Colouring Matters of the Aphidoidea. XLIV. A Survey of Long-Chain Acid Derivatives From Aphid Lipids Compared With Those of Related Insects. Glycerides of Octa-2,4,6-Trienoic Acid

Abstract

A comprehensive survey of lipids representing all families of the Aphidoidea and several related families supports the chemotaxonomic separation of aphids and coccids from the remainder of the Hemiptera. Aphid glycerides are based chiefly on myristate, palmitate and sorbate as noted earlier; octa-2,4,6-trienoate residues are reported for the first time.
