The California Prionus (Prionus californicus Mots), has been a pest of Idaho hop fields for over 70 years. It has been thought for many years that female P. californicus use a sex pheromone to attract males for mating. We conducted experiments using an olfactometer to determine if male beetles respond to olfactory cues from female beetles. In addition, headspace volatiles collected from P. californicus adults were analyzed by GCMS to determine if differences exist in volatile profiles from male and female beetles.
