Selection of Beauveria bassiana (Bals.) Vuill. isolates for controlling Sitophilus zeamais (Mots.) (Coleoptera: Curculionidae)

Sitophilus zeamais (Mots.) (Coleoptera: Curculionidae) is considered a major pest of maize, responsible for reducing grain quality and making the corn inappropriate for industrial use and human consumption. S. zeamais has been controlled exclusively with chemical products. The objective of this rese...
