dc.descriptionTwo species of the genus Monochamus (Coleoptera: Cerambycidae), M. alternatus and M. saltuarius are well-known as vectors of the pine wilt disease and they causes economically damages in South Korea. Among various control methods to reduce the density of vectors, a method by biological control agents (natural enemies) is eco-friendly indispensable. Since 2017, we have carried out the studies on the parasitic natural enemies againt for the vector species and found two parasitoids, Spathius verustus Chao, 1977 (Braconidae) and Cyanopterus flavator (Fabricius, 1793) (Bracondiae), would be a useful agents for biological controls. For accumulation of biological data, we conducted a preliminary study on life span and parasitic rate of two parasitic wasps against for two vector species. As results, we found that S. verustus has the longest adult life span of 33.4±19.2 days (avg.) in M. alternatus (T=30°C, H=60%) and C. flavator has the longest adult life span of 25.1±10.6 days (avg.) in M. alternatus (T=25°C, H=60%). The average parasitic rate (62.5%) of S. verustus was highest in M. alternatus (T=30°C, H=60%). In addition, it is confirmed that the offsprings of S. verustus can be made by parthenogenetic reproducton. Keywords: Research ID: 3622037
