We are testing the roles of root colonizing beetles and Leptographium associates in predisposing trees to Ips. During , we placed primary emphasis on spatially explicit statistical approaches, mark-recapture experiments to evaluate the role of dispersal in predator-prey interactions and relationships of tree defense physiology and chemistry. Insects can disseminate spores of the fungus that causes black stain root disease to the fire‐weakened trees they attack (Safranyik et al., ); the disease is a potentially lethal disorder caused by Leptographium wageneri (Kendrick) by:
Leptographium wageneri (Kendrick) Wingfield, which cause black stain root disease of conifers, have led to severe losses in the United States and Canada (Wagener & Mielke, ; Cobb, ; Harrington, a). Some Ceratoc;ystis spp. can also cause serious tree diseases. Ceratocystis fimbriata Ellis & Halstead causes canker on.

terebrans have only been the focus of a few studies, primarily in relation to its association with root disease in the southern USA (Eckhardt et al., ).Overall, evidence indicates that this beetle has no consistent. Leptographium spp. are commonly associated with bark beetles and weevils (Coleoptera: Curculionidae), and some are important tree pathogens.

When conifers such as Chinese white pine (Pinus armandi Fr.) are attacked by insects or pathogens, they respond by increasing their content of monoterpenes and sesquiterpenes. In this study, we determined the effects of the blue-stain fungus Leptographium qinlingensis Tang and Chen on monoterpenes and sesquiterpenes in the phloem and xylem of the stem of P.
