The relationship between blue-stain and bark beetles
1971 - IRG/WP 19
The attack of bark beetles on standing or in newly-felled stems provides special growth conditions to wood-inhabiting fungi. In the wood attacked by bark beetles, a specific and rich fungus flora is found, and from these fungi the economically important group of blueing fungi has been more thoroughly…
