Certain agroecological practices, such as implementing crops in agroforest systems favor biodiversity and, consequently the presence of certain biological control agents. Among these agents, predatory ants might play an important role for crop production. This study was intended to determine whether the presence of ants might affect coffee production weight two shade–management systems. Partially controlled trials were carried out, the exclusion of ants in 4 coffee plots: two with tree shade and two without shade (sun). In each plot, 45 coffee bushes were randomly selected and two treatments were established in two branches, with and without exclusion of non-flying anthropods. Ants and coffee grains were collected every two weeks, as they ripen. The coffee grains were manually processed (peeled, dried and thrashed) in order to obtain the final product, which was weighed. Although no statistical differences were found between treatments, coffee weight tended to be higher in
