Abstract The zoophytophagous mirid predator Nesidiocoris tenuis and the ectoparasitoid Stenomesius japonicus are important biological control agents for several agricultural pests including invasive leafminer, Phthorimaea absoluta , a destructive pest of Solanaceous crops especially tomato in sub-Saharan Africa. However, little is known about how feeding by N. can influence tritrophic interactions plant. Here, we tested hypothesis that phytophagy would olfactory between host plant pest, predator, parasitoid. In olfactometer assays, P. females adults were both attracted to constitutive volatiles released Whereas avoided -infested plants, S. induced volatiles. coupled gas chromatography-electroantennographic detection (GC-EAD) recordings intact volatiles, antennae detected eight components, whereas seven components which identified GC-mass spectrometry (GC-MS) as terpenes green leaf (GLVs). Dose-response bioassays revealed responses varied with composition concentration blends individual compounds from N -induced Females showed no preference an eight-component blend formulated repellents hexanal, ( Z )-3-hexenyl butanoate, δ-elemene On other hand, attractants E )-2-hexenal, )-3-hexenol, methyl salicylate, β-phellandrene, )-caryophyllene. Likewise, seven-component δ-elemene, )-caryophyllene Our findings suggest there potential use GLVs manage insects interaction.
