Suitability and Feeding Preference of Selected North American, European, and Asian Elm (Ulmus spp.) Biotypes to Elm Leaf Beetle (Coleoptera: Chrysomelidae) (3.114644)
Date: September 2002Creator: Miller, Fredric D., Ware, George
Type: Article
Description:Journal of Environmental Horticulture. From the authors: "In this study, we report on the preference and suitability of 18 elm biotypes for elm leaf beetle larval development, and adult preference and suitability. The results presented here provide a more comprehensive data base of preference and suitability of North American, European, and Asian elm bio-types for the elm leaf beetle, and provide further direction for future elm breeding programs for resistance to elm leaf beetles and other leaf-feeding insect pests, eventually resulting in a reduction in the need for chemical pesticides."
