Abstract: Chickpea is an important source of protein, carbohydrate, fibres, oil, calcium, phosphorus, magnesium, iron, zinc, β-carotene, unsaturated fatty acids. In addition, improves soil fertility by fixing atmospheric nitrogen in to soil. High protein content invites the Insect pests more which is probably the main bottleneck in legume production. It is recognized that immediate implementation of ideal IPM packages is not possible in Indian conditions, so chemical insecticides are still required as a last resort to manage severe pest infestation. In present studies population of spiders in chickpea field was investigated against insecticide treatments in a field experiment during 2015-16. Two foliar applications of various treatments were given and it was observed that the population of spiders was higher in control plot ranging between 1.0 to 2.64 per plant after first spray while the population range was observed 1.0 to 2.34 after second spray. Immediately after application the treatment had clearly reduced the pest population and favored the spider population, subsequently the population kept decreasing with time.
