Abstract:

Eight locally improved pearl millet (Pennisetum americanum (L.) Leeke) cultivars were compared with the traditional cultivar 'Souna' during the 1982-1984 crop seasons for their reaction to the attack of three insect pests and two diseases in Senegal. In 1984, 'H9-127' harbored lower larval populations of Lema plantfrons Weise (Coleoptera: Chrysomelidae) than seven cultivars tested. When the level of stalk infestation and number of larval Acigona ignefusalis Hampson (Lepidoptera: Pyralidae) were compared among the nine cultivars, none was resistant. Cultivar '!BV-800!' showed the least susceptibility to Raghuva albipunctella De Joannis (Lepidoptera: Noctuidae), downy mildew (caused by Sclerospora graminicola (Sacc.) Schroet.), and head smut (caused by Tolyposporium penicillariae Bref.). Because 'IBV-8001' is more resistant to one insect pest and two diseases and its yields are higher than those of 'Souna', its general cultivation is recommended in major millet-growing zones of Senegal.
