Abstract
Groundnut oil applied to stored maize at 20 ml/kg gave complete mortality of the adults of Sitophilus zeamais Motsch. within 24 h. At 5 or 10 ml oil/kg, 100% mortality was obtained in 3 and 2 days, respectively, and with 1 ml/kg, 81% mortality was obtained after 13 days, as compared with 25% mortality after 13 days in untreated maize. Eggs were only present in the maize treated at 1 ml/kg, and their density and viability was significantly reduced as compared with no treatment. The oil treatment afforded some protection against reinfestation by adult weevils for 17 weeks; mortality ranged up to 37.5% among adults placed on maize treated 17 weeks previously at 0.2-0.4 ml oil/kg, and few progeny were produced
