Impact of olfactory and visual cues of soybean aphid on the metabolism and stress resistance of Orius sauteri (Poppius)

•We used Enzyme-Linked Immunosorbent Assay detecting enzyme activity in O. sauteri.•Orius sauteri could sense stimulus cues from soybean aphids by smelling and sighting.•Pyruvate kinase activity was stimulated after O. sauteri smelled the soybean aphid.•Visual stimulation stimulated HSP70 expression preferentially than olfactory.•Enzyme activity regulation by olfactory and visual increasingly approached over time.
