Efficacy of Botanicals Against Maize Weevil <i>Sitophilus zeamais</i> (Motschulsky)

Maize weevil Sitophilus zeamais (Motschulsky) is the most dangerous storage insect pest that causes high maize grain loss in storage. The present experiment was conducted in laboratory to evaluate botanical management practices. The results showed that all botanical oils (Helianthus annuus, Sesamum indicum, Brassica napus, Guizotia abyssinica) and Talik 2% provided high mortality, low progeny emergence, high inhibition, low hole number/ grain, low weight loss and high germination.
