They are: Schizaphis graminum (Rondani), Rhopalosiphum padi (L), Rhopalosiphum maidis (Fitch) and Sitobion avenae (Fab). S. graminum was most widely amounted rate (48%), followed by specie of R. padi (% 20) then R. maidis (% 16.8), and finally specie of S. avenae rate (14.9%).

Research summary
تتناول هذه الدراسة ديناميكية المجتمع الحشري لحشرات المَنّ التي تصيب نباتات القمح في محافظة درعا، جنوب سوريا. تم تحديد أربعة أنواع من حشرات المَنّ التي تنتشر في حقول القمح وهي: Schizaphis graminum، Rhopalosiphum padi، Rhopalosiphum maidis، و Sitobion avenae. كان النوع S. graminum الأكثر انتشاراً بنسبة 48%، يليه R. padi بنسبة 20%، ثم S. avenae بنسبة 16.8%، وأخيراً R. maidis بنسبة 14.9%. تم تحديد مواعيد ظهور الأطوار المختلفة لهذه الأنواع (الحوريات، الحشرات غير المجنحة، والحشرات المجنحة) وتاريخ وصول الذروة لكل نوع. أظهرت النتائج أن حشرات المَنّ تبدأ بالظهور على نباتات القمح في الأسبوع الثالث من كانون الثاني، وتزداد أعدادها حتى نهاية شباط، ثم تصل إلى الذروة في نهاية آذار. تتركز الإصابة بحشرات المَنّ على الأوراق والحبوب، وتظهر الحشرات المجنحة عندما تقل جودة العائل أو بسبب الازدحام أو ارتفاع درجة الحرارة. توصي الدراسة بالتبكير بالزراعة والتخلص من النباتات والأعشاب الضارة المحيطة بالحقول، ودراسة الأعداء الحيوية لحشرات المَنّ واختبار بعض المبيدات لمكافحة هذه الآفة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في فهم ديناميكية المجتمع الحشري لحشرات المَنّ وتأثيرها على نباتات القمح في منطقة درعا. ومع ذلك، يمكن تحسين الدراسة من خلال توسيع نطاق البحث ليشمل مناطق أخرى في سوريا، مما يساعد في الحصول على صورة أشمل عن انتشار هذه الحشرات. كما يمكن تعزيز الدراسة بإجراء تجارب ميدانية إضافية لاختبار فعالية المبيدات المقترحة وتحديد أفضل الطرق لمكافحة هذه الآفة. بالإضافة إلى ذلك، يمكن أن تكون الدراسة أكثر شمولية إذا تناولت تأثير التغيرات المناخية على ديناميكية حشرات المَنّ بشكل أعمق.

Monthly population fluctuations of plant parasitic nematode population
associated with root of cotton in central province fields in Syria were studied
over a 2-year period 2008-2009. In both years, the differences between monthly
samples were not
significant. Average of nematode population density in soil
decreased after sowing (May) and near the end of the season (at harvest) in
both years and in all of the central province fields, then the numbers of
nematode increased slowly again in June to reach a peak at mid-season (July).
Ghab region had the higher population density (1180.8 juveniles/100cm3 soil).
An increase in numbers of nematode in soil was accompanied with a decrease
in number in roots. Negative correlation was observed between average of the
initial population density and reproduction factor. Pratylenchus, Meloidogyne
incognita, Rotylenchulus, Tylenchorhynchus were dominant nematode species
in these fields. Also, the infestation of the first three nematode species was not
uniform.
Family Vespidae considered as Widespread globally and belong to the order
Hymenoptera called wasps, It contains about 5000 species belong to six subfamilies.
Members of this family differ in terms of style of living and life cycle and the type of
diet. Colors overlap between the black and yellow or red, yellow or three together.
This study examined six species belong to the four genera (Vespa, Vespula, Poistes,
Delta) and three sub-families are: Sub.Fam. Vespinae, Sub.Fam. Polistinae, Sub.Fam.
Eumeninae, gathered from many different areas of the province of Latakia
environment (15 area) from altitudes ranging from sea level to a height of 1000
meters, over a period of time it extends from April through October of 2015.
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.
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%).
A survey to record the genera of nematode associated with wheat in the
south region of Syria was carried out during 2002/01. 600 soil samples were
collected from the rhizosphere of wheat and examined. Nematodes were
extracted, identified and frequ
ency was calculated for each genus. Results
showed that 17 genera of nematode were associated with wheat. These genera
were divided into three groups. The free living nematode consisted of eight
genus, the plant and fungi nematode three genus and the plant parasitic
nematode group contains six genus.
