Incidence of Listronotus bonariensis (Coleoptera: Curculionidae) in ryegrass pastures from southern Chile. New background

The Argentine stem weevil, Listronotus bonariensis, is an important pest in pastures, especially ryegrass (Lolium sp.), compromising grassland persistence and productivity. Both, adult and specially larvae cause severe damage, action that generate the death of the tiller and reducing forage producti...
