Abstract
The influence of nutrient chemicals on the feeding behavior of the larva of the Colorado potato beetle, Leptinotarsa decemlineata (Say), was investigated using an agar-medium assay. Twenty-six sugars, 27 amino acids, 9 vitamins, 2 sterols, 7 lipids, Wesson's salt mixture and its principal components were tested. One sugar (sucrose), several amino acids (L-alanine, γ-aminobutyric acid, L-serine, etc.) and 3 phospholipids (lecithin, phosphatidyl inositol, phosphatidyl L-serine) elicited marked feeding responses. Inorganic salts (KG, KH2PO4 and NaCl) were inactive alone but acted synergistically with other feeding stimulants. Additive effects on feeding responses were observed when 2 different feeding stimulants were combined. Three distinct types of joint action—additive, synergistic, and antagonistic—were recognized. These 3 types of interaction influence the feeding behavior of the potato beetle.This publication has 0 references indexed in Scilit:
