The research was conducted in Al- Mokhtaria Research Station, Agricultural Research Center, Homs, Syria during season 2016. The efficacy of some plant extracts (Melia azedarach L., Schinus molle L., Styrax officinalis L., Eucalyptus camaldulensis De., Nerium oleander L.) were tested against Stephanitis pyri F. (Tingidae: Heteroptera) and compared with traditional insecticides (Cypermethrin, Chlorpyrifos Ethel).

Research summary
تناولت الدراسة تقييم كفاءة بعض المستخلصات النباتية في مكافحة حشرة نمر الأجاص (Stephanitis pyri) في محطة بحوث المختارية بحمص خلال موسم 2016. تم اختبار خمسة مستخلصات نباتية وهي الأزدرخت، القلقل المستحي، الأصطرك، الأوكاليبتوس، والدفلة، ومقارنتها مع مبيدين حشريين تقليديين هما سايبرمترين وكلوربيرفوس ايتيل. أظهرت النتائج أن مستخلص الأصطرك كان الأكثر فعالية في مكافحة الحوريات والحشرات الكاملة بنسبة فعالية بلغت 94.9% و92.2% على التوالي، يليه كلوربيرفوس ايتيل بنسبة فعالية 94.3% و91.8%، ثم مستخلص الأزدرخت بنسبة فعالية 93.7% و90.8%. بينما كان مستخلص الدفلة الأقل فعالية بنسبة 59.2% و56.5%. أشارت النتائج الإحصائية إلى وجود فروق معنوية بين المعاملات المختبرة بعد 1، 3، 7 و14 يوم من الرش. أوصت الدراسة بإمكانية استخدام مستخلصي الأصطرك والأزدرخت في برامج الإدارة المتكاملة للآفة كبدائل بيئية مناسبة للمبيدات الكيميائية التقليدية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة نحو البحث عن بدائل بيئية للمبيدات الكيميائية التقليدية في مكافحة حشرة نمر الأجاص. ومع ذلك، يمكن توجيه بعض الملاحظات النقدية لتحسين البحث. أولاً، كان من الممكن توسيع نطاق الدراسة لتشمل مواسم زراعية متعددة لتقييم تأثير العوامل المناخية المختلفة على فعالية المستخلصات النباتية. ثانياً، لم يتم التطرق إلى تأثير هذه المستخلصات على الأعداء الحيوية المفيدة، وهو جانب مهم في برامج الإدارة المتكاملة للآفات. أخيراً، كان من الممكن تحسين الدراسة بإجراء تجارب ميدانية على نطاق أوسع تشمل مناطق زراعية مختلفة لضمان تعميم النتائج.

The toxic effect of some insecticides (Amitraz, Amitraz + summer oil, Abamectin, Abamectin + summer oil) and plant extracts (Melia azedarach L., M. azedarach + summer oil, Schinus molle L., S. molle + summer oil) were tested on the predator of pea r psyllae insect Anthocoris nemoralis F. and the parasite Trechnites psyllae R. in the Mokhtaria research station, agricultural research center at Homs during the season 2011.
The efficacy of insecticide and plant extracts were tested against beet flea beetle, Chaetocnema tibialis (Illiger) during 2008 and 2009 seasons. Six pesticides were evaluated against beet flea beetle, results showed that Cyperino gave the highest effective percentage (90.88) followed by Cypermethrin (90.69%), in comparison with Nimadol (49.35%) after two weeks of treatment. Four plant extracts were evaluated against beet flea beetle in comparison with Sopreen. Results showed that Melia azedarach L. extract gave the highest effective percentage (60.81) followed Styrax officinalis L. leaves and branches and Capsicum annuum L. extracts by 31.35, 28.44 and 16.57, respectively, in comparison with Sopreen (58.55%) after 7 days of treatment. Percentage of efficacy decreased gradually by increasing the period of exposure after treatment for plant extracts from 63.19% after 3 days to 51.80% after 10 days of Melia azedarach L. extract. Whereas the efficacy percentage of Sopreen increased from 41.67% after 3 days to 74.57% after 10 days of treatment.
This investigation carried out in 2012-2013,in department of plant protection- Damascus Unv., to study the effect of ethanol and water extracts of Allium sativum L., Inula viscos L., Thymus vulgaris L. and Melia azedarach L., in inhibition mycelium growth of fungi Alternaria alternata and Fusarium oxysporum and compared with fungicides (carbendazim and chlorothalonil) on PDA in the laboratory. The result showed that ethanol extracts of studied species gave significant inhibition to growth fungi compared with the control. The ethanol and water extract of the Allium sativum gave the superior effect inhibition to F. oxysporum where gave 100% inhibition at 600 and 1000 mg/l. at respectively, and gave100% inhibition to A. alternata at 1000 mg/l. Followed with the ethanol extract of Inula viscos. While, the ethanol and water extract of the Melia azedarach gave the lowest inhibition to growth study fungi. Where didn’t gave 100 % inhibition to F. oxysporum and A. alternata at 1000 mg/l. On the other hand, the ethanol extract of Thymus vulgaris gave moderate inhibition to F. oxysporum, while the inhibition of A. alternata was little. The ethanol extract of tested plants gave the superior effect inhibition to both fungi compared with water extracts. On the other hand, the obtained results showed that carbandazim gave the superior inhibition for F. oxysporum ,where gave 100% inhibition at concentration 120 mg/l. While the fungicide chlorothalonil gave the lowest inhibition to F. oxysporum. At contrast, the fungicide chlorothalonil gave the highest inhibition to A. alternata at used concentration. Where cause 100% inhibition at 150 mg/l. On the other hand, Effect of plant extracts and fungicides increased with increase of concentrate. We can arranged the effect of plant extraction at the values (ED50): Allium sativum L., Inula viscos L., Thymus vulgaris L. and Melia azedarach L., Therefore we recommended to use the ethanol extract of the Allium sativum L., Inula viscos L. as environment friendly fungicides.
This investigation was conducted at the Pome and grapevine Division in Sweida governorate in 2014-2015. Four introduced pear cultivars (Anjou, Bartlett, Red Bartlett and Beurre Bosc) were studied, through fruiting and growth organs, fertility, average of fruit weight, and the yield at P< 0,05.
20 local and introduced varieties of pear grown in Sweida during 2007 to 2010 were assessed in terms of flowering time, maturity time, accurate morphological characterization for shoots, leaves, flowers and fruits and fruit chemical analysis (tota l soluble solids, total sugar and tetratable acidity) as well as to determine firmness of fruit flesh and tree yield. Results showed that flowering time was at mid April in most varieties, and the varieties were divided into three groups according to their mature date: early varieties maturated during July, mid varieties maturated during August and late varieties maturated during September. However, A variety of Conference was required artificial ripening.
