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.
