[en] Combining intercropping with the release of semiochemicals may strengthen biological control of aphids as a push-pull strategy that simultaneously repels aphids and attracts their natural enemies. This hypothesis was tested in the Henan Province of China in 2016 where aphids, their natural enemies and mummies were trapped and observed on crops in three treatments: wheat-pea strip intercropping solely (control), intercropping combined with the release of E-β-farnesene (EBF) and intercropping combined with the release of methyl salicylate (MeSA). Each
treatment was repeated four times. The abundance of aphids throughout the growing season (9 weeks between March and May) was significantly decreased and the abundance of natural
enemies and mummies were significantly increased in treatments with releases of semiochemicals compared to intercropping solely. The effect was stronger with MeSA than with EBF on the control of Rhopalosiphum padi and pea aphids as well as on the attraction of lacewings and hoverflies. Indeed, lacewings and hoverflies were on average twice more numerous in MeSA than in the other treatments. These results show that combining wheat-pea
intercropping with the release of EBF or MeSA can significantly reduce aphid density and attract their natural enemies and that this effect is strengthen with MeSA when compared to EBF.
