Microbial Control of Bursaphelenchus xylophilus by Fungi

Abstract

To reduce the number of pinewood nematodes (Bursaphelenchus xylophilus) carried by the Japanese pine sawyer (Monochamus alternatus), we attempted to change the mycoflora and also to prevent blue-stain fungi, the main food-source fungi of the nematodes, from spreading throughout pine wilt-killed Pinus densiflora wood by inoculating other fungi into the dead logs. Trichoderma sp. 3 and Verticillium sp. inoculation treatments tended to decrease the number of the nematodes carried by the beetles.
