تصيب السونة كلا من محاصيل القمح والشعير والشوفان والشيلم , كما لوحظت الأصابة
على دوار الشمس و الكتان , االبرسيم , وقد تصيب الذرة.
تظهر اعراض الأصابة على النباتات مع بدء هجرة الامهات من أماكن البيات وهبوطها في حقول القمح والشعير .
حيث تلاحظ الاعراض التالية :
على الأوراق:
تفضل الحشرة الأوراق الغضة , وتمتص العصارة النباتية مما يؤدي إلى ظهور اختناقات في مكان الامتصاص , وبالنتيجة التفاف وتماوت في القسم العلوي للورقة .
على الساق والسنابل :
اصابة الساق الرئيسية على نبات القمح مما يتسبب بظاهرة الفراغ الكلي او الجزئي للسنبلة.
على الحبوب :
نقص في وزن الحبوب وتجعد الحبة وانخفاض في نسبة الإنبات , اما عند تصنيع طحين الحبوب الخاص بإنتاج الخبز تكون النتيجة تدني مواصفات الطحين الناتج عن تخرب الغلوتين .

Poetry can be found all over the world in public spaces. Some examples mentioned include poetry plaques on walls in Trois Rivieres, Quebec, verses etched into concrete slabs in Wellington, New Zealand, and a mobile poetry van that drives around Santa Fe, New Mexico offering people a chance to write poetry. Poetry stands and decorations on buildings featuring local poets' works can also be found in many communities.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
A computer-based key for identifying 30 genera of plant parasitic nematodes is described. The key uses Lucid software and is multi-access rather than dichotomous, allowing users to choose observable characters without being limited by couplet structure. Character states like stylet length and shape, body size and shape, and tail morphology are used. Images help non-specialists identify specimens. The key aims to aid identification of nematodes in New Zealand for management and biosecurity purposes.
