The highest concentrations of phospholipid, neutral lipid and fatty acids were observed in the R cells and connective tissue of the hepatopancreas of Scylla serrata. The basal parts of the B cells and apical parts of the cells lining the main duct also showed moderate presence of these substances. The E cells however, except at their cell membranes were found to be devoid of lipids. F cells on the other hand exhibited lipoid complexes. Considerable reduction in the staining intensity of fatty acids were noticed 4 h after the bilateral ablation of eyestalks, neutral lipid undergo depletion 24 h after the operation whereas phospholipid reserves increase 48 h after the eyestalk removal. A fall in the quantity of neutral lipid and phospholipid was conspicuous when eyestalk extract was injected into normal or destalked crabs. From the present data it appears that R cells and connective tissue form major sites of lipid storage and in an intermolt animal eyestalk factor(s) may have an important role in the control of lipid metabolism.
