- Abstract
Entomopathogenic fungi are eco-friendly microbial pesticides to manage different insect pests of economic importance and as a substitute to conventional synthetic insecticides, present study evaluated pathogenicity of four indigenous (Chinese) fungal isolates, viz., Isaria fumosorosea (SP-535 Isolate), I. fumosorosea (G-800 Isolate), Beauveria bassiana (Y-132 Isolate) and Metarhizium anisopliae (Qin-13 Isolate) against green peach aphid, Myzus persicae and pea aphid, Acyrthosiphon pisum. The findings of pathogenicity revealed that I. fumosorosea (SP-535) isolate caused relatively the highest mortality (96.65%) of M. persicae followed by 90.00% in A. pisum at highest dose rate (1x108) whilst I. fumosorosea (G-800) strain showed less mortality potential with values of 88.85 and 84.45% against M. persicae (88.85%) and A. pisum (84.45%) at highest dose rate (1x108) at 25°C. B. bassiana (Y-132) isolate caused 82.21 and 81.10% mortality against M. persicae and A. pisum, respectively, Least mortality rates of 39.88% and 36.78% in M. persicae and A. pisum respectively were caused by M. anisopliae (Qin-13 Isolate) at 20°C. Further, I. fumosorosea isolates was comparatively more virulent than other isolates and M. persicae was found more susceptible to all four fungal isolates than A. pisuam. Pathogenicity of tested fungal isolates was highest at 25°C than on 20 and 30°C. It is concluded that these fungal isolates have a good potential to be developed as new bio-pesticides.
