Abstract

<p>The effects of forest vegetation of the cultivation area of the shiitake mushrooms on the fungus gnat assemblages were investigated in Hita City, Oita Prefecture, Japan. The fungus gnat assemblages sampled in the indoor shiitake mushroom beds with sawdust-based artificial medium were also compared with those of the mushroom beds in the forests. Each a 100 m2 quadrat was established in the three indoor facilities, nine plantations of Japanese ceder and cypress (including three bed log laying yards), and eight broadleaf tree forests (including two bed log laying yards). The species and numbers of trees (DBH >50 mm, height >2 m), the volumes of the coarse wood debris, and the vegetation cover of the forest floors were recorded in the quadrats as the vegetation data. Fungus gnats were collected by six methods such as Malaise traps from October 2011 to December 2013. Non-metric Multidimensional Scaling based on the genera of the gnats suggested that their assemblages were different along with tree species assemblages and volume of the coarse wood debris. The abundance of Mycetophila ruficollis Meigen, a pest species of the shiitake mushrooms, in the bed log laying yards under Japanese ceder and cypress plantations was much higher than that in other forests. I supposed that the control measure for this pest species must be effective in the forests with the bed log laying yards. The forest stands with the tree uprootings must be watched as one of the habitats of Exechia shiitakevora Okada, which was frequently found on the uprootings.</p>
