This study shows a comparative assessment of a new way synthesized pheromone Heliothis armigera activity compared to pheromone activity synthesized by standard scheme. In addition, for this sex pheromone, new dispensers were tested in the field conditions. New dispensers, such as fragments of synthetic twine 2.5cm/2.5mg of pheromone non-PVC coated showed similar to the standard attractiveness of male cotton bollworms. However, the cost of new dispensers is 30% less.
