Summary: The biology, reproductive variables and population growth indicators of Harmonia axyridis (Pallas, 1773)(Coleoptera: Coccinellidae) fed on three diets, namely Cinara atlantica (Wilson, 1919) (Hemiptera: Aphi-didae), Brevicoryne brassicae (Linnaeus, 1758) (Hemiptera: Aphididae), and frozen eggs of Anagastakuehniella (Zeller, 1879) (Lepidoptera: Pyralidae), were evaluated. With all three diets, birth rate washigher than mortality, resulting in positive rmvalues and thus indicating population growth. Under theconditions used in the experiments, H. axyridis was able to survive, develop and reproduce normally.This demonstrates that are different kind of food that can be essential for supporting the reproduction ofsome species of Coccinellidae, but not with the same optimization of preferred prey.
