The economically and ecofriendly safe technology in sustainable agriculture such as habitat manipulation by growing of intercrops in groundnut was studied against the major insect pest of groundnut. The combination of biorational pesticides especially the microbial based and use of newer insecticides molecules as poison bait studied at Department of Entomology, University of Agricultural Sciences, Dharwad and at farmers field in Ranebennur taluka of Haveri district during 2022-2024.The results revealed that, the groundnut + pearl millet intercrop significantly reduced the mean population of Spodoptera litura (Fab) by recording only 0.77 larvae/ meter row length (mrl), which was superior to other combinations. Groundnut intercropped with cowpea, sorghum, and foxtail millet also effectively managed pest populations by recording 1.80, 1.20, and 1.22 larvae/mrl respectively. The intercrops foxtail millet + pearl millet minimized leaf miner infestations by documenting 0.94 and 0.91 larvae per plant respectively.Lowest leaf damage was recorded in groundnut + pearl millet (24.45%), followed by groundnut + foxtail millet (25.39%). Groundnut + cowpea and groundnut + sunflower exhibited higher defoliation rates of 28.42% and 28.68%, respectively. Further the lowest populations of leafhoppers were recorded in groundnut + pearl millet (1.33 per top three leaves) and groundnut + foxtail millet (1.36 per top three leaves). The same combination was also equally found good in keeping thrips population significantly lower than all others by recording 1.25 and 1.38 thrips per terminal buds, respectively.Laboratory evaluations of biorational pesticides showed that spinosad 45 SC at 0.2 ml/l achieved cent percent larval mortality of S. litura within three days. Combination of commercial Bt with pongamia oil @ 1 g+2 % and Beauveria bassiana + pongamia oil @ 2 g+2 % and Metarhizium releyi + pongamia oil @ 2 g+2 % were also effective by documenting 83.50, 81.67 and 76.67 per cent of larval mortality, respectively. Among bait treatments, spinosad 45 SC documented the highest larval mortality of 93.33% at 48 hours.Field trials indicated that spinosad 45 SC at 0.20 ml/l as a foliar spray was the most effective (0.30larvae /mrl) and minimal leaf damage (9.03%). The combination of commercial Bt and pongamia oil also proved effective (10.28%). In terms of yield, the combination of commercial Bt and pongamia oil recorded the highest pod yield (2420 kg/ha) and haulm yield (2060 kg/ha).Among the newer insecticide formulations, novaluron 5.25% + indoxacarb 4.50% SC @ 0.88 ml/l was the most effective in managing S. litura (0.30 larvae/mrl and leaf miner (0.54 larvae/plant.Whereas, thiamethoxam 12.6 % + lamda cyhalothrin 9.50 % ZC@ 0.30 ml/l was proved to be effective against sucking pest like leaf hopper and thrips by showing least incidence of leaf hoppers 1.25 /top three leaves and 1.72 thrips per terminal buds. In terms of yield, novaluron 5.25% + indoxacarb 4.50% SC@ 0.88 ml/l resulted in the highest pod (2690 kg/ha) and haulm yield (2378 kg/ha)
