Online published on 18 April, 2020. Abstract Field experiment was conducted at Malayalthanpatti Village, Madurai District, Tamil Nadu during March to June 2018 to evaluate three IPM modules viz., Farmer's practice (M1), Recommended practice (TNAU)(M2), IPM suggested module (M3) for the management of key insect pests of bitter gourd viz., aphid, whitefly, leaf eating caterpillar, fruit fly, hadda beetle and pumpkin beetle. The suggested module (M3) comprising basal application of neem cake @ 250 kg/ha, foliar application of NSKE 5% at 20 DAP, installations of Barrix trap (25 traps/ha) @ 30 DAP, foliar spray of Bt @ 2g/l of water @ 40 DAP, foliar spray of chlorantraniliprole 150ml/ha at 60 DAP led to minimum population of aphids (2.08/3 leaves), whitefly (2.29/3 leaves), leaf eating caterpillar (0.65/plant), hadda beetle (0.82/plant) and pumpkin beetle (0.73/plant). Fruit fly infestation was also minimum (6.80%) in the suggested module (M3) giving maximum yield (28.89 t/ha).
