Abstract
The red coffee mite, Oligonychus ilicis, is a phytophage that damages coffee leaves by piercing their cells and consuming the cellular contents. This behavior impairs photosynthesis, and healthy growth of coffee plants. This study aimed to evaluate the acaricidal efficacy of the Baccharis dracunculifolia plant extract at various concentrations to control the red spider mite that affects coffee trees. The extract was applied directly to the leaves of Coffea sp. using the Potter's Tower methodology. Seven concentrations were tested, including the control, with seven repetitions each, containing ten mites per repetition. The extract of B. dracunculifolia showed acaricidal activity against adult mites of O. ilicis, and the analyses revealed consumption levels of phenolics, flavonoids, and tannins in the extract.
