Producción y uso del hongo Metarhizium anisopliae Mestsh Sor 1879 en el control del picudo negro del banano Cosmopolites sordidus Germar 1824

The production process of the M. anisopliae fungus involves a series of stages that aim to obtain a product that has the greatest number of viable spores for the control of C. sordidus in banana cultivation under field conditions. This bibliographic research work was developed as a non-experimental component, through a technique of analysis, synthesis and summary of the information obtained. From the above details, it is determined that the black weevil C. sordidus is considered a pest that causes significant damage to banana crops, where it makes galleries in the corm, weakening the plant, causing overturning and causing the loss of productive units. The fungus M. anisopliae has a broad control effect against the insect pest C. sordidus; The life cycle of this entomopathogenic fungus consists of a phase of infected cells in the insect body and a second saprophytic phase when the fungus uses nutrients from the insect body to complete the cycle. Efficient results have been presented between 85% and 95% mortality on C. sordidus when using the fungus M. anisopliae with a concentration of 5 x 108 allowing the insect to walk on the strains of the fungus or on the pseudostem pieces treated directly, so that insects infect them during the colonization process. The production, activation, conservation and formulation of M. anisopliae is feasible at the laboratory level, in which its virulence and its controlling capacity in the field must be ensured
