Abstract :This research was conducted to determine the phytoseiid species on walnut trees in Samsun Province, Turkey in 2018. Most of the surveys were done in unsprayed orchards. A total of nine phytoseiid species were collected - Euseius finlandicus , E. gallicus , E. stipulatus , Kampimodromus aberrans , Neoseiulella tiliarum , Phytoseius finitimus , Typhlodromus ( Anthoseius ) rapidus , Typhlodromus ( Anthoseius ) sp. and Amblyseius ( andersoni ?) sp. Euseius finlandicus was the most abundant species, followed by Phytoseius finitimus . Mite density was twice as high on the lower surface as on the upper surface of leaves. These nine species represent a substantial local genetic resource with the potential to improve the efficacy of biological control programs.
