Abstract: Investigation were carried out to determined the impact of Bio-chemical characters of promising varieties of pigeonpea, Cajanus cajan Linn. against Callosobruchus chinensis Linn. The promising genotypes viz. PUSA–84, PRABHAT, MANAK, AMAR, PUSA-33, ICPL-151, UPAS-120, JAGARTI, TYPE-7, PUSA-9, BAHAR, and TYPE-21 of pigeonpea were obtained from IIPR, Kalyanpur, Kanpur. The egg laying was  observed minimum (132.71 eggs) on MANAK, closely followed by BAHAR (146.65 eggs) and ICPL-151 (183.60 eggs) and higher number of eggs were 270.60 on TYPE-21, 251.54 on PRABHAT, 233.78 on JAGARTI at 5 days, which were significantly different among themselves. Similar trend of egg lying was persisted even at 10 days after the release of the insects.
