Male hairpencil scent of Conogethes punctiferalis was analyzed and its function was studied. A component detected by GC-EAD, was identified as (E)-2-methyl-2-butenoic acid (tiglic acid) by GC, GC-MS. Males had no tiglic acid right after emergence but tiglic acid concentrations increased to an average of 1-2 μg/male by 2 weeks. Males with hairpencils from which tiglic acid was washed away by hexane and with removed hairpencils showed significantly lower mating success than control males. Less mating success occurred in females antennectomized bilaterally and normal males than with normal pairs. Tiglic acid was concluded to be a sex pheromone which functions in conspecific male recognition and also may be important as an aphrodisiac pheromone. Small numbers of males were attracted to hairpencil extracts or tiglic acid in a wind tunnel, but females showed no orientation or attraction to tiglic acid.
