Abstract
A field evaluation was made of 14 cultivars (11 Ghanaian and three exotic) of Solarium melongena to infestation by Leucinodes orbonalis. Infestation of both shoots and fruits of all cultivars increased steadily during the experimental period. Shoot infestation was significantly highest in the cultivar Nyadoahene and least in Pakro Special, Kwadaso 3C and Florida Market. Fruit infestation was also significantly highest in Nyadoahene. Fruits of the cultivars Black Beauty and Florida Market were significantly least infested. Florida Market showed the most resistance to the insect with respect to both shoot and fruit infestations. The cultivars Kwawu Ntrowa, Gaab, Danso II, Pakro 5, Odwanhwoa, and Pakro Special 5C (in that order) were the least resistant to shoot infestation, while Nyadoahene, Danso II, Gaab, Kwawu Ntrowa, Odwanhwoa, and Pakro 5 (in that order) showed the least resistance to fruit infestation. In general, the Ghanaian cultivars were more severely infested by L. orbonalis especially in the case of fruit infestation.
