Abstract:		"The ability to detect and remove dead adult bees is an essential part of honeybee colony fitness that prevents the spread of pathogens. Fatty acid olfactory cues stimulate undertaking behavior among different social species within Hymenoptera, but the chemicals responsible for the death cue in Apis cerana have not yet been identified. We explored the Nasonov gland as a potential source of these chemicals in A. cerana. Gas chromatography indicated that unlike A. mellifera, the A. cerana Nasonov gland does not contain any volatile terpenes, only fatty acids. As a bioassay, dead honeybees were rinsed free of their individual cuticular hydrocarbons via dichloromethane and two concentrations of oleic acid and a synthetic blend of the Nasonov pheromone in A. cerana were applied to the dummies. Results showed that oleic acid did not stimulate corpse removal in A. cerana. However, the synthetic pheromone blend of A. cerana Nasonov did stimulate removal"
