The morphometrics of the Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) reared on tomato, potato and brinjal were analysed at the Insectary, Department of Entomology, S V Agricultural College, Tirupati. The results showed that the mean length and width of egg, I, II, III and IV instar larvae, pupa and adult was maximum when reared on tomato. The mean width head capsule of all instars was also more. These findings clearly indicated the preference of T. absoluta for tomato compared to potato and brinjal.
