Bioactivity of Peumus boldus Molina, Laurelia sempervirens (Ruiz & Pav.) Tul. and Laureliopsis philippiana (Looser) Schodde (Monimiacea) essential oils against Sitophilus zeamais Motschulsky

The maize weevil (Sitophilus zeamais Motschulsky) is one of most important pest of stored seeds worldwide, but its current control method is based on the use of synthetic insecticides, usually leading to undesirable problems such as insecticide residues on treated food, human intoxications, and inse...
