Mountain Lake Biological Station, University of Virginia, Charlottesville, Virginia, USA 22901 PERFORMANCE OF A WILLOW-FEEDING BEETLE, CHRYSOMELA KNABI BROWN, AS AFFECTED BY HOST SPECIES AND DIETARY MOISTURE [Elektronische Daten] [David R. Horton] Larval performance and adult size of Chrysomela knabi Brown varied with host quality and species. Beetles reared on a low moisture diet of Salix humilis Marsh. or a novel host, S. nigra Marsh., showed reduced growth rates, survival, and adult size compared with performance on the local host, S. humilis, at high moisture. For all performance variables, beetles were least successful on the novel host. Development (hatch to pupation) was 1.2 and 3.9 days faster on the high moisture diet than on the low moisture diet or novel host, respectively. Survival (hatch to pupation) was 8 and 20% higher on the local host (high moisture) than on the low moisture diet and novel host, respectively. Weight and elytral length of newly eclosed adults showed these same trends.
