Abstract
1.
1. Dietary fatty acid fraction of larval faeces of Trogoderma granarium, containing palmitic, stearic, oleic and linoleic acids, induces and maintains the diapause in the larvae of the same species; linoleic acid is highly efficient either by feeding or by injection.
2.
2. A comparative examination of the fatty acid composition of diapause and nondiapause larvae of T. granarium showed that the diapause insects have an increased concentration of the bound myristoleic, palmitoleic and linoleic acids accompanied by a decrease in palmitic acid content.
3.
3. Mass spectra, infra-red and Rf values for fatty acid esters of larval faeces are given.
