The magnitude of inbreeding depression (δ) for adult lifespan of two populations of Callosobruchus maculatus reared at four temperatures. (a) δ For lifespan before correcting for effects of body mass. (b) δ Is least square means after removing the effect of inbreeding on adult body mass; note that the pattern changes little. δ Was calculated for each block, and then averaged across blocks; note that both δ and L for males are ∼0 (and substantially less than females) when reared at 25 °C, but much greater than 0 (and not less than females) when reared at 20 °C.
