      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.

The unique type of wilting disease, black-stain root disease, spread by root-feeding insects and caused by the fungus Lepfographilll7l wageneri (Kendrick) Wingfield has limited occurrence in Europe compared to Western North America .
