Abstract

Two common laboratory organisms, Caenorhabditis elegans and Daphnia pulex, were exposed to pulverized mixtures of water and adult Plecia nearctica Hardy 1940, for the purpose of toxicity testing. No toxicity was observed, and the pulverized insects were actually the preferred food source for the C elegans. This brief test gave no indication that P nearctica contain toxins to discourage natural predation as is commonly thought.
