Pheromone dispensers prepared by several companies were tested in Arkansas and in Texas. The lures contained about 25 mg grandlure (compared with 10 mg for the usual lure), and were prepared both with and without the enhancer, eugenol. Results showed that it is possible to prepare pheromone dispensers that will last one month or longer, and that eugenol greatly improves efficacy of the lures. In some programs the use of one month lures instead of the currently used ones lasting two weeks will yield considerable cost savings in labor.
