    Andrena species (Hymenoptera : Apoidea : Andrenidae) from Western Algeria, with a preliminary assessment of their pollen preferences
    (Taylor & Francis, 2021) Dermane, Abdelkader; Bendifallah, Leila; Michez, Denis; Wood, Thomas J.
    Algeria, the largest country in Africa, has a species rich bee fauna because of its ecological conditions, climate and diversified flora. The present work represents a list of the genus Andrena Fabricius, 1775 in western Algeria. The survey, carried out during the period 2017–2019, has allowed identification of 56 species of Andrena in a total of 787 specimens (496 females, 291 males), with one species new for the fauna of Algeria, Andrena (Aenandrena) hystrix Schmiedeknecht, 1883. Preliminary pollen preferences of the most common species were analysed in Algeria for the first time, comprising seven polylectic and 12 oligolectic species. The current work provides a baseline for future studies on the diet of Andrena and is one of the first studies on the floral preferences of North African bees

    Bee fauna potential visitors of coriander flowers coriandrum sativum L. (Apiaceae) in the mitidja area (Algeria)
    (2013) Bendifallah, Leila; Louadi, Kamel; Doumandji, Salaheddin
    Coriander Coriandrum sativum L. (Apiaceae) is a year-round condiment and aromatic Mediterranean plant. It is cultivated in several countries in North Africa, in Europe, and Western Asia. In the El Harrach area of Algiers, the insect fauna visiting crop flowers includes Diptera (Syrphidae), Coleoptera, and Hymenoptera such as Chrysididae, Vespoidea, and Apoidea (Bees). The latter super-family comprises the majority of insect pollinators. Visiting bees belong to four families: Apidae, Andrenidae, Halictidae, and Colletidae. The main visitors are honeybees and six species of Andrenidae: Andrena flavipes, Andrena thoracica, Andrena lagopus, Andrena bimaculata, Andrena discors, and Andrena cinerea elliptica. The three species Andrena lagopus, Andrena bimaculata, and Andrena cinerea elliptica have 100% pollinating visits while Apis mellifera has only 63%. Andrena cinerea elliptica is the most frequent and the most abundant species

    Checklist, Diversity and Distribution Of Wild Bees (Hymenoptera: Apoidea; Anthophila) Across Tlemcen Mountains, In The North West Of Algeria
    (Jfas, 2021) Youssouf, Ouahab; Bendifallah, Leila
    Our study concerns the diversity and distribution of wild bees through three sites in the Tlemcen mountains. The present paper contains a checklist of 155 taxa with three new records for the Apoid fauna of Algeria. These are Andrena marginata Fabricius, 1776, Anthidium manicatum Dallatour, 1877 and Megachile latimanus Say, 1823. The index study and the statistical treatments applied to the results made it possible to highlight the composition of this fauna, its dependence on floral resources and its spatio-temporal distribution across the region. The results obtained reveal a high richness of Apoids in this region, the conservation of which is necessary in the future as this fauna plays a key role in the pollination of plants and their diversity within natural and agricultural ecosystems

    Diversity of Odonates (Odonata, Anisoptera & Zygoptera) in the Theniet El Had national Park-North West of Algeria
    (Tarbiat Modares University, 2023) Mairif, Mohamed; Bendifallah, Leila; Doumandji, Salah Eddine
    The aim of this study is to make an inventory of the fauna of the Odonata in Theniet El Had National Park, which helps managers to make appropriate decisions for the conservation of these species. The site is entirely forested (Cedrus and Quercus species) with numerous intra-forest natural environments (clearings, grasslands, rocky habitats, springs, pools and ponds, etc.), this mosaic of habitats harbours a remarkable wealth of fauna and flora. Our study focused on the natural and artificial temporary forest ponds, scattered throughout the park, which are of biological and ecological interest for a very wide range of insects, most notably the hemimetabola. These are characterised by a larval stage that is quite different from the adult stage in terms of habitat and lifestyle, namely odonates, where the larvae are aquatic whereas the adults have an aerial life. The inventory of odonates was carried out through monthly surveys of 8 water bodies (7 forest ponds and one hill reservoir) during one year, from March 2017 to February 2018. This preliminary inventory allowed us to inspect 240 individuals of odonates belonging to 18 species i.e. 11 genera and 5 families. The species recorded at the end of this study are the subject of a cartographic representation showing their distribution at the local scale (in the park) and at the national scale

    The taxonomic impediment : a shortage of taxonomists, not the lack of technical approaches
