Spodoptera litura is a global and major pest, which attacks a good range of cultivated plants including wheat, pulses, oilseeds, fiber crops, vegetables and decorative plants. This pest can grow and survive on several plant species, belonging to approximately 37 families in India and it feeds on at least 157 plants species. There is a need for a more imaginative and holistic approach to research directed towards the management of this pest. In the present study we analyzed the impact of different tomato varieties on adult emergence, sex ratio and longevity of Spodoptera litura. In the present experiment we used Arka Abha, Arka Saurabh, Pant Bahar, Ratna and Pusa Gaurav tomato varieties as artificial diet for the pest. Results indicated that adult emergence of Spodoptera litura was minimum (69.33%) on variety Arka Saurabh and maximum (85.64%) on variety Pant Bahar. It is recorded from the data that the male longevity is maximum in Pant Bahar (30.33 days) and minimum in Arka Saurabh (23.92 days). It is amply documented that maximum female longevity recorded in Pant Bahar (38.65%) and minimum female longevity recorded in Arka Saurabh (31.65%). It is apparent from the data that the minimum sex ratio observed in Arka Saurabh (1:1.23) and maximum sex ratio recorded in Pant Bahar (1:1.93).
