Opis:
Upsurges 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.

Opis:
The 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).
