Along with the major component, (E1–10–hexadecenal (E10–16: Al,), two minor components, (Z)‐10‐hexadecenal(Z10‐l6:Aid) and hexadecanal (16: Ald) were identified as components of the sex pheromone of Dichocrocis punctiferalis Guenee. Analysis of single sex pheromone gland extracts by capillary gas chromatography indicated that the relative ratio of 16:Ald, E10–16:Ald t and 210–16:Ald was equal to 13. 0:80. 4:6. 6 respectively. Field trails indicated that 210–16: Ald and 16: Aid alone caught no males. The most attractive was a blend containing 16: Ald, E10–16:Ald, and 210–16: Ald at a ratio of 16:100:8, and a two‐compound blend of E10–16:Ald and 210–16:Ald at a ratio of 100:8.
