Item Inventaire de trois peuplements d'Orthoptères dans le Parc National de Taza (Jijel, Algérie)(2013) Moad, ROUIBAH; Salaheddine, DOUMANDJIDans ce travail, un inventaire exhaustif des Orthoptères du Parc National de Taza (Algérie) a été établi. La méthode utilisée est celle de dénombrement sur quadrats de neuf mètres carrés de surface à raison d’un par station et par mois en réalisant à chaque fois cinq répétitions. Le présent travail a été réalisé dans une friche à Taza, une garrigue à Tifraouene et un maquis à Guerrouch. 24 espèces au total ont été recensées réparties entre 22 Caelifères et 2 Ensifères. La majorité des Caelifères sont des Acrididae. Cette dernière est répartie principalement entre trois sous familles: les Oedipodinae, les Gomphocerinae, et à un degrès moindre les Acridinae, et ce notamment à Tifraouène et à Guerrouch. La richesse spécifique à montré que les stations de Taza et de Tifraouène possèdent respectivement 17 et 18 espèces, Guerrouch par contre, est relativement moins riche avec 14 espèces uniquement.Item Analyse de la compétitivité de la filière de viande de volailles en Algérie : tentatives d’explication d’une déstructuration chronique(2013-06) KACI, Ahcène; CHERIET, FouedDans cet article, nous nous basons sur les apports théoriques des approches Porterienne et RBV pour expliquer la non-compétitivité de la filière avicole algérienne. Sur le plan empirique, notre travail est axé sur deux séries d’enquêtes par entretiens, menées en 2007 et en 2010. Les principaux résultats dégagés mettent en exergue une dépendance quasi-totale du modèle avicole intensif vis-à-vis du système agroalimentaire mondial, la faiblesse technique de la compétitivité des élevages avicoles, l’absence d’organisation de la profession et l’incapacité d’innovation de l’ensemble des acteurs de la filière à la fois sur un plan technique et surtout sur le plan organisationnel. Ce travail a, entre autres, permis d’identifier les facteurs susceptibles d’assurer une meilleure compétitivité du modèle avicole algérien à l’ère de la mondialisation et de la régionalisation.Item FOOD DIET OF DOCIOSTAURUS MAROCCANUS THUMBERG, 1815 (ORTHOPTERA, ACRIDIDAE) IN ITS GREGARIOUS STATE: A STUDY IN SIDI BELABBES REGION, ALGERIA (2010)(2014) CHAOUCH, A; DOUMANDJI-MITICHE, Bahia; ALLAL-BENFEKIH, LThis study of diet and food preferences in the gregarious phase of Dociostaurus maroccanus (THUMBERG, 1815), was carried out in the wild during the months of June and July 2010 in the region of Marhoum (State of Sidi Bel Abbes). The determination of the diet and food choice was made by the method of faeces content analysis, which is based on the recognition of epidermises fragments of the consumed plants, using alight microscope. The results of this study show that D.maroccanus is a polyphagous species whose adult have a tendency to overconsume of Poaceae (Gramineae). Poaceae account for a large part in the diet of adult males and females of the gregarious populations with over 60% of the total food spectrum, compared with the other consumed plant families which are very diverse but whose consumption frequencies are very low. Regardless of the plant species, males and females show no specific food choices, especially in the consumption of Dicotyledons. Among Poaceae species, and compared to other species, Lolium multiflorum is highly consumed both by males and females, with the exception of Stipa parviflora whose frequency of consumption is different.Item PHASAL STATE OF SCHISTOCERCA GREGARIA FORSKAL, 1775 (ORTHOPTERA, ACRIDIDAE) IN THE BREEDING BIOTOPES OF ALGERIAN SAHARA DURING 2009 AND 2010(journal, 2014) BENSAAD, H; DOUMANDJI-MITICHE, BahiaTo better understand the trend of locust populations existing in southern Algeria during the calm periods (recession), a study on the phase status of locust populations of Schistocerca gregaria in its natural biotope, was carried out during the two years 2009 and 2010. To do this, morphometric measurements of 163 Locust individuals including 81 males and 82 females, from eight different biotopes, were performed. The mean values of morphometric ratios of Elytron on Femur (E / F) and Femur on Cephalic capsule (F / C) in the 8 study sites fluctuate in males from 2.02 to 2.13 for the E / F ratio and 3 65 to 3.95 F / C ratio. For females E / F varies between 2.09 to 2.15 and F / C varies between 3.83 to 4.03. The comparison of the results related to E / F ratios and F / C with those of Dirsh (1953) and the report on their morphometric abacus of Duranton and Lecoq (1990) showed that male and female populations that evolve in the biotopes of both southern and central parts of the Algerian Sahara, for the two years 2009/2010 are mostly the Solitarious-transient with a rare presence of purely solitary individuals and a total absence of gregarious individuals.Item THE INTERACTION OF L5 LARVAE OF LOCUSTA MIGRATORIA (LINNAEUS, 1758) (OEDIPODINAE, ACRIDIDAE) WITH BIOBESTICIDES(TRANS STELLARI, 2014) OUTTAR, FAHIMA; MAHDJOUBI, DJILLALI; BISSAD, FATMA; MOUHOUCHE, FAZIA; DOUMANDJI-MITICHE, BahiaOur work is based on the use of three biopesticides belonging to three different categories, a fungus Metarhizium anisopliae var acridum a IGRs Triflumuron (TFM) and an excerpt from the henna plant Lawsonia inermis, on L5 larvae of Locusta migratoria applied with the two modes of penetration, contact and ingestion. For this, we tested their effect on the morphology and mortality. The results show us that the three biopesticides involved morphological deformations and a total mortality of 100% in the L5 larvae.Item BIODIVERSITE ORTHOPTEROLOGIQUE DANS QUELQUES STATIONS DU SAHARA ALGERIEN (BISKRA, ADRAR, DJANET ET TAMANRASSET)(2014) DOUMANDJI-MITICHE, Bahia; DOUMANDJI, Salaheddine; CHEBLI, A; ABDOUALI, R; KOURIM, M.A; SID-AMAR, AHMED; DOUMANDJI, SLa biodiversité orthoptérologique en Algérie est remarquable et varie quantitativement et qualitativement d’un étage bioclimatique à un autre. Nous nous sommes intéressés plus particulièrement à l’acridofaune de 4 régions du Sahara algérien appartenant à l’étage bioclimatique saharienne à hiver tempéré. Il s’agit de Biskra, située à 450 Km au S.E. d’Alger, d’Adrar située à 1543 Km au S.W. de la capitale, Djanet distante de 2000 km au sud est algérien et de Tamanrasset se trouvant à l’extrême sud algérien à 2200 Km d’Alger. Au cours de nos échantillonnages pour l’étude du criquet pèlerin Schistocerca gregaria Forskal, à l’état solitaire et grégaire et du criquet migrateur Locusta migratoria cinarescens nous avons noté 27 espèces d’orthoptères à Biskra dont Sphodromerus cruentatus, 32 à Adrar citons Pseudosphingonotus savigny, 11 à Djanet avecTridactylus variegatus et 19 à Tamanrasset dont Poecilocerus bufonicus hyeroglyphicus.Item ORTHOPTEROLOGIC FAUNA OF OUARGLA OASIS(TRANS STELLARI, 2014) BELHADJ, HAMIDA; DOUMANDJI-MITICHE, Bahia; GUENDOUZ-BENRIMA ATIKA, ATIKAOrthopterologic populating study has been conducted in 3 stations of Ouargla Oasis situated in south-west of Algeria. Orthopteras Samplings are realized every fortnight from September 2001 until August 2002. This inventory is completed by floristic statements for each station. 18 orthopteras species were inventoried with 16 Caeliferae where 14 belong to family of Acrididaes and so 2 species of Ensiferae belonging to Gryllidae family. Study of total and middle richness shows variation according to stations and to samplings periods. The most important yearly centesimal frequency is pronounced for Pyrgomorpha cognata specie in both palm groves, and for Acrotylus patruelis specie in the cultivated ground of Experimental farm. of Hassi Ben Abdullah. Constancy of Orthopterologic species varies from station to another. However, two species are constant for the three stations, which are Pyrgomorpha cognata and Ochrilidia gracilis. The most important diversity index is 1.66 bits in June month for Mekhadma station. Equitability values are all closer of 1. corresponding to populations in balance between them. The contagious distribution of individuals is the most characteristic. Through factorial analysis of correspondences, we have noted that orthopterologic species are spreading according to their ecologic affinitiesItem Diversity and Ecology of Orthoptera of Some Agricultural Areas in Northern Algeria(2014) HAMADI, Kamel; DOUMANDJI-MITICHE, BahiaA study on the