Evidence of separate karyotype evolutionary pathway in Euglossa orchid bees by cytogenetic analyses Anais da ABC (AABC)
FERNANDES,ANDERSON; WERNECK,HUGO A.; POMPOLO,SILVIA G.; LOPES,DENILCE M..
Euglossini are solitary bees considered important pollinators of many orchid species. Information regarding chromosome organization is available for only a small number of species in this group. In the present work, the species Euglossa townsendi and E. carolina were analyzed by cytogenetic techniques to collect information that may aid the understanding of their evolution and chromosomal organization. The chromosome number found was n = 21 for males and 2n = 42 for females in the two species. The distribution and amount of heterochromatin regions differed in the two species analyzed, where they were classified as “high” or “low” heterochromatin content, similarly to what has already been performed in social bee species of the genus Melipona.
