Abstract

تم جمـع 87  عينـة تربـة مركبـة مـن حقـول اللـوزيات في اللاذقية-سورية خلال شهري أيلول وتشـرين أول لعـام 2006 مـن أجل التحري عن وجود النيماتودا الممرضة للحشرات وبالتالي إمكانية استغلالها في المكافحة الأحيائية. أُتبعت  طريقة الطعم  باستخـدام العمر اليرقي الأخير  من دودة الشمع الكبرىGalleria mellonella للكشف عن هذه النيماتودا. تبين أن 15% من المجموع الكلي للعينات كانت إيجابية، حيث تـم الحصـول على13 عـزلة. وبناءاً على الشكل الخارجي للنيماتودا والقياسات المورفولوجية  للطور المُعدي (IJ)Infective Juvenile  والذكـر تم التعرف على الجنسين Steinernema وHeterorhabditis ، حيث تم تحديد نوع واحد من الجنس Steinernema  هو S. cubanum  بنسبة 7.6% من إحدى العزلات، ونوع واحد من الجنس Heterorhabditis  هو H. bacteriophora  من باقي العزلات  وبنسبة 92.4%.

وتبين انتشار النيماتودا الممرضة للحشرات في التربة ذات القوام اللومي واللومي الرملي،  وعدم تواجدها في التربة ذات القوام الطيني في الحقول المدروسة.

A total of 87 composite soil samples were collected from stone-fruit orchards  in Lattakia, Syria during September and November 2006. Samples were tested for the presence of entomopathogenic nematodes (EPNs) by baiting method with last larval instar of the greater wax moth Galleria mellonella. Positive soil samples were 15% of total samples, where thirteen isolates of EPNs were extracted. EPN isolates were identified morphologically and morphometrics for infective juvenile (IJ) and male. One of the isolates was identified as Steinernema cubanum (7.6%)  and the others isolates were identified  as Heterorhabditis  bacteriophora (92.4%). Entomopathogenic nematodes occurred in loam and loamy sand soil, and were not present in clay soil.
