Abstract
Bands of double-stranded RNA (dsRNA) were detected in three out of twelve i solates of Paecilomyces fumosoroseus. Identity of these bands was confirmed by RNAse, DNAse and S1 nuclease treatments. The cure of dsRNA for one isol ate (P92) was successfully carried out for a single conidium subculture. Is ogenic strains, with or without dsRNA, were submitted to virulence tests ag ainst the whitefly Bemisia tabaci strain B. In contrast to findings for som e phytopathogenic fungi, these dsRNA fragments did not cause hypovirulence P. fumosoroseus.
