摘要: In insects with sex role reversal in mating, which females actively court males, large and nutritious ejaculates are a common direct benefit to females. Such costly for males produce their size composition can depend on male condition. However, the fitness effects of such condition-dependent provisioning less clear. Here, we studied phenotypic condition mating behaviour, ejaculate reproductive output honeylocust beetles, Megabruchidius dorsalis. Our experimental design allowed us disentangle independent juvenile resource acquisition both sexes (as reflected by body size) adult (feeding). We show that had sizeable interactive output. resources accrued during phase significant but relatively marginal reproduction. Male feeding, contrast, almost all aspects female reproduction, through nutritional discuss our findings light roles sexual dimorphism exhibited this species, relative related species. results highlight importance testing interaction components understand evolution maintenance systems.
