[en] The predator Episyrphus balteatus (DeGeer) (Diptera, Syrphidae), efficient in the biological control against the aphids is able to perceive most of the volatile compounds from plants and aphids. All these semiochemicals define the different relationships between the three trophic levels (plant-phytophagous-predator) and directly help E. balteatus, as other predators and parasitoids, to locate their prey. In this context, our study highlights the importance of plant and aphid semiochemicals in the foraging behavior of the predator E. balteatus.
