INTRODUCTION
Although relatively few freshwater invertebrates appear to feed on live aquatic macrophytes, when these plants senesce or die, they are rapidly consumed and contribute substantially to the food base of aquatic systems (Newman 1991). Several authors have suggested that this low utilization of live plants may be due to their possession of chemical feeding deterrents which inhibit their consumption by aquatic invertebrates (e.g., Otto and Svensson 1981, Ostrofsky and Zettler 1986, Kerfoot 1989, Suren 1989; see reviews by Lodge 1991 and Newman 1991). However, there are few freshwater studies that link feeding response to specific chemicals.
