Leaves, stems and seeds powder of neem (Azadirachta indica A. Juss.) used as repellent of Sitophilus zeamais (Coleoptera: Curculionidae) in stored corn
Sitophilus zeamais is considered one of the most important pests of stored grain. In order to search alternative methods for controlling this pest the action of neem was evaluated in laboratory (Azadirachta indica A. juss.) in the behavioral and food processes of adults of S. zeamais.
