Abstract: Allothromblum triticium Zhang, 1995 and Erythraeus (Erythraeus) ankaraicus Saboori, Cobanoglu and Bayram, 2004 (Acarina: Prostigmata: Trombidiidae, Erythraeidae) samples were collected on Mealy plum aphid Hyalopterus pruni (Geoffroy, 1762) (Homoptera: Aphididae) which was found on the secondary host Phragmites austrialis L. (Poaceae) during 2001-2002, in Ankara-Turkey. A. triticium was found in a higher density than E. ankaraicus on aphids. Larvae of A. triticium peaked in mid June while E. ankaraicus peaked at the beginning of July on H. pruni. It was observed that these species preferred the thorax of aphids as attachment site. !n the current study, density of each mite species exist on the host, their preference to the biological development stages of aphids and seasonal abundances were evaluated.
