Farmers who grow ilama (Annona diversifolia (L.) Saff.) in small orchards and backyards have had pest problems during the past 5 years. During a tour in towns at seven municipalities, a weevil (Optatus palmaris Pascoe) was observed as the principal cause of damage to the fruits of ilama in the northern region of the State of Guerrero. Damage by the weevil ranged from 5 to 100% (total fruit damage). Fruits damaged and oviposited in by O. palmaris do not reach physiological maturity and fall to the ground. Adults of O. palmaris when feeding on the exocarp of ilama cause necrosis and loss of quality of fruit for commercialization and economic loss of income for the farmer.
