A laboratory study was conducted on the parasitoid Citrostichus phyllocnistoides Narayanan (Eulophidae : Hymenoptera)under average of temperature (18.12± 2.12 Cº) with Temperature range from 15-23Cº. The final results oflaboratory study indicated that parasitoid was passed four stages to complete life cycle. The average development time was: 3.7±0.9 days for eggs – 7.8±0.9 days for larvae,(the time required from the eggs to hatch and continued untilthelarvae enter the pupal stage 6-10 days) , and12.7±1.03 days for pupa (the time required from the beginning of pupation to emergence of adult 11-14 days). The parasitoid needs in average23.3±2.7 days to complete its life cycle. Male longevity 3.8±0.8 days , and female 4.2±0.9 days.

Research summary
أجريت دراسة مخبرية على المتطفل Citrostichus phyllocnistoides Narayanan (Eulophidae: Hymenoptera) تحت درجة حرارة متوسطة 18.12±2.12 مْ، وبمجال حراري من 15-23 مْ. أظهرت النتائج أن المتطفل يمر بأربع مراحل لإكمال دورة حياته: بيضة - يرقة - عذراء - بالغة. بلغ متوسط زمن تطور البيض 3.7±0.9 يوماً، ومتوسط عمر اليرقات 7.8±0.9 يوماً، ومدة طور العذراء 12.7±1.03 يوماً. يحتاج المتطفل في المتوسط 23.3±2.7 يوماً لإكمال دورة حياته. بلغ متوسط عمر الذكور 3.8±0.8 يوماً، والإناث 4.2±0.9 يوماً. تهدف الدراسة إلى دراسة دورة حياة المتطفل ضمن ظروف المختبر لتحديد إمكانية إكثاره وإطلاقه في الوقت المناسب للسيطرة على الآفة في بساتين الحمضيات في الساحل السوري.
Critical review
دراسة نقدية: الدراسة تقدم معلومات قيمة حول دورة حياة المتطفل Citrostichus phyllocnistoides وتساهم في فهم كيفية استخدامه كعامل بيولوجي لمكافحة حافرة أنفاق أوراق الحمضيات. ومع ذلك، يمكن تحسين الدراسة من خلال تضمين تجارب ميدانية لتأكيد النتائج المخبرية والتحقق من فعالية المتطفل في الظروف الطبيعية. كما أن الدراسة تفتقر إلى تحليل اقتصادي لتقدير تكلفة وفوائد استخدام هذا المتطفل مقارنة بالطرق التقليدية لمكافحة الآفات.

This study has been done on Sparus aurata (Sparidae). Fish samples (297 individuals) were collected along the Syrian Coast from March 2012 to February 2014. Total length (T) was 15 - 31 cm, and the total weight (W) was 53,1 - 410,34 g. The study o f gonado somatic index (GSI) showed that the reproduction period was between November and February with a maturity peak in January (3.98±0.97)% for females ,and in December (2.19±0.29)% for males. In addition, the length at the first sexual maturity was (21.5 cm) and (22.5 cm) for males and females respectively. The results of the hepato somatic index (HSI) was compatible with the surrounding environmental and physiological changes which resulted from the change of sexual activity during the reproductive cycle. Fecundity showed a wide range for a given length, there was a linear relationship between the absolute fecundity and each of length groups and total weight. Relative fecundity was (567896-849362) egg per 1kg body weight. The frequency distribution of eggs diameters revealed the presence of one peak, and the eggs diameter during the reproduction period ranged from 0.05 to 0.3mm.
A Laboratory study was conducted during 2010 on the biology of seed beetles: Callosobruchus chinensis, C. maculatus and C. analis (Coleoptera: Bruchidae) on lentil seeds for the first specie and chickpea seeds for the last two species. These beetles completed 10, 8 and 5 generations respectively when they were active (from March to November for the first and second species and from April to October for the third species ). C. maculatus laid an average of 100.29 ± 18.26 eggs over a period of 11.14 ± 0.64 days, C. chinensis laid 83.29 ± 6.32 eggs over 6.43 ± 0.49 days and C. analis 75.29 ± 9.05 eggs over 6.71 ± 0.70 days. The total development process from egg to adult takes an average of 25.87 ± 3.29, 31.43 ± 5.09 and 35.36 ± 3.49 days respectively for species under the ambient laboratory conditions. There was no difference in the development time between males and females except for C. maculatus, where the male emerged about twelve hours before the female. Sex ratio (male: female) was more in favour of female than male in C. chinensis (1: 1.1) and more in favour of male than female in C. maculatus (1.1: 1), but equal in C. analis (1: 1). The parasite wasp Anisopteromalus calandrae (Howard, 1881) (Hymenoptera: Pteromalidae) could be considered the first recorded on C. maculatus in Syria.
The research aims to determine the levels of Tishreen University students' on the "satisfaction with courses" scale, and to find out if there are differences between Tishreen University students in the "satisfaction with courses" scale, according t o the variables: (gender, academic specialization). A total of (749) undergraduate from Tishreen University students in all faculties, participated in this research, using the "satisfaction with courses" scale. Search results are summarized as follows: The average scores obtained by all faculties for their students' satisfaction with the courses were within the level of satisfaction (average), and there were a differences among the members of the research sample in the scale according to the "gender" variable in favor of females, and there were a differences according to the "academic specialization" variable in favor of the theoretical academic specialization.
The research aims to examine the relationship between organizational culture on the one hand, and between knowledge management practices in Tishreen University, on the other hand, where the researcher distributed a questionnaire to a sample of the colleges in the University of Tishreen reached (205) questionnaire was recovered (222) to identify them, it was good of them use (158) questionnaire. To test the relationship, the researcher used the Student T test for one sample, as well as the Pearson correlation coefficient.
