Effect of an infusion of canelo and bitter lupin on Aegorhinus superciliosus adults
A. superciliosus (Coleoptera: Curculionidae), known as "cabrito del maitén" (CM) among other names, is an important pest affecting fruit-bearing bushes in southern and central southern Chile. One means of control is the use of organically synthesized insecticides that target the adult, the...
