Abstract
Adults and larvae of the Oriental Hornet (Vespa orientalis F.) have been fed on C14—labeled protein, derived from Chlorella, in order to determine to what extent such protein may be converted into carbohydrates. Only larvae were found capable of converting the labeled protein. Products of this conversion were the sugars glucose, fructose and sucrose, and also tri— and tetrasaccharides as yet unidentified. It is suggested that this ability of the larvae to carry out gluconeogenesis and the subsequent transfer of the formed sugars to the adults (in saliva droplets) may play an important part in the adult—larva interrelations of various insect societies.
