Abstract The current study is one of more steps for further research in Alexandria (Western Egypt). The area of study had no beekeeping activity, but one swarm was present in a gap between two walls. An area far from any human interferences except agricultural services was chosen to study the following points: 1) The species composition of non Apis bees in Al Hawaria region and their interaction with the floral resources of the region. 2) Is the presence of honeybee having an impact on solitary bee species abundance, a case study of four crops in Al Hawaria region? This research’s point of view is considered as a preliminary study in Western Egypt to evaluate the effect of honeybee presence on solitary bee species abundance. 1. General Survey of collected solitary bees during the flowering period of some uncultivated and cultivated plants in the two years 2021-2022 in Alexandria at Al Hawaria Region: A total of 820 specimens of solitary bees were collected during the flowering period of the following plants uncultivated (Centaurea glomerata, Centaurea alexandrina, Lycium shawi, Enarthrocarpus lyratus, Diplotaxis harra, Mesembryanthemum crystallinum, Papaver rhoeas, Tamarix aphylla, Malva parviflora) and cultivated (Ocimum basilicum, Sesamum indicum, Trifolium alexandrinum). The collected bees were represented by five families (Apidae, Megachilidae, Halictidae, Colletidae and Andrenidae). The family Melittidae was absent in this study. The collected bees were representing 24 genera (9 of Apidae, 7 of Megachilidae, 5 of Halictidae, 2 of Colletidae and one of Andrenidae). The total number of species found in the region was 51 species (25 of Apidae, 17 of Megachilidae, 3 species of Halictidae, one species of Colletidae and 5 species of Andrenidae). Summary 82 Two species were recorded for the first time in Egypt of the genus Hoplitis: (Hoplitis (Hoplitis) zonalis Perez,1895) recorded in April 2021 on Enarthrocarpus lyratus (Brassicaceae), & (Hoplitis (Pentadentosmia) moricei (Friese,1899) recorded in June 2021 on Ocimum basilicum (Labiatae) as described by Andreas Müller. |
