Abstract
The labial gland of the French subterranean termite Reticulitermes santonensis De Feytaud contains a polar. heat-resistant, and persistent chemical signal that is released onto the Food during food exploitation and stimulates feeding in nestmates. Separation of the labial gland secretion by thin-layer chromatography on cellulose plates revealed that the secretion contains components with reducing and amino groups, In feeding bioassays conducted on the cellulose plate after TLC, termites preferred the area between R-f 0.46 and 0.88 (biologically active zone) for feeding; indicating the location of the feeding-stimulating signal, Thirty-live synthetic chemicals with similar chemical properties as the feeding-stimulating signal were analyzed with TLC. None of them covered the biologically active zone. Therefore, all chemical classes tested, such as sugars, amino acids. and salts, are unlikely as possible sources for the signal structure. In feeding choice tests with synthetic chemicals, termites showed clear feeding preference only for sugarlike components with physiologically excessive concentrations of 10 mmol and 100 mmol. Amino acids induced only light feeding preference. The intensity of feeding stimulation by the natural signal from the labial gland as compared to synthetic phagostimulants is discussed.
