Academic – The early stages of fungal invasion in Norway spruce infested by the bark beetle Ips typographus

Abstract

Healthy Norway spruce trees infested by the bark beetle Ips typographus were investigated weekly for 10 weeks to examine the early stages in fungal invasion. The study was performed in southeastern Norway during an epidemic period. The fungal association consisted of Ophiostoma species and an undescribed Graphium species, which invaded the sapwood in an obvious succession. The pathogenic species Ophiostoma polonicum was the first invader of both phloem and sapwood and was always in the leading edge of fungal penetration into sapwood. Ophiostoma bicolor followed O. polonicum in the sapwood invasion. These species were successively replaced by Graphium sp. 1 , Ophiostoma pennicillatum and Ophiostoma ainoae. Ophiostoma pellicillatum seems to be more adapted to colonizing the phloem than the sapwood. The earliest invaders were the species most frequently carried by the beetles.
