INTRODUCTION
In light of a decade of discussion about tritrophic interactions and the effects of natural enemies on plants and invertebrate herbivores (e.g., Price et al. 1980, Duffey et al. 1986, Price 1986, Bernays and Graham 1988, Hay et al. 1989, Kareiva and Sahakian 1990), it is surprising how little is known about the actual utility of putative antipredator mechanisms found in herbivores. There are many good studies documenting chemical, behavioral, and morphological defenses that herbivores use against natural enemies (reviewed by Witz 1990), but many of these studies do not examine how the defense actually functions against a predator. Rather, they simply ...
