Monochamus saltuarius Gebler (Coleoptera: Cerambycidae) is a well-known as vector species of the pine wood nematode (PWN) in the northern areas of South Korea. In 2017, larval parasitoids of M. saltuarius and their parasitism patterns were investigated in Pinus koraiensis forests with consideration of sentinel logs positions (height: 0 m vs. 1.8 m), distances from the edge to the center of the forest (0, 20, 40, 60, 80m), and damage degrees of the pine wilt disease (infested area, buffer area, and uninfested area). In total six of larval parasitoids were collected: Spathius verustus, Sclerodermus harmandi, Cynopterus flavator, Heydenia testacea, Heydenia sp., Braconidae sp. The parasitism rate to larvae of M. saltuarius larvae was not affected by sentinel log positions. However, the parasitism rate was significantly higher in infested areas compared to the buffer and uninfested areas. In the infested area, the parasitism rate was increased with distance from forest edges.
