Fitness correlates (development time and mass) of the herbivore Mamestra brassicae (a, b) and its parasitoid Microplitis mediator (c, d) when they were reared on cultivated (CYR or STH) or wild (KIM, OH, WIN) cabbage (Brassica oleracea). Hosts (healthy or parasitized) were reared in Petri dishes and provided with leaf tissues collected from non-induced plants (open bars) or from plants that had been exposed to Pieris rapae feeding for 7 d (hatched bars). Leaf tissues were replaced every other day. Parasitoids data are given for males (grey or hatched grey bars) and females (white or hatched white bars) separately. Bars are the mean values (+SE) based on pooled data per dish
