| dc.description | The search for ecological alternatives for the control of C. sordidus, M. hemipterus is necessary and the use of entomopathogenic fungi must be considered within the management of these insect-pests; Within the species of entomopathogenic fungi we find Beauveria bassiana and Metarhizium anisopliae as potential natural regulators of insect populations harmful to agricultural crops. The research was carried out in the Entomology Laboratory of the Faculty of Agricultural Sciences. Laboratory materials were used. Two factors were studied: a) control of C. sordidus and M. hemipterus, b) dosage and biological controllers. The treatments, consisting of the fungal strains, with the respective doses, were evaluated. The randomized complementary blocks (RCD) experimental design was used with 6 treatments, 5 repetitions. Performing the Tukey test at 95% probability. The following variables were evaluated: number of live insects, number of dead insects, percentage of mycelium and mortality. Through the analysis of the results, it was determined that mortality of C. sordidus at 8 days was reported with the B. bassiana treatment 12 g/L (28.00) and the chemical treatment (Thiamethoxam) 12 ml/L (28.00 %) being numerically superior to the rest of the treatments. In the evaluation after 11 days, it was observed that the M. anisopliae 12 g/L (60.00%) treatment was statistically superior to the rest of the treatments. The percentage of mortality of M. hemipterus at 8 days was reported with the B. bassiana 12 g/L treatment (28.00%) and the M. anisopliae 8 g/L treatment (28.00%) being numerically higher than the rest of the treatments. In the evaluation after 11 days, it was observed that the B. bassiana 12 g/L treatment (56.00%) was statistically superior to the rest of the treatments. | es_ES |

| dc.description.abstract | La búsqueda de alternativas ecológicas para el control de C. sordidus, M. hemipterus son necesarias y la utilización de hongos entomopatógenos deben ser consideradas dentro del manejo de estos insectos-plaga; dentro de las especies de hongos entomopatógenos encontramos a Beauveria bassiana y Metarhizium anisopliae como potenciales reguladores naturales de poblaciones de insectos perjudiciales para los cultivos agrícolas. La investigación se realizó en el Laboratorio de Entomología de la Facultad de Ciencias Agropecuarias. Se utilizaron materiales de laboratorio. Se estudiaron dos factores: a) control de C. sordidus y M. hemipterus, b) dosis y controladores biológicos. Se evaluaron los tratamientos, constituidos por las cepas de hongos, con las respectivas dosis. Se utilizó el diseño experimental Bloques complemente al azar (DCA) con 6 tratamientos, 5 repeticiones. Mediante la prueba de Tukey al 95 % de probabilidades. Se evaluaron las siguientes variables: número de insectos vivos, numero de insectos muertos, porcentaje de micelio y mortalidad. Mediante el análisis de los resultados se determinó que mortalidad de C. sordidus a los 8 días se reportó con el tratamiento B. bassiana 12 g/L (28.00%) y el tratamiento químico (Thiamethoxam) 12 ml/L (28.00 %) siendo numéricamente superiores al resto de tratamientos. En la evaluación a los 11 días se observó que el tratamiento M. anisopliae 12 g/L (60.00 %) fue estadísticamente superior al resto de tratamientos. El porcentaje de mortalidad de M. hemipterus a los 8 días se reportó con el tratamiento B. bassiana 12 g/L (28.00 %) y el tratamiento M. anisopliae 8 g/L (28.00 %) siendo numéricamente superiores al resto de tratamientos. En la evaluación a los 11 días se observó que el tratamiento B. bassiana 12 g/L (56.00 %) fue estadísticamente superior al resto de tratamientos. | es_ES |
