Abstract: Oak leaftiers and oak leafrollers defoliate oaks throughout the northeastern United States and adjoining Canadian provinces. In recent years, scattered but severe outbreaks of oak Leaftier have occurred in Connecticut, Massachusetts, New Jersey, New York, Pennsylvania, and West Virginia. In 1978 more than 100,000 acres were defoliated in these states. Outbreaks of the oak leafroller complex have been reported in Michigan, Pennsylvania, and West Virginia.
