| This study was conducted in sharqat region during the season 2013 , on some leaf shape Populus euphratica . The results indicate of the population density of insect fluctuated during this period and reached its peak the end of May 16 , 14 egg/ larva respectively with temperature 28,56 and relative humidity 42,2 % on shape ovate first generations while was less population density of insect during period the end of June and from early July on shape cordate and reniform1,1egg/ larva respectively with temperature 34,15, 33,40 and relative humidity 21, 22%.second generations reached densities of the insect its peak on shape ovate 13 , 11 egg/ larva respectively with temperature 22,41 and relative humidity 34,6% during October . while was less population density of insect during the end November on shape cordate and reniform 0 , 0egg/ larva respectively with temperature 15,45 and relative humidity 75% .The statistical analysis showed it was correlation plus with temperature and correlation negative with relative humidity the eggs while was correlation negative with relative humidity and there not correlation with temperature the larvae.. | ||
