This work research was aimed at studing some characteristics of the adult phase of two species of citrus root weevils. Naupactus cervinus Boheman, Naupactus versatilis Hustache were collected from citrus in Itapetininga, SP, and taken to the Insect Biology Laboratory of ESALQ/USP, in Piracicaba, SP. Longevity, feeding time, pre-oviposition period, oviposition, number of egg-laying and eggs, and the consumption of the citrus leaf during the adult phase were evaluated. N. versatilis is potentially more dangerous to citrus, because it lays a larger number of eggs (214.6 x 120.9 eggs), has a higher longevity (30.9 x 25.2 days) and consumes a larger leaf area (31.0 x 15.0cm²).
