the honey bee , apis mellifera , does not convert c28 and c29 phytosterols to cholesterol as found in most previous studies of phytophagous or omnivorous insects , but instead the workers and queens selectively transfer 24-methylenecholesterol , sitosterol and isofucosterol from their endogenous sterol pools to the brood larvae regardless of the sterol in the worker diet .
