A monitoring experiment and a small scale mating disruption trial were carried out to investigate the potential value of the synthetic sex pheromone of the oriental tobacco budworm, Helicoverpa assulta (Guenee) (Lepidoptera : Noctuidae). The pheromone trap was more effective in detecting the field population than the black-light trap. The treatment with controlled-release PVC resin dispensers loaded with synthetic sex pheromone, applied at a rate of 30 g/ha in a hot pepper field, resulted in significant reduction of trap catches, indicating effective disruption of pheromonal cpmmunication of H. assulta in the field. The disruptive effect of the PVC formulation lasted for one month in the field.
