为了阐明赤松挥发物对松材线虫离开松墨天牛成虫的时间模式（线虫离开曲线）的影响，将高压灭菌或正常的松树枝条提供给甲虫。单萜类化合物没有检测到从空气中的饲养容器与高压灭菌松枝。Kolmogorov-Smirnov检验表明，在不同食物条件下，2个甲虫种群的平均线虫偏离曲线存在显著差异。50%的线虫离开的时间是短的甲虫与高压灭菌的树枝。在51日龄时，线虫在体内的残留比例为：松墨天牛在供应高压灭菌的松枝的甲虫中显著较小。因此，建议B. xylophilus具有自发离开M.松墨天牛枝条的挥发性物质抑制了B。xylophilus从M.松墨天牛
To clarify the effect of the volatiles of Pinus densiflora on the temporal pattern of departure of Bursaphelenchus xylophilus from Monochamus alternatus adults (nematode departure curve), autoclaved or normal pine twigs were provided to the beetles. Monoterpenoids were not detected from the air of rearing containers with autoclaved pine twigs. A Kolmogorov-Smirnov test showed that there were significant differences in the averaged nematode departure curve between the 2 beetle groups supplied with different foods. The time of 50% nematode departure was shorter in the beetles supplied with autoclaved twigs. The proportion of nematodes which remained in the bodies of 51-day-old M. alternatus was significantly smaller in the beetles supplied with autoclaved pine twigs. Consequently, it is suggested that B. xylophilus had a trait of spontaneous departure from M. alternatus and that the volatiles from excised normal P. densiflora twigs repressed B. xylophilus departure from M. alternatus.
