Presentation summary:
There has been a resurgence in severe defoliation by invasive Lepidoptera in recent years across northeastern hardwood forests. In particular, Lymantria dispar dispar (LDD) caused considerable forest damage in southern New England during 2015-2018 when multiple years of defoliation occurred in many stands. These defoliation events, coupled with drought conditions, led to extensive oak mortality in stands in Connecticut and Rhode Island. Defoliator trends in the northeast will be discussed, and stand-level data on the effects of LDD in Connecticut, Massachusetts, and Rhode Island will be provided.
