Abstract AR
نفذت الدراسة في غابة نینوى خلال الموسمین 2004 و 2005.
تصيب هذه الحشرة القوع الفراتي.
نتيجة لتغذية الحورية الحديثة الفقس يتكون تورم في نسيج الفرع بالقرب من قاعدة برعم, يحدث التزاوج خلال الأسبوع الأول من أيار.
بلغ متوسط فترة ما قبل وضع البيض, وضع البيض و ما بعد وضع البيض (1.8 ± 0.74 و 5.30 ± 0.57 و 2.00 ± 0.49) يوما على التوالي.
تضع الأنثى البيض بشكل مفرد و على كافة أجزاء الورقة الحديثة التكوين و الناضجة.
بلغ متوسط عدد البيض للأنثى الواحدة 21.80.
بلغت نسبة الفقس 80% و بلغت النسبة الجنسية 2:1.
تقضي الحشرة سباتها الشتوي على هيئة حوريات في العمر الثاني.
وجد أن هذا البسليد له جيل واحد في السنة.
تشير الدراسة البيئية إلى أن متوسط عدد البيض, و الحوريات و البالغات لهذا النوع من البسليد كان أكثر كثافة في التداخل بين الواجهة الجنوبية للشجرة و الواجهة الجنوبية للغابة و الارتفاع العلوي للشجرة, إذ بلغ متوسط أعدادها (100.00 و 64.48 و 57.40) على التوالي.
Abstract EN
This study was conducted on poplar bud psyllid in Ninevah during the years 2004 and 2005.
For the first time Egeirotrioza justa Burk and Laute has been studied and recorded in Iraq.
The poplar bud psyllid Egeirotrioza justa Burck and Laute attacks Populous euphratica trees and as a result of feeding by newly nymphs, small galls are formed on the twig tissues near the buds.
The adults appeared on the trees during May to July.
Mating usually occurred during the first week of May, mean periods of pre–oviposition, oviposition and post-oviposition (1.

Egg laying took place singly on the leaf petiols, and on bouth services and margins of mature as well as the tender young leaves and twigs.
The average number of eggs laid per female was 21.80, hatching of eggs was 80 % and sex ratio was 1 : 2.
This species hibernates as a second nymphal instar.
This insect has one generation per year.
The study indicated that the south direction of a tree from south side of the forest and at a height more than 3m for trees were represented high average number of eggs nymphs and adults 64.
