The relationship of altitude, cardinal direction and plant species occupied by the sunn pest Eurygaster integriceps Puton (Heteroptera: Scutelleridae), during the aestivation period were determined. Studies were carried out on plant species (Astragalus dipthterites Fenzl., Noea spinosissim Moq., Acantholimon sp. and Astragalus sp.), at 3 altitudes (1600 –1800; 1800–2000; 2000–2200 m), and in three directions (North, South, and East) from the overwintering sites on Nemrut Mountain, Adıyaman Turkey. According to the results, there were significant interactions of plant species x altitude, plant species x direction and altitude x direction. With respect to the species x altitude interaction, the most adults were found on N. spinosissim at altitudes of 1800–2000 m, and the least numbers were found on Astragalus sp. at the altitudes of 1600–1800 m. Considering the species x direction interaction, the most adults were found on N. spinosissim plants at the southern areas of overwintering sites, and the least numbers of adults were found on Astragalus sp. at the eastern sites. In the case of the altitude x direction interaction, the most adults were found in the southern areas of overwintering sites at 1800–2000 m, and the least numbers were found at the altitudes of 1600–1800 meters at the northern direction of overwintering sites.
