The Peach flatheaded rootborder Capnodis sp. is the most important insect which attack stone-fruits in Syria, Entomopathogenic fungi Metarrhizium sp. and Paecilomyces sp. were isolated from larvae of Capnodis tenebrionis (Coleoptera: Buprestidae) attacking peach. This study was conducted to reveal the pathogenicity of the two fungies against the neonate larvae of Peach flatheaded rootborder, The two fungies were used in a concentration 106 conidia/ml, dipping the larvae in fungal suspension ,then it was put in apricot branches by approximately 1 cm diameter, and mortality rates two weeks after inoculation with the suspension of each of the fungi was 95% for Metarrhizium sp. and 85% for Paecilomyces sp.

Research summary
تتناول هذه الدراسة تقييم فعالية فطريين ممرضين للحشرات، هما Metarrhizium sp. و Paecilomyces sp.، ضد يرقات حشرة حفار جذور الخوخ Capnodis tenebrionis. تعتبر هذه الحشرة من أخطر الآفات التي تهاجم أشجار الفاكهة ذات النواة في سوريا. تم عزل الفطريين من يرقات الحشرة وتم اختبار تأثيرهما على اليرقات حديثة الفقس بتركيز 10° كونيديا/مل. أظهرت النتائج أن معدل الوفيات بعد أسبوعين من المعاملة بلغ 95% للفطر Metarrhizium sp. و85% للفطر Paecilomyces sp.، مما يشير إلى فعاليتهما العالية في مكافحة هذه الآفة. تعتمد الدراسة على غمر اليرقات في معلق الفطر ومن ثم وضعها في أغصان المشمش بقطر حوالي 1 سم لتقييم تأثير الفطريين على معدلات الوفيات.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لأنها تقدم حلاً بيولوجيًا لمكافحة آفة خطيرة تهدد المحاصيل الزراعية. ومع ذلك، يمكن توجيه بعض الانتقادات البناءة لتحسين البحث. أولاً، لم يتم التطرق إلى تأثير الفطريين على البيئة المحيطة أو الكائنات غير المستهدفة، وهو جانب مهم يجب أخذه بعين الاعتبار في الدراسات البيئية. ثانيًا، لم يتم تقديم معلومات كافية حول الظروف البيئية التي تم فيها إجراء التجارب، مثل درجة الحرارة والرطوبة، والتي قد تؤثر على فعالية الفطريين. أخيرًا، يمكن أن تكون الدراسة أكثر شمولية إذا تم اختبار تأثير الفطريين على مراحل حياة أخرى من الحشرة، وليس فقط اليرقات حديثة الفقس.

A Study was carried out to evaluate the ability of the methanolic, hydro and oily extractions of anise seeds (Pimpinella anisum L.) to inhibit the growth of the pathogenic fungi Fusarium oxysporum and Aspergillus niger. The results showed a good in hibition ability of the alcoholic and hydro extractions on the growth of the studied fungi. The inhibition ability differed due to the used concentrations. When the methanolic extraction was used by concentrations (2, 4, and 6) mlg/ ml at the seventh day, the inhibition ability was (42.5, 50.6 and 64.4)% of the fungus F. oxysporum, respectively. And was (23.6, 42.7 and 55.1)% of the fungus A. niger, respectively. Whereas when the hydro extraction was used by the same concentrations, the inhibition ability was (59.2, 65.3 and 70)% respectively for the fungus F. oxysporum, and (46.1, 58 and 61)% for the fungus A. niger, respectively. The oily extraction showed high inhibition ability, where the inhibition rate was 100% when the extraction was used by the two concentrations 50 and 75 μl for both two studied fungi.
The compatibility between the varieties and the percentage of budding success and the vigor and vegetative growth of these varieties were studied. The plants growth was monitored and all the required readings were taken from the beginning of buddi ng at the end of summer until the end of the next growth season.
The research was conducted in order to test the effect of each of the filtrate T. viride and chitosan and sodium benzoate in filamentous growth pathogenic fungi F. oxysporum and F. solani, and their impact in protecting the seeds of peppers from t hese two fungi, and then assess the effectiveness of peroxidase enzyme in pepper plants from seeds treated with the above-mentioned compounds.
The purpose of this present research isto evaluate two types of mucilage from two types of jujubefruits: Z.jujube and z. Lotus, and to analyze the physicochemical and functional properties of this mucilage. The extraction process for both types we re performed under the same conditions of temperature, mixing ratio and proportion of the solvent used in the deposition process. The yield of mucilage were extracted from Z .jujube is being 5.8 g mucilage/100g dry weight, while the yield of Z. lotus is being to 25.23 g mucilage/100g dry weight The values of pH, Refractive index, Hausnerindex, Compressibility index and Swelling index for Z. jujube mucilage were: (6.32, 1.3348, 1.048, 4.68, 4.28) respectively .While those values for Z. lotus mucilage were: (6.32, 1.3360, 1.162, 13.41, 5.42) respectively. The specific gravity value for 1%solutionof Z. jujube mucilage were 1.0021 g/cm3while for Z. lotus mucilage: 1.0025g/cm3. The values of theBulk density and Tap density for mucilage powder for Z. jujube ( 0.41- 0.43)g/cm3respectively, and for Z. lotus( 0.43- 0.50)g/cm3respectively. As for the functional characteristics of thestudied mucilage, the values of water holding capacity, viscosityand oil holding capacity were: 14.6g water/g dry mucilage, 1.19 centipoise, 2.52g oil/g dry mucilage and emulsification capacity 50% for Z. jujube. While it was higher in the Z .lotus mucilage 34g water/g dry mucilage,1.23 centipoise,3.22 g oil/g dry mucilage and emulsification capacity 51.6% . These results indicate that the mucilage extracted from both mentioned types of jujube can be used as stabilizer in the field of food industry.
Young sun flower plants were exposed to ultraviolet radiation of the type UV-B (295 nm) for 3 days (2 hours per day) with or without excluding the UV-radiations using polyethylene layers (blue and transparent) (0.5 mm thick). The amount of photosyn thesis pigments was measured whereby a variation in the chlorophyll contents. Chlorophyll a (chl.a) was noticed at these rates (without covering 19.59%, transparent polyethylene 3.40%, blue polyethylene 1.66%), chlorophyll b (chl.b) at rates (7.81, 25.13, 22.79%) and the total chlorophyll content (2.88, 21.76, 20.53%), while the amount of carotenoid pigments has increased in the studied samples (24.45, 19.23, 17.32%). A decrease in the rate of photosynthetic electron transport has also been noticed (88.04, 78.71, 58.81%) in the plant samples exposed to ultraviolet radiation (on the third day) without UV excluding and with transparent and blue polyethylene successively. All results were compared to the sample which was not exposed to radiation. All results indicate the negative effect of ultraviolet radiation on the chlorophyll content and the rate of photosynthetic electron transport, therefore, on photosynthesis and the productivity of sun flower plants. They also point out the importance of carotenoid pigments in protecting chlorophyll pigments from the negative effects of this radiation. Results showed the clear positive effect of polyethylene layers, specifically the blue one, in protecting plants against this radiation.
