Abstract

The aim of this study was to investigate how the primary and secondary host plants in the fruit orchards affect the interactions of aphids and their parasitoids in northwest Turkey during spring and summer 2020 and 2021. In total, 67 tritrophic aphid-parasitoid-host plant interactions, including new association records for Europe and Turkey, were obtained from 16 parasitoid species from the subfamily Aphidiinae (Hymenoptera: Braconidae) reared from 25 aphid species (Hemiptera: Aphididae) on 22 primary and secondary host plants in the fruit orchards. Also, we evaluated the effect of the primary and secondary host plants on the parasitoids, aphids and their interactions. We revealed that the species richness and the values of the biodiversity indices of the parasitoids and aphids were significantly higher on the secondary host plants than the primary host plants. Similarly, the aphid- parasitoid interactions on the secondary host plants showed greater diversity than the primary host plants. The results of this study clearly show that the interactions of parasitoids and aphids in the fruit orchards were more diverse on the secondary host plants compared to the primary host plants.
