Per BugGuide: "Larvae are a major mortality agent of stressed oaks (Quercus), particularly red oaks (Muzika et al. 2000); adults feed on chestnut blight spores (Cryphonectria parasitica)." Also: "Substantial injury and mortality of American chestnut caused by A. bilineatus was noted as early as 1891; A. bilineatus was purportedly responsible for the death of 75% of the chestnut trees in Fairfax County, VA in 1893. Although largely ignored in the intervening decades, the beetle has been documented as a cause of oak mortality. (Muzika et al. 2000)" (More at BugGuide).
