Field trapping with identified sex pheromones of the mahogany shoot borer, Hypsipyla robusta, was tested in a mahogany forest in Sabah, Malaysia. Traps with rubber septa impregnated with, synthetic (Z, E)-9,12-tetradecadiene-1-ol-acetate, (Z)-9-tetradecen-1-ol-acetate and a 5:3:2 mixture of (Z, E)-9,12-tetradecadiene-1-ol-acetate, (Z)-9-tetradecen-1-ol-acetate and (Z)-11-hexadecen-1-ol-acetate captured no males, although these compounds have been identified as sex pheromones of H. robusta.
