As the gypsy moth expands its range into new portions of the United States, there is a need to predict which tree species will be attacked by this defoliating insect. There have been several studies describing feeding preferences of the gypsy moth, but these results have not been summarized in a single list. We report and summarize all of the major tests of foliage suitability to gypsy moth for tree species found in the United States. Foliage suitability to gypsy moth is a trait that is correlated among closely related species. As a result, it is possible to extrapolate foliage suitability of North American tree species for which no screenings have been performed. A list of suitability is summarized as susceptible, resistant, or immune.
