No full textThe objective of this study is to contribute in assessing and monitoring drought’s vulnerability by developing a GIS-based model to determine vulnerable areas to this natural hazard; the model utilizes a series of agricultural, statistical, meteorological and remotely sensed data, using GIS weighed ponderation and multicriteria analysis decision making, with the integration of three components: climatic sensibility, soil sensibility and socioeconomic sensibility. The result is a vulnerability map classified into five classes according to pixel values. Very Vulnerable class forms 19.46% of the study area, vulnerable class forms 32.81% and 21.37% of the area is not vulnerable, the study presents a modeling procedure of which the final results provide to researchers, users and decision makers important information on the environmental situation of the study area, for better prediction, and risk management
Assessment of Biotope Suitability of Desert Locust (Schistocerca gregaria) in the Region of Hoggar (Southern Algerian Sahara)
No full textUpsurges of desert locusts can cause heavy economic and agricultural losses and threaten the food security of millions of people over dozens of countries. Therefore, monitoring and spatial delimitation of their habitats are necessary for biological control studies and sampling, especially on large surfaces. This study aimed to assess and map suitable biotopes for desert locusts in southern Algeria, through a GIS tool, by integrating multicriteria analysis (Analytical Hierarchy Process) as a decision-making tool for preventive methods, biological control and research. The result is a resolution map, classified into four different zones according to pixel values. The results revealed that 28.51% of the study area is an unsuitable biotope for desert locusts, 35.92% is a survival biotope, 19.5% is a suitable biotope mainly for breeding and eggs lying and 16.05% is highly suitable for desert locust gregarization and concentration. This study offers a simplified mapping procedure to assess locust habitats for decision-making and studies in large areas
Diversity of cereal pests (wheat and barley) grown in arid climate in Ziban region (provence of Biskra – southeastern Algeria)
No full textThis study investigated cereal pests (wheat and barley) grown in southeastern Algeria’s arid climate. Using three sampling techniques (yellow pan traps and Pitfall traps, a comprehensive collection of insect specimens was obtained, comprising 2526 individuals taxonomically classified into 20 distinct species, 15 genera, ten families, and six orders. Homoptera and according to quantitative analysis, Thysanoptera was the most dominant taxa, with six and four occurrences, respectively. In contrast, the dominant species were Mayetiola destructor (Say 1817) (Diptera, Cecidomyiidae) with 412 specimens, Rhopalosiphum maidis (Fitch 1856) (Homoptera, Aphididae) with 404 specimens then Oulema melanopa (Linné 1758) (Coleoptera, Chrysomelidae) with 342 specimens. The observed and expected species richness diversity parameters were comparatively more significant in the cereal ecosystem cultivated in the El Outaya location than in the Sidi Okba location. (Kruskal–Wallis, df = 3, P = 0.019). The results obtained from the Generalised Linear Models (GLM) indicated a statistically significant variation in species richness across the different sites and crops (wheat and barley) (df = 3, Mean Square = 47.70, F = 3.58, P = 0.020).While there were very significant differences in the average number of individuals per species (N/S ratio) (df = 3, mean square = 22.08, F = 5.526, P = 0.002). Species richness extrapolation revealed that diversity is anticipated as the number of individuals captured increases, however, at a slower rate as the sampled population increases. The species distribution showed that some insect species are found at all phenological stages and all sampling sites.

Mylabrini diversity and host plants in a Saharan oasis ecosystem with an updated checklist of Meloidae from Algeria (Coleoptera)
No full textThe Mylabrini and Lyttini species (Meloidae family) of the oasis of Ouled Djellal were recorded: Croscherichia litigiosa (Chevrolat, 1840), C. gilvipes (Chevrolat, 1840), and Mylabris impressa Chevrolat, 1840, Alosimus cfr. viridissimus (Lucas, 1846). The host plants feed by these species are recorded. Moreover, an updated checklist of the blister beetles from Algeria is published
Diversity of Aphids Associated with Field and under Greenhouse Crops (Wheat, Barley and Chili Pepper) across the Dryland Climate in Algeria
No full textThe aim of this study was to investigate the diversity of aphids associated with the field and under greenhouse crops in an arid climate in southeastern Algeria (Biskra province). Using yellow basins for the insects sampling, a total of 6683 specimens of aphids were collected and identified into 33 species, five (05) subfamilies: Aphidinae, Pemphiginae, Chaitophorinae, Pterocommatinae, and Greenideinae; and six tribes: Aphidini, Macrosiphin, Pemphigini, Panaphidini, Chaitophorini and Greenideini, and 22 genera. The Macrosiphini tribe is quantitatively most dominant with 20 species (61%) of the inventoried aphid population, followed by the aphidini which groups together 9 species representing 27% of the aphids inventoried. The other tribes are less represented, including one species for each tribe (12% in total). Aphis gossypii was the predominant species 29.67% of the inventoried species, followed by Rhopalosiphum maidis (15.22%) and Rhopalosiphum padi (15.07%). In terms of total wealth (S), there was a strong and positive correlation between the diversity of aphids and crops (R2 = 0.73), and also a significant relationship (df = 15, Pr > F = 0.024). Shannon’s index spatial interpolation indicates a higher diversity on agricultural lands in the study area. Shannon’s diversity and evenness index values were greater in pepper under greenhouse in Dhibia station (H′ = 2.01, E = 0.84) compared to barley and wheat, in El Haouch and Saada, respectively (H′ = 1.18, E = 0.30 and H’ = 1.45, E = 0.21)
