Wax esters of secondary alcohols constitute 18–20% of the cuticular lipid extract of Melanoplus packardii and 26–31% of the cuticular lipids of Melanoplus sanguinipes . The total number of carbons in the wax esters range from 37–54 with 41 predominating in both species. The fatty acids of M. packardii wax esters are 16∶0, 18∶0, 14∶0, 20∶0 and 12∶0 in decreasing quantity. The fatty acids of M. sanguinipes wax esters are 18∶0, 20∶0, 16∶0 22∶0, 14∶0, 19∶0 and 17∶0 in decreasing quantity. The secondary alcohols from the wax esters of M. packardii are C 25 , C 23 and C 27 in decreasing quantity, and the secondary alcohols of the M. sanguinipes are C 23 , C 25 , C 21 , C 27 , C 24 , C 22 and C 26 in decreasing quantity. Each secondary alcohol consists of two to four isomers with the hydroxyl group located near the center of the chain.
