Arthropods associated with a Bombus pauloensis (Hymenoptera: Apidae: Bombini) nest in the Sabana of Bogotá (Colombia)

Abstract

Bumblebees are important natural pollinators due to their services to wild and cultivated plants. They commonly nest in cavities in the ground where they are exposed to numerous organisms or interact with them. One Bombus pauloensis nest in the Sabana of Bogotá (Colombia) was transferred to an artificial nest and relocated close to a honeybee apiary after the original nest was threatened by an intentional fire. The objective was to preserve the colony and simultaneously identify arthropods associated with a bumblebee nest as this is poorly studied in Colombia. Samples of the organisms found in the bumblebees’ nest were collected for taxonomic identification. Several commensal, scavenger and parasitic organisms were found, including Antherophagus sp. (Coleoptera: Crytophagidae), wireworm beetles (Coleoptera: Elateride), Fannia canicularis (Diptera: Fanniidae), and mites of genera Parasitellus and Pneumolaelaps. This is the first report of other organisms besides Antherophagus from a B. pauloensis nest in Colombia.
