Effect of different adult diets on development of the green lacewing Chrysoperla carnea Stephens (Neuroptera: Chrysopidae) was studied. Four adult diets namely; (A) honey distilled water, (B) pollen grains added to honey distilled water, (C) royal jelly added to honey distilled water, (D) royal jelly and pollen grains added to honey distilled water were tested. Treatment D gave the best results for egg hatching (89.3%), larval survival rate (92.6%), pupal survival rate (95.1%), adult emergence (98.1%) and overall developmental period (egg- adult) (77%). As well, it gave the optimum results as shortest pre-ovipositional period (3.6 days), a long ovipositional period (14 days) and the shortest total developmental duration (19.3 days). Highest values of Ro (the net reproductive rate) , r ^sub m^ (the intrinsic rate of natural increase) and e ^sub rm^ (the finite rate of increase ) were obtained when the predator was fed on treatment D. Rate of survival ((Lx) and maximum ovipositional rate / female /day(Mx) were high using diet D. Sex ratio deviated towards females in treatment D. [PUBLICATION ABSTRACT]
