Abstract: A field experiment was conducted on <em>Helicoverpa armigera</em> (Hubner) in chickpea during <em>Rabi</em>, 2016- 17 at B.E.D.F.(Research Farm)/APEDA, S.V.P.U.A &amp; T, Meerut,-250 110 (U. P.) <em>H. armigera</em> is a major pest of chickpea and weather factors are the major regulating causes for the insect pest population under field conditions. Among all the treatments the minimum pod infestation was 4.78 per cent recorded with Methomyl 40% SP@ 1.6g/l., treatment which was significantly superior from the rest of the treatment, the maximum grain yield of 22. 45 q/ha was recorded with Methomyl 40% SP@ 1.6g/l with highest cost benefit ratio. Among the bio pesticides treatments, <em>Ha</em> NPV 2x10⁹pob/ml @ 250 LE/ha was recorded with highest grain yield as 19.01 q/ha with highest cost benefit ratio of 1:14.15
