Sex pheromone of the cotton caterpillar, Diaphania indica (Saunders) (Lepidoptera : Pyralidae): Identification and field attraction
Applied Entomology and Zoology 33 (3), 429-434
Abstract: Extracts from the abdominal tips of female moths of the cotton caterpillar moth, Diaphania indica (ca. 15.4 ng/female and 7.6 ng/female, respectively) yielded major EAG-active components that were identified as (E)-11-hexadecenal (E11-16:Ald) and (EE)-10,12-hexadecadienal (E10E12-16:Ald). Hexadecanal (16:Ald) was also found and determined to be at a ca. 2% level compared with E11-16:Ald. Mixture of synthetic E10E12-16:Ald and E11-16:Ald showed attractiveness to males in the field, although it was inferior to three 2-d-old virgin females. The addition of 16:Ald at 0.5% to 10% amounts of E11-16:Ald did not effect the trap catches.
