Abstract:
The mean incubation period of Z. bicolorata varied from 4.48 to 6.7 days on plant parts of P. hysterophorus. The significantly shortest larval duration (9.4 days), the higest growth index (8.75), the highest% pupation (82.00) and shortest pupal period to the tune of 9.80 days was observed in those larvae which fed on tender leaves of P. hysterophorus. The significantly highest pupal duration (15.80 days) and lowest adult emergence (64.60%) was observed on flowers of P. hysterophorus. The life cycle duration of male and female beetles of Z. bicolorata was found to be lowest on flowers of P. hysterophorus to the extent of 46.80 and 49.60 days respectively.
