Arthropods and fungi beneath the bark of pine stumps were recorded 2-16 mo after tree felling at various locations in California. A succession of organisms was observed. Early colonizing arthropods wee potential candidates as vectors of Fomes annosus conidia. However the dominant insect Dendroctonus valens was observed with F. annosus only when the fungus had grown around the beetle, apparently killing it. Isolations from other arthropods collected from inoculated stumps failed to yield F. annosus, but Peniophora gigantea, an antagonist of F. annosus, was frequently obtained. Arthropods were observed among oidia of P. gigantea beneath the bark of 80% of the noninoculated ponderosa pine stumps.
