Resumo: Direction and symmetry of intraguild predation (IGP) between all developmental stages of the aphidophagous Harmonia axyridis Pallas and Coccinella undecimpunctata L. were characterized. Our results revealed that H. axyridis predation level was significantly higher than C. undecimpunctata and eggs were the more vulnerable developmental stage. Significantly asymmetric IGP on eggs occurred after the second and fourth larval stages of H. axyridis and C.undecimpunctata, respectively. Asymmetric IGP on pupas exclusively occurred in the presence of the fourth larval stage of H. axyridis.
