Abstract--We examined the interaction between host trees and fungi asso-
ciated with a tree-killing bark beetle, Dendroctonus frontalis. We evaluated
(1) the response of four Pinus species to fungal invasion and (2) the effects
of plant secondary metabolites on primary growth of and secondary coloniza-
tion of three consistent fungal associates. Two of these fungi, Entomocorticium
sp. A and Ophiostoma ranaculosum, are obligate mutualists with D. frontalis,
