Applying different infective structures of Beauveria bassiana to Coffea arabica infested with Hypothenemus hampei (Coleoptera: Curculionidae) under field

Coffee is the most appreciated beverage in worldwide; Brazil largest producer and exporter of this commodity. Organochlorine endosulfan was banned from country 2013 due to its teratogenic agent-related features. Since then, coffee plantations have experienced increased Hypothenemus hampei infestation rates. The aim current study assess variations rates Coffea arabica fruits brocaded by H. after application entomopathogenic fungal species Beauveria bassiana IBCB66. Experiments were carried out with ‘Catuaí’ ‘Mundo Novo’ cultivars between 2018 2020, during borer transit period. Three experiments based on aforementioned investigated plant species, both spraying sprinkling, at 30-day intervals; 10 collected per face each useful repetition. experiment has followed a randomized blocks design five treatments, including control, repetitions, each. Ecobass (IBCB66) wettable powder spray, concentration 2 × 1013·ha–1, used I II. On other hand, mix III prepared blastospores 5 1012·ha–1 + 0.1% Silwet. sprinkling process all three dry aerial conidia 1013·ha–1. Collected data subjected analysis variance (ANOVA), which Fisher’s test 5% probability level, SISVAR software. More than 35,000 assessed. In addition experiments, results evidenced that rate remained high.
