摘要:

Eleven okra lines collected from Imo, Anambra and Rivers States were evaluated in the glasshouse for resistance to S.derogata.The materials included four improved lines while the other seven were locally collected. The plants were grown for eight weeks in the glasshouse before they were infested for 2 days with 12 pairs ofS. derogatareared in the laboratory on 20% honey concentration. Damage by S.derogatawas recorded 14 days from introduction of the moths. The mean number of leaf rolls per plant showed that NHAE 47–4 and L‐O‐2 were highly susceptible while OP80, L‐O‐4 were the least susceptible.
