Abstract
Cigarette beetle, Lasioderma serricorne (F.)
(Coleoptera: Anobiidae) is one of the key storage pests that damage the leaves
of tobacco. L. serricorne is a significant pest in the food and industry
of tobacco in many areas of the world. A great amount of physical and chemical control
methods have been established up to now in order to confirm the operational
protection of stored tobacco and its products from pests. In this study, 23
different host foods (10 spices, 6 cereals, 4 oil seeds, tobacco leaves, biddi
tobacco and Rayon thread), were selected to explore their behavioural responses
against L. serricorne. As a result, it was found that among spices
(Fennel, Coriander, Carum, Cumin, Turmeric, Chilli, Black Mustard, Black
pepper, Amchur, Ginger), percent adult emergence was maximum in fennel (68.50%)
and minimum in black pepper (5.75 %) whereas the developmental period was
observed longest on black pepper (61.25 days) and shortest on fennel (35.50
days). In cereals (Wheat, Crushed Wheat, Barley, Rice, Sorghum, Maize), highest
adult emergence was recorded on crushed wheat (33.75) and lowest emergence was
observed on maize whereas the mean developmental period was highest on maize
(53.20 days) in comparison with other cereals. Apart from cereals and spices, amongst
four oil seeds viz., mustard, groundnut, cottonseed and castor seeds, the
percent adult emergence recorded was highest on groundnut (35.75) seeds whereas
the lowest adult emergence was recorded on mustard. In chewing tobacco and bidi
tobacco, the adult emergence was 40.25 and 37.50 percent, respectively,
whereas, developmental period was longer when insects were fed with bidi
tobacco (52.77 days). When L. serricorne was reared on rayon thread, the
adult emergence was very poor (only 3.50 percent) with longer developmental
period.
