There are two principal native host plants for the sphingid moth Manduca sexta L. in south eastern Arizona: Datura wrightii (Solanaceae), and the more recently reported, nonsolanaceous host, Proboscidea parviflora (Martyniaceae). A comparative study on causes and rates of mortality was conducted, since this provided a “natural experiment” for examining potential trade-offs in host use. The field data identified a dramatic trade-off between plant quality and predation. D. wrightii appears to… CONTINUE READING
