This study was conducted in aestivation and hibernation sites of Sunn Pest and in wheat fields in Southern Syria. The distribution type of Sunn Pest Population in aestivation and hibernation sites is collective. In the first site (AL-Jabia hill) the average of Sunn Pest aggregated in the hill top was 23.6±2.2 adults/m², while it was 15.2±1.6 adults/m² at the hill base. In second site (AL-Harra hill) the average of Sunn Pest aggregated in the hill top and hill base were 23.1±2.5 and 14.05±1.5 adults/m² respectively and this showed that adults prefer to spend summer aestivation in mountain areas under trees and it is rarely found in regions were there is no trees. The situation was opposite during winter hibernation, in the first site (AL-Jabia hill) the average of Sunn Pest aggregated in the hill top was 10.25±0.9 adults/m², while it was 19.1±1.9 adults/m² at the hill base and in second site (AL-Harra hill) the average of Sunn Pest aggregated in the hill top and hill base were 11.1±0.9 and 20.05±2.2 adults/m² respectively, that is advert the insects moved downward toward the hillside and to the base to escape from hard conditions in winter
