Abstract: The weevil of corn kernels is the main pest of stored corn, affecting the quality of seeds and nutritional and market value. The objective of this work is to develop an economical and effective methodology for reproduction of this species for laboratory research purposes. 11 weevils infestations in health corn were oberved to know their reproductive capacity and count the number of weevils emerged in a period of 46 days after infestation. The maximum number of weevils emerged occurred in the infestations of December with 265,225, 186 and 171weevils corresponding to infestations of 14, 7, 21 and 28 on the same month, respectively. The accumulated adults emergenced were 686, 668, 597 and 443 weevils, respectively. The reproductive capacity of maize weevil, Sitophilus zeamais M., is favorable to obtain sufficient biological material for laboratory bioassays in economical and practical way.
