In mass production, the carbon nitrogen (C: N) ratio affects the growth and production of conidia. The objective was to evaluate B. bassiana and M. anisopliaenativos in solid substrates rice (Oryza sativa L.) and corn (Zea mays L.) enriched with nutritional supplements, molasses (source-carbon) in concentration (2.5-5.0 g ), amaranth and soybean meals, milk powder and yeast (nitrogen sources) of concentration (0.25-0.50 g), compared with controls. The C: N ratio was 10: 1. The experimental design was Categorical Multi-Factorial and the technique, observation. The mass production of fungi was solid fermentation in 40 treatments with 3 repetitions; the count of conidia in the Neubauer chamber; and, the analysis of results with Statgraphics Plus-Ver.5.1, IBM-SPPS-Ver.22 and Excel-2013. The best production of B. bassiana in rice was T13 (molasses-2.5 and milk-0.25) g with an average of 1.89 ...

Determina si el aislamiento de las cepas nativas desde diferentes fuentes y la adición de suplementos nutritivos a los sustratos sólidos arroz (Oryza sativa. L.) y maíz (Zea mays. L) generan un incremento significativo en la producción y virulencia de Beauveria bassiana y Metarhizium anisopliae sobre Hypothenemus hampei y Mahanarva andigena en el laboratorio, como un aporte a los estudiantes de Ingeniería Agroindustrial y Agronomía de la Universidad Estatal de Bolívar. Para ello, las cepas nativas aisladas de los hongos entomopatógenos en cuestión se someten a diferentes tratamientos, resultando el mejor sustrato nutritivo (sustrato más el suplemento nutritivo melaza y leche en polvo, concentración 2,5 g - 0.25 g), en arroz y maíz para B. bassiana y M. anisopliae el T13, T14, T33 y T34 con 1,89×109 y 1,86×109 conidios/g; 2,50×109 y 2,05×109 conidios/g, respectivamente.
