This study was done to find ways that decrease the negativity of chemical pesticides which they are used for pests control . For that ,a lot of laboratory tests were done ,in Faculty of Agriculture, Tishreen University, to estimate the efficacy of six extracts of wild plant fruits in controlling the T.urticae communitie, Because these extracts are natural products that they are dissolve biologically, and they are more safety and specialty. Results of new eggs treatment showed that the effect of extracts of Melia azedarach, E. camaldulensis, L. camara , S.aspira, S.officinalis and C. sempervirens fruits lasted between 21.31 -22.95%, and exceeded 36 and 42% for S. aspira and S. officinalis respectively. The greatest effect (100%) happened after 3 days of new larve treatment with fruit extract of M.azedarach, 5 days for S. officinalis and S. aspira , and 7 days for L. camara . S.officinalis, L.camara and S.aspera extracts are showed the total effect (100%) after 5-7 days of adult female treatment, While the efficacy of M.azedarach and E.camaldulensis extracts lasted about 90% . The less effect, although good, was achieved by C.sempervirens extract. The number of eggs placed by new females decreased about 90% with M.azedarach and S.officinalis extracts , and 83% with , L.camara extract. The placed eggs ratio with all extracts didn’t exceed 42.29% which happened with C .sempervirens extract. Significant differences between all treatment and control were found and although with the three growth phases of T.urticae which tested in this study

Mortadella was processed from second beef meat was prepared by adding soybean meal(whole fat, skimmed) at different rates of 11, 13, 15, 17, 19 and 21%. The change in the chemical composition (moisture, protein, fat, chloride Sodium, ash, acidity, pH, peroxide), as well as changes in sensory properties (taste, color, texture, odor, appearance), microbial properties (general census of aerobic bacteria, yeasts and molds, E. coli, salmonella). The results of the chemical analysis showed that the moisture of the mardadella increases with the percentage of added soy meal to become outside the standard in the proportion of soya 21%. As for the ash, the ash content is high with the percentage of added soy flour, but it remains below the 3.2% specified in the specification. For the protein, all the samples with the control within the standard (12% minimum) with the high percentage of protein by adding soy flour, and for the salt, its percentage in all samples is in accordance with the specification ( 2% maximum), as for Peroxide values showed a decrease in the proportion of soy flour. Sensory tests showed that all sensory properties improved by adding soybean meal in all mixtures, except for mixtures, where the proportion of soy meal 21%. The microbial tests showed that there were no pathogens, especially Salmonella and E. coli, and showed that the total population of air bacteria, yeasts and breakfast was within the limits of the Syrian standard. There was a decrease in the general bacterial count for the samples added to soybean meal compared with the witness , And there is a convergence of the general number of yeast and breakfast for the samples added to soy flour, which is within the natural area. The results also showed an increase in the profitability of the mortadella. This increase was achieved by increasing the added meal to 115.81 and 110.76% in the samples of mortadella with low fat and whole fat soya meal at 21%, respectively

The experiment was done to investigate the germination of seeds and embryos of Olea europaea “Alkhdery” in the Germination Laboratory- Faculty of Agriculture- Tishreen University during 2016-2017. The Study consisted of multiple experiments ,each of which consisted of many treatments . Every treatment had 3 replicates , where one had 10 seeds/embryos . The planting was performed on Agar medium 0.8%. The results showed that the ideal temperature for the germination of olive seeds was 13 c°. However , the rhythm of germination decreased when the temperature went beyond or below 13c° and stopped at 5c° and 25 c°. The ideal temperature for the germination of embryos was 13c° . However , many embryos germinate early at 20 or 25 c° with sharp decrease in the germination level . As for kernels the results showed that they couldn’t germinate at 13 c° due to their hard coats which stopped the entrance of water and oxygen. Also , the germination of seeds lagged behind that of the embryos due to the Endosperm coat which covered the embryos and stopped the passage of water and oxygen .In addition to that, it contained materials that crippled the germination process

