Ambrosia Beetles of the tribe Xyleborini attack stressed and dying trees and some species are problematic pests of nursery stock, and fruit and nut crops. it is common to find fungal and bacterial phytopathogens in and around ambrosia beetle galleries on attacked trees. This study examines the effect of phytopathogen infection on tissue ethanol content of apple trees and the relative attractiveness to attack by ambrosia beetles.
