Field efficacy of two modules tested during December 2011 to March 2012 for the management of major insect pests of groundnut revealed that bio-intensive module for groundnut [vermicompost 2 t/ha + neem cake 250 kg/ha + bio-fertilizers 2 kg/ha + NPK (8.5:34:54 kg/ha); Chrysoperla zastrowi @ 50,000 eggs/ha (3 releases on 20, 30, 40 DAS); Trichogramma chilonis + T. japonicum @ 6.25 cc/ha (3 releases on 37, 47, 57 DAS); Helicoverpa armigera NPV and Spodoptera litura NPV @ 500 ml/ha (4 sprays 40, 50, 60, 70 DAS); neem gold 0.15% @ 1.5 ml/lit (4 sprays 25, 40, 55, 70 DAS)] was effective in reducing the incidence of both the sucking pests (aphids & leafhopper) and defoliators (leafminer, S. litura & H. armigera) of groundnut and recorded the highest yield of 1836 kg wet pods/ha.
