Abstract:

Efficacy of entomopathogenic fungi, Beauveria bassiana (2 x 106 conidia/g), Metarhizium anisopliae (1 x 109 conidia/g) and Lecanicillium lecanii (2 x 107 conidia/g) @ 5 g/kg with vegetable oils (2 ml/kg) viz. Sunflower, Groundnut oil was studied against lesser grain borer, Rhyzopertha dominica, in paddy. The highest adult mortality of R. dominica was recorded with Metarhizium + Groundnut oil (81.57%) followed by Beauveria + Groundnut oil (78.54%) when compared to Groundnut oil (65.28%) alone at 15 DAT. Progeny buildup recorded at 180 DAT was found to be less with Beauveria + Groundnut oil (118.33) followed by Metarhizium + Groundnut oil (121.33) when compared to control (517.00) and was superior over all other treatments. Similarly, less per cent weight loss was recorded with Beauveria + Groundnut oil (17.59%) followed by Metarhizium + Groundnut oil (19.01%) when compared with control (50.09 %) at 180 DAT. A high per cent reduction in progeny was recorded with Beauveria + Groundnut oil (77.11%) followed by Metarhizium + Groundnut oil (76.53%) compared to control. The next better were recorded with Beauveria + Sunflower oil (73.56%), Lecanicillium + Sunflower oil (72.66%) and Metarhizium + Sunflower oil (71.37%) when compared to control at 180 DAT. A high per cent reduction in weight loss was recorded with Beauveria + Groundnut oil (64.88%), followed by Metarhizium + Groundnut oil (62.05%). The next better were recorded with Beauveria + Sunflower oil (60.03%), Metarhizium + Sunflower oil (56.50%), and Lecanicillium + Sunflower oil (51.61%) when compared to control at 180 DAT.
