Abstract
The influence of oviposition substrate on female receptivity to remating is examined in Callosobruchus maculatus (F.) by comparing responses of nonvirgin females, maintained with or without access to oviposition substrate, to subsequent courting males. We demonstrate that females maintained without oviposition substrate, and thus prevented from ovipositing, readily reject additional male attempts to copulate. Females allowed unrestricted access to oviposition substrate, on the other hand, remate readily with subsequent courting males. These treatment differences are not the result of differences in male behavior; males responded similarly to females in each treatment. We then discuss four hypotheses which may explain these observed treatment differences.
