Abstract
Female oviposition preference and larval performance of Malacosoma americanum, the eastern tent caterpillar, were investigated in field and laboratory studies. A simple hypothesis states that the adult female oviposits on a host because it will be best for her offspring in terms of growth and survivorship. Statistical analyses show that the preferred host species for oviposition is Prunus serotina while larval growth is highest on a non-host tree, Populus tremuloides. The original hypothesis is rejected by this study. Alternative interpretations for the discrepancy concerning female oviposition preference and larval performance are suggested.Subjects
