In a pollen study, pollens were collected directly from the flowers by means of pollen traps installed at the entrances of honey bee colonies at 6 different stations. Pollen grains were analysed by Erdtman method, microscopic slides being prepared from them. By comparing the pollen grains collected by honeybees, with those collected directly from the flowers, the plants tripped by honey bees were identified and their specific characteristics described by reference to pollen characteristic tables (Pickard, 1984). Results indicated that collected pollens from Khansar region belonged to Papilionaceae family (16.6% of totoal species), Compositae family (16.6%), Labiatae family (13.33%), Umbelliferae family (10%), Caryophylaceae family (6.66%) along with other families (36.69%). In Chadegan region the pollens belonged to Compositae family (21.12% of totoal species), Papilionaceae family (15.5%), Labiata family (15.5%), Umbelliferae family (6.06%), and other families (41.44%). In Boeen and Miandasht the pollens belonged to Papilionaceae family (30.3% of total species), Labiatae family (18.18%), Compositae family (9.09%), Umbelliferae family (6.06%), along with other families (36.37%). In Agchea, Zameh and Sheshjavan regions, the pollens belonged to Papilionaceae family (21. 95% of total species), Compositae family (21.45%), Labiatae family (14.63%), Umbelliferae family (4.87%), and other families (42.73%). It can be concluded that flowers of Papilionaceae, Compositae, Labiatae, Umbelliferae and Caryophylaceae are the most attractive plant families to honey bees in these regions. The more extensive use of honey bees from the pollen of these plants could be due to higher attractiveness of the flowers and presence of more nutritive materials in the pollen and nectar.
