Popis:	The effects of parasitized aphids as food on development, growth, and survival of fourth stadium larvae were assessed in three species of aphidophagous ladybirds, Coccinella septempunctata Linne, Harmonia axyridis (Pallas), and Propylea japonica (Thunberg) in relation to development of parasitoid larvae. The effects of eating aphids, parasitized aphids or mummies on larval performance were the same in the three species except for survival: parasitized aphids were good food for the three species, while developmental time of fourth stadium larvae of the three species was significantly longer when fed on mummies than when fed on aphids or parasitized aphids, and mummies also produced a negative effect on growth of the three species. Survival of C. septempunctata larvae was significantly lower when offered mummies rather than aphids or parasitized aphids as food, though H. axyridis and P. japonica were not affected by the type of prey supplied in terms of survival, indicating that mummies were not a suitable food for the three species, in particular for C. septempunctata.
