Abstract:
A study was conducted in the Biocontrol laboratory, Department of Entomology, College of Agriculture, OUAT, Odisha during 2020-21 to determine the effects of different artificial adult diets on adult longevity, oviposition period and fecundity of green lacewing, Chrysoperla zastrowi sillemi (Esben-Peterson). Six adult diets i.e. T1 (Water: Honey: Protinex:: 40: 40: 20), T2 (Water: Honey: Castor pollen:: 40: 40: 20), T3 (Water: Honey: Protinex: Castor pollen:: 40: 40: 10: 10), T4 (Water: Molasses: Protinex:: 40:40:20), T5 (Water: Molasses: Castor pollen:: 40: 40: 20) and T6 (Water: Molasses: Protinex: Castor pollen:: 40: 40: 10: 10) were evaluated along with control (T7=Water: Honey:: 50: 50). T1 was adjudged as the best adult diet which produced maximum male longevity of 35.18 days with 8.41% increase over control, maximum female longevity of 48.07 days with 10.13% increase over control, highest oviposition period of 25.45 days with 13.81% increase over control and highest fecundity of 333.47 with 19.81% increase over control. T1 was closely followed by T2 with the respective data of 34.89 days and 6.90%, 47.38 days and 8.55%, 24.94 days and 11.54% and, 325.20 and 16.83%.
