A research was conducted on the response of eight mash (Vigna mungo) genotypes NCH-9-9, NCH-3-4, NARC-MASH-3, CHAKWAL-MASH-97, NCH-7-5, MASH UROOJ, NARC-MASH-1 and NCH-10-1 to pulse beetle, Callosobruchus maculates under laboratory conditions. Two sets of experiments, No-Choice and Free-Choice tests were carried out and the results were evaluated on the basis of fecundity, development period, adult emergence, adult weight, damage and weight loss in grains. In No-Choice test, NARC-Mash-1, NCH-3-4 and Mash-Urooj showed good results with minimum grain damage 17.82± 0.56%, 18.27±0.66% and 18.43± 0.55%, respectively. While maximum damage (23.86± 0.52%) was shown by NCH-7-5. In Free-Choice test, NCH-10-1 performed best with 12.29± 0.45% grain damage followed by NARC-Mash-3 (13.70± 0.47%), NCH-3-4 (14.06± 0.20%) and Mash-Urooj (17.33± 0.59%). While NARC-Mash-1 showed maximum grain damage (23.45± 0.49%) contemporary to its result in NO-Choice test. One genotype NCH-9-9 showed almost similar results 22.74± 1.15% and 22.88± 0.57% in both No-Choice and Free-Choice tests. NCH-3-4 and Mash-Urooj performed well under both types of tests. Damage was positively correlated with the number of eggs, weight loss and adult emergence but negatively correlated with developmental period and 100 grain weight.
