Ash toxicity of burning pruning residues of three plant species i.e. apple, grape and olive was tested against adults of cowpea seed beetle Callosobruchus maculatus (F.) (Coleoptera, Bruchidae) using the following concentrations: (5, 10, 20, 40 and 80) g/kg of cowpea seed. The study was carried out in incubator at fixed temperature and humidity at Biotechnology Research Center, Al-baath University. Readings were taken after (24, 48 and 72) h of treatment, and corrected mortality rates were calculated and values of LC50, LC90, LT50 and LT90.

Research summary
تتناول هذه الدراسة سمية رماد نواتج تقليم أشجار التفاح والعنب والزيتون ضد خنفساء اللوبياء العادية Callosobruchus maculatus (F.) تحت الظروف المخبرية. تم اختبار خمسة تراكيز مختلفة من الرماد (5، 10، 20، 40، و80 غرام/كغ من بذور اللوبياء) وتمت متابعة النتائج بعد 24، 48، و72 ساعة من المعاملة. أظهرت النتائج أن رماد التفاح كان الأكثر سمية وأقل زمن للقتل مقارنة برماد العنب والزيتون. تم حساب نسب القتل المصححة وقيم LC50 وLC90 وLT50 وLT90 لكل نوع من الرماد. أظهرت النتائج أن زيادة التركيز وزمن التعرض يزيد من نسبة القتل المصححة. خلصت الدراسة إلى أن الرماد يمكن أن يكون بديلاً فعالاً وآمناً للمبيدات التقليدية في مكافحة خنفساء اللوبياء العادية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة في البحث عن بدائل آمنة للمبيدات الكيميائية التقليدية، ولكن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل إجراء تجارب ميدانية بالإضافة إلى التجارب المخبرية للتحقق من فعالية الرماد في الظروف الحقيقية. ثانياً، لم يتم التطرق إلى تأثير الرماد على البيئة المحيطة أو الكائنات غير المستهدفة، وهو جانب مهم يجب مراعاته في الدراسات المستقبلية. أخيراً، كان من الممكن توسيع نطاق الدراسة ليشمل أنواعاً أخرى من الحشرات الضارة للتحقق من فعالية الرماد بشكل أوسع.

The bio-effect of anise oil and its fruit extracts(alcoholic and aqueous extract) to control the cowpea beetle, Callosobruchus maculatus that infest stored leguminous crops was investigated. The study was conducted according to three treatments: e vaporation, direct spray of insects and food spray. The anise oil was used at different concentrations from 0.05 to 5%. Whereas, the aqueous and .alcoholic fruit extracts were used as 30%.
This experiment was carried out to study the effect of increasing gamma radiation doses (up to 24 GY) on the eggs of Callosobruchus maculatus, at different ages, to determine their effect on egg hatching rate, and other biological traits of the em erging adults from eggs treated with sub – lethal doses. It has been noticed that the low gamma radiation doses killed most of the one –day old eggs before hatching, and no adult insect could emerge from hatching those eggs, and the dose of 12GY caused the same effect, but on two day-old eggs. when eggs were at the age of 3, 4, and 5 days, gamma radiation didn’t have influenced on the embryo development, but demise percentage, increased after hatching. The percentage of emerged adults was only 1.8% for the eggs treated with 16 GY gamma radiation.
This investigation was carried out in the fields and laboratories of Pome and Grapevine Department, GCSAR/Syria, on some apple varieties i.e. Richared, Mutsu and Tourly Winsap to determine the optimal harvest date and its effect on storability. Fr uits were harvested in (16/9, 26/9, 7/10, 17/10 and 30/10) depending on physical and chemical maturity indicators, and stored with the study of changing in quality indicators and weight lost monthly. The results showed that the studied varieties differed in their storability according to harvest date, Richared fruits in 26/9 showed long storage for seven months with weight loss of 4.9%, fruit firmness 6.4 kg/cm2, and 18.7% TSS. While the storability was six months for Mutsu fruits which harvested in 7/10 with weight loss of 4.4%, and fruit firmness 6.1 kg/cm2, and finally, Tourly Winsap fruits which were stored for five months in 7 and 17/10 harvest dates with fruit firmness 5.1 kg/cm2. Moreover, the three varieties were able to storage for three months when harvested in 30/10 with weight loss of 3.3%, 4.4% and 4.5% in Tourly Winsap, Richared and Mutsu respectively, which considered as consuming maturity for these varieties. These results indicated to the various storage periods according to fruits harvest time, and the storability, which assists in regulating offer and demand, and providing markets with fruits for long period, however harvesting at optimal time reducing the total weight loss, in addition to high quality indicators.
A field experiment was conducted on sandy loam soil under the irrigation conditions in Deir- ezzor during the years of ١٩٩٨ and ١٩٩٩ to study effect of planting time and seed rate on growth and productivity of tow varieties of rape crop Brasica napous var. oleifera (Bromin & VEM).
Records of ٤٤٥ Friesian cows were analysed for calving interval and its components; days open, lactation length and length of dry period. The model included parity, calving year and calving season. The overall means were ٤٢٥,٧٧ ± ١,٨٩, ١٤١,٣ ± ١,٣ ٧, ٣٥٣,٩ ± ٠,٨٨ and ٧٣,٠٢ ± ٠,٧٧ days for calving interval, days open, lactation length and length of the dry period respectively. These estimates are high by tropical and subtopical standards, but they remain lower than the reproductive performance of Friesian cattle in temperate countries.
