The experiment was conducted in the laboratory under the Department of Entomology, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from April to July, 2011 to find out the eco-friendly management of pulse beetle, Callosobruchus chinensis Linn. on stored mungbean using some promising botanicals viz. dried leaf powder of neem @ 2.5 g/kg mungbean grains (T1), bishkatali @ 2.5 g/kg mungbean grains (T2), marigold @ 2.5 g/kg mungbean grains (T3), dholkolmi @ 2.5 g/kg mungbean grains(T4), chopped garlic bulb @ 1.0 g/kg mungbean grains (T5) along with control (T6). The experiment was laid out in Completely Randomized Design with four replications. From this study, it was observed that the treatment T1 comprised with dried leaf powder of neem @ 2.5 g/kg mungbean grains reduced the highest percent of grain infestation by number and weight (43.12% & 41.72%, respectively) over control than other botanicals. Conversely, T5 reduced the highest percent of adult emergence (43.65%) and grain content loss (49.91%) over control, but increased the highest percent of seed germination (25.65%) over control. Therefore, it can be concluded that dried leaf powder of neem @ 2.5 g/kg mungbean grains was the most effective control measure applied against pulse beetle, C. chinensis on stored mungbean.
