    Caractérisation biologique et comportementale des populations d’abeilles locales en Algérie
    (Université M'Hamed Bougara Boumerdès : Faculté des Sciences, 2025) Haider, Yamina; Adjlane, Nourdine(Directeur de thèse)
    Cette étude approfondie sur l'apiculture en Algérie a révélé des dynamiques clés entre les pratiques apicoles, le comportement hygiénique des colonies et la santé des abeilles Apis mellifera intermissa face aux infections pathogènes. L'analyse des données de 200 apiculteurs a montré une prédominance de l'apiculture stationnaire, limitant les rendements en raison de la dépendance aux ressources florales locales. Les résultats indiquent que 66,5 % des apiculteurs signalent un faible rendement en miel, ce qui, combiné à une diminution continue de la production sur les dix dernières années, reflète les défis du secteur, exacerbés par le changement climatique et des pratiques de gestion inadéquates. Les tests statistiques, y compris l'ANOVA, ont révélé des différences significatives (p < 0.05) entre les colonies en ce qui concerne les taux de retrait du couvain mort, indiquant une variabilité importante du comportement hygiénique en fonction des saisons. L'analyse de la correspondance (ACP) a permis de visualiser les relations entre les différentes colonies et leur performance hygiénique, mettant en évidence certaines colonies, comme la Colonie 4, qui affichent un comportement hygiénique supérieur avec des taux de retrait atteignant jusqu'à 98 % en 48 heures. L'examen des corrélations entre les charges virales et les caractéristiques morphologiques des ailes a révélé des associations intéressantes. Bien qu'aucune corrélation significative (p > 0.05) n'ait été observée entre la morphologie des ailes et les niveaux d'infection par Nosema, des corrélations modérées à fortes ont été trouvées entre la charge virale de DWV-B et les spores de Nosema, suggérant que l'infection par Nosema pourrait aggraver les charges virales, ce qui mérite une attention particulière dans la gestion de la santé des colonies. En somme, cette étude fournit des bases solides pour des stratégies durables en apiculture algérienne. En investissant dans l'éducation des apiculteurs, l'amélioration des pratiques de gestion et l'adoption de technologies modernes, le secteur peut renforcer la résilience de ses colonies face aux menaces environnementales et sanitaires. Ces approches sont essentielles pour la prospérité économique et la préservation de la biodiversité en Algérie

    Environmental Impacts and Behavioral Adaptations of Honeybees in Algeria: A Review of Apis mellifera intermissa and Apis mellifera sahariensis Characteristics
    (Multidisciplinary Digital Publishing Institute (MDPI), 2025) Haider, Yamina; Adjlane, Noureddine; Haddad, Nizar
    Honeybees are vital for pollination and the overall health of ecosystems. Since the 18th century, the intricate biology of honeybees has been a subject of scientific inquiry. Understanding their biological and behavioral characteristics is essential for effective beekeeping, honey production, and ecosystem sustainability. This review examines the environmental impact and management practices on the health of local honeybees in Algeria, focusing on Apis mellifera intermissa and Apis mellifera sahariensis. We summarize research findings on genetic diversity, morphometric traits, behavioral characteristics, and adaptation of local honeybees. Additionally, we discuss the threats posed by abiotic and biotic stressors and highlight the importance of conservation and sustainable management. The reviewed studies indicate that environmental factors significantly influence the behavioral characteristics and adaptation of local honeybees. Notably, the hygienic behavior of A. m. intermissa contributes to their resistance against diseases and the Varroa destructor mite. Further research in these areas is important for enhancing our understanding of honeybee health and population dynamics in Algeria, thereby informing strategies for sustainable beekeeping practices

    Results of the nationale survery on algerian beekeebing (breeding practices, health situation)
    (2024) Haider, Yamina; Adjlane, Noureddine; Haddad, Nizar
    The honey bee plays a crucial role in maintaining plant biodiversity and environmental equilibrium, making beekeeping a vital activity in Algeria. However, the proliferation of Varroa ectoparasitic mites, causing varroasis, poses a significant threat to beekeeping in the region. This study, conducted between March and July 2022, aimed to comprehensively characterize the state of beekeeping in Algeria and identify its primary challenges. The survey was disseminated via email to beekeeping associations and individual beekeepers, with responses from 100 participants subjected to analysis, most of the respondents 97%, are men. 66% of the respondents practice sedentary and 34% transhumance. The findings shed light on the impediments to beekeeping development in recent years, including factors such as drought, elevated mortality rates, and the prevalence of bee pathologies. Notably, a significant portion of beekeepers refrains from conducting mortality analyses. The survey also revealed a substantial decline in honey production compared to previous years. However, positive aspects emerged, such as the presence of beekeepers employing sound beekeeping practices, including frame renewal, colony protection against adverse weather conditions, and the practice of transhumance. Furthermore, periodic varroasis screening in bee colonies was observed as a promising practice. Most beekeepers 98% use annual treatments for varroa mites in light of these findings, it is imperative for beekeeping associations to actively engage and take measures to organize and enhance the beekeeping sector, thereby addressing the current challenges.

    Sustainable beekeeping in algeria: exploring practices, challenges, and local honeybee traits for natural resource management
    (2024) Haider, Yamina; Adjlane, Noureddine; Martin, Hernande Raquel; Jamal Haddad, Nizar; Khemmouli, Abdelmounaim
    Honeybees are crucial pollinators, playing a vital role in maintaining plant biodiversity and promoting a healthy natural environment. They serve as bioindicators, reflecting the state of our ecosystems. Beekeeping in Algeria faces significant challenges, particularly the devastating effects of the Varroa mite, an ectoparasite harming bee colonies. This study aimed at understanding the resilience of Mediterranean bee subspecies in the context of climate change. Conducted in 2021, a survey targeted Algerian beekeeping associations and individual beekeepers. The goal was to characterize beekeeping practices, identify key challenges, and evaluate their impact on natural resources and sustainable development. The survey reached beekeepers in 19 Algerian provinces, with a total of 200 responses analyzed. The results highlight constraints hindering beekeeping development: drought, high bee mortality, and the presence of bee diseases. These findings suggest that beekeepers who select colonies with strong overwintering and drought resistance capabilities can potentially improve honey production. The COVID-19 pandemic further impacted honey production, leading to lower yields in recent years. However, positive aspects were also identified, including beekeepers implementing good practices (queen replacement, apiary selection, transhumance) and routine Varroa mite monitoring. Strengthening the role of beekeeping associations in the field is crucial to support the sector's organization and improve its current situation, ultimately contributing to sustainable management of natural resources in Algeria.