orthopterologic diversity was performed in three different agro-ecosystems in northern Algeria, located at Baba-Ali, Ain-Taya and Cap-Djinet. The first two stations are part of the plain of Mitidja. Inventories carried out were conducted over a period of 12 months; November-December 1996/1997 for Baba-Ali and Ain-Taya stations, and September-August 2010/2011 for Cap-Djinet station. The settlement of the identified orthopteric revealed a total of 25 species, 8 Ensifera and 17 Caelifera. Acrididae Family accounts only 15 species are spread over 6 subfamilies, 60% of the identified orthopterofauna. The highest total richness and the specific average richness per survey and station values were recorded in October 1997: 8 – 4, 2 Baba-Ali, 10-5,2 Ain-Taya; and in August 2011: 13 – 6,2 Cap-Djinet. According to the Shannon-Weaver diversity index, the surveyed areas have a diverse orthopterofauna particularly in spring and autumn when the number of individuals is equally distributed between species (0,62 < E < 0, 97).Item HISTOPATHOLOGICAL EFFECTS OF AN ALGERIAN STRAIN OF BACILLUS THURINGIENSIS ON THE GUT OF ANACRIDIUM AEGYPTIUM ( ORTHOPTERA, ACRIDIDAE). INTEREST FOR BIOLOGICAL CONTROL(2014) SAIDI-TOUATI, MAHDIA; NATECHE, FARIDA; ABDERRAHMANI, AHMED; HAMADI, KAMEL; GEORGE, COLAS; BOUFERSAOUI, ABDELKADER; DJENANE, ZAHIA; HAMMANA, SOUKAINA; DOUMANDJI-MITICHE, BahiaLocust’s biocontrol requires identification of efficient bacterial strains able to be used against these ravagers. In this study, we analyzed the impact of an algerian strain of B. thuringiensis called TIM14 on the gut of Anacridium aegyptium. We observed that A.aegyptium infestation with TIM14 induced a lytic activity on the tegument and the cuticle followed by insect’s demise. In conclusion, our results suggest that the local B.thuringiensis strain TIM14 would be active through different enzymatic activities involving the chitinase that induces death of this orthoptera.Item DIET’S STUDY FOR SCHISTOCERCA GREGARIA (FORSKAL, 1775) (CYRTACANTHACRIDINAE, ACRIDIDAE) AT LEVEL OF BOTH STATIONS IN REGION OF TAMANRASSET (HOGGAR)(2014) LAZAR, M; BENSAAD, H; DOUMANDJI-MITICHE, Bahia; BENZEHRA, AVegetation interest for desert locust Schistocerca Gregaria studied by analyse method of digestive continuous at level of the two stations (Oued Amdad and Oued Arak) situated in region of Tamanrasset (Hoggar) in Algerian South known as zones of reproduction of potentilla closer each other and are different by dominance of various vegetable species which are growing, showed in spite of presence of several vegetable species at level of both stations, diet of solitary locust populations harvested in both study stations is not very varied and only 4 vegetable species at Oued Amded and 6 ones at Oued Arak had been observed in ingestion of studied individuals. As well, at level of Oued Amded station, females have consumed 4 vegetable species and males have consumed only 2 among the 12 existing. In station of Oued Arak, females and males have consumed 5 vegetables species on the 10 existing. The most consumed vegetable specie as well as by females and by males in both stations is Schouwia thebaica.Item Host Plant Determination of Brachytrupes megacephalus Lefebvre, 1827 (Orthoptera, Grillinae) Using Faeces Analysis in the Region of Oued Righ (Algerian Sahara)(American-Eurasian J. Agric. & Environ. Sci., 15 (2): 271-277, 2015, 2015) Lakhdari, Wassima; DOUMANDJI-MITICHE, Bahia; Dahliz, A; DOUMANDJI, Salaheddine; Bendifellah, L; Bouchikh, Y; Hammi, H; Soud, A; MlikIn the southeast of the algerian Sahara (Touggourt), the host plant determination of Brachytrupes megacephalus was studied by faeces analysis (microscopic observations). The experimentation was conducted in mid August until the end of September 2014. The main results of faeces analysis showed that the plants consumed by B. megacephalus belong to 8 families: Arecaceae (Phoenix dactylifera), Apocynaceae (Nerium oleander), Asteraceae (Chrysanthemum), Myoporaceae (Myoporum sandwicense), Plumbaginaceae (Armeria maritima), Rosaceae (Prunus armeniaca), Solanaceae (Solanum lycopersicum) and Triochylaceae (Cherry fantasia and White Kristina). Phoenix