Description
Summary:The insect pathogenic fungus Hirsutella eleutheratorum was first reported as a pathogen of coffee berry borer (CBB) Hypothenemus hampei in Colombia in 1993. A similar CBB pathogen identified as Hirsutella sp. was reported also from Colombia in 2007; attempts at isolation and in vitro culture of this fungus were unsuccessful. During 2016 and 2017 on the island of Hawai'i, extensive sampling of CBB populations was conducted in coffee fields treated with Beauveria bassiana-based biopesticides and in untreated fields. Among the samples collected from two high-elevation sites in the district of South Kona were rare findings of adult foundress CBB infected with a species of Hirsutella fitting the description of H. eleutheratorum. Prevalence of the pathogen was, in all cases, very low (
