松材线虫Bursaphelenchusxylophilus（B.木蠹蛾）是造成松树林毁灭性疾病的原因。其致病性与B个体数密切相关。木生植物雌性与雄性的比例（性别比例）是了解该物种种群变化的关键。B的性比。木虱种类繁多，但环境变化对木虱的影响尚不清楚。从野外不同样品中分离的线虫的性比在0.93和2.20之间变化。在实验室条件下，母体年龄和种群大小对子代性比无影响。从好到差的营养状况的变化与后代的性别比从1.85减少到1.41，这被推测是由于在初级性别比的变化。因此，B。随着母株年龄和种群数量的变化，木虱有效地维持了性比，但根据营养的变化调整后代的性比。
The pinewood nematode Bursaphelenchus xylophilus (B. xylophilus) is responsible for a devastating disease of pine forests. Its pathogenicity is closely related to the numbers of individual B. xylophilus. The ratio of female to male (sex ratio) is key to understanding population change in this species. The sex ratio of B. xylophilus varies widely, but it is unclear how it is affected by environmental changes. The sex ratios of nematodes, isolated from different samples in the wild, varied between 0.93 and 2.20. Under laboratory conditions, maternal age and the population did not affect the sex ratio of progeny. A change from good to poor nutritional status was associated with a reduction of the sex ratio of progeny from 1.85 to 1.41, which was speculated to result from a change in the primary sex ratio. Thus, B. xylophilus effectively maintains the sex ratio with maternal age and population changes but adjusts the sex ratio of progeny on the basis of the changes in nutrition.
