Abstract

The aim of this study was to assess the transmission of the entomopathogenic fungus Beauveria bassiana among adults of banana weevil (Cosmopolites sordidus) in the field. C. sordidus healthy adults were marked and released on the basis of banana plants. Two days later insects marked and inoculated with the entomopathogenic fungus were released in the same area. Pseudostem traps were placed at 7, 14, 21 and 28 days for recover of released insects and to evaluate the mortality. It was observed that 3.7% of the non inoculated insects died due to pathogen infection caracterizing B. bassiana transmission between inoculated and healthy insects due to an increase in natural pre-existing prevalescence that was 0.3% of infected insects.
