松木线虫（Bursaphelenchus xylophilus）能够在短时间内产生数十万个后代。它的交配行为可能在这种显著的繁殖力中发挥了基本作用。采用长时间显微镜录像和反复观察的方法，研究了嗜木蛾的交配行为特征。木褐蝽的交配行为可分为巡航、接近、相遇、接触、环抱、定位、依附、射精、分离、静止和漫游等一系列连续的子行为。总的来说，交配行为的过程可以分为四个不同的阶段：寻找、接触、交配和徘徊；不同阶段的平均时间差异显著，分别为21.8±2.0 min、28.0±1.9 min、23.6±0.7 min和7.2±0.5 min。结果表明，性信息素可能参与了嗜木小蠊的交配行为。此外，当一只雌性与三只雄性放在一起时，观察到雄性与雄性之间的竞争，这可能是由雌性的交配选择压力引起的。雌性的性内竞争也偶尔被观察到。
The pine wood nematode (PWN), Bursaphelenchus xylophilus, is able to produce hundreds of thousands of offspring in a short time. Its mating behaviour might play a basic role in this marked fecundity. We investigated the features of the mating behaviour of B. xylophilus using long-time microscope video and repeated observations. The mating behaviour of B. xylophilus could be separated into a series of sequential sub-behaviours, including cruising, approaching, encountering, touching, hooping, locating, attaching, ejaculating, separating, quiescence and roaming. Overall, the process of mating behaviour could be divided into four different phases, searching, contacting, copulating and lingering; the mean times for these different phases varied significantly with 21.8 ± 2.0 min, 28.0 ± 1.9 min, 23.6 ± 0.7 min and 7.2 ± 0.5 min for each of the four phases, respectively. Attraction between the sexes was observed, indicating that sex pheromone(s) might be involved in mating behaviour of B. xylophilus. In addition, when one female was placed with three males, male-male competition was observed, which might be caused by mating-choice pressure from the female. Intra-sexual competition of females was also occasionally observed.
