Abstract
The physiological effects of two phenolic nematocides, chavicol and de methyleugenol, on C. elegans were studied by [Ca2+](i) measurement usi ng a microspectrofluorometer and an image analyzer. Chavicol and demet hyleugenol, which had similar effects on the nematodes, caused a signi ficant elevation of [Ca2+](i) in the intestinal tract. The image analy sis suggested that these phenolic nematocides caused the destruction o f cell membrane and the leakage of cytosol from the intestinal tract i nto the pseudocoelomic cavity.
