Contribution à l'étude de l'infestation de l'olivier par la teigne de l'olivier à travers les pièges dans la région d'Ain Temouchent
(2025) DBEBINA, ABDELILLAH; BENOUADAH, MOHAMED; Ilias, Faiza
The olive tree (Olea europaea) is a key crop in the Mediterranean basin and plays a significant role in Algeria, especially in the Aïn Témouchent region. This thesis aims to contribute to the study of olive tree infestation by the olive moth (Prays oleae) through the use of a geodatabase to map infestation hotspots and assess the effectiveness of integrated pest management methods. The adopted approach combines a bibliographic synthesis, a bioecological analysis of the pest, and field observations. The results highlight the necessity of implementing sustainable and integrated management practices to reduce economic losses and safeguard olive groves.
Etude sur les pratiques d’utilisation du caroubier par les habitants de la region d’Ain Témouchent
(2025) Himouri, Hamida; Sebie, Soumia; Belgacem, Amel
The carob tree (Ceratonia siliqua), an evergreen tree or shrub from the Fabaceae family, is a Mediterranean species domesticated over 4,000 years ago. It is highly valued for its sugar-rich pods, which are 90% pulp and 10% seeds, making them incredibly versatile. This tree plays a significant ecological role due to its remarkable ability to adapt to water scarcity, making it ideal for reforestation in arid and degraded areas. Economically, the carob tree is immensely important because of its diverse industrial applications in the agri-food, medical, cosmetic, and chemical sectors. In Algeria, while carob cultivation is primarily found in the Saharan Atlas, it often remains marginal. According to FAO statistics for 2020, Algeria was the fourth-largest global carob producer, with an estimated 3,280 tons, accounting for about 6.6% of the total global output. These figures highlight the resource's importance and show it deserves more attention for its significant socio-economic and agro-ecological value.

(2025) Boudlal, Nourdine; Boulfedaoui, Khadîdja Sarah; Belhacini, Fatima
Natural saffron (Crocus sativus L.) is a highly prized aromatic and medicinal plant whose chemical composition is rich in antioxidants such as crocin and safranal, making it an effective ingredient in cosmetics. Saffron is used in skin care because of its anti-inflammatory and regenerative properties, and helps to brighten the skin, reduce wrinkles and treat dark spots. Its natural appeal lies in the fact that it is a safe, non-irritating botanical ingredient, which means it can be used in cosmetic creams, soaps and floral waters.
Extraction et valorisation des huiles essentielles de Ricinus communis L pour l'industrie pharmaceutique et cosmétique
(2025) Bouramena, Fatima Zohra; Belhadji, Hassen; BELHACINI, Fatima
Ricinus communis, commonly known as castor, is a medicinal plant well known for its therapeutic properties and is widely distributed across various regions of the world. Its essential oil is extracted from the seeds and is rich in ricinoleic acid. It exhibits anti-inflammatory, antimicrobial, and wound-healing properties. In the pharmaceutical field, castor oil is used as a laxative, a carrier of active compounds, and in the manufacture of certain medications. In cosmetics, it is used in creams, ointments, hair oils, and skincare products due to its nourishing and regenerative effects. The valorization of this oil supports local plant resources and promotes innovation in natural product development. In this study, we first extracted the oil as the primary product, then developed a cream formulated for treating eczema and reducing skin inflammation. This cream was tested on several individuals, and the results showed significant effectiveness in relieving symptoms and improving skin condition.
Composition biochimique globale et évaluation nutritionnelle de la chair du tilapia rouge (Oreochromis sp) élevé au niveau de la ferme piscicole d’eau douce Sarl Iyad Fish, Wilaya d’Ain Temouchent.
(2025) BENATIA, Khadra Nassima; ELMGUENNI, Amina; BOUFEKANE
In the context of diversifying food sources and strengthening nutritional security, red tilapia (Oreochromis sp) represents a major aquaculture species of interest in Algeria. The present study, conducted in collaboration with the Experimental Station for Aquatic Resources of Beni-Saf (CNRDPA) and the Technical Platform for Physico-Chemical Analysis of Ouargla (PTAPC Ouargla, CRAPC), is part of an effort to enhance the nutritional quality of this species, farmed in a recirculating aquaculture system (RAS) at the Sarl IYAD Fish farm (Ain Temouchent Province). The main objective of this work was the biochemical and nutritional evaluation of red tilapia fillets through the determination of several parameters: moisture, protein, lipid and ash content; fatty acid profile; amino acid composition; and concentrations of essential minerals (P, K, Mg, Ca, Fe, Cu, Zn, Mn, Se). Statistical comparisons were also made based on the size and sex of the 54 individuals collected between February and April 2025, including 26 males and 28 females. The analyses revealed that the flesh is very rich in high-biological-value proteins, with a marked concentration of essential amino acids (lysine, leucine, arginine, threonine and valine), and low in fat, predominantly composed of monounsaturated fatty acids (oleic acid). Although present in smaller proportions, omega-3 polyunsaturated fatty acids (EPA, DHA) provide the product with significant dietary value. Furthermore, the results showed appreciable levels of essential minerals such as phosphorus, potassium, magnesium, calcium, iron, and zinc, positioning red tilapia as a relevant food source for addressing certain nutritional deficiencies. The overall observed nutritional quality, combined with the species’ good adaptability to local farming conditions, highlights the potential of red tilapia in the development of sustainable aquaculture in Algeria. This study provides reference data valuable for the valorization strategies of fishery products while promoting the consumption of a local, accessible, and health-beneficial fish.

