In this research, the occurrence of Glycaspis brimblecombei Moore (Hemiptera:
Psylloidea: Aphalaridae) was recorded for the first time on Eucalyptus camaldulensis
(Myrtaceae) leaves in Syria. Where collected from the leaves and shoots of young and
old
trees of eucalyptus from Lattakia province in June 2015 in three sites. The morphological
characters examined and compared with the specialized keys for this species. The results
showed that the highest average for psyllid egg masses was in Bustan AlBasha on the
lower surface of the leaves and amounted to 5.80±2.00 mass, had the highest average
number of eggs in the same location and on the lower surface also reached 65.80±47.97
eggs / Leaf. The highest average number of nymphs under the Lerp in Bustan AlBasha on
the lower surface of the leaves as stage as follows: L1: 18.4±9.51, and L2: 9.60±3.32, and
L3: 6.40±0.92, while L4: 2.80±1.74 on the upper and lower surfaces. The highest average
number of psyllid nymphs without white Lerp was for the first nymph L1: In Shahd
Alaasal site on the Lower surface 3.40±0.87, and L2: at the same previous location on the
upper surface of 5.80±2.43, and L3: in Bustan AlBasha site on the Lower surface
2.80±0.58, and L4: in Shahd Alaasal and Bustan AlBasha 0.20±0.20 on the upper and
lower surface. The highest average number of adult in the site Bustan AlBasha on the
upper surface of 1.40±1.16, and the lowest in the site Shahd Alaasal on the upper surface
of 0.20±0.20.
The samples of Crustaceans (Malacostraca) were collected in the fresh water, from
different regions of Al-Assi valley (the river, Katenah lake, the reservoirs such as Al-
Zaafaranh, Al-Sindianh and from Al-teen spring), between August 2010 and Augu
st 2011.
The samples were preserved in alcohol (70 %). After accurate inspection of the collected
samples, there were 4 species classified, two species of freshwater belonging to true crabs
were recognized by depending on the masculine organs as following: Potamon potamois
and Potamon setiger from the Potamidae family, one species of shrimps Atyaephyrra
dessmarestii-orintalis from Atyidae family, and only one species of amphipods which was
Grammars lacustris of Gammaridae family.
All examined species were described morphologically, explaining the most important
classified features that distinguish these species presented with clarifying paintings and
with the pictures for these features.
This study aimed to investigate the possibility of rapid identification of
isolated bacteria Leuconostoc from Syrian white fresh cheese made of cow and
ewe milk using Fourier transform infrared spectroscopy (FTIR). 20 isolates (14
from ewe milk ch
eese and 6 from cow milk cheese) were isolated. These isolates
were pretasted with PCR technique using specific primers. Results indicated
that these isolates are belonged to the genus Leuconostoc and 12 of them are
belonged to Ln. mesenteroides species. The results of FTIR technique showed in
comparison to device library that all isolates are belonged to genus
Leuconostoc, and 4 of these isolates are belonged to Ln. citreum species which
could not be identified using PCR method (with the used primers), and helped
to identify the following subspecies: Ln.mesenteroides subsp mesenteroides and
Ln. mesenteroides subsp dextranicum while PCR technique described them
belonging only to a Ln. mesenteroides species. Moreover, FTIR technique was
able to give the results within 25 hours, thus it can be used in identification of
food bacteria more quickly.
This research concludes an determination of some Culicinae mosquitoes
distributed in south of Syria.
The study show that there are 14 species, 3 of them were recorded for the
first time in the study area, these 3 species were described, illustrate
d , and
distinguished from related species ,the seasonal reproduction and the habitat
types of these were studied .
(Culex perexiguus , Cx.sinaiticus , Cx.territans).
للفطريات الممكرزة أهمية تطبيقية كبيرة و بخاصة فيما يتعلق بتحسين تغذية النباتات المضيفة
بالعناصر المعدنية و زيادة مقاومتها للظروف البيئية المتطرفة من برودة و جفاف و ملوحة تربة، و مقاومتها للعوامل الممرضة.
تعد مثل هذه الدراسات عن التعايش نادرة في سور
ية، لذلك فقد حاولنا دراسة هذا النوع من التعايش
لدى بعض النباتات الاقتصادية في مناطق مختلفة في سورية ، و حاولنا تحديد الجنس أو النوع الفطري
المسؤول في كل حالة، و ركزنا على بعض نباتات الفصيلتين السرمقية و الملفوفية، بعد أن أشار بعض
الباحثين إلى عدم قدرة نباتات هاتين الفصيلتين على تشكيل فطريات جذرية.
This research was conducted at the Department of Food Science,

أقترح ضمن هذا البحث مقارنة كل من طريقتي التصنيف المباشر و التصنيف غير المباشر و ذلك من خلال دراسة مقارنة كل من خوارزميتي RIPPER و الجار الأقرب, بهدف تحديد ما يناسب كل حالة من حالات المستخدمين المتغيرة مع الزمن.
In this study, 200 Tittigoniids specimens were collected from 32 locations in Syrian
coast during 2012 and 2013 seasons. Morphological and taxonomical aspects of
collected specimens have been studied. Identification keys of families, genera,
and s
pecies were recorded according to the most important taxonomic features.
A total of eighth genera recorded and classified, and these were: Phaneroptera
nana, Phaneroptera sparsa, Acrometopa syriaca, Tylopsis lilifolia, Conocephalus
conocephalus, Conocephalus maculatus, Conocephalus concolor. The species
Isopya savigny was considered the first record in Syria.
