Abstract
Although shiitake sawdust-block cultivation has become popular, it has been accompanied by pest damage. Currently, although cultivation facilities have been disinfected using adhesive sheets or light traps, further extermination methods are in demand from problems about disposal labor time and environmental health. In this study, in order to find fungi suitable as biological control agents, we investigated the fungi isolated from harmful flying insects in shiitake cultivation facilities. As a result, 37 of 52 strains were identified as Lecanicillium spp., and others were parasitic fungi belonging to the Ophiocordycipitaceae and Cordycipitaceae except for one strain. In addition, a tendency for the species of entomogenous fungi to differ depending on the method of shiitake cultivation was observed.
