Abstract: The pest population in Akçakale and Ceylanpınar districts was 5.3 individuals/50 sweep- nets as a maximum, number of damaged small boll is 4.8 boll/plant and 7.6 boll/sweep net as a maximum, and number of damaged small boll number was 5.7 boll/plant, respectively. The pest population in 2003 developed slowly and reached only the level of 4.5 individuals /50 sweep-nets. While one generation completed within 55.63 days under controlled conditions including 16 hours of light and 8 hours of darkness, 65±5% relative humidity at 25±1 C temperature; the generation completed within 24.7 days at 30±1 C. Maturation at the short period of time at high temperature (30±1 C) and having a high capacity of egg-laying (122 eggs/individual) have led to the conclusion of C. pallidus can be a problem in case it is seen in cotton plantations at the flowering stage and it should be fought against; however, if mature individuals of C. pallidus are seen in cotton fields at stages that bolls have completed their development, there will be no need for struggle.
