Due to its behavior, coffee berry borer (CBB) is difficult to control because its life cycle takes place inside the coffee fruits. A control alternative is biological control through the increase of predators capable of penetrating through the holes of the infested fruits in the field. For this, the predators Cathartus quadricollis and Ahasverus advena were evaluated in the field. The experimental units consisted of a productive coffee tree, enclosed with an entomological cage. In each tree, 50 coffee beans infested for 20 days with CBB were located, hanging from a branch (to evaluate it with both species) or placed on the ground (for A. advena). There were two treatments and two controls, with15 repetitions per treatment. From each predator species 150 adults were released, evaluating the CBB population and the infested fruits on the tree after 50 days. The 5% analysis of variance showed statistical differences between treatments in the number of live CBB stages and infested fruits, using the two predator species. Dunett's test at 5% indicated that A. advena reduced CBB by up to 70.1% when it was placed in the aerial part of the tree and by 76.4% when it was placed on the ground. Similarly, C. quadricollis adults significantly decreased infested fruits on the tree by 50.1% when the grains were placed on the branches. These predators are potential species to be included in an integrated pest management strategy for CBB.
