Abstract: Bethylid (Scleroderma sp.) is one of the ectoparasitic wasp species that infest the larvae and pupae of Semanotus bifasciatus (Motsch.) Its adult over winters in a bored hole of tree trunk. Under room temperature, five to six generations of adults can be reared annually. Monochamus alternatus Hope and Callidicum villosulm Fairm. may be used as culture hosts for artificial propagation of Scleroderma sp.. This bethylid has an ability to bore into the wood of tree trunk to search for its host. It is released to control the larvae of Semanotus bifasciatus (motsch.) in China fir (Cunninghamia lanceolata) stands, the rate of parasitization is about 70%.
