Abstract

Entomopathogenic fungi have potential as biocontrol agents against insect pests, and mycovirus-mediated hypervirulence may enhance their efficacy. Before initiating research on hypervirulence, the presence or absence of double-stranded (ds) RNA elements was determined in 94 Korean entomopathogenic fungi. dsRNA elements varying in size from ca. 0.8 to 7 kbp were found in 14.9% (14/94) of the strains examined, including Beauveria bassiana, Metarhizium pemphigi, M. pinghaense, M. rileyi, and Cordyceps fumosorosea. This study provides information on the incidence and electrophoretic banding patterns of dsRNA elements and is the first report of mycoviruses entomopathogenic fungi in Korea.
