Abstract

A study was conducted in Syrian Coastal region, to identify parasitoids accompanying the olive leaf midge, Dasineura oleae. Results showed many species of the ecto-parasitoids of Hymenoptera which parasitize on the third larval instar and pupae of olive leaf midge Dasineura oleae F. Löew during 2013 and 2014 in the Syrian Coast. These ecto-parasitoids belong to the families Eupelmidae and Eulophidae. An identification key for families of Hymenoptera was used for the Parasitoids depending on meso pleuron, number of tarsus segments and form of Prepectus. There are three species of the genus Eupelmus sp., of which E. urozonus Dalm was recorded. For the first time, the species Zeytinus hatayensis (Eulophidae) was recorded depending on the diagnostic characteristics of the male. Also, there is an endo-parasitoid of Hym.:Platygasteridae which parasites on the second larval stage of D. oleae. In addition, the species of the endo-parasitoid, Platygaster demades Walker.1835 was firstly identified and recorded according to the diagnostic characteristics of the female.

تعريف المتطفلات المرافقة لذبابــــة أوراق الزيتـــون

Dasineura oleae F. Löew ( Diptera ,Cecidomyiidae)

المسجلة في بعض مناطق الساحل السوري

أجريت دراسة لمعرفة المتطفلات المرافقة لذبابة أوراق الزيتون Dasineura oleae F. Löew وتوصيفها في المنطقة الساحلية من سوريا، بينت نتائج الدراسة وجود عدة أنواع من المتطفلات الخارجية تابعة لرتبة غشائية الأجنحة Hymenoptera تتطفل على يرقات العمر الثالث وعذارى ذبابة أوراق الزيتون D. oleae خلال عامي الدراسة 2013 و2014 في الساحل السوري. تتبع هذه الأنواع للفصائل Eupelmidae  وEulophidae. تم التعرف على هذه المتطفلات وفق المفتاح التصنيفي لفصائل رتبة غشائية الأجنحة وذلك اعتماداً على بلورا الصدر الأوسط وعدد عقل الرسغ وشكل الـ Prepectus. حيث وجدت ثلاثة أنواع تتبع للجنسEupelmus sp. (Eupelmidae) وقد حدد نوع واحد منها هـو النـوعDalm.  urozonus.E. كما تم ولأول مرة خلال الدراسة تعريف النوع Zeytinus hatayensis Eulophidae)) وذلك اعتماداً على الصفات التصنيفية المميزة للذكر لهذا النوع، كما سجل متطفل داخلي على يرقات العمر الثاني للذبابة يتبع لرتبة غشائية الأجنحة فصيلة Platygasteridae وتم تعريفه ولأول مرة في سوريا و هو Platygaster demades Walker.1835 وذلك من خلال الصفات التصنيفية لأنثى المتطفل.
