Feeding Preference of Adult Japanese Beetles (Coleoptera:Scarabaeidae) for Asian Elm Species and Their Hybrids (3.100291)
Date: April 1999Creator: Miller, Fredric D.
Type: Article
Description:The objective of the described study was to conduct an initial screening of Asian elms and their hybrids for adult Japanese beetle feeding preference in the laboratory and in the field. The findings will contribute to selection and future potential of these elms, and provide a clearer direction for an ongoing comprehensive elm breeding program for Dutch elm disease, elm leaf beetle, and elm leaf miner resistance.

Feeding Preference for Selected Tilia Spp. and Cultivars by the Adult Japanese Beetle (Coleoptera: Scarabaeidae) (3.100292)
Date: May 1999Creator: Miller, Fredric D.
Type: Article
Description:The reported study was initiated to evaluate horticulturally desirable Tilia spp. for feeding preference by the adult Japanese beetle. A secondary objective of the study was to determine if leaf pubescence is a factor in feeding preference. Using mean percent leaf area consumed and mean dried fecal pellet weights as measures of susceptibility, the Asian species of T. petiolaris, T. oliveri, T.chinensis, and T. japonica show promise for partial resistance to Japanese beetles.

Resistance of Elms of the Ulmus davidiana Complex to Defoliation by the Adult Elm Leaf Beetle (Coleoptera: Chrysomelidae} (3.114634)
Date: October 1999Creator: Miller, Fredric D., Ware, George
Type: Article
Description:Journal of Economic Entomology: "[Study] objectives were to conduct an initial screening of members of the U. davidiana complex and their hybrids at The Morton Arboretum for suitability to the elm leaf beetle, to examine the genetic influence of U. propinqua, U. japonica, and U. davidiana parentage on suitability for elm leaf beetle, and to support the development of elm hybrids as part of a comprehensive breeding program for resistance to Dutch elm disease and the elm leaf beetle and the elm leaf miner."
