The olfactory orientation of the aphidophagous ladybird Coccinella septempu
nctata L. was assessed in a Y-tube olfactometer and a choice arena. The res
ponse of the predator to 22 plants, aphid prey and conspecifics was tested.
The ladybird was attracted to the odour of chopped Berberis vulgaris L. le
aves, and of Tripleurospermum inodoratum (L.) Sch.-Bip. flowerheads, and ma
les were attracted to females. Methanol extracts of B. vulgaris leaves were
also attractive.
