    Diversity and distribution of the hymenopterofauna in northern and western Algeria
    (University of El Oued, 2020) Ghobrini, Khadjidja; Bendifallah, L.; Marniche, F.; Saharaoui, L.
    The study of the Hymenoptera fauna associated with the Fabaceae is carried out in different environments in the Northern and Western Algeria. Insect sampling was carried out at seven sites representing three regions with different ecosystems and bioclimatic stages, namely: Algiers, Boumerdes and Tissemssilt. The results obtained show a total of 1022 individuals captured representing 59 taxa, distributed in 46 genera and 18 families. Qualitatively, the Boumerdes region is the richest with 648 individuals; it is followed by that of Algiers then Tissemssilt with respectively 191 and 181. In most of the stations, the dominant family in terms of individuals is that of Apidae whose the rate exceeds 60%. The honey bee Apis mellifera intermissa has a remarkable relative abundance varying between 50% and 89%.

    Varroa destructor (Acari: Parasitiformes:Varroidae) a dangerous parasite of honey bees (Hymenoptera: Apidae)
    (Association for Advancement of Entomology, 2020) Adjlane, Noureddine; Jamal Haddad, Nizar
    The honeybee is an essential element of environmental balance in the world, particularly for its role in the pollination of many plant species. It also has other interests such as the production of honey, propolis, royal jelly and wax. Among several diseases on honey bees, the most dangerous is varroosis and threaten different species of honeybee population. Varroosis is caused by an external parasitic mite, Varroa destructor which parasites both bees and brood. It causes enormous damage to the colony and is a gateway to other viral and bacterial diseases. Information on the influence of this disease on colonies, symptoms and pathogenic actions, reproduction, development cycle and treatment methods viz chemical, natural, biological and biotechnical against Varroa are discussed.
