ABSTRACT
Lipid extraction of larvae was carried out following FOLCH et al. (1957). The lipids were separated with T.L.C., followed by G.C. (transmethylation of the fatty acids and silylation of the sterols).
The absence of C16:1 in the classes of free fatty acids and diglycerides for dronelarvae and the presence of C18:2 in the classes of triglycerides and phospholipids for dronelarvae suggests different metabolic pathways of lipids in drone– and worker larvae.
The increasing amount of stigmasterol in dronelarvae (L5) seems to be very important.
