1.Protozoa and nematodes are important microfauna predators in soil and compete for the same food resource, bacteria. Therefore, inhibition of competitors may enhance food acquisition and fitness of individual predator species.2.We investigated chemical based interference between the nematodeCaenorhabditis elegansand the amoebaAcanthamoeba castellaniiin a bacteria‐free gnotobiotic system.3.Exoproducts of amoebae exhibited marked nematostatic activity, and repelled the worms. However, nematodes were able to reduce the activity of proteases and glycosidases, two enzymes playing an important role in the toxicity ofA. castellanii. Exoproducts of nematodes also detrimentally affected amoebae by reducing growth and increasing encystation.4.The results indicate that both protozoa and nematodes can inhibit each other, and that nematodes are also able to counteract the attack by protist competitors. Non‐trophic interactions appear thus as a new factor affecting the structure of predator communities in soil.
