Résumé
Bee visitors of fruit trees blossoms and surrounding wild flowers were recorded. A transect was determined in Ebbin village in Ajlun (32°22" N, 35°49" E), from which bees and flowering plants were collected once a week during the year 2003. A total of 1777 specimens were collected and found to represent five families : Apidae, Megachilidae, Halictidae, Andrenidae and Colletidae. Most of the specimens were identified up to the species level and few specimens were identified up to the genus level. The following 53 bee species are recorded for the first time in Jordan : Sphecodes albilabris, Sphecodes monilicornis, Anthophora albigena , Anthophora aestivalis, Anthophora plumipes, Bombus terrestris, Ceratina chalybea, Ceratina cucurbitina, Eucera nigrescens, Nomada succincta, Nomada nesiotica, Nomada fabriciana, Nomada brausiana, Tetralonia salicariae, Tetralonia dentata, Xylocopa violacea, Anthidium undulatum, Chelostoma diodon, Heriades syriaca, Hoplitis crenulata, Hoplitis pallicornis, Lithurgus tibialis, Megachile melanopyga, Megachile hungarica, Megachile parietina, Megachile pilidens, Osmia melanogaster, Osmia rufa, Pseudoanthidium palaestanicum, Stelis nasuta, Trachusa pubscens, Trachusa verhoeffi, Halictus sexcinctus, Halictus quadricinctus, Halictus pollinosus, Lasioglossum calceatum, Lasioglossum marginatum, Lasioglossum pallens, Lasioglossum pauxillum, Andrena alfkenelloides, Andrena elmaria, Andrena flavipes, Andrena garrula, Andrena humilis, Andrena iliaca, Andrena impasta, Andrena melittoides, Andrena krausielle, Andrerna spectabilis, Andrena thorascica, Andrena tscheki, Colletes caskanus, Hylaeus angustatus. Both Apidae and Megachilidae were the largest in terms of diversity, while Halictidae showed the highest abundance. The most ten anthophilous bee species were determined, topped with Halictus quadricinctus. Most melittophilous plant families and species were determined and ranked. 75 plants visited by bees belonging to 25 families were recorded for the first time in Jordan as melittophilous plants. Five families showed the highest melittophily : Compositae, Papilionaceae, Boraginaceae, Liliaceae, Rosaceae, and Cruciferae. Most melittophilous species were Almond (Rosaceae) and Dittrichia viscosa (Compositae). However, the stone fruit trees (almond, plum, Apricot, and cherry) showed a high diversity in their floral visitors of bees. In general, bee species of the genus Anthophora (Apidae) and Andrena (Andrenidae) were found to be flower visitors of all stone fruit trees.
