Abstract To screen high pathogenicity entomopathogenic fungi against the tobacco whitefly，Bemisia tabaci（
Gennadius），the virulence of seven isolates of Beauveria bassiana，three isolates of Metarhizium anisopliae，and
one isolate of Paecilomyces fumosorseus were identified in this study．The results showed that Canada No.1（B．bassiana）
was the most virulent isolate against B．tabaci．The pathogenicity of Canada No.1 to egg and nymph stages
of B．tabaci were also investigated．Results showed that Canada No.1 had no virulence to the eggs，but had high
virulence to the 2nd，3rd and 4th nymph，and the virulence was decreased with the increase of nymph age．
