Résumé
In this research the pollination by bees specialists and generalists of the six species of cactus and sampled structure interaction semidesieto the state of Queretaro it was observed. The frequency of performing a bee visits to observe the pattern of specialization was used and to know the structure of the community bee/cactus abundance, richness and diversity of Shannon were used. A study of interaction networks was conducted to understand if the network bee/cactus is generalist or specialist and identify bees are specialist and what could be the possible pollinators.

Habitat deterioration may be contributing to the presence of exotic bees and the low species richness found at this site. In could also suggest that the cactus/bee interaction is limited to a small number of bees that share the resources provided by cactus species during the flowring period. How generalised the species involved in this study should be further evaluated to determine the importance of other plant species in the structruring of theplant/pollinatornewtworkatthissite,andhighlighttheimportanceofmaintainingnative vegetation for pollonator health.
