Fig. 3.

Percentage of Cotesia glomerata cocoon clutches that contained hyperparasitoids in the field trials either at the plant level (i.e., at least one cocoon clutch out of the five clutches attached to the plant yielded hyperparasitoids) (left) or at the individual clutch level (right). The cocoons were collected from plants that were either left untreated (UD), infested with unparasitized Pieris caterpillars (UNPAR) or parasitized by C. glomerata (CG), C. rubecula (CR) or Hyposoter ebeninus (HE). Dark green bars indicate plant treatments with P. brassicae caterpillars; light green bars indicate treatments with P. rapae caterpillars, white bars indicate undamaged plants. Letters indicate significant differences between treatment groups (GLM, P < 0.05)
