Abstract

                                Laboratory and field experiments on the ovipositional preference of Helicoverpa urmigera (Hubner) on tomato revealed that more eggs were laid on the under surface of leaves than on the petiole, inter nodal stem and calyx. Hairy varieties received more eggs than the glabrous varieties. The cultivar Paiyur-1 combining the character of less trichromes and longer calyx received less eggs than the cultivars Madanapalli and PKM-1,
