Abstract

Spores characteristic of the tree pathogenic blue-stain fungus, Ophiostoma polonicum Siemasko, and other fungi are visible in scanning electron micrographs of pits on the pronotum and elytra of Ips typographus (L.). Inoculation and reisolation experiments showed that O. polonicum was transmitted to logs of generally higher frequencies by live beetles and their excised parts (head, prothorax, or elytra) than by the digestive tract. Other associated fungi isolated at high frequencies from I . typographus were O. bicolor Davidson Wells, O. penicillatum (Grosmann) Siemasko, Graphium sp., and yeasts.
