Because variation in host quality and levels of intraspecific competition have been shown to affect growth, survival, and fecundity in a large number of parasitoid and obligate internally feeding granivore species, it is expected that selection will favour those females that are able to discriminate among potential hosts. Previous studies on the bruchid beetle Callosobruchus maculatus (F.) have shown that females lay more eggs on large seeds than small seeds. These studies, however, have typically presented females of a single strain with seeds that differed markedly in size. Here, we test the ability of females of two strains, which differ in their larval competition strategies, to discriminate among incremental levels of “small ” versus “...
