| dc.description | Beauveria bassiana (Balsamo) Vuillemin has been registered as a biological enemy of the coffee berry borer, being isolated in all countries where this insect has migrated. Infection of H. hampei is predictable from the precise susceptibility of this insect to CBB attack. As with the maximum entomopathogens formulated for the control of pest insects within the discipline, positive components that define success in their implementation in control applications must be taken into account. The CBB attacks and reproduces in fruits that reach 20% or more of their dry weight, which takes place, depending on the temperature, between 90 and 120 days after flowering. This is the most opportune time to spray with B. bassiana and get the fungal spores in contact with the CBB adults that are penetrating the fruit. If the CBB has already entered the fruit, contact is difficult and the impact of the fungus is almost nil. The information obtained was carried out through the technique of analysis, synthesis and summary, with the purpose of informing the reader about the production and use of the fungus Beauveria bassiana in the control of coffee berry borer Hypothenemus hampei. From the above detailed it was determined that the production of B. bassiana in bottle (3.87 x 1011 conidia), is sufficient to spray 400 coffee trees of 4 years of age and the use of a spray device with previous pressure retained at 40lbs/in", with a HC-3 nozzle of low discharge (190 cc/min) and with an extension of application of 50 cc of aggregate according to the tree. The high concentration of B. bassiana and its true quality (viability and pathogenicity) create a strong inoculum pressure on the CBB population. The efficacy of B. bassiana in CBB control associated with the location of the branch on the tree where the insect attacks the fruit is variable. Higher mortality has been found on lower branches, probably due to higher humidity and lower solar radiation. Through several evaluations of four doses between 1x108 and 5x109 spores/tree of Bb9205, it was confirmed that the higher the dose, the higher the mortality on CBB. | es_ES |

| dc.description.abstract | Beauveria bassiana (Balsamo) Vuillemin ha sido registrado como enemigo biológico de la broca del café, siendo aislado en todos los países a los que ha migrado este insecto. La infección de H. hampei es predecible a partir de la precisa susceptibilidad de este insecto al ataque de la broca. Al igual que con los máximos entomopatógenos formulados para el control de insectos plaga dentro de la disciplina, se deben tener en cuenta componentes positivos que definen el éxito en su implementación en aplicaciones de control. La broca ataca y se reproduce en los frutos que alcanzan el 20% o más de su peso seco, lo que tiene lugar, según la temperatura, entre 90 y ciento veinte días después de la floración. Este es el momento más oportuno para pulverizar con B. bassiana y conseguir que las esporas del hongo entren en contacto con los adultos de la broca que están penetrando en el fruto. Si la broca ya ha entrado en el fruto, el contacto es difícil y el impacto del hongo es casi nulo. La información obtenida fue efectuada mediante la técnica de análisis, síntesis y resumen, con la finalidad de que el lector conozca sobre la producción y uso del hongo Beauveria bassiana en el control de broca del café Hypothenemus hampei. Por lo anteriormente detallado se determinó que la producción de B. bassiana en botella (3,87 x 1011 conidios), es suficiente para rociar 400 cafetos de 4 años de edad y el uso de un dispositivo de pulverización con presión previa retenida a 40lbs/in", con una boquilla HC-3 de baja descarga (190 cc/min) y con una extensión de aplicación de 50 cc de agregado según el árbol. La alta concentración de B. bassiana y su verdadera calidad (viabilidad y patogenicidad) crean una fuerte presión de inóculo sobre la población de la broca. La eficacia de B. bassiana en el control de la broca asociada a la ubicación de la rama en el árbol en la que el insecto ataca el fruto es variable. Se ha encontrado una mayor mortalidad en las ramas más bajas, probablemente debido a una mayor humedad y una menor radiación solar. Mediante varias evaluaciones de cuatro dosis entre 1x108 y 5x109 esporas/árbol de Bb9205 se confirmó que, a mayor dosis, mayor mortalidad sobre la broca del café. | es_ES |
