Evidence is accumulating that oak bark beetles. Pseudopityophthorus spp., are important vectors of the oak wilt fungus, Ceratocystis fagacearum. They make breeding attacks on nearly all wilt-injected trees, often in large numbers. Many parent adults, as well as their progeny, leave the diseased tree, and some are contaminated with propagules of the fungus. They readily feed on healthy oaks, making wounds that are ideal infection courts for the fungus. Infection does occur when contaminated beetles feed on healthy oaks.
