An Integrated Pest Management (IPM) module [installation of pheromone traps @ 40/ha after 15 days of sowing, spray application of azadirachtin @ 0.0006 % (Groneem 0.15 EC, 40 ml /10 litre of water) on appearance of 1st instar H. armigera larvae, application of HearNPV @ 250 LE /ha after 10 days azadirachtin (neem based) spray, and spray of endosulfan @ 0.07 % (endosulfan 35 EC, 20 ml /10 liters of water) at the time of pod formation on 50 % plants] was evaluated during rabi 2009-10 against Helicoverpa armigera infesting chickpea (Cicer arietinum) in comparison to recommended schedule (RS) [spray of fenvalerate 0.02 % (fenvalerate 20 EC, 5 ml/10 litre of water) at the time of flowering on 50 % plants and spray of endosulfan 0.07 % (endosulfan 35 EC, 20 ml /10 liters of water) at the time of pod formation on 50 % plants] and control on the basis of different parameters viz., larval population, pod damage at green pod and harvest stage, per cent parasitism by a larval-pupal parasitoid, Carcelia illota and seed yield. IPM module recorded significantly lower larval population (0.38 larva /plant) and damage to pods at green pod (6.55%) and maturity (10.18%) stage. A higher per cent parasitism (08.22%) by C. illota , a larval pupal parasitoid of H. armigera was recorded in IPM plot as compared to RS plot indicating its usefulness in conservation of this natural enemy. IPM module recorded highest seed yield (1667 kg /ha) and net realization (` 26,846 /ha). The highest net incremental cost benefit ratio was in RS (1:14.26) followed by IPM module (1:7.47).
