The objective of this work was to evaluate the use of plastic bags to protect the fruits of Annona crassiflora (Annonaceae) against Cerconota sp. (Lepidoptera: Oecophoridae). As protection against this fruit-boring insect, 100 fruits were enclosed in plastic bags. Another 100 fruits were not bagged. The fruits were selected from the following five ranges of diameters: 1 = 0.5 – 1.99; 2 = 2.00 – 3.99; 3 = 4.00 – 7.90; 4 = 8.00 – 11.90; and 5 = 12.00 – 16.00 cm. The bagged fruits of various diameters were attacked less frequently by the pest. The bagged fruits with a diameter of less than two cm were not attacked. The percentage of fruits attacked and the number of larvae/fruit increased as the diameter of fruits increased in both treatments. The bagged fruits initially less than two cm in diameter showed the greatest final diameter and height.
