Abstract
Fatty acid composition of glyceride and constituent of true wax in the lipids obtained from adult female insects have been analyzed by column, thin-layer and gas-liquid chromatographies. Eighty-three per cent triglyceride was the major component in the lipids from insect bodies. The fatty acid of the triglyceride had high contents of capric and lauric acid, 33.9, 38.5% respectively. Glycerides were not detected in the lipids obtained from the “Wax shell” which was excreted by insect. Twenty-two per cent true waxes and seventy-eight per cent other lipid classes composed the lipids. Cerotic acid and ceryl alcohol were the major constituents in the true wax'in addition to the small amounts of fatty acids (C14, C16, C18, C20, C22, C28) and fatty alcohols (C18, C20, C24, C28).
