Fungi associated with the beetles of Ips typographus on Norway spruce in southern Poland

The mycobiota of the beetles of the phloem-feeding spruce bark beetle, Ips typographus was studied. The most important group of fungi were the ophiostomatoid fungi. Among them O. penicillatum was very frequent ophiostomatoid species. Other common fungi were O. ainoae, O. bicolor, O. piceaperdum and O. piceae. The ophiostomatoid fungi were often more frequent in beetles collected in galleries than in the beetles caught With a trap. Generally the ophiostomatoid fungi were more ofien isolated from the beetle.s bathed in sterile water for 30 seconds. However C. polonica, O. ainoae, and O. minutum occurred most abundantly in the beetles disinfected in 96% ethyl alcohol for 15 and 30 seconds.
