In a recent TREE article , we identified three categories of unintended indirect effects that can arise from host-specific biological control agents: (i) ecological replacement; (ii) compensatory responses; and (iii) food-web interactions. Although our review focused on the biocontrol of plant pests, we suggested these concepts also apply to the biocontrol of invertebrate pests. Thomas et al.  argue that our treatment of ecological replacement was unjustified and that indirect effects owing to compensatory responses and food-web subsidies do not apply to biocontrol of invertebrate pests.
