摘要

Sitophilus zeamaiz is one of the most damaging weevil species of stored grains in the world and a major cause of devastating losses. Its control is mainly based on synthetic products that are every day less effective. The current research work assessed the effects of castor oil, soybean oil; Neem and lily plant extracts on S. zeamaiz populations and their impact upon germination and physiological parameters of seedlings. Results have shown that soybean oil yielded the best control results, with mortality rates between 92 and 100% after 192 hours of the application. Nevertheless, soybean oil affects germination at 2000 - 10000 ppm rates. Neem extract reached mortality rates of 78.75 and 91.25% at 192 hours, with no impact on germination and agronomic properties. Finally, castor oil and lily extract did not yield high mortality rates over S. zeamaiz.
