In this study, the population growth of Callosobruchus maculatus reared on beans from four cowpea cultivars fertilized with different nitrogen sources was evaluated. The factors tested were beans from four cowpea cultivars and seven different nitrogen sources: mineral N fertilization, inoculation with five strains of symbiotic diazotrophic bacteria, and soil nitrogen (absolute control).openAccessAdubação nitrogenadaGrãos armazenadosFeijão caupiRizóbioInoculationNitrogen fertilizationCowpeaAdubaçãoGenótipoCallosobruchus MaculatusInoculaçãoRhizobiumArtigo de periódico
