An experiment was conducted in the field, Department of Entomology, RVSKVV, College of Agriculture, Gwalior (M.P.) in Kharif-2018 and 2019. Efficacy of bio-pesticides against sucking insect pests of okra. Experiment was laid out in Randomized Block Design with eight treatments. Biopesticides used in the experiments were Beauveria bassiana @ 0.5 kg/ha, Verticillium lacanii @ 1.0 kg/ha, Neem oil 5% @ 2.5 litre, Neem leaf extract 5% @ 25 kg/ha, NSKE 5% @ 25 kg/ha, Garlic clove extract 5% @ 25 kg/ha and Panchgavya 3% @15 litre/ha. All the biopesticides treatments were found significantly effective in reducing the population of aphid over control (untreated) plots. The treatments V. lecanii was found to be significantly effective against aphids population followed by NSKE 5%, garlic clove extract 5% and neem oil 5%. Whereas, panchgavya 3% was found least effective in both the years. The highest fruit yield (119.56 q/ha) was recorded in NSKE 5% followed by B. bassiana and neem oil 5%. Whereas, minimum fruit yield was recorded in panchgavya 3% in both years. The highest net profit (27,128 Rs/ha) was obtained from the plots treated with B. bassiana followed by NSKE 5% (25,938 Rs/ha) and maximum benefit ratio in the B. bassiana (1:14.13) followed by V. lecanii (1:8.36), NSKE 5% (1:8:11) and garlic clove extract 5% (1:6.78).
