ABSTRACT The overall results indicated that different biological and life fecundity parameters of C. chinensis varied significantly when reared on different varieties of pigeonpea. The mean incubation period was 4.26 days on BSMR-853 followed by BDN-711 (4.35 days), BDN-708 (4.41 days) and BDN-716 (4.65 days). The significantly highest egg hatch was observed on BSMR-853 (96 per cent) followed by BDN-711 (93 per cent), BDN-708 (92 per cent) and BDN-716 (88 per cent). The significantly shortest larval-pupal duration was noticed on BSMR-853 (19.93 days) followed by BDN-711 (20.66 days), BDN-708 (21.84 days) and BDN-716 (22.20 days). Significantly highest growth index was noticed on BSMR-853 (2.75) followed by BDN-711 (2.70), BDN-708 (2.60) and shortest on BDN-716 (2.43). The significantly minimum total developmental period was observed on BSMR-853 (24.17 days) followed by BDN-711 (25.02 days), BDN-708 (26.26 days) and maximum on BDN-716 (26.81 days). Significantly highest adult emergence was observed in the case of those grubs which were reared on BSMR-853 (96.84 per cent) followed BDN-711 (95.73 per cent), BDN-708 (94.49 per cent) and lowest on BDN-716 (88.83 per cent). The significantly highest adult longevity was noticed on BSMR-853 (10.70 days) followed by BDN-711 (10.34 days), BDN-708 (9.69 days) and BDN-716 (9.68 days). Significantly lowest total life cycle duration was noticed on BSMR-853 (34.87 days) followed by BDN-711 (35.37 days), BDN-708 (35.95 days) and BDN-716 (36.47 days). The significantly highest oviposition period was observed on BSMR-853 (7.20 days) followed by BDN-711 (6.80 days), BDN-708 (6.00 days) and BDN-716 (5.60 days). The fecundity (eggs per female) was highest on BSMR-853 (88.20) followed by BDN-711 (82.60), BDN-708 (74.60) and BDN-716 (69.40). |
