Nutritional indices of Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) in response to feeding on three different host plants were evaluated under laboratory conditions. Food consumption, assimilation and tissue growth were maximum for the larvae fed on Lycopersicum esculentum (tomato) than those of Pisum sativum (pea) and Zea mays (maize). Mean values of approximate digestibility (AD), efficiency of conversion of digested food into body tissue (ECD) and efficiency of conversion of ingested food into body tissue (ECI) fall in the range of reported values for lepidopterans.
