Volatile Exchange between Undamaged Plants - a New Mechanism Affecting Insect Orientation in Intercropping
Figure 4
Aphid olfactory responses to synthetic blends of volatile organic compounds of exposed and unexposed potato.
Responses of winged Myzus persicae in olfactometer experiments when presented with synthetic blends based on headspace collections of onion-exposed (treatment) and unexposed potato (control). Synthetic blends were at 1/100, 1/10, 1x, 10x or 100x the original concentration of volatiles identified in potato headspace. Error bars indicate ± SEM. * P≤0.05 Wilcoxon test.
