Spodoptera litura (Lepidoptera: Noctuidae) is a polyphagous pest. It feed on more than 120 host plants. It causes economic losses of crops from 25.8%-100% based on crop stage and its infestation level in field. In the present study, Spodoptera litura feed on five tomato varieties (Pant Bahar, Ratna, Arka Saurabh, Pusa Gaurav, Arka Abha). Different growth parameters (fecundity, incubation period, hatchability) of pest were assessed on different tomato varieties in the laboratory. Results indicated that the maximum fecundity (695.33%) of pest was recorded on tomato variety Pant Bahar while minimum fecundity on tomato variety (672.33%) Arka Saurabh which was followed by Ratna (681.67%), Arka Abha (682.33%) and Pusa Gaurav (689.67%). Maximum incubation period was observed on tomato variety Arka Saurabh (8.65 days) and minimum on Pant Bahar (5.46 days) which was followed by Pusa Gaurav (6.33), Arka Abha (6.81) and Ratna (7.33). Maximum hatchability (94.33%) was found on tomato variety Pant Bahar while minimum (86.32%) on Arka Saurabh. It was clearly observed that Pant Bahar variety of tomato was proved to be most susceptible for the development of pest while Arka Saurabh was the most resistant variety against Spodoptera. litura.
