The effect of 21 amino acids on the feeding response of larvae of Spodoptera littoralis was investigated using the “Styropor method.” Lamellae of Styropor were treated a with different concentrations of amino acids, b different concentrations of amino acids mixed with 0.125 M sucrose, and c 0.125 M sucrose alone. The weight of Styropor consumed during 48 h served as the criterion of phagostimulation or phagodeterrency. With the sole exception of 0.125 M L-glutamic acid, no phagostimulation occurred in any of the amino acids tested in mixture with 0.125 M sucrose; none was phagostimulant when tested alone. Deterrency was found at 0.125 M in L-alanine, DL-alpha-amino- n-butyric acid, L-serine, L-cystine, L-methionine, L-tyrosine, and L-histidine, when mixed with an equimolar concentration of sucrose. Methionine was highly phagodeterrent also at 0.0625 M and, as was DL-alpha-amino-n-butyric acid, still active even at 0.0125 M. Chemical analysis showed that there was no decomposition of methionine applied on Styropor. © 1976, Springer Science + Business Media B.V.. All rights reserved.
