Bioecological and behavioral genetic aspects involved in the conservation of the stingless bee Melipona subnitida Ducke (Apidae, Meliponini) and the use of molecular tools in studies of diversity

The stingless bee Melipona subnitida is now present almost everywhere in the Brazilian Northeastern, as a consequence of its good adaptability to the semiarid and economic and ecological potential offered by the honey production and pollination of commercial crops under confined conditions. Nevertheless, it is an endangered species due to environmental degradation processes, among which are: deforestation, indiscriminate use of pesticides and honey extraction. Such interference tends to isolate populations of Jandaíra causing a decrease in genetic variability, and therefore a reduction in the adaptive capacity of the species. However, advanced Molecular Biology techniques have been used allowing such populations to be assessed for their degree of genetic variability. Molecular markers such as microsatellite DNA are widely applied to genetic diversity studies. However, due to the high costs required for their development, several studies have been focused on the use of microsatellites transferred from closely related taxa with much success in studies on the genetic characterization of species and their populations. Therefore, this review aimed to evaluate the most relevant ecological and behavioral aspects in order to assist the population genetic studies of the stingless bee M. subnitida.
