أظهرت النتائج أن زراعة كلا من الصنفين المختبرين (12167, NN25)الحساسين للإصابة بدبور الحنطة المنشاري الأوربي Cephus pygmaeus بجانب أحد أصناف القمح المزروعة (ICPW 13172) قد أدى إلى تخفيض نسبة إصابتو بهذه الحشرة بمقدار18.2-7.2% عندما أجريت التجربة ضمن أقفاص و 9.5 -6.2% في الظروف سلبياً الحلقية في موسمي الدراسة. كما أثر الصنف 12167 على حياتية وحيوية هذه الحشرة بالمقارنة مع الصنف NN25، حيث تسبب بقتل معظم يرقاتها ضمن سوق القمح أثناء تطورىا (54.03% في موسم 2011 و 70.72% في موسم 2102)، كما خفض من خصوبة الإناث التي تابعت تطورها وانبثقت في الموسم التالي وكانت أقل بشكل معنوي من خصوبة الإناث المنبثقة من الصنف NN25. حيث كان متوسط خصوبة الإناث المنبثقة من الصنف 48.32 ،47.48 NN25 بيضة في موسمي الدراسة بينما كان متوسط خصوبة الإاث المنبثقة من الصنف 12167 في موسمي الدراسة 28.32 و28.36 بيضة.
The results showed that the use of both susceptible wheat cultivars to wheat stem sawfly Cephus pygmaeus (NN25, 12167) beside a cultivated wheat variety (ICPW 13172) reduce damage proportion by European wheat stem sawfly to cultivated variety 7.2-18.2% when the experiment was carried out within the cages and 2.6 to 5.9% in field conditions. While the variety 12167 affect negatively on the life and fitness of this insect compared with variety NN25 where it cause of killing most of the larvae within its stems (54.03% in 2011 and 70.72% in the 2012) during its development, It also reduced the fertility of females, which followed its development and emerged in the following season, it was significantly less than the fertility of female emerging of NN25. Where the average female fertility of NN25 in two seasons 47.48, 48.32 egg, while the average fertility of female of 12167 in two seasons 28.32 and 28.36 egg.

This research was conducted at the farm of Abu-Jarash, Faculty of
Agriculture, Damascus University. The aim of this research was to
evaluate the performance and productivity of 9 bread wheat (T.
.aestivum )and 3 durum wheat T. durum.
The experiment was laid out in a Random Complete Block design
(RCPD) with three replication.
Sunn bug Eurygaster integriceps selects certain weed plants to lay it’s eggs.
This study was conducted to find out the most preferable weed by this pest in
wheat fields in Northwestern Syria.
The environmental and biological study of the olive moth Prays Oleae.B was conducted in the Natural Resources Research Department of Homs Research Center in 2015-2016, where seasonal changes of the olive moth P. oleae group were monitored using pheromone sexual attraction traps.
A field experiment was conducted during the two consecutive growing seasons
(2010/2011 and 2011/2012) at Ezra’ Research Station/Deraa/Syria in order to evaluate the
role of some agricultural practices in improving the performance of four wheat vari
eties
(Acsad1105, Acsad1229, Acsad885 and Acsad901) under rainfed conditions. The experiment
was laid according to factorial randomized complete block-split design with three
replications. The mean average of early vigor, flag leaf area, peduncle length and leaf area
index was significantly higher during the first growing season for the wheat variety
(Acsad901) at the first planting date with a nitrogen amount of (150 kgN. Hectar1), and
when nitrogen fertilizers were added twice (1.6-2.5, 53.4cm2, 16.3cm, 1.20 respectively).
The mean average of the same studied aspects, however, was significantly lower during the
second growing season in the case of the variety Acsad855 with regards to the early vigor,
as well as in the case of the variety Acsad1129 in the case of the leaf area Flag at a late
planting date, and without nitrogen fertilizers (3.6 4.5, 3.3 cm, 0.18, 16.6 cm2
respectively). The mean average of the grain yield was significantly higher during the first
growing season for two wheat varieties (Acsad901, Acsad1229) at the first planting date,
nitrogen rate 200 kgN. Ha-1, and when nitrogen fertilizers were added twice (660.4, 631.1
g.m-2 respectively), while it was significantly lower during the second growing season for
the variety Acsad1105, at a late planting date, and without nitrogen fertilizers (127 g.m-2).
Optimizing some important cultural practices helps increasing wheat grain yield by
improving morpho-physiological traits related to yield particularly the size of source
photo synthise (Leaf Area Index, Flag leaf area). The response of astivum wheat variety
was better compared to durum wheat. This shows the importance of improving crop
mangment factors in order to reach the maximum potential yield.
This research was conducted at Izraa research station of The General
Commission for Scientific Agricultural Research during the growing season
2010/2011 to study the performance of six durum wheat varieties at early
growth stage under water defici
t stress. The experiment was designed using
randomized complete block design with three replication. The statistical
analysis results of the experiment clearly showed genetic variations among
cultivars under water stress. Drought stress caused a depression in all studied
traits. Mean yield decreased in average 31.7 %. The number of spiks/ m2 was
the most trait affected by drought stress, It decreased in average 29.1% while
biological yield decreased in average 24.26%. It was observed that the number
of spikes per m2 was the highest in the variety Hourani (191) and the highest
number of grain per spike (34.1) whereas the variety Bohouth7 and the variety
hourani recorded the highest thousand grain weight (40.5 g). The statistical
analysis results showed that the variety Cha5 a achieved the highest grain yield
per m2 (239.4 g), whereas, the variety Bohouth7 recorded the lowest grain yield
per m2 (182.8 g), under water deficit stress conditions.
