| dc.description | SUMMARY The present work of a bibliographical investigative nature, focused on the problems of the pest insect known as ¨black weevil¨ (Cosmopolites sordidus), which is of great economic importance in the agronomic management of the banana crop at the level of our country, the information compiled reveals the incidence and severity of damage caused by said pest, due to its characteristics and eating habits, weevils are hard-bodied cockroaches (belonging to the coleoptera order) that are characterized by presenting a strong beak that serves to feed and to make small holes in the speudotalls and corm of the plants that attack, the larvae or worms that cause damage by consuming the tissue, cause wounds that weaken the plant and are the gateway to pathogenic microorganisms such as the causative agents of the disease. Panama and moko, etc. Among the control methods of this insect, the literature reports several, such as: chemical, biological, cultural control, including combinations of these, making use of traps to reduce populations and thus minimize damage by reducing the threshold of economic damage of the weevil. and increase the yield of the plantain crop. | es_ES |

| dc.description.abstract | RESUMEN El presente trabajo de carácter investigativo bibliográfico, se enfocó en función de las problemáticas del insecto plaga conocido como ¨picudo negro¨ (Cosmopolites sordidus) mismo que es de gran importancia económica en el manejo agronómico del cultivo plátano a nivel de nuestro país, la información recopilada nos da a conocer la incidencia y severidad de daños que ocasiona dicha plaga, debido a sus característica y hábitos alimenticios, los picudos son cucarachones de cuerpo duro (pertenecientes al orden coleóptera) que se caracterizan por presentar un pico fuerte que le sirve para alimentarse y para hacer pequeñas perforaciones en los speudotallos y cormo de las plantas que atacan, las larvas o gusanos que causan daño al consumir el tejido, provocan heridas que debilitan a la planta y son puerta de entra a microorganismos patógenos como los agentes causales del mal de Panamá y del moko, etc. Entre los métodos de control de este insecto la literatura reporta varios, tales como: control químico, biológicos, culturales, inclusive combinaciones de estos, haciendo uso de trampas para reducir las poblaciones y así minimizar los daños disminuyendo el umbral de daño económico del picudo negro y aumentar el rendimiento del cultivo de plátano. | es_ES |
