O. minus was proved to be a fungus associated with Tomicus piniperda and T. minor , exhibiting the positive correlation between beetle damage level and the fungal occurrence. The blue stain fungus in Yunnan was mainly isolated from Pinus yunnanensis , with a few isolations from P. densata and P. kesiya .展开更多

Among them,12 are saprophytes,10 facultative fungi and 8 parasites. Moreover,there is no obvious differentiation in the dominant populations including Debaryomyces,Penicillium and Paecilomyces with the damage level of localities and there exists no close interior relation between bark beetle attacks and dominant populations. Besides these,blue stain fungi which identified as Leptographium spp.were isolated from Tomicus piniperda and trunk tunnels.展开更多
