The field trial was laid out in the premises of Insectary, Entomology Section, College of Agriculture, Nagpur, during the rabi season of 2013-14. The experiment was laid out in randomized block design (RBD) with three replications and eight treatments including control (water spray). The observations were recorded on average per cent pod damage caused by Helicoverpa armigera (Hubner) and average grain yield of chickpea. Cumulative effect of various treatment on natural enemies i.e. coccinelids and spiders was studied after 14 days after spraying revealed that the treatment control (water spray) invited highest population of natural enemies to the tune of 1.08 no./plant.

The experiment was laid out in randomized block design (RBD) with three replications and eight treatments including control (water spray). The observations were recorded on average per cent pod damage caused by Helicoverpa armigera (Hubner) and average grain yield of chickpea. The observations on percent pod damage at harvest stage indicated that pod damage ranged from 18.64% to 38.85%. The treatments spinosad 45 SC 0.01% (18.64%) and quinolphos 25 EC 0.05% (21.24%) recorded lowest pod damage and afforded the best protection against Helicoverpa armigera (Hubner) by reducing 18.64 per cent and 21.24 per cent pod damage respectively on harvest as compared to ...

The observations were recorded on average per cent reduction in the larval population were recorded. Considering all the parameters, the treatment spinosad 45 SC 0.01 % recorded highest 76.17 per cent reduction in the larval population with minimum pod damage (18.64 %) and produced 15.23 q/ha yield
