Abstract: The cigarette beetle, Lasioderma serricorne (F.) is a serious pest of stored turmeric, therefore, an experiment was conducted to study their life history in turmeric powder. The female insect laid their eggs singly on the surface of turmeric powder. Eggs were pearl white, oval shaped with spines on the single end of an egg. The larvae were scarabaeiform, creamy white in colour and uniformly covered with fine hairs. They have completed four larval instars and pupated inside the cocoon made from food materials. The mean incubation, larval, pre-pupal, pupal and the developmental period were 9.40 ± 0.40, 28.20 ± 1.45, 4.50 ± 0.34, 9.50 ± 0.65 and 51.60 ± 2.06 days, respectively. The percentage of egg hatching, pupation, adult emergence, fecundity and sex ratio were 76.75 ± 3.00, 89.79 ± 1.42 and 89.73 ± 1.27, 26.70 eggs and 1:1.1, respectively. The adults were reddish brown beetles with a head deflexed down which is at right angle to the body giving humpback appearance. The adult longevity and total life cycle of male, female were 11.20 ± 0.55, 12.40 ± 0.60 and 62.80 ± 2.06, 64.00 ± 2.26 days, respectively.