Impact des techniques culturales simplifiées sur le stress hydrique des céréales
(2023) Boukraa Betteyeb, Mohamed; Lahcen, Oussama; Abdellaoui, Hadjira
Cereal cultivation is an essential component of Algerian agriculture. It is primarily carried out under rainy conditions and occasionally receives supplementary irrigation. Water stress is a significant problem, particularly affecting cereal crops. To counter this stress, various measures are implemented, including the application of simplified agricultural techniques, which are the subject of our study. We have measured and compared the impact of water stress on phenological parameters and yield components of cereals under different cultivation practices, The results showed that simplified crop management under vegetative cover had an impact on water stress and consequently on all measured variables. Conservation practices could be a commendable alternative to intensify localized cereal farming in arid and semi-arid regions where water is a limiting factor.

(2023) BENGOUDIFA, Kheira Rania; ABID, Zakaria Aymen; LOUERRAD, Yasmina
Weeds are the most important biotic factor responsible for the deterioration of the quality and quantity of crop products. In this context, the objective of our work is to determine the allelopathic potential of Bromus rigidus and Sinapis arvensis weeds on the growth of four plants of agrifood interest; barley (Hordeum vulgare L.), wheat (Triticum durum L.) and tomato (Solanum lycopersicum L.) and coriander (coriandrum sativum L.). The results of our study showed an inhibitory effect of weed extracts used by a reduction in plant biomass. The inhibition of the growth of the plants studied leads us to suggest the use of the weeds studied as natural weed killers against other weeds.

(2023) BELLAHOUEL, Abdelhakim; TOUTA REZOUG, Mohamed; BUGHALEM, Mostafia
The north-west of Algeria is characterized by a very diverse biotope, which provides many benefits to its inhabitants, such as better management of rainwater, reduced air pollution and a sense of well-being. The city of Ain Temouchant includes many private gardens with a substantial plant biodiversity. To ensure sustainable development, it is important to intensify the protection and enhancement of this natural heritage. The feasibility of effectively managing the biodiversity of these areas depends on a good knowledge of their vegetation cover. This work was carried out at the level of the APC public garden, located in the town of Ain Temouchant. Its objective is the study of the flowering procession to characterize the species ordinarily living in this medium. A total of 36 plant species were counted. They are divided into 25 families. Ficus retusa is the most representative species with 28.5714286% of the total number of species. The results show that a look must be taken at the garden studied, which can be a medium for the conservation of biodiversity, for ecological and educational purposes
Etude de la croissance de quelques plantes cultivées sur différents échantillons de sol de la wilaya d’Ain T’émouchent
(2023) Achemaoui, Daheb; LOUERRAD, Yasmina
Soil plays an essential role in the function of the Earth’s ecosystem, it is essential because it provides nutrients, minerals and water to plants and animals. It is thus considered as a habitat for many microorganisms. In this context our study focuses on the study of four soil samples of the wilaya of Ain T'émouchent; two agricultural soils and two urban soils were chosen to see their effects on the growth of plants of agri-food interest ((Hordeum vulgare, Triticumdurum, Lens caulinaris, Trigonelleafoenum-graecum) and determine the relationship between soil texture and plant growth, as well as the rate of organic matter in the different soil samples. The results show that agricultural soils are more conducive to wheat and barley growth; unlike fenugreek, which has good growth on urban soil.

