫24小时，研究了松材线虫通过卡林墨天牛取食伤口向成熟的田间生长的苏格兰松的传播。线虫传播到64个分支中的31个。成功传播的频率是独立的性别的甲虫，但依赖于甲虫的年龄。成虫出现后2、3、4周，甲虫的传播频率最高。每分支传播的线虫数量很低，甲虫性别或甲虫年龄类别之间没有差异。每分支提取的线虫数与每只甲虫携带的线虫数相关，但与分支上的取食面积不相关。
Transmission of pinewood nematode, Bursaphelenchus xylophilus, to mature, field grown Scots pines through feeding wounds of Monochamus carolinensis was investigated by caging nematode-infested beetles on pine branches for 24 hours. Nematodes were transmitted to 31 of 64 branches. Frequency of successful transmission was independent of the sex of the beetle but dependent upon beetle age. Transmission frequencies were highest for beetles 2, 3, and 4 weeks after emergence as adults. The number of nematodes transmitted per branch was low and did not differ between beetle sexes or among beetle age categories. The number of nematodes extracted per branch was correlated with the number of nematodes carried per beetle but was not correlated with the feeding area on the branch.
