The investigation was carried out during kharif 2010-2011 and 2011-2012 in order to know the effect of different IPM module on insect pests of soybean. Significantly lower population of (2.54 larvae/ mrl) H.armigera, per cent pod damage (4.23%) by H.armigera were observed in MAU module. The minimum larval population of semilooper (3.62 larvae/mrl), S.litura (2.64 larvae/mrl) and per cent leaflet damage (6.71%) due to leaf miner, the minimum per cent defoliation (10.49%) due to defoliators were observed in chemical control followed by MAU module.

Significantly lower population of (2.54 larvae/ mrl) H.armigera, per cent pod damage (4.23%) by H.armigera were observed in MAU module. The minimum larval population of semilooper (3.62 larvae/mrl), S.litura (2.64 larvae/mrl) and per cent leaflet damage (6.71%) due to leaf miner, the minimum per cent defoliation (10.49%) due to defoliators were observed in chemical control followed by MAU module.
