Titre: AVIAN BIODIVERSITY IN AN ARTIFICIAL ENVIRONMENT: CASE OF THE NOUMERATE GREEN BAND, (GHARDAÏA, ALGERIAN SAHARA) Auteur(s): CHEDAD A; BELADIS B; BOUZID A; BENDJOUDI D; GUEZOUL O Résumé: An avifaunestic count was carried out between November 2017 and October 2020. This qualitative and quantitative study at the level of an artificial environment, in the case of the green band Noumérate in Ghardaïa Nord, for an objective inventory of the birds' diversity. Indeed, 86 species have been identified, belonging to 17 orders and 33 families. The order Passeriformes is the most dominant with 15 families and 56 species, or 44.12% of the recorded species. As for Muscicapidae, the Alaudidae, are the best represented with respectively 13 and 07 species. Depending on phenological Status, 43 species Passage Visitor (50%), 25 breeding species, of which 18 are Resident (20.93%) and 7 are migratory species (8.14%). The Winter Visitor birds are represented by 17 species (19.77%) and finally, only one species of bird bears the unknown phenological status. It should be noted that at the national level, 22 species have been identified, or 25.58% are protected by executive Fiat Algerian law (N°12-235). On the other hand, internationally, two species have been found to have "Near threatened" status (Meadow Pipit and Dartford Warbler) and only one species has "Vulnerable" status (European Turtle Dove). The hybrid Sparrow is the most dominant among all the species counted, with 30.9% in 2018 and 29.9% in 2019. Shannon index values fluctuate between 3.65 bits (2018) and 3.32 bits (2019) and evenness index (E) values are relatively constant between 2018 and 2019, equal to 0.65.

Titre: CHARACTERIZATION AND EVALUATION TEST OF THE FOREST LITTER OF THE OAK GROVE (CORK OAK AND ZEEN OAK) OF EL-KALA NATIONAL PARK (PNEK), ALGERIA Auteur(s): SAMAI I; REMITA F; Nebbach S; ANGUEL I Résumé: The importance of organic matter in the soil has been highlighted for a long time. Several authors tried to define this fraction: The organic matter is the whole of the carbonaceous and nitrogenous compounds resulting from the degradation of the products of the fauna and the flora, of surface and the basement. It presents a range of very different substances and at very different stages of evolution. The National Park of El-Kala (PNEK) is known by the diversity of ecosystems that are linked to a rich and diverse plant cover dominated by forests of cork oak and Zeen oak, which provides the soil with a significant amount of organic matter in the form of organic debris not decomposed (litter). In order to know and evaluate the litter, two characteristic groups of the vegetation of cover of Ain-Bergougueya were carried out. The morpho-analytical characterization of the litter brings out the dominance of the fraction recognizable on the surface constituted essentially by the leaves and the twigs. Results showed that the chemical characterization of the litter shows that the pH varies little according to the layers; it is more acid on the surface and close to neutrality in contact with the soil, the electrical conductivity is rather low, the water content of the litter varies from one layer to another but is low on the ground. The rapid recycling of organic matter provides the plant cover with mineral salts that are essential for the maintenance and development of rich and diversified vegetation capable of providing many products that can be used by man Description: Revue des BioRessources

Titre: INVENTORY OF LADYBIRDS IN THE OUARGLA REGION AND STUDY OF THEIR PREDATORY CAPACITIES Auteur(s): BENAMEUR-SAGGOU H; BENTERBAH F; NECIRI M; REMLI M; BOUKHLAT O; CHENNOUF R; BENBRAHIM K Résumé: The inventory of the arthropodological fauna in the two agro-systems studied, i.e. the palm grove and the greenhouse, allowed us to note that the family Coccinellidae occupies the first place among the order Coleoptera with an AR% = 35,62% in the month of April in the palm grove and 40.76% in the greenhouse. The palm grove is the richest in ladybird species with 07 species reported (248 individuals) with a predominance of Pharoscymnus ovoideus (13,63%) and Pharoscymnus numidicus (13,46%). At the level of the Greenhouse, only 04 species (325 individuals) are recorded, namely Coccinella algerica (36,30%), Coccinella novomnotata (42,15%), Hippodamiatredecim punctata (15,38%) and Coccinella undecimpunctata (6,15%). The study of the predatory capacity of the ladybirds inventoried showed that Pharoscymnus ovoideus is more voracious (19,33 individuals of white cochineal/24h) compared to Pharoscymnusnumidicus. The aphidiphagous ladybirds also show different predatory abilities. Coccinellanovemnotata is the most voracious with an average of 61,67 individuals/24h. The species Coccinella algerica devours the least amount of aphids with an average of 49,67 individuals/24h Description: Revue des BioRessources

Titre: BIOECOLOGY OF Deudorix (Virachola) livia Klug, 1834 (LEPIDOPTERA, LYCAENIDAE) ON POMEGRANATE IN LOWER SAHARA Auteur(s): ALMI A; KORICHI R; REDJEL MELAH M; BRADAI Lyès; BISSATI-BOUAFIA Samia Résumé: The study of some bioecological aspects of Viracholalivia was carried out in two regions (Ouargla and Touggourt) in southeastern Algeria. On pomegranate, the infestation by this pest starts as soon as the inflorescences appear (mid-March).At the ripening of pomegranates this rate arrives at 15.01%, 16.14%, and 18.22% respectively for the years 2017, 2018 and 2019. The female generally prefers to lay her eggs in the half of the fruit close to the calyx with a preference for the southern orientation. V. livia shows polyphagy within several fruits in the surveyed palm groves. Description: Revue des BioRessources
