Efficacy of Bio-Pesticides against Leaf Miner, Liriomyza sp. of Field Pea

On the effectiveness of biopesticides against Liriomyza spp., the pea leaf miner, field research was done. at an experimental field, Organic Research Farm Karguwan Ji, Department of Entomology, Institute of Agricultural Sciences, Bundelkhand University, Jhansi (Utter Pradesh) during Rabi Season of 2022-2023. Many biopesticides, such as castor oil, panchgavya, neem seed kernel extract (Crude extract), verticillium lecanii (2x108 cfu), neem oil, garlic bulb extract, and Bacillus thuringiensis (5% WP). Pea leaf miner Liriomyza Spp. was significantly different in the biopesticide-treated plant compared to the untreated control, according to the experimental data. Among them, the treatment of Beauveria bassiana (8.90 larvae/5 plant) was found in significantly more effective against the pest as compared to other bio-pesticides Bacillus thuringiensis, NSKE, Neem oil, and Verticillium lecanii were found moderately effective and proved significantly superior over Castor oil, Panchgavya and Garlic bulb extract proved significantly less effective among the bio-pesticides evaluated against pea leaf miner Liriomyza spp.
