Occurrence of Diglycerol Tetradodecanoate Tetradecanedioate in Scale Insect, Phenacoccus pergandei COCKERELL (Hemiptera : Pseudococcidae)

Abstract

A new bimolecular-type dicarboxylic acid glyceride was isolated from the lipids of a scale iasect, Phenacoccus pergandei and its structure was shown to be diglycerol tetradodecanoate tetradecanedioate. This compound was the major lipid class present in the incect, constituting about 14% of the total lipids.
