Wild bees in agroecosystems with different management system

Abstract

Wild bees occupy a key position in the maintenance and conservation of natural ecosystems
and agroecosystems, since they offer great service to nature: pollination. However, in the agricultural
fields of the UACh, an inventory of these organisms has not been carried out, nor has
the way in which the implemented management systems affect the wild bee populations. For
this reason in this project it was proposed to identify under which management system the
greatest richness of wild bees is presented, which was estimated by placing color traps in five
areas of production of the university. We collected 160 specimens (five families Andrenidae,
Apidae, Halictidae, Oxaeidae and Sphecidae) located at 19 Morphospecies. It was found that
the richness of morphospecies is not statistically different between these areas; however it is
necessary to reinforce the samplings to make a more precise evaluation
