Synergism of the Sex Pheromone of the Cranberry Girdler123

Abstract
In field tests, traps baited with 1000 μg of (Z)-11-hexadecenal (the known pheromone component) and 25–50 μg of (Z)-9-hexadecenal captured 6 times as many male Chrysoteuchia topiaria as did traps baited only with 1000 μg of (Z)-11-hexadecenal.
