Aphid diversity in two food legume crops: fava bean and pea in Naciria region, and first record of <em>Melanaphis sacchari</em> (Zehntner, 1897) in Algeria

Abstract

Beans and peas are very important legumes because of their importance in human food and their high protein contents, as well as their role in the supply of atmospheric nitrogen to the soil. However, these crops are subject to various pest outbreaks, reducing their yield. The purpose of this study is to carry out an exhaustive inventory of aphids present on bean (Faba bean and Seville variety) and pea crops (Merveille De Kelvedone and Utrillo variety) in the region of Naciria (Boumerdes), in order to evaluate the diversity and abundance of aphids present in these crops. Sampling of aphid populations has been done using two trapping techniques: Barber pitfall trap and yellow traps. The results obtained express a richness of 48 aphid species, with one Melanaphis sacchari species identified for the first time in Algeria. 28 species are inventoried in the pea crop of Utrillo variety, 27 species on the Merveille de Kelvedone variety, 21 species in the bean crop of Seville variety (Vicia faba major) and 20 species on the faba bean (Vicia faba minor).

Evaluation and Diversity of Aphids on Two Tomato Crops in Tizi-Ouzou (North Algeria), and First Report of Semiaphis Dauci (Fabricius, 1775) (Hemiptera: Aphididae) in Algeria

“…According to Blondel (1975), in a given environment, when the living conditions are favorable many species are found, in which case diversity is high. Our results are in agreement with those of Bouabida et al, (2021), where the Shannon diversity index calculated in four food legume fields varies from 3.66 to 4.38 bits. The equitability tends to be 1 for both cultivated varieties.…”

Estimating the Global Geographical Distribution Patterns of the Invasive Crop Pest Diuraphis noxia Kurdjumov under Current and Future Climatic Scenarios

“…Diuraphis noxia can disperse not only over short distances by migrations, but also over long distances through international trade of crops, such as wheat, barley, rye, and oats [ 71 , 72 , 73 , 74 ]. Therefore, in the future climatic scenario, these countries with increased potential suitable areas, particularly, the UK, Russia, Canada, Sweden, and France, which showed a relatively large area of increase, should be alert to the import of the host plants and strengthen the warning and management system to prevent secondary invasion.…”

Diversité des pucerons et de leurs ennemis naturels en cultures sous serre à Tizi-Ouzou, Algérie

“…Plusieurs espèces de pucerons des Poaceae ont été capturées dans les pièges jaunes, la présence de ces espèces (R. maidis, R. padi, S. graminum, S. fragariae et S. maydis) est liée directement à la présence de leurs hôtes aux alentours et à l'intérieur des serres, tels que l'orge queue-de-rat, le maïs, le blé, l'avoine, le seigle, le sorgho, le chiendent pied de poule et le panicum. Ces espèces aphidennes de céréales ont été signalées par Bouabida et al (2020) dans la région de Boumerdès (Algérie). Les espèces R. maidis, R. padi, S. fragariae et S. maydis ont été également signalées par Ait Amar et Benoufella-Kitous (2021) dans le cadre d'une étude en culture de la pomme de terre dans 3 localités situées dans la région de Tizi-Ouzou.…”
