abstract comparing with the numerous studies carried out in other countries, information on apoidea superfamily in iran is scare. during a faunistic survey of pollinator bees associated with alfalfa fields in mashhad and chenaran regions in 2010, numerous specimens of apoidea superfamily were collected and identified. among the identified species, anthidium diadema (latreille, 1809) is record f...

dashte-mashhad reservoir provides the water supply needed for irrigating 120 acres of agricultural lands and also the soft water for people living in mashhad, chenaran, golbahar and a number of villages in the region. the deep wells of the region have been using the water stored in this reservoir since 1350 in a rate which exceeds that of water being imported to it, hence the decrement of the w...
