| Abstract | ||
| Laboratory and field experiments were conducted to determine the Influence of some Leaves Morphological and Biochemical Traits of the more famous cotton cultivars in Iraq(Ashure, Marsomy4, Coker and Lashata) to the Cotton Aphid Aphis gossypii Golv.. also determined the population density and seasonal presence to pest and evaluate the yield loss. The Results Showed that Marsomy4 C.V was the most infected host for aphid followed by Coker and Lashata , the mean number of the pest was 0.843,0.625,0.229 insect/leaf respectively, and the reason of this Results was had Marsomy4 c.v the least number of gossypol gland(52.14 gland/cm2 ) and highest leaf area (98.21cm2 ), number of hairs was high (43.10 hair/cm2 ), high tannin concentration and lamina thickness),while Ashure C.V was the least infected host for aphid , the mean number of the pest was0.158 insect/leaf because this cultivar had the highest leaf lamina thickness (0.525 micron) and least tannin concentration (0.155mg/gm), and low number of hairs (34hair/cm2 ). | ||
