AbstractWe assessed the robustness of a standard classification of foliage suitability of North American tree species to the gypsy moth (Lymantria dispar L.) for tree species of southern Quebec grown under contrasting water regimes. Dispersal trials for 1st-instar larvae and feeding trials for 4th-instar larvae were conducted to determine whether water regime and (or) maternal effects influenced the preference or avoidance of gypsy moth larvae for foliage from saplings of native tree species of Quebec. We found no effect of water regime on the suitability of foliage to 1st-instar larvae and no effect of water regime and maternal effects for 4th-instar larvae. The standard classification scheme used by U.S. Department of Agriculture researchers in the United States was generally robust to the above factors, and thus suitable for use in southern Quebec.
