Abstract

Differential nutritional suitabilities of the 12 potential host plants of Papilio canadensis in the Great Lakes region of North America were determined with gravimetric techniques for penultimate and final larval instars. While leaf water content and leaf nitrogen content explain some of the variation, allelochemicals in different plants are likely to be involved in differential larval growth performances as well as mortal- ity of neonate larvae on tuliptree and spicebush. Oviposition tests using 3-choice arenas with quaking aspen, paper birch, and balsam poplar showed no strong host preferences. Factors affecting patterns of Papilio host use in the Great Lakes region are discussed.
