Abstract

A study was made of the reason for the fairly rapid loss of attractancy of pheromone traps for the European corn borer, Ostrinia nubilalis (Hübner). This loss in attractancy appeared to be attributable mainly to formation of an inhibitory or repellent substance(s). Although traps with a suspended pheromone dispenser were significantly more attractive than traps with the dispenser placed in contact with the adhesive, they still became relatively unattractive to male corn borers within approximately 1 week.
