    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.

    Study of the major factors threatening the survival of bee colonies Apis mellifera intermissa in Algeria
    (2011) Adjlane, Noureddine
    Bees, in addition to producing honey, pollinate fruit trees and other crops to flowers. Any threat to them, whether from , pesticides, diseases or parasites therefore have serious consequences not only for beekeeping, but also for agriculture in general. For several years, many beekeepers have reported deaths at their apiaries of honey bee Apis mellifera intermissa. At present, we lack hard data on the causes of these deaths in Algeria. In order to provide some answers to this problem, we conducted a field study among beekeepers in the Mid-northern Algeria. This study is supplemented by information from cooperative bee of the technical institute of livestock and veterinary services department at the Ministry of Agriculture and the regional laboratories of veterinary medicine. The analysis results showed bee diseases mainly represented by the varroa, bee poisoning by insecticide treatment, and the degradation of the ecosystem (decreasing flora honey) and climate change. All these factors threaten the native bee and negatively affect the production of honey.

    Presence and infestation rate of Senotainia tricuspis (Meigen) (Diptera, Sarcophagidae) on honey bees in the Mediterranean Region
    (Taylor and Francis Online, 2015) Jamal Haddad, Nizar; Adjlane, Noureddine; Loucif, Wahida; Shebl, Mohamed; Saba, Muna; Albaba, Imad; El-Obeid, any; Montasir, Sabah; Giusti, Matteo; Felicioli, Antonio
    Our investigations show that the S. tricuspis is found in four countries out of the seven sampled ones. This pest was recorded in Egypt, Jordan, Algeria, and Italy, Samples from Iraq, Lebanon and Palestine were negative for infestation. We confirmed the presence of S. tricuspis in the southern and western areas of the Mediterranean sea, and diagnosed its existence for the first time in Egypt, but the big variation in the infestation level comparing the northern countries of the sea to the southern countries, propose two hypotheses: the first one is that this parasite prefers the wet areas rather than dray ones. The second hypothesis is that Apis mellifera ligustica bees are more susceptible than the bees of the southern and eastern countries of the Mediterranean region. To confirm such hypotheses further investigations in the region need to be conducted by collecting bigger sample size from the region. We also propose that further DNA studies are needed in order to build a phylogenic table to understand the genetic diversity and population genetics of S. tricuspis in the region. A wide Mediterranean North -South collaboration in technology transfer, extension and awareness program will be very helpful for the beekeeper sector in this region.
