Body fat of the two scale insects, C. rubens and C. japonicus, was studied. After extraction, the triglycerides were isolated by preparative thinlayer chromatography. Composition of the triglycerides was determined by a pancreatic lipase hydrolysis and a gasliquid chromatographic analysis. A similar distribution pattern of triglycerides was found in these two insects. The completely saturated type (S3) consisted of the most part of total triglycerides; 75.5 mole % in the rubens fat and 83.5 mole % in the japonicus fat. It was noted that capric and lauric acids were the two major components in these triglycerides. In the unsaturated triglycerides, only S2U type was significant in amount. The data may suggest that the body fats of Ceroplastes genus consisted mainly of medium-chain triglycerides containing a large amounts of capric and lauric acids.
