The functional significance of E-β-Farnesene: Does it influence the populations of aphid natural enemies in the fields?

► The stable component E-β-Farnesene (EβF) extracted from Matricaria chamomilla L. ► We reported practicability of EβF on aphid natural enemies in Chinese cabbage fields. ► Natural enemies on plants and in yellow traps were analyzed synchronously. ► The EβF could reduce cabbage aphids by attracting natural enemies in the fields.
