Wildfire, which may effect on the spatial distribution of many insects, is one of important disturbances in forests. Because Monochamus beetles are known as vector insects of pine wood nematodes in Korea and burned pine trees can be used as oviposition habitats for Monochamus beetles, we investigated the changes in spatial and temporal distributions of M. alternatus and M. saltuarius across fire severity classes. We also studied other saproxylic beetles, such as cerambycid, scolytid, and bark beetles, which are potential insect pests for pine trees. Study area was classified by fire severity, such as unburned, light (<25% burned), moderate (25~75%), and severe (>75%). Spatial distribution of saproxylic beetles were significantly related to the fire severity.

In urban areas in Korea, cherry trees belonging to genus Prunus are one of abundant trees. In this study, damage rates and characteristics caused by Synanthedon bicingulata (Lepidoptera: Sesiidae) and Aromia bungii (Coleoptera: Cerambycidae) in cherry trees were investigated. Entrance holes of S. icingulata larvae were found from the most cherry trees planted along road-side verges irrespective of tree ages, while Entrance holes of A. bungii larvae were generally found from old trees above 30 cm in diameter at breast height, especially planted on dry environments, such as pavement roads, wood deck and so on.
