Title: Taste sensitivity of the cotton leafworm, Spodoptera littoralis, to chemicals
Abstract: Abstract Threshold values of acceptance and rejection for 16 sugars and 12 electrolytes were measured. Most pentoses, hexoses, di- and tri-saccharides are stimulating. Compounds with α-linkage are superior stimuli. Substitution in the sugar molecule causes an obvious change in its stimulating characteristic. The rejection thresholds of the larvae to electrolytes showed a higher stimulating effectiveness for either acids or hydroxides than for neutral inorganic salts. The cations in a uniform anion combination stimulated in an order which was mostly correlated to their ionic mobilities. The stimulating efficiency of aliphatic alcohols was found to increase with the increase of molecular weight. An inverse relation was found between the stimulating efficiency and the vapour pressure of the alcohols tested. The line describing the relation between the rejection thresholds and the chain length of alcohols showed an inflection near butanol with a molecular weight of 74.
