Research summary
تقدم هذه الدراسة مسحًا أوليًا لأنواع الذباب الزهري (Syrphidae) في بعض الحقول في منطقتي جيلين وإزرع بمحافظة درعا. تم تنفيذ الدراسة الميدانية خلال الفترة من 1 مارس 2003 حتى 30 أغسطس 2003. تم تحديد ووصف الأنواع التالية: Episyrphus balteatus، Melanostoma millinum، M.scalare، Metasyrphus corollae، Metasyrphus latifasicatus، Syrphus ribesii، Chrysotoxum intermedium، Scaeva albomaculatus، Scaeva pyrastri، Sphaerophorea scripta، Eristalis arbustorum، وEristalis taeniops. تم تصنيف هذه الأنواع وفقًا لمفاتيح التصنيف العالمية. تعتبر عشرة من هذه الأنواع مفترسات طبيعية هامة لمكافحة حشرات المن وتستخدم في برامج الإدارة المتكاملة للآفات (IPM). بينما تتغذى يرقات نوعين آخرين على المواد العضوية المتحللة.
Critical review
دراسة نقدية: تقدم هذه الدراسة مساهمة هامة في فهم تنوع وانتشار أنواع الذباب الزهري في منطقة درعا، وتبرز أهمية هذه الأنواع في مكافحة الآفات الزراعية. ومع ذلك، يمكن تحسين الدراسة من خلال تضمين مزيد من التفاصيل حول منهجية جمع العينات وتحليل البيانات. كما أن الدراسة تفتقر إلى مناقشة تأثير العوامل البيئية المختلفة على توزيع الأنواع. سيكون من المفيد أيضًا مقارنة النتائج مع دراسات مماثلة في مناطق أخرى لتعزيز الفهم الشامل لتوزيع هذه الأنواع.

This study was conducted during the period from 10/9/2016 to 9/9/2017 in Demsarkho orchards area (Lattakia) on the west coast of Syrian Arab Republic. The study aimed to identificate "Syrphidae" in this area. Samples were collected by yellow dishes in weekly rate. A total of 341 Syrphid flies were collected and they belong to 15 species form 10 genera. The most abundant species was Sphaerophoria scripta (relative abundance 33.43%), followed by Episyrphus balteatus (20.53%), then Melanostoma mellinum (14.66%).
This research was conducted at two distinct environmentally locations, Jellien and Al-Somakiate belong to Dara'a Research Center, the General Commission for Scientific Agricultural Research during 2011-2012 growing season. 13 garden pea genotypes were planted according to a randomized complete block design with three replicates to study the performance of these genotypes for 10 important quantitative traits and to detrmine the genotypic and phenotypic coefficients of correlation between the traits studied. Results showed that there were significant differences among the genotypes for all traits studied at both distict locations. The genotypic correlation coefficients were higher than corresponding phenotypic correlations, in addition, the value and direction of correlation coefficient at both levels were different from location to another. Green pod yield showed positive and significant correlations with pod width, harvest index and 10-green pod weight at Jellien location, and with pod length, pod width, pods number per plant and 10-green pod weight at Al-Somakiate location.
Inhabitants' increase in the governorate of Daraa has great effect on civil development, as it is the case in other governorates of Syria, this is quite evident in the increase of inhabitants in civil centers, and its horizontal extension continuo usly. Due to the importance of this subject, I studied it, where the research included a survey of its problem that the continuous inhabitants' increase has been the cause of the increase of the number and volume of civil centers during the period between 1970-2010, where the rate of civilization increased by 14.3% to 41.6% The number of inhabitants in the governorate is expected to reach (1.631.005) inhabitants in the year 2025. that's with an increase of 505.005 inhabitants. The research included its importance, objective and courses, the developed number of inhabitants in the governorate, and effective factors that affect it, with the increasing number of civil centers. In addition to studying indications of civil development such as education, health, culture, services, industry, housing, then discussed their problems and impediments, such as the increasing rates of inhabitants, the random housing, environmental pollution, then presenting future suggestions and solutions for them.
A survey to record the genera of nematodes associated with chickpea of domestic variety, which are planting at Izra’a Research center in Dara’a Governorate, was carried out during the period from April 2003 till June 2003. Nematodes were extracted , examined and identified to genus. Population density, frequency (%), and prominence value (PV) were calculated for each genus of 40 samples were collected from the root rhizosphere soil and from plant roots itself. Results showed that eight genera of plant-parasitic nematodes, and seventeen genera of other nematode groups were associated with chikpea plants.
The study was carried out at Soil Research Center in the province of Daraa during 2011 in order to study some physical and moisture characteristics for cinnamon soil, which occupies (48000 km²), equivalent to 26% of the area of the Syrian Arab Rep ublic and represents the cultivation of growing field crops with a rainfall ranges between 150- 300 mm. The results showed that the mechanical analysis for soil referred that its texture is clay with a good ability to retain water, the field capacity rated between (30-38.85)%. The studied soil has high value of available water (38.93mm) and useful water (25.69mm) in the surface layer. The highest value of permanent wilting point and hygroscopic moisture was reached in the final depth in studied profile soil, It was also distinguished a high total porosity ranged between 51.78 and 55.59% with a good air porosity amounted to 9.38 - 15.47 % in different depths and with the decline to 5.51 % in the depth 30 - 45cm.
