Abstract Rhyzopertha dominica (F.)(Coleoptera: Bostrychidae) is one of the main stored
grain pests in the world. The present study describes the investigation of the insecticidal
activity of essential oils (EOs) extracted from the leaves of twelve Myrtaceae species against
this important pest. The essential oils of Eucalyptus resinifera Sm.(Myrtaceae) were the most
actives and presented 1, 8-cineole (59.3%), p-cymene (12.9%), and α-pinene (9.7%) as the
main components. Contact bioassays revealed that the EOs of E. resinifera were less toxic …