(2021) Mastor, Nor El Houda; Boudjenan Serradj, Halima; Louerrad, Yasmina
L’étude de l’effet du prétraitement (amorçage hydrique) des semences de blé dur sous l’influence du stress salin et du stress hydrique a été menée sur la variété (Vitron). Dans ce contexte, l’induction du stress salin a été effectuée en utilisant 100 mM de chlorure de sodium, alors que l’induction du stress hydrique a été réalisée par le polyéthylène glycol à 12.5%. Différents paramètres ont été calculés tels que le taux de germination, la longueur de la partie aérienne et souterraine, le pois sec ainsi que le poids frais. Les résultats obtenus montrent que le début de germination pour les grains amorcés de chaque stress (salin et hydrique) a été observé après 24h de l’imbibition, Les résultats après 96 h de germination montrent un taux final de 96.66% sous le stress salin et de 95.33% sous le stress hydrique. Les résultats la longueur de la partie aérienne et souterraine, ainsi que le poids sec et le poids frais montrent des différences par rapport aux témoins. Les résultats de l’expérimentation faite sur le terrain de Tamazoura, montre un taux de germination élevé a qui a été observé après un délai de 15 jours. En conclusion, que le processus d’amorçage hydrique contribue à l’amélioration du taux de germination du blé et influe considérablement sur la croissance de la plante.
Reconstitution 3D d'espèces végétales par photogrammétrie
(2022) Smaine Housseyn, Mezyane; Chenafi, Halima Essadia; KADDOUR, Hakim
La photographie prise sur les plantes pour des fins analytiques représente un document assez riche d’information ; par ailleurs elle est limitée par l’absence de l’échelle géométrique et l’angle de prise de vue. Le but de ce mémoire est de soulever cette dernière limitation et ceci par l’utilisation de la technique de la photogrammétrie terrestre basé sur le principe de la stéréoscopie 3D. En effet, en utilisant une série de photos par une caméra ordinaire après son calibrage, sur des espèces végétales de différents types, de taille et de géométrie. Nous avons pu attendre une qualité de reconstruction tridimensionnelle avec une précision 0.4 pixel malgré la complexité géométrique des espèces photographiées. Ce mémoire décrit aussi la méthodologie pratique et de traitement pour une telle reconstitution.

(2021) Daoudi, Fatima Zohra; BOULENOUAR, Fatna; Ilias, Faiza
The cultivation of grapes in Ain Temouchent reflects an interesting case, where the cultivation of several local varieties of vines is widespread without any dedicated effort. The present work aims to apply an amplometric study on several different grape varieties for the wilaya and on other different regions of the wilaya of Ain Temouchent. The aim of this study is to help identify the existing relationships between these classes and then to divide them into groups according to their differences. This study was conducted focusing on the application of a proven property related to quantitative measurements, while some of them are recorded qualitative ratings. Analysis of the data revealed to us the importance of certain characteristics, which we often believe play a major role in determining the characteristics of each species, including angles, opening of the peduncle, length of veins, shape and color. While the analysis of the principal components in addition to the hierarchical classification of groups divided these items into large groups, and the big difference was revealed between the cardinal, date palm of beyroute and Muscat Italy with Victoria Chasselas, Muscat and the Red Glob.using the program (SPSS) which aims to develop Classification of vines. The program was able to identify the groups themselves, as well as the strong relationships and differences between them.
