Five trap designs yellow and white funnel, Delta red and white and universal were evaluated for their catching efficiency. Yellow funnel was most efficient for catching male moths followed by white funnel and then Deltas red and white. Universal trap was most inefficient. In the field where no plant protection was given against bollworms and mass trapping was done, pink bollworm infestation in the bolls was much less as compared with untreated check (control). In area where insecticides were compared with mass trapping, reduction in pesticide use was 33 percent. Infestation in the bolls was much less than where farmer used insecticides. Pink bollworm control with PB Rope, small and large Tea Bags by using mating disruption technique was better than that of plots where farmer used insecticides. Maximum pink bollworm attack was 22 percent in the insecticide treated area as compared with 6% in the pheromone treated block.
