Abstract:
Highest mean number of hatching / egg survival was recorded in Artificial diet (86.50±2.90) followed by Aphids feeding (75.25±2.28). Highest mean number of larval survival/ no.of pupae was observed in Artificial diet (73.00±2.48) followed by Aphids feeding with larval survival/ no.of pupae for parent (67.00±3.93). Maximum pupal weight was observed in Artificial diet (0.07±1.79) followed by Aphids feeding with pupal weight (0.06±2.06). Highest pupal survival rate was observed in Artificial diet (75.25±1.49) followed by Aphids feeding with pual survival rate (65.50±2.39). Highest male sex ratio was recorded in Artificial diet (25.00±0.70) followed by Aphids feeding with male sex ratio (21.50±0.95). Maximum female sex ratio was observed in Artificial diet (48.50±3.17) followed by Aphids feeding with female sex ratio (37.75±0.85). Longest incubation period was noted in Aphids feeding having incubation period (4.00±0.40), while shortest incubation period was recorded in Artificial diet (3.25±0.25). Longest larval period (in days) in Aphids feeding was (8.00±0.40), although shortest larval period was recorded in Artificial diet (7.00±0.25). Longest papal period was recorded in Aphids feeding was (5.25±0.47) whereas, shortest pupal period was recorded in Artificial diet (4.25±0.25). More egg laying rate was noted for Artificial diet (2006.30±64.91) followed by Aphids feeding with egg laying rate (1830.00±32.40).
