Studies on lipids in some Homopterous insects

Abstract: There is little information available on the occurrence of lipids in aphids or other sucking insects, and little is known of the role of lipids in aphid nutrition. The purpose of the present investigation was to obtain preliminary information on several phases of these problems. The classes of lipids extracted from one aphid, Macrosiphum barri Essig, were separated by column chromatography. The fatty acids in each of these classes as well as in the crude lipid extracts from 20 other species of aphids and six species of leafhoppers were separated by gas-liquid chromatography. Nearly all of the fatty acids in M. barri were in the form of triglycerides, as in other insects that have been studied by previous investigators. The free fatty acids accounted for only a small percentage of the total quantity of lipids extracted from M. barri.
