| Abstract | ||
| Studies were conducted at the college of Agriculture, University of Mosul to evaluate the susceptibility of some poplar species to infestation by the poplar worm, Epinotia abbreviana F.Results indicated a significant differences between means of leaf area ,leaf thickness ,chlorophyll percent ,water content and number of hairs ( leaf) of the poplar species in the mean of the number larva poplar species .The study appear the increase in the mean leaf area were lead to an increase in the number of larva on the leaf .Mean of leaf area of euphratica poplar, Populus euphratica , black poplar,Populus nigra and Americana poplar, Populus deltoids was reached (45 ,91 ,44 ,25 ,53 ,14 ) with larva number (1 ,6 ,2 ,03 ,2 ,90 ) larva \ leaf , respectively . The study shown that the mean of thickness leaf with larva reached ( 0.179 , 1.6, 0.161 , 2.03 and 2.90 , 0.178) respectively. Increase of the chlorophyll in poplar leaf lead to larva increased . Mean of chlorophyll percent with number of larva for poplar species reached (1.370 , 1.6 , 1.380 , 2.03 , 1.391 , 2.90 ) respectively . The results of present study showed variation of mean water couteuts with a number of hairs for leaf poplar were reached (39.88 ,38.84 ,42.51, 32.10, 42.64 ,35.36 ) respectively . The results appeared that the euphratic poplar showed higher susceptibility to infestation and larva number was more the euphratic poplar 4.02 larva/ leaf , with chlorophyll percent and water content reached 1.39 , 42,64 respectively, followed black poplar,Populus nigra 2.75 larva/ leaf , whereas the American poplar,Populus deltoides was least susceptibility reached 1.72 larva/ leaf with chlorophyll percent and water content 1.37 , 39.88 respectively. | ||
