C. S.  aEffects of double-stranded RNA on virulence of Paecilomyces fumosoroseus (DeuteromycotinabHyphomycetes) against the silverleaf whitefly, Bemicia tabaci strain B (Homoptera: Aleyrodidae).h[electronic resource]  c2000  aBands of double-stranded RNA (dsRNA) were detected in three out of twelve isolates of Paecilomyces fumosoroseus. Identity of these bands was confirmed by RNAse, DNAse and S1 nuclease treatments. The cure of dsRNA for one isolate (P92) was successfully carried out for a single conidium subculture. Isogenic strains, with or without dsRNA, were submitted to virulence tests against the whitefly Bemicia tabaci strain B. In contrast to findings for some phytopathogenic fungi, these dsRNA fragments did not cause hypovirulence in P. fumosoroseus.  abiological control  aBrazil  aControle Biológico  aBemicia tabaci  aBrasil  aEntomogenous fungi  aFungo entomopatogenico  aInseto praga  aPaecilomyces fumosoroseus  aPest insects1 aSOSA-GOMEZ, D.R.1 aFARIA, M.
