Abstract
Cold-water and hot-water extracts of flour made from germinating rye seed elicited a biting or feeding response from larvae of the prairie grain wireworm. Ethanol and petroleum ether extracts and the residue from the extractions did not. Solutions of L-alanine, L-asparagine, L-aspartic acid, DL-γ-aminobutyric acid, glycine, L-serine, L-threonine, L-tyrosine, or dextrose at a concentration of 0.020 M did not act as stimuli for the biting response. Similar concentrations of sucrose and fructose stimulated this reaction weakly. The results suggest that amino acids, polypeptides, or carbohydrates may be the causative agents for the biting or feeding response.
