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.
