The tobacco caterpillar, Spodoptera Utura F. is one of the most damaging insect pests on several field and vegetable crops. Sex pheromone, ‘litlure’ was used as an attractant in pheromone traps to monitor male moth activity, and to study the relationship between male moth catches in traps and oviposition in field crops at the Crop Research Centre, Pantnagar, India. Pheromone traps effectively monitored population fluctuations and showed seven peaks during 1988 and 1989. Two peaks were observed during the spring/summer season, three in the rainy season and the remaining two peaks in the postrainy season. Few moths were caught during the winter. Significant correlations were found between number of male moths in traps and number of egg masses laid on sugarbeet during spring, on groundnut and soybean during the rainy season, and on cauliflower during the postrainy season. However, there was no oviposition in Kharif sown urdbean and in summer groundnuts. Pheromone traps, therefore, can be used as a monitoring tool to ensure the rational application of insecticides
