Associa es entre Cinara atlantica, seus inimigos naturais e formigas

The study of the relationship between species or populations is an excellent tool to learn about ecological phenomena. Among the possible interaction between two species, it is highlighted the mutualism between ants and insects that produce honeydew. While honeydew is "garbage" for the aphids it can be a food source for ants. The type of interaction between aphids and their natural enemies, known as "intraguild predation" or predation of natural enemies that share the same prey is an interaction that occurs in aphid communities. The majority of natural enemies in this system interact asymmetrically according to differences in body size, feeding strategy and priorities of each species. In agroecosystems, the consequence of this relation becomes particularly important for the biological control of pests of economic importance. In Brazil, few publications refer to the association among ants, aphids and their natural enemies, specifically in forest areas. Thus, this work had the objective to review studies regarding these association and discuss a field observed case involving the giant conifer aphid, Cinara atlantica (Hemiptera: Aphididae), its natural enemies and the ants Solenopsis invicta and Camponotus rufipes, occurring on Pinus taeda.
