Food consumption and growth rates of banana weevil (Cosmopolites sordidus (Germar)) feeding on a resistant and a susceptible banana cultivar were compared. First instar larvae (<24hr old) were offered weighed pieces of food material that were changed every 4-7 days. At each food change weights of food material and larvae were recorded. Changes in weight of food material and larvae were calculated to determine food consumption and larval growth rates. Larvae feeding on the resistant cultivar had lower food consumption and growth rates, longer developmental duration and lower pupal weight compared with larva feeding on the susceptible cultivar.
