To know the diversity of these bees in this area of the country. The populations of bees from the orchids of Darién National Park in Panama were studied for five consecutive years (2013-2017), carrying out collections with chemical attractants. Results: It was found throughout the study that these populations decreased in terms of abundance and species richness. The variations found could be dueto environmental factors and the disposition of resources that these bees use. It is suggested to carry out more studies to better understand this panorama.
