LEITE, Germano Leão Demolin et al. The bagging of Annona crassiflora fruits to control fruit borers. Acta Sci., Agron. [online]. 2012, vol.34, n.3, pp. 253-257. ISSN 1807-8621.  http://dx.doi.org/10.4025/actasciagron.v34i3.14713.

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.
