Response of American bollworm, Heliothis armigera (Hubner) to pheromone trap was investigated on 4 rai tomato field, Kasetsart University, Kamphaeng Saen, Nakhon Pathom. The effects of pheromone trapping to the number of eggs of H. armigera were shown. Egg number at its peak, average 386 eggs per 100 plants was found during third to fourth week after tomato's transplanting. As for the result from pheromone trapping itself, it was found that during the week without pheromone trapping, the number of egg was more than those found during the week with pheromone traps. Nevertheless data on this show no significant difference. The level of abundance of H. armigera moth was monitored by pheromone trapping, the highest number was averaged at 4.5 moths per trap at sixth to seventh week after tomato's transplanting.