dactylifera is the most preferred host species by the adults of Brachytrupes megacephalus, with a consumption rate 85,87%.Item Acaricidal Activity of Aqueous Extracts against the mite of date palm Oligonychus afrasiaticus Meg (Acari: Tetranychidae)(Journal of Medicinal Plants Studies 2015; 3(6): 113-117, 2015) Lakhdari, Wassima; Dehliz, A; Acheuk, F; Soud, A; Hammi, H; Mlik, R; DOUMANDJI-MITICHE, BahiaThe use of chemical products to fight against insects raises several concerns related to the environment, human health, non-target species and development of resistant pest populations. The use of bio-pesticides may reduce the risks of pests and safeguard biodiversity. This experiment was conducted with the objective to study the effect of aqueous plant extracts from the southeast region of Algeria (Zygophyllum album L, Cotula cinerea Del and Limoniatrum guyonianum Del) on the mortality of the date palm mite (Oligonychus afrasiaticus). The trial was conducted at the Laboratory of Plant Protection of INRAA. The five doses (1%, 2%, 3%, 4%, and 5%) were tested on adults of phytophagous. The results show that the extracts of plants and C. cinerae and L. guyonianum do not show an effect on the pest. Unlike, Z. album showed a very significant effect on the mite by a mortality rate of 76%.Item Orthopterological Fauna in theRegion of Djelfa (Algeria)(2015) Saad, Benmadani; Ahlem, Guerzou; DOUMANDJI-MITICHE, Bahia; Salaheddine,DoumandjiFollowing the study of Orthopterological fauna in the region of Djelfa (Algeria),33 species have been listed. Calculation of centesimal frequency index showed that dominant species vary from station to another. In Faid El Botma, the dominant species is Tmethis pulchripennis (26,7 %. In station of Moudjebara, the species of Euryparyphes quadridentatus (18,6 %) %) is the most dominant. As fo Mesrane, Oedipoda miniata is on top of the list with 18.3%. At level of Ain El Ibel, the dominate one is Pyrgomorpha cognata (10,9 %). In Messad, there are two dominant species, it is about Acrotylus patruelis (26,15 %). Using the noticed that Orthopterological species inventoried, present different distribution types according to stations and months of sampling. Some species are other are random or contagious.Item Morphological Study of Different Developmental Stages of Brachytrupes megacephalus Lefebvre, 1827 (Orthoptera, Gryllidae) and Their Development in Oued Righ Region (Algerian Sahara)(journal international, 2015) Lakhdari, Wassima; DOUMANDJI-MITICHE, Bahia; Acheuk, Fatma; Dehliz, Abderrahmene; M’lik, Randa; Soud, Adila; Hammi, HamidaIn the Southeast of the Algerian Sahara (Touggourt), a morphological study of Brachytrupes megacephalus was conducted during 2014. According to the damages caused by this cricket through deviation and loss of irrigation water due to deep tunnels dug and damage crops, we found it useful to identify the insect and study the external appearance of this cricket. The results show that B. megacephalus has an annual life cycle with five nymph stages. The mating season is placed normally from mid-March to mid-April. The eggs are with an ovoid shape and a greenish color measured by 3.5 to 4 mm, First nymph stage is with a transparent colors which has a pronotum measured between 1.5 and 2.2 mm with a head between 3 and 4,6 mm and the femur has a length of 5 to 6 mm. Unlike the other nymph stages are yellow-orange with a darker head than the rest of the body. The adults of this cricket have a pronotum of 5 to 6 mm, the head is between 13 to 14 mm and the femur is from 17 to 22 mm. All these post-embryonic development mature throughout the summer until September, during which the cricket becomes imago.Item Morphology and structure of adult male genitalia of Brachytrupes megacephalus Lefebvre, 1827 (Orthoptera, Gryllidae) in the southeast of Algeria(Journal of Entomology and Zoology Studies 2015; 3(6): 355-359, 2015) Lakhdari, Wassima; DOUMANDJI-MITICHE, Bahia; Acheuk, Fatma; Dehliz, Abderrahmene; Hammi, Hamida; M’lik, Randa; Soud, Adila; DOUMANDJI, SalaheddineDepending to the few and old data which have been conducted on the body morphology of Brachytrupes megacephalus Lefebvre, 1827 (Orthoptera, Gryllidae), we have investigated the structure of male genitalia in Algerian Sahara species to establish a basis for morphological study. The study was conducted in the laboratory of entomology in the experimental station of Sidi Mehdi. After isolation of the male genital apparatus, we find that its structure is consisted by the testis, accessory gland, ejaculatory duct and the phallic complex. The last organ is composed of epiphalus, guiding rod, ectoparamere, endoparamere, dorsal and median pouch. The spermatophore produced by Brachytrupes megacephalus was investigated in detail. Besides the study of the spermatophore size (8 mm), morphology, and formation, spermatophore is composed of the ampulla (3.9 mm), attachment plate (2.8 mm) and the tube (1.5 mm). The present paper aims to improve this information, on the species of B. megacephalus.Item Diversity and Richness of Rodent Communities in Various Landscapes of Touggourt Area (Southeast Algeria)(2015) Moussa, Hadjoudj; Karim, Souttou; Salaheddine, DOUMANDJIOur study presents the species diversity of rodent communities from palm groves and sand dunes in a desert area (Touggourt, Southeast Algeria). Samples were collected from four stations: two sites of sand dunes and tow sites of palm groves. The method of random trapping was performed using 24 cages of Besançon Technique Service (BTS) installed at each station. All captured species were of the family Muridae and belonged to two subfamilies: Murinae and Gerbillinae. The most common species at all stations was Gerbillus nanus (31 specimens), followed by Rattus rattus (23 specimens) and Gerbillus tarabuli (18 specimens). The murine species Rattus rattus and Mus spretus were found at agriculture sites (palm groves) while the Gerbillinae Gerbillus nanus, Gerbillus gerbillus and Gerbillus tarabuli preferred natural environments (sand dunes) where the soil was light and sandy.Item ANTAGONISTIC ACTIVITY OF TWO BACILLUS SP. STRAINS ISOLATED FROM AN ALGERIAN SOIL TOWARDS THE MIGRATORY LOCUST LOCUSTA MIGRATORIA (LINNAEUS 1758)(2016) OULEBSIR-MOHAND KACI, Hakima; TALBI-KHEMILI, Souad; GANA-KEBBOUCHE, Salima; DOUMANDJI-MITICHE, BahiaThe aim of our study is to isolate, purify and characterize two entomopathogenic bacterial strains of the genus Bacillus from the soil of Adrar in the Algerian Sahara. The molecular characterization of the isolated strains was carried out by DNA isolation, PCR and sequencing of 16S rRNA gene, followed by a phylogenetic analysis. After that, the study of the bacteria toxicity on the fifth larvae stage of Locusta migratoria was conducted by assessing rates of mortality, LT50 and LC50. The phylogenetic analysis showed that the two strains (Strain-B1 and Strain -B2) were identified as Bacillus sp. (HE799656) and Bacillus sp. (HE805963), respectively, with a very high similarity (99%) with the strains Bacillus thuringiensis (NR_043403) and Bacillus weihenstephanensis (NR_024697). Besides, the results of toxicity tests showed that larvae of L. migratoria are influenced by the two isolated bacterial strains. This action is more pronounced with the Bacillus sp. strain-B1 (HE799656) compared to Bacillus sp. strain-B2 (HE805963). Examination of TL50 shows that these times vary depending on the bacteria and concentrations applied. Similarly, the LC50 are closely related with time and they also vary depending on the bacterial strain tested.Item Impact of Jacobiascalybica’sattacks on the physiology of the vine leaf.(2016) Guendez-Kermia, Ramila; Setbel, Samira; Morsli, Samira; DOUMANDJI-MITICHE, BahiaDuring the inventory undertaken in Algeria on the vine, the green leafhopper proved to be a new bio aggressor on this crop. Indeed, the first observations on vines date back to July 2002 and renewed in 2003 and 2004 [4], in the vineyards of the Western Mitija where the insect has spread rapidly throughout the country ([6]; [7]; First data JacobiascaLybica ( Bergevin&Zanon ) (Homoptera , Jassidae ) on Vine in Algeria; [8]). Jacobiascalybicaresponsible of the grillure on the vine leaves, generates considerable damages on the leaf after each attack. Given the climate change,These studies were made during the