Abstract:
Two experiments were conducted to study the biology of cigarette beetle, Lesioderma
serricorne (F.) and its damage assessment in different spices in the laboratory of the
department of Entomology, Sher-e-Bangla Agricultural University, Dhaka-1207
during March to July, 2015. Experiments were laid out in a Completely Randomized
Design (CRD). In the study of biology, it was revealed that the adult female laid 112-
160 eggs with an average of 138.80 eggs and the ovipositional period, incubation
period, larval period, pupal period and adult longevity of Cigarette beetle were 4.00 ±
0.02 days, 6.67 ± 0.03 days, 14.00 ± 0.09 days, 8.33 ± 0.03 days and 9.67 ± 0.05 days,
respectively. fenugreek (Methi), coriander (Dhania), cumin (Jira), fennel (Mouri),
celery (Rhadhuni), carom (Ajowan) and Dried red chilli were used as experimental
materials in the second experiment. The experiment concerning damage assesment of
the above spices by cigarette beetle, indicated that the adult longivity, larval and pupal
duration and adult emergence of cigarette beetle was varied in different spices. The
study revealed that the percent infestation was highest in cumin 25.67 %, 66.43% and
100% at 1st, 2nd and 3rd generations, respectively and no infestation occured in celery
(Radhuni) and carom (Ajowan) spices.
