Botanicals are safer and healthier measures to control insect pests of stored grains. Studies were conducted to evaluate the insect repellency, and mortality effect of leaf powder of Piper betle on Corcyra cephalonica (Rice moth). Various concentrations (w/w) of leaf powder were treated with rice for the study. The results showed an increase in insect repellency with increase in concentration of powder treated. When fourth instar larvae were reared in leaf of P. betle admixtured rice significant reduction in larvae to pupal development was observed. There was significant increase in larval mortality with increase in concentration of leaf powder administration. All these results indicate that P. betle is a good source of bioactive principles against the stored grain pest Corcyra cephalonica.
