Online published on 27 December, 2023. Abstract The study on biology revealed that the duration of egg laying, incubation, larval period, pupal period and total life cycle of T. castaneum lasted for 6.40, 6.60, 30.80, 5.20 and 49.0 days, respectively. The best preferred the groundnut (ICGS-76) seed the most damaging 10.01 per cent of the seeds and leading to 1.21 per cent loss in weight under storage while coriander (local cultivar) was found the least preferred with 0.33 per cent seed damage and 0.01 weight loss.
