Abstract: Studies have been conducted in cotton fields of the Southeastern Anatolia Region, Kızıltepe District of Mardin Province and Akçakale District of Şanlıurfa Province. Cotton types with different number of hairs in leaves were used in the study. Similar results were obtained in the study at both locations. Very close association has been found between the sucking insects and number of hairs on cotton leaves. While the Thrips tabaci Lind. And Bemisia tabaci Genn. Developed better in varieties with leaves having hairs, they developed less in varieties with leaves that did not have hairs. In contrast, Asymmetrasca decedens (Paoli) and Empoasca decipiens (Paoli) have produced population that was 19 folds more abundant in varieties with leaves that did not have hairs as compared to varieties with leaves having hairs.
