Bombus brevivillus Franklin is a Neotropical Bombusspecies whose colonies are disappearing from most of its native range, and little is known about its biology and reproductive habits to help conservation or breeding efforts. Unlike Bombusspecies from temperate climates whose colonies perish every winter, there are suggestions of perennial colonies that Neotropical Bombusspecies can present. In this work, we investigated the development of two B. brevivilluscolonies (i.e., number of workers, gynes, males, new cocoons, and brood area) between August 2012 and March 2013. We realized that while one colony collapsed and died after the males’ and gynes’ production, and the reduction of numbers of adult workers, in the other, a new queen assumed the posture at this phase and reactivated the old nest. Despite the reduced number of colonies investigated, this study shows the possibility of nest reactivation in the studied species in queen supersedure events in resemblance to perennial colonies of eusocial bees like Apisspecies and stingless bees. Such behavior has never been directly described to B. brevivillusin previous studies and opens the possibility for further research in the existence and the extension of perennial colonies in Neotropical Bombusspecies due to its importance to the species conservation in the tropical environment. |
