Though chillies found to be affected by several insect pests, chilli thrips and mite are the most destructive pest and is also attacked by the storage pest viz. cigarette beetle Lasioderma serricorne. The present investigation was carried out to study the biology of cigarette beetle in stored chillies. The average egg, larval, pupal, adult, total developmental period was 8.0, 24.0, 8.0, 14.0, 54.0 days in mundu chilli pods, while in buttermilk chilli pods was 6.0, 21.0, 5.50, 11.0, 43.50 days respectively. The maximum hatchability, survival per cent of larvae and pupae, adult emergence and fecundity was 60.13, 62.87, 74.93, 78.29 per cent and 93.85 no. of eggs / female respectively in buttermilk chilli pods while minimum was in mundu chilli pods 34.50, 49.41, 59.42, 58.60 per cent and 71.62 no. of eggs / female respectively.