wine-making campaigns on 2013, 2014 and 2015 and having for objectives of: · Consolidate the searches undertaken during the wine-making campaign in 2007, on the fluctuation in the populations of the green leafhopper, responsible of the grillure but this time on the grape varieties of local product not imported one and observe the effect of the climate change on this harmful. · Determine the influence of the vigour of stocks and their sensibilities to this insect. · Demonstrate the effect of the attacks of this devastator on the limb physiology. These studies were conducted through the seasonal evolution of the green leafhopper on the vine variety: cinsaut, grenache and carignan by accounting larvas on the young and old leaves of the same vine variety studied by using the similar attractive traps to the sexual traps type INRA. They are established by a plastic shelter in the shape of tent, at the bottom there is a sticky sheet. The shelter is of bright yellow color. This technic permits to trap the green adults of leafhopper by chromatic attraction. The samplings were made once a week during three wine-producing campaigns, on 2013, 2014 and 2015 by making a periodic enumeration of larvas and adults. They were been realized in Hadjout, the Metidja and Mascara (west of Algeria). This study showed the succession of four peaks from May to September in Hadjout on the carignan wine which pilosity on the lower face of the limb has compared with cinsault and Grenache. Indeed the numbers of the green leafhopper on carignan especially in second generation exceed widely the recommended threshold. Moreover, it would seem that thelest vigorous vine to this leafhopper: Carignan accuse a strong depigmentation of the limb 50% followed with 40% and 10% respectively by Grenache and cinsault. However, no presence was revealed on the same vines of Mascara with 0% for all vignard. These studies allowed us to conclude that the populations evolution of the green leafhoppers depends of several factors such as the temperature, vigor of the vineand hairiness of its limbus.Item FIRST APPROACH FOR STUDYING THE IMPACTS OF THE NUCLEAR TESTS ON INSECTS IN REGGANE, ALGERIA(2016) CHEBLI, A; Einor, D; Owens, M. C; DOUMANDJI, Salaheddine; DOUMANDJI-MITICHE, Bahia; Mousseau, T. AHerein, we report the initial findings of a study of two insect species (the Sahara bee Apis mellifera sahariensis and the silverfish Lepisma saccharina) collected from the site of the 1960 Reggane nuclear test site in Algeria. These samples were analysed via single-cell electrophoresis for DNA damage resulting from radiation exposure due to nuclear tests. Our results show statistically significant variation (p<0.001) in DNA damage in the silverfish compared to control organisms, but no such effect was found in the Sahara bee. This study represents what we believe to be the first of its kind regarding the ecological effects of the 1960 Reggane nuclear test and will be expanded upon in future research. Overall we call for further in-depth studies of the desert populations of various taxa including birds and mammals.Item Biocontrol test against the leaf minerof tomato Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) by using entomopathogenic fungi in the Algerian Sahara(2016) Lakhdari, W; Dehliz, A; Acheuk, F; Mlik, R; Hammi, H; Matallah, S; DOUMANDJI-MITICHE, BahiaDevastating insects constitute one of strains for cultivate tomato. Among these insects, tomato leafminer (T. absoluta) has been recently introduced in Algeria (2008), it constitute a challenge for both agricultures and scientists. Firstly, this insect is introduced without their natural enemies which may reduce their damage. Secondly, this species has developed insecticide resistance to many active matters. To contribute to establish a control strategy for T. absoluta we have made an inventory of their enthomopathogenic fungi. Two fungi were identified among others taken from adults and pupae. These fungi are Aspergillus flavus and Fusarium sp. A study was conducted in laboratory of plant pathology to recognize the efficiency of these antagonists. These species had unregistered a mortality mounts of 100 % in 6 days.
