Wildfire is an important disturbance factor in forest ecosystem and could affect the distribution of insects. Because Monochamus beetles are known vector insects of pine wood nematodes in Korea and burnt pine trees can be used as oviposition habitats for Monochamus beetles, we investigated changes in the spatial (among fire severity classes) and temporal (between years) distributions of M. alternatus and M. saltuarius. From late May 2017 to early October 2018, four multi-funnel traps with pheromone lure were installed in each fire severity class (unburned, light, light-moderate edge, moderate-severe edge, and severe). All traps were replaced fortnightly from May to October for two years. The spatial distribution of the two Monochamus beetles was significantly affected by fire severity. In particular, M. alternatus showed higher catches in the severely burned sites and responded positively to the fire. A similar number of M. saltuarius individuals were observed between 2017 and 2018, while more M. alternatus were caught in 2018 compared to 2017. Consequently, it was confirmed that the dead wood of P. densiflora caused by the wildfire had a great influence on the density of insects, especially M. alternatus.

野火是森林生态系统中的重要干扰因素，可能会影响昆虫的分布。由于松墨天牛甲虫是韩国已知的松木线虫的媒介昆虫，并且可以将烧毁的松树用作松墨天牛甲虫的产卵生境，因此我们研究了松墨天牛的空间分布（在火灾严重性类别中）和时间分布（年间）。和M. saltuarius。从2017年5月下旬至2018年10月上旬，每个火灾严重程度级别（未燃，轻，中度边缘，中度-重度边缘和严重）均安装了四个具有信息素诱饵的多漏斗陷阱。从5月到10月每两周更换一次陷阱，为期两年。两者的空间分布松香天牛甲虫受火势严重影响。特别是，在严重烧毁的地方，松墨天牛表现出较高的捕获量，并对火势有积极反应。类似数目M. saltuarius 2017年和2018年间观察到个人，而更多的松褐天牛是在2018年陷入比2017年因此，可以确认的枯木赤松由野火造成了很大的影响昆虫的密度，尤其是互生分枝杆菌。
