Siricid woodwasps and their fungal symbionts in Asia, specifically those occurring in Japan

Abstract

In Japan seven species of Siricinae have been recorded in four genera, namely Sirex, Urocerus, Xeris and Xoanon. The fungal symbionts of woodwasps in the genera of Sirex, Urocerus and Xoanon are all in the genera Amylostereum. We found that A. areolatum was carried by Sirex nitobei and Xoanon matsumurae, while A. laevigatum was the symbiont of Urocerus antennatus and U. japonicus in Japan. In this chapter, we present an overview of Siricid woodwasps and their fungal symbionts with a specific focus on those occurring in Japan.
