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.
Abstract
Selected elm, Ulmus spp., and their hybrids growing at The Morton Arboretum, Lisle, IL, were evaluated in bioassays for feeding preference by the Japanese beetle, Popillia japonica Newman. No-choice bioassays revealed that the hybrids U. ‘Morton’-Accolade (U. japonica x U. wilsoniana),U. elongata, U. laciniata, U. lamellosa, U. macrocarpa, U. parvifolia, U. ‘Morton Plainsman’-Vanguard (U. japonica x U. pumila) x U. davidiana, and U. Morton Plainsman-Vanguard (U. japonica x U. pumila) x U. japonica-wilsoniana-pumila had low (,31%) amounts of leaf tissue consumed. The hybrids U. davidiana x U. japonica, U. davidiana x U. japonica-wilsoniana-pumila, and U. japonica had high (.68%) amounts of leaf tissue consumed. Rankings for the dried fecal pellet weights, field defoliation survey, and multiple-choice studies were consistent with the no-choice studies for thesesame elm genotypes. Leaf pubescence on U. glaucescens, U. lamellosa ,and U. macrocarpa seems to be a feeding deterrent for the adult beetle as evidenced by low levels of feeding damage (,26%)in the laboratory studies, low dried fecal pellet weights (,24 mg), and field defoliation ratings noto very light feeding (,0.6). The genotypes of U.Morton-Accolade (U. japonica x U. wilsoniana),U. elongata, U. laciniata, U. lamellosa, U. macrocarpa, U. parvifolia, U. Morton Plainsman-Vanguard (U. japonica x U. pumila) x U. davidiana, and U. Morton Plainsman-Vanguard (U. japonica x U. pumila) x U. japonica-wilsoniana-pumila show promise for use for future elm breeding programs
