The total body lipid and fatty acid composition of last instar larvae of the Indian-meal moth, Plodia interpunctella, and almond moth, Cadra cautella, reared on a turkey mash diet was determined. Male P. interpunctella larvae contained significantly higher (lA-fold) total body lipid than females, while no differences between the sexes of C. cautella larvae were observed. The relative abundance of the fatty acids palmitate, palmitoleate, stearate, oleate, lineoleate, and linolenate was similar in both sexes of P. interpunctella and C. cautella. The accumulation of individual fatty acids in larvae of both the moth species did not correspond to levels of fatty acids in the diet. The accumulation of palmitate, palmitoleate, and oleate in moth larvae of both the species was greater than linoleate and linolenate, suggesting a sparing effect by the former on the latter, more unsaturated fatty acids.
