Abstract
Pulse beetle, Callosobruchus chinensis (Dhora) is a serious pest of stored grain products; it attacks mainly on the pulses, cereals and different types of grains. The damage due to this pest affects the germinative ability and nutritive value of the seed. In the present study, we observed the oviposition behavior of Callosobruchus chinensis on different pulses and cereals. For this purpose rearing of pulse beetle was done in controlled laboratory conditions i. e.temperature of 37± 2șC and 40± 5% relative humidity and adult beetles was used in the experiment.Callosobruchus chinensis reared on five different pulses i.e. Phaseolus vulgaris (Kidney beans), Lens culinaris (Masoor or black gram), Cicer arietinum (White grams or chickpea), Vigna radiata (Mung beans) and Vigna unguilata (Cowpea, black eyed bean or white lobia) and five different cereals Triticum aestivum (wheat), Zea maize (Maize), Pennisetum glaucum (Pearl millet), Hordeum vulgre (barley) and Avena sativa (Oat) selected on the basis of their nutritional values. The maximum number of eggs was recorded on kidney beans (147.67±0.58), mung beans (132.00±2), moderate on cow pea (78.00±2) and least on white gram (66.67±2.52) and black gram (63.00± 1.73) whereas in the case of cereals the highest preference of oviposition was recorded on maize (13.67±1.53) and wheat (7.67±1.15) while least preference on barley (5.67±0.58) and millet (2.3±0.58) and minimum on aot (0). So, the result showed significant differences among the oviposition rate on different pulsesand cereals. ANOVA test was applied to compare the results.
