Biological control is used to reduce pest insect populations and is an alternative technique to the use of synthetic insecticides. The use of entomopathogenic fungi as microbial control, has advantages over chemical insecticides, among them its high specificity on the hosts and its low environmental pollution. However, the production of biological control agents such as Beauveria bassiana, presents limitations in the characterization and identification and selection of strains with high pathogenicity, likewise the potential that native strains can have for the management of insect pests in Mexico is unknown. The CP-MABb1 obtained a 99% homology for B. bassiana of the National Center of Biotechnology Information (NCBI), and presented the highest number of conidia and a viability of 53% in PDA culture medium, representing higher production of reproductive structures in comparison to the commercial strain, virulence determinants and selection in the biological control of pests.
