Inventaire de trois peuplements d'Orthoptères dans le Parc National de Taza (Jijel, Algérie)
(2013) Moad, ROUIBAH; Salaheddine, DOUMANDJI
Dans 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.

Locust’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.

(TRANS STELLARI, 2014) BELHADJ, HAMIDA; DOUMANDJI-MITICHE, Bahia; GUENDOUZ-BENRIMA ATIKA, ATIKA
Orthopterologic 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 affinities

(2014) HAMADI, Kamel; DOUMANDJI-MITICHE, Bahia
A 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).

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.
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, Bahia
To 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.

(TRANS STELLARI, 2014) OUTTAR, FAHIMA; MAHDJOUBI, DJILLALI; BISSAD, FATMA; MOUHOUCHE, FAZIA; DOUMANDJI-MITICHE, Bahia
Our 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.
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, L
This 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.

(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, Bahia
The 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%.
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, Hamida
In 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.
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, Salaheddine
Depending 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.

(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; Mlik
In 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%.
Diversity and Richness of Rodent Communities in Various Landscapes of Touggourt Area (Southeast Algeria)
(2015) Moussa, Hadjoudj; Karim, Souttou; Salaheddine, DOUMANDJI
Our 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.
A molecular phylogenetic and phylogeographic study of two forms of Calliptamus barbarus (Costa 1836) (Orthoptera: Acrididae, Calliptaminae) from two regions of Algeria
(2016) Moad, ROUIBAH; Alejandro, López-López; Juan, José Presa; Salaheddine, DOUMANDJI
Calliptamus barbarus (Orthoptera: Acrididae) is the most polymorphic species within the genus Calliptamus. It shows a morphological polymorphism (three hind femoral spots, or only one hind femoral spot). Several studies have been made in order to distinguish the two forms: morphometry, number of ovarioles, sound production, protein and enzyme system. The aim of our work is to assess whether the two forms can be considered as different taxa and to perform a molecular phylogenetic study of two populations of C. barbarus collected from two different Algerian localities. No clear genetic differentiation was found between the samples with different morphologies. Additionally, the samples from Algeria do not form a monophyletic sister clade compared to the one formed by the sequences from GenBank from other geographical regions. Despite the morphological differences shown between the two populations, our molecular study indicates that there are no differences at a molecular level using the two mitochondrial genes COI and 16S.
Importance of solitarious desert locust population dynamics : lessons from historical survey data in Algeria.
(2016) LAZAR, Mohamed; PIOU, Cyril; DOUMANDJI-MITICHE, Bahia; LECOQ, Michel
The desert locust, Schistocerca gregaria (Forsk al) (Orthoptera: Acrididae), is a major pest and well known in its gregarious phase. However, it is not well understood during recession periods, when the solitarious phase populations are discrete. Nonetheless, these populations are at the origin of the invasions when ecological conditions become favourable. This lack of knowledge of the solitarious phase individuals impedes effective preventive management of this pest. Archive data collected in Algeria from 1980 to 2011 were used to analyse solitarious population dynamics across the Algerian Sahara where some outbreak areas are located that play a major role in the invasion process. The results confirm previous empirical observations on solitarious population dynamics. First, a clear difference could be documented between the northern and southern Saharan regions of Algeria concerning the locust dynamics and the impact of environmental conditions. The importance of runoff was clear to create suitable habitats over a long period and to very distant places from rainy areas. Second, a link, on an annual basis, between green vegetation and presence of solitarious locusts was found. Third, statistical relationships between various locations demonstrated a clear regional dynamics. Our study confirmed the importance of migrations of solitarious populations among Algerian regions and more generally within the recession area of this species. The operational implications of these findings are multiple. First, they confirm the need of a flexible and scalable preventive system during the year, from 1 year to another and with a clear distinction between the northern and southern Saharan areas of Algeria. Second, they also confirm the necessity for the inclusion of wadis and soil moisture estimations from remote sensing in geographic information systems for preventive management. And third, they clearly illustrate the importance to target solitarious locusts for more efficient preventive survey operations.

(IJIAR, 2016) HAMADI, Kamel; DOUMANDJI-MITICHE, Bahia
A 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).
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, Bahia
Devastating 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.
