Abstract

Identification of an attractant for the caneborer Sesamia grisescens Walker (Lepidoptera: Noctuidae).

Abstract

The composition of the sex pheromone of Sesamia grisescens was studied using GC, electroantennograms and field trapping on sugarcane in Papua New Guinea. (Z)-11-Hexadecenyl acetate and (Z)-11-hexadecenol were identified in field tests as the major attractants. Trapping trials identified a 3:2 blend of these compounds as the most effective bait. GC indicated the presence of hexadecyl acetate, (Z)-9-hexadecenyl acetate, (Z)-9-hexadecenol and (E)-11-hexadecenyl acetate in the pheromone gland, but these compounds had no significant effect on trap catches when added to the major components. Traps baited with the major components in a 1:1 ratio caught more adult males than traps baited with virgin females.
