Abstract
The relative resistance of 76 pearl millet, Pennisetum americanum (L.) Leeke, cultivars to the rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae), was evaluated, and 37 of these were evaluated for resistance to the Angoumois grain moth, Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae), and the lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae). The reactions of the entries to the rice weevil and Angoumois grain moth were more similar than when either was compared with reactions to the lesser grain borer. No entry ranked most resistant or most susceptible to all insect species, but the inbred 4055 and ‘Senegal Bulk’ were somewhat resistant to all three species. Seed size varied inversely with resistance to the rice weevil and Angoumois grain moth, but it was less related to resistance to the lesser grain borer.Keywords
