Influence of different floral feeds on the biological attributes of Chrysoperla carnea (stephens)

The pre-oviposition period was reduced to 3.10 days in case of adults fed on flowers of Hibiscus rosasinensis followed by flowers of Cannabis sativa (3.70 days) as against 8.30 days obtained on Cicer arietinum. The oviposition period was reduced to 12.40 days in the case of control followed by Cicer arietinum (14.90 days). The highest % hatchability (97.00%) was observed when they fed on flowers of Ricinus communis compared to control (44%). There was many-fold increase in fecundity (eggs/female) when female fed on floral feed of R. communis (310.90), Brassica campestris (297.70) as against the lowest 20.60 eggs/female in adult fed on control. Lowest longevity of males (23.70 days) and females (28.20 days) was observed when fed on control followed by Cicer arietinum and longest longevity of males (52.80 days) was observed when fed on R. communis and Zea mays and longest longevity of female (55.90 days) fed on floral feed R. communis.
