Results of no-choice feeding bioassays determined adult Japanese beetles feeding on North American elms of U. alata and U. americana removed nearly twice as much leaf tissue in comparison to U. thomasii (Table 2). Collectively, for the 45 other Ulmus taxa or cultivars tested, only 10 had less feeding than U. thomasii (Table 2). Percent field defoliation survey results (Table 4) coincided with no-choice laboratory tests.
