Ophiostoma ips from Pinewood Nematode Vector, Japanese Pine Sawyer Beetle (Monochamus alternatus), in Korea

摘要

Japanese pine sawyer beetle ( Monochamus alternatus ) is an economically important pest in coniferous trees. Ophiostoma ips was isolated from the beetle and identified based on analysis of morphological properties and the β-tubulin gene sequence. The fungus easily produced perithecia with a long neck on malt extract agar and its ascospores were rectangular shaped. This is first report of Ophiostoma species associated with the pinewood nematode vector beetle in Korea.
