Abstract

This paper reports the morphological characteristics of immatures and adults of Typhlodromus (Anthoseius) bagdasarjani Wainstein & Arutunjan, 1967 (Phytoseiidae) collected from plum trees, Prunus domestica L. (Rosaceae), infected with two-spotted spider mites (Tetranychidae) in the Hamedan region, Western Iran. The genders of the deutonymphal stage can be determined by the number of paired setae in the opisthogaster (eight in females vs. five in males).
