Online published on 21 January, 2023. Abstract The study was conducted under laboratory conditions at Department of Entomology Lab, College of Agriculture, JNKVV, Jabalpur (MP) during 2019–20. The screening of chickpea varieties viz. JG 63, JG 16, JG 12, JG 14, JG 24, JG 36, JG 11, JAKI 9218 and RVG 201 were studied against the pulse beetle infestation. The varieties, JG 36 and JG 12 were most preferred host for egg laying, while least preferred varieties were JG 11 and JAKI 9218.The maximum mean adult emergence was in JG 36 and minimum in JAKI 9218. The maximum seed damage up to (69.33%) was observed in JG 36, while minimum (43.33%) damage occurred in JAKI 9218. The weight loss was highest in JG 36 with (63.33) per cent and was lowest in JAKI 9218 (38.67%). Germination per cent was recorded in varieties JAKI 9218 showed the average highest infected seed germination (24.67%), while variety JG 36 showed lowest infected seed germination (7.33%). And Germination per cent was recorded in varieties JG 14 showed the average highest Healthy seed germination (92.67%), while variety RVG 201 showed lowest Healthy seed germination (74.67%). Overall on the basis of above parameters JAKI 9218 was most tolerant variety and JG 36 was most susceptible variety. Top Keywords Pulse beetle, Screening, Chickpea, Seed germination, Stored pest.
