Among the several pulses in the human diet, the chickpea (Cicer arietinum L.) is the most abundant source of protein and plays a significant role in the agricultural economy of our nation. The main insect pest, Callosobruchus chinensis L., damages grain quality by polluting it and lowering its nutritional value. It also causes significant losses during storage. The goal of the current study was to determine how C. chinensis grows and develops on Bengal gramme (variety-Radhey) and to assess how seed protectants affect the fecundity and hatching percentage of C. chinensis. Applying neem leaf powder at a rate of 15 g/kg of seed resulted in a significantly maximal reduction in fecundity, or 9.30 eggs/female. In the grains treated with neem leaf powder, the hatching percentage is 15.10 percent; this is significantly different from the untreated rate of 88.58 percent.
