| dc.description | Banana (Musa sapientum) represents the fourth most important food index crop in the world, followed by rice, wheat and corn. It is important to consider that banana production can be affected by various factors, including agricultural pests. The black boll weevil (C. sordidus) is an insect pest considered one of the most damaging of all established musaceae, in which production losses of 42-45% of the total harvest have been reported. In established banana plantations, the insect pest produces tunnels inside the outer edge of the corm, causing rotting of the corm, yellowing of the leaves, energy loss, plant drop and sometimes sterility. The entomopathogenic fungus (B. bassiana) has been used effectively in the field and laboratory to control C. sordidus, reaching an efficacy of 97%, making it a valid alternative for the management of the black palm weevil. The information obtained was carried out through the technique of analysis, synthesis and summary, with the purpose that the reader knows about Beauveria bassiana for the control of (Cosmopolites sordidus) in the banana crop in the province of Los Ríos. Based on the above, it was determined that applications of (B. bassiana) on the black weevil achieved a 97.5% mortality rate 21 days after inoculation of the insects, with a concentration of 4x109 conidia/ml. The use of the entomopathogenic fungus (B. bassiana) can be considered as an efficient alternative for the control of the black boll weevil in banana plantations. | es_ES |

| dc.description.abstract | El banano (Musa sapientum) representa el cuarto cultivo de índice alimentario catalogado el más importante en el mundo, seguido del arroz, el trigo y el maíz. Es importante considerar que la producción bananera puede ser afectada por diversos factores, entre los que se destacan las plagas agrícolas. El picudo negro (C. sordidus), es un insecto plaga considerado uno de los más perjudiciales de todas las musáceas establecidas, en la cual se han reportado pérdidas de producción que representan entre el 42 - 45% de la cosecha total. En las plantaciones establecidas de banano, el insecto plaga produce túneles en el interior del borde exterior del cormo, provocando la putrefacción del mismo, el amarilleo de las hojas, el descuento de energía, la caída de la planta y a veces provoca esterilidad. El hongo entomopatógeno (B. bassiana), ha sido utilizado eficazmente a nivel de campo y laboratorio, para controlar C. sordidus, llegando alcanzar una eficacia del 97%, por lo que es una alternativa válida para el manejo del picudo negro. La información obtenida fue efectuada mediante la técnica de análisis, síntesis y resumen, con la finalidad de que el lector conozca sobre Beauveria bassiana para el control de (Cosmopolites sordidus) en el cultivo de banano en la provincia de Los Ríos. Por lo anteriormente detallado se determinó que Las aplicaciones de (B. bassiana), sobre picudo negro logran una mortalidad del 97,5% a los 21 días de la inoculación de los insectos, con una concentración de 4x109 conidios/ml. El uso del hongo entomopatógeno (B. bassiana) puede ser considerado como una alternativa eficiente para el control del picudo negro en las plantaciones de banano. | es_ES |
