The impact of larvae feeding of of the agromyzid fly (Phytomyza orobanchia Kalt., and curculionid weevil (Smicronyx cyaneus Gyll.), inside shoots and seed capsules of branched broomrape (Orobanche ramosa L.) which infested tomato, in some phenologi
cal parameters: shoot length, number capsules/shoot, wet and dry weight of shoot, were determined. The results indicate to the efficacy of larvae feeding in reduction of O. ramosa bio-mass, it caused significant reduction in the values of all studied parameters, of infested branched broomrape plants in comparison to healthy ones, While the mixed infestation of the both insects caused higher reduction in the values of these parameters, with high significant differences in: shoot length, number capsules/ shoot, and wet weight of infested shoot, in comparison with healthy ones. the reduction rate which resulted from mixed infestation reached to 55.5%, 58.8%, 76.7%, 57.2% for shoot length, number capsules/ shoot, wet weight and dry weigh respectively. The results indicate to the potential role of P. orobanchia and S. cyaneus in reduction the density of O. ramosa in tomato fields, at the Syrian coastal region.
The importance of this scientific research stems from the increasing demand for
building materials, especially the materials involved in concrete industry. The attention
was directed towards finding alternative locations for primary oresin addition
to the
process of reconstructing old mines as the continues inequitable taking of these materials
will eventually result in wasting those resources losing them before using them in an
economical suitable way. We have defined the hope positions in the areas of Banias and
Tartous. We can say that deterioration of volcanic products in those areaswas a direct
result of suitable climatic circumstances which were predominant (weathering process,
deterioration, physical erosion, and chemical like wetness, wind, rain, temperature, and
surface water streaming). The tectonic which attacked those formations later served to
boost the weathering and erosion degree so that it became more effective for the
production of some oxides such as (calcium oxide, iron oxide, aluminum oxide,
deterioration of rock components, and concentration of clay) asplain strataof clay
deterioration according to geochemical analyses conducted in this research.
This study deals with the determination of the quantity of solid dust particles deposed
on the leafs of some trees along Syrian coast and the concentration of some heavy metals
in it (Zn, Fe, Pb, Cu, Ni, Cd, Co, Mn) .Some sites near to human and in
dustrials activities ,
and others near to agriculture activities , and others relatively far from pollution sources
has been selected. The results showed that the quantity of solid dust particles on leafs
trees and concentration of heavy metals in it such as (Pb, Ni, Cd, Co) increasing near the
industrials activities and dense traffic, and decreasing in the sites that relatively far from of
pollution sources. However Cypress trees attach solid quantities more than Pride of china,
following Rever red gum and Blue-leafed wattle and Oleander, and the Palm tree come in
the last.

This study has been done on Sparus aurata (Sparidae). Fish samples (297
individuals) were collected along the Syrian Coast from March 2012 to February 2014.
Total length (T) was 15 - 31 cm, and the total weight (W) was 53,1 - 410,34 g. The study
o
f gonado somatic index (GSI) showed that the reproduction period was between
November and February with a maturity peak in January (3.98±0.97)% for females ,and in
December (2.19±0.29)% for males. In addition, the length at the first sexual maturity was
(21.5 cm) and (22.5 cm) for males and females respectively. The results of the hepato
somatic index (HSI) was compatible with the surrounding environmental and physiological
changes which resulted from the change of sexual activity during the reproductive cycle.
Fecundity showed a wide range for a given length, there was a linear relationship between
the absolute fecundity and each of length groups and total weight. Relative fecundity was
(567896-849362) egg per 1kg body weight. The frequency distribution of eggs diameters
revealed the presence of one peak, and the eggs diameter during the reproduction period
ranged from 0.05 to 0.3mm.
The objective of this study is to identify some species of mycorrhizal fungi
coexisting with tomato roots in the Syrian coast. Samples were collected from five sites in
two different regions: Lattakia (sites: Siano and ALbrjan) and Tartous (sites:
Majdalon
Elbahr, Mayaar Shaker and Hrysoon). Four samples of soil and tomato roots were
collected from each site and mixed together to form a composite sample/site.
Morphological characterization of isolated fungi was based on universally adopted
taxonomic keys, and on the classification keys approved by the Plant Protection Research
Institute of Iran. Six types of mycorrhizal fungi belonging to 5 species were identified in
the different sites. Paraglomus laccaltum was present in one site (Siano), Septoglomus
constrictum was isolated from 2 sites (Mayaar Shaker and Majdalon Elbahr),
Claroideoglomus etunicatum was also isolated from 2 sites (Mayaar Shaker and Siano),
Simiglomus hoi was present in 3 sites (Siano, Majdalon Elbahr and ALbrjan), Glomus
fasciculatum was present in four sites (Siano, Mayaar Shaker, ALbrjan and Hrysoon) and
Glomus clarum was present in four sites (Hrysoon, Siano, Mayaar Shaker, and Majdalon
Elbahr).
This study aims to define bird species that use artificial lakes in Syrian coast, and
evaluate their population size for management and protection of wildlife. Four different
sites were chosen in Syrian coast, which considered the most important ar
tificial lakes.
Point counts method was used in bird survey in November, December, January, February,
March in 2011. 15 waterbird species were recorded belonging to 9 family and 6 order.
Wading birds were the main component of waterbird (60% of all species) in Syrian
coast. Populations size was 1 to 300 individuals. Diversity of birds and their Populations
were greatest in sites which are rich in food ( especially fish). The results showed a
difference in composition of bird communities in studied sites.
Ornamental plants considered one of the modern plantation, which should be
introduced in the future agricultural development plan confirmed by field studies for the
most important ornamental seed plants as a samples for data collections.
Through i
nformation and field data it can be concluded that, most of nursery's of
ornamental plants were in a small size (less than 2.5 hectare) in comparison with some
other propagated plants due to the absence of specialization. We observed a shortage in a
propagated plant materials especially cut-flowers which considered the most important
product.
This research observed also many problems facing the producers leading to high
production cost: preliminary materials, agriculture and propagation materials, expert
workers beside obstacles in exporting and absence in observation and governmental help.
During the last twenty years there was an increased interest to large extent in
crowing up the fruitful trees all over the world. That is a natural result of knowing its high
feeding value beside its being good source for income. Due to its economical importance,
there was variety of searches and studies which approached its farming.
This study was conducted in the Syrian coastal area to detect tomato seedlings
damping-off disease, to identify and isolate fungi responsible of the disease and to evaluate
their pathogenicity. Samples were collected from nurseries and greenhouses from four
locations (Jableh and Ras Elain from Lattakia and Hressoun and Majdalon Elbahr from
Tartous).
Five Species of the most widely consumed fish in the Syrian Coast (namely
Merluccius merluccius, Diplodus sargus, Siganus luridus, Lithognathus mormyrus, and
Chelon labrosus). were selected for this research. Samples were collected from the fish
m
arket in lattakia, with weight ranging between 150 and 200g. Samples were cleaned by
removing scales and inner organs, freezed at -35°C for five hours and then stored at -
18°C for a maximum period of six months.
Chemical analysis of fish samples was carried out before and after freezing periods
of one week, 1, 2, 4 and 6 months. Analysis included determination of moisture, proteins,
lipids, acidity, volatile nitrogen, and peroxide value. Organoleptic evaluation was also
performed on the control (fresh samples) and on the frozen samples after thawing and
frying. The evaluation included taste, flavor, color, texture or meat consistency and form
homogeneity.
