A field experiment designed to assess the biodiversity related to nettle strips closed to crops, and more particularly the aphid and related beneficial populations, was established in experimental farm located in Gembloux (Belgium). Margin strips of nettle (Urtica dioica) closed to wheat (Triticum aestivum), green pea (Pisum sativum) and rape (Brassicae napus) fields were investigated. The diversity, abundance of aphids and related predators were analysed according to the plant crop species and the differential pesticide application (treated plot and control). Insects were visually observed every week during all the cultivation season. Two main families of aphidophagous predators were found in all field crops and nettle, the Coccinellidae and Syrphidae. The diversity of the aphidophagous predators was shown to be higher on nettle than in field crops, particularly the Chrysopidae, the Anthocoridae and the Miridae. However, a striking difference of ladybird abundance was observed according to the aphid host plant. In one side, Coccinella septempunctata was much more abundant on Acyrthosiphon pisum infested green pea than on the other host plant species. At the opposite, higher occurrence of Harmonia axyridis was observed on the aphid infested nettle plants than on the crop plants. In particular, none of H. axyridis was found in wheat crop. Also, more than only a significant positive correlation between predator and aphid abundance, specialised relations between particular aphid species and some so-called generalist predators was determined in the fields. Finally, intraguild interactions between the aphidophagous predators was assessed and shown that only a significant negative correlation between Episyrphus balteatus and H. axyridis related to the nettle aphid, Micrlophium carnosum, was observed. The relative distribution of the ladybirds, namely C. septempunctata and H. axyridis according to the host plant, nettle strips and crop plots was discussed in relation to integrated pest management approach.

Les marges sud et nord du Sahara sont soumises à des processus de dégradation anciens attestés par de nombreux travaux de terrain. Ils coïncident avec l'occurrence d'une sécheresse sévère sur les 3 sites d'étude, débutée dans les années 1970 en Algérie (piémont sud de l'Atlas Saharien), au Maroc (bassin de l'oued Dadès) et en Mauritanie (lac d'Aleg, Brakna). Les suivis diachroniques par télédétection satellitaire (Landsat et SPOT) et aérienne (1954 à 2002) et des observations récentes, montrent la pérennité voire l'extension de certaines zones de dégradation localisées à proximité des agglomérations et points d'eau, malgré le retour des précipitations. Le rythme et les modalités de développement des dynamiques en œuvre, qui prennent la forme d'une dégradation qualitative et quantitative des couverts végétaux steppiques et de savane ainsi qu'une revivification des dunes d'Aleg, attestent du rôle prépondérant de certains activités humaines dans les processus de dégradation de ces milieux, en corrélation avec la crise climatique dont on peut se demander si elle n'est pas devenue un facteur secondaire. Sans ignorer les enjeux socio-économiques de développement, notre démarche vise à comprendre les logiques d'action des dynamiques complexes parfois abusivement désignées sous le terme simplificateur de «désertification».
