Ventral eversible glands (VEG) were removed from larvae of the fall armyworm, Spodoptera frugiperda (J. E. Smith), and extracted with methylene chloride. GC analysis of the VEG extract showed that the volatile components were about 98% saturated hydrocarbons. The distribution of individual hydrocarbons was as follows: n-tridecane, 0.1%; n-tetradecane, 2.4%; n-pentadecane, 96.2%; n-hexadecane, 0.3%; and n-heptadecane, 1.0%. Other components present at low levels were 1-pentadecene and three sesquiterpenes. A logarithmic increase in n-pentadecane level in the VEG occurred with successive molts from the third through fifth instar. The level of n-pentadecane in the VEG was empirically higher in fifth instar larvae feeding on corn foliage than in larvae feeding on a pinto bean diet or on cotton or peanut foliage.
