Title: Response to Thomas et al.: Biocontrol and indirect effects

Author: Pearson, Dean E.; Callaway, Ragan M.;

Date: 2004

Source: Trends in Ecology and Evolution. 19(2): 62-63.

Publication Series: Scientific Journal (JRNL)

Description:

In a recent TREE article [1], 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. [2] 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.

Keywords: biological control agents, pests
