                Abstract

The objective of this study was to determine the pathogenicity of Beauveria bassiana against Hyphantri acunea(Drury) larvae under the laboratory conditions. The H. cunea larvae were collected in Georgia and entomopathogenic fungi (PaF04, PaF09, PaF76) were isolated from Pristiphora abietina larvae in the previous study. Applications were performed by immersing the larvae in the conidial suspension(106 conidia/ml) for 30 s. All fungal isolates tested were pathogenic to the H. cunea larvae causing mortality between 90±5,77% and 96,6±3,33%. Mortality caused by B. bassiana was not significantly different between the isolates (p<0,05). LT50 values varied between 2,36±0,31 and 2,53±0,17 days. The present results suggested that B. bassiana has an excellent potential for biological control of H. cunea larvae. Additional field research is needed to determine effect of B. bassiana is at controlling H. cunea larvae in the field conditions.

Key words: Hyphantria cunea, Beauveria bassiana, Biological control, Entomopathogenic fungi.
