Chickpea (Cicer arietinum L.), also known as Bengal grams or grams, is the second most important legume in Asia, North Africa, and Mexico. More recently, it has also become an important legume crop in the northern United States, Canada, and Australia. It is grown on an average of 13,544,400 hectares worldwide. 8.8 million tons produced. India is the largest producer of chickpeas in the world with a share of at 71.0 and 67.2% of the total area (9th place) 6 million hectares) and production (8.8 million hectares) and (FAOSTAT, 2013) ^[5]. Several biotic and abiotic constraints limit chickpea production and productivity, and pests are a major constraint for increasing chickpea production and productivity (Sharma 2005 and Yadav et al., 2006. Sharma et al., 2011) ^{[13-14, 19]}. Five chickpea genotypes resistant – RVSSG – 63, RVSSG 8102, Pusa Chickpea Manav, CG Lochan Chana, H 12-55 commercial cultivars were sown across four planting dates between October - January at monthly intervals during 2022 - 23 post rainy seasons under field conditions. The experiment was laid out in randomized block design (RBD) with three replications for each genotype, in a plot of six rows 3 m long (with a spacing of 60 cm between the rows and 10 cm between plants with in a row). Data were recorded one meter row length. At Seven days intervals in each planting. The incidence of Helicoverpa armigera (Hubner) larvae was highest in the crop sown in October (52.47 larvae per meter row length) in RVSSG 8102. lowest in the December sown crop (14.46 larvae per meter row length) in RVSSG 63. In the 2022 – 23 cropping season. The interaction effects were significant. Second Highest number of Helicoverpa armigera (Hubner) larvae were recorded on CG Lochan chana (44.13 larvae per meter row length), followed by H12-55 (14.52 larvae per meter row length) and RVSSG 63 (8.60 larvae per meter row length). The lowest incidence of Helicoverpa armigera (Hubner) larvae was recorded in H12-55 (5.52 larvae per meter row length).
