The black banana weevil is the most prevalent and destructive pest of Musaceae in all pantropical regions. At present, there is no other method more effective than pesticide applications for its total control, which has caused contamination of water sources and human health, so biological control techniques have been implemented, This research evaluated the performance of Heterorhabditis bacteriophora, Beauveria bassiana and Metarhizium anisopliae, a mixture of Beauveria bassiana and Metarhizium anisopliae for the management of this pest in the biopesticide laboratory and at the El Plantel farm of the National Agrarian University (UNA). In relation to the control of the pest, the bioformulation that presented the best results was the base mixture of Beauveria bassiana and Metarhizium anisopliae with 91. 25% effectiveness followed by the formulation of Beauveria bassiana with 87. 52% and Heterorhabditis bacteriophora with 2. 45% effectiveness in the field, no significant differences were found in the three laboratory controls, a significant difference was found between the fungi and the nematode in the field.
