Abstract:

The bio efficacy of selected bio control agents viz. Metarhizium anisopliae, Beauveria bassiana, Lecanicilium lecanii and Chrysoperla zastrowii against Amrasca biguttula biguttula was studied under insectary, Department of Agricultural Entomology, TNAU, Coimbatore, India during 2014-2015. Three different concentrations viz., 1 x 104, 1 x 106, 1 x 108 spore/ml of these each entomopathogenic fungus were tested to evaluate the effective concentration. Among the three concentrations, 1 x 108 spores/ml of L. lecanii recorded the highest mortality of 85.00%against leafhopper withLT50 value of 115.37 hours and low LC50 value observed in L. lecanii (1.83x104 spores/ml). In pot cultures studies, Among the bio-control agents, L. lecanii was the most effective in reducing cotton leafhoppers with average per cent mortality of 69.17 followed by C. zastrowii, B. bassiana and fungi combination with average per cent mortality of 55.83, 48.33 and 46.67 respectively.
