Impact of bio-chemical parameters on pigeonpea varieties against egg laying, fecundity and viability of pulse beetle, Callosobruchus chinensis (Linn.)
B.S. Chandel, D.S. Bhadauria
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.
