【 摘 要 】

The objective of this work was to study the effect of diameter of the cotton squares in the corporal mass of adults of boll weevil, Anthonomus grandis Boheman (Coleoptera: Curculionidae). The assay was carried out under field and laboratory conditions, in Jaboticabal, São Paulo State, Brazil. Six samplings obtained from a random harvesting of ten plants of each cultivar (Coodetec 405 and Fibermax 986). The number and diameter of squares were recorded for each plant. Squares with oviposition orifices were kept individually in a recipient and observed daily until adult emergence. The larger the diameter of the squares, the more corporal mass of boll weevil newly emerged adults in both cultivars.
