The increasing trend of insecticide resulted in insecticide resistance; resultantly alternate options are requisite to manage insect pests. Pheromone traps are used to capture the flying insects of the opposite sex. They are used to monitor the presence of lepidopterans moths in a specific locality. Present studies were carried out to assess the population abundance of lepidopterans moths of cotton. For this purpose, specific lures of each lepidopterans moth were installed all around the cotton field at the height of 5 feet. Based on the results of the present studies, it was found that pink bollworm was more abundant amongst all the other moths of cotton. It was the most damaging insect pest of cotton. Its peak trapping was recorded during the months of September when day and night temperature reaches to 35 and 25 ˚C respectively. From the results, it was found that pheromone traps are a very useful source of monitoring lepidopterans moths.  It was concluded that the efficiency of pheromone traps was high at limits of 30-35 ˚C day and 20-25 ˚C night temperature.
