Abstract Interfertile populations of the seed beetle Callosobruchus maculatus differ genetically in several behavioral, morphological, and life‐history traits, including traits that affect the intensity of larval competition within seeds. Previous studies have suggested that this variation depends on differences in host size. I performed a selection experiment in which replicate beetle lines were either maintained on a small, ancestral host (mung bean) or switched to a larger, novel host… Expand
