The studies on evaluation of IPM modules for the management of pin worm, Phthorimaea absoluta (Meyrick) were carried out on tomato cultivar, Arka Abhedh. The experiment was carried out under naturally ventilated polyhouse condition during 2021-22 at College of Horticulture, Mudigere. The experiment was laid out in Randomized Complete Block Design, comprising four treatments with five replications. Observations were recorded at 10 days intervals. Module 1 consisting of seed treatment with imidacloprid 48 % FS @ 7g/kg of seeds, seedling dip with imidacloprid 17.8 SC @ 0.5 ml/l, collection and destruction of infested leaves, installation of sticky traps at 30/1000 m2 area, installation of sex pheromone traps 20/1000 m2 area and spraying of chlorantraniliprole 18.5 SC @ 0.3 ml/l, spinoteram12 SC @ 1.25 ml/l followed by flubendiamide 480 SC @ 0.3 ml/l proved to be better in reducing tomato pin worm population under naturally ventilated polyhouse condition.

From the present investigation, it could be concluded that Module 1 consisting of seed treatment with imidacloprid 48 % FS @ 7g/kg of seeds, seedling dip with imidacloprid 17.8 SC @ 0.5 ml/l , collection and destruction of infested leaves, installation of sticky traps at 30/1000 m2 area, installation of sex pheromone traps 20/1000 m2 area and spraying of chlorantraniliprole 18.5 SC @ 0.3 ml/l, spinoteram12 SC @ 1.25 ml/l followed by flubendiamide 480 SC @ 0.3 ml/l proved to be better in reducing tomato pin worm population under naturally ventilated polyhouse condition.