Alien species represent an important part of the crustaceans of Syrian fowl, which are about 128 species. The total number of migratory species in Syrian waters recorded in this work make up only 27 species. This number represents 21.5% of all marine Decapoda known in Syria and 38.8% of introduced species in the Mediterranean. Decapoda species introduced into Syria belong to 10 different families and are spread over 22 genera. The family Penaeidae and the family Portunidae are the most represented in introduced species with 7 for each. The Leucosiidae family ranks second by the number of species with 4 lessepsian and then the Pasiphaeidae and Alpheidae families represented by two species. Only one introduced species has been reported for the following families: Palinuridae, Majidae, Matutidae, Xantidae and Pilumnidae. Of the 27 species decapod found in Syria, 5 have been reported for the first time in the marine waters of this country during the last decade and two among this, registered in 2017 for the first time. These species are Melicertus hathor, Alpheus audouini, Arcania elongata, Matuta victor and Gonioinfradens paucidentatus. It is accepted that alien species may have ecological, economic or health related influences, especially after they succeed in establishing dense population, or presenting invasive characters. The invasion of exotic species on the Syrian coast by the Suez Canal plays also a big role in modifying the original specific composition of Syrian waters.

This research was carried out during the agricultural season 2014-2015 in the village of Asayba ,Banias region in Tartous province. According to the design of the complete random sectors, three replicates and the objective of the study the effect of seed rates on the productivity of barley varieties: improved white Arabic, Furat-2. In the study, four agricultural distances (1- 1.5-2 cm) were used for barley cultivars that are compatible with seed rates of 160-110-80-115 kg / h, respectively. The results of the study showed that the seed yield was 160 kg / h, which was significantly higher in yield and number of grains / spike than the rest of the seeds. In both cultivars, the yield was higher than 1000 g / 1000 tablets and the number of non-fruitful activities / m 2. The interaction was significant "between the white Arab variety and seed rate 160 kg / e, where it gave the highest productivity in the yield of biological and granular.

This study aimed to investigate the Endoparasites in Sparus aurata in the Lattakia marine waters. A total of 54 individuals of Sparus aurata were collected between October 2015 and September 2016 from different localities from the coast of Lattakia between Ras Al Baseet and Iben Hani. Internal organs (stomach, intestines and body cavities) for all individuals caught fish were examined for parasitic infection. We isolated the parasite Hysterothylacium aduncum that belongs to the Nematodes from the stomach and intestines of Sparus aurata. The results showed that the highest rate of infection with this isolated parasite was in the summer, which amounted to 25% and has coincided with high temperature. During this research, the parasite was isolated for the first time from Sparus aurata, which caught in the Syrian marine waters.

The study aimed to determine the effect of sodium chloride (NaCl) solution on the germination of the seeds of some citrus rootstocks. In this study, the seeds of rootstocks used: Citromelo, Carizo citrang, Troyer citrang, Trifoliate orange, Cleopatra mandarin, and Sour Orange. The experiment was designed in a Randomized Complete Block Design, and included four treatments, each with 5 replicates and each 20-seed repeater. The results analyzed by using SPSS and ANOVA to determine the Significant Differences between treatments and rootstocks studied. After analyzing the observed data for treatments and rootstocks, the study showed that there is no reciprocal effects between the studied rootstocks and the saline treatments, increased saline concentration according to the treatments reduces the percentage of germination at the level of the single rootstock. However, at the level of all rootstocks, there are no significant differences at the effect of the treatments in rootstocks seed germination, where the rootstocks are similar in the rate of decrease in germination depending on the salinity treatments, there is a convergence in the percentages of seed germination in the first treatment (control) and the second treatment (1000 ppm). Then we note that the percentage of germination in the third and fourth treatments (2000, 3000 ppm) is reduced, With the exception of Citromelo rootstock seeds whose percentage of germination was not affected by an increase in saline concentrations, as well as the Troyer citrang rootstock, whose seed germination was only slightly affected in the fourth treatment. As for the effect of sodium chloride solution on the continuation of seedling growth, it is noted that the highest percentage of seedling death was Cleopatra mandarin rootstock, It reached 69.31% in the fourth treatment (3000ppm), whereas the seed of Citromelo rootstock tolerance Salinity, and the percentage of death Seedling only 22% in the fourth treatment
