PRELIMINARY RESEARCHES REGARDING THE GENETIC AND MORPHOMETRIC CHARACTERIZATION OF HONEYBEES (A. MELLIFERA L.) FROM ROMANIA

Abstract

The international investigations regarding the honeybees’ diversity carried out until now have revealed a certain degree of genetic pollution in different countries from Europe, because of the import of more productive honeybees’ races or of some interracial honeybees’ hybrids. This fact might have a negative impact on the success adaptability of honeybees at the ecosystem. Although, the Romanian honeybees (Apis mellifera carpathica) are well adapted to the local conditions and express a good resistance to diseases, the introgression (genetic pollution) of different honeybees’ races could be an imminent event. So that, starting from 2007, by a cooperation between the Institute for Beekeeping Research and Development from Bucharest and the Institute of Genetics of the University of Bucharest, we have initiated different investigations in order to obtain a more accurate state of the Romanian honeybees’ diversity. We have performed specific molecular analyses, using mtDNA (the COI-COII test) extracted from 32 different honeybees samples collected from several regions from Romania. For a better and detailed characterization of the collected honeybee’s samples we have also carried out some morphometric measurements of their wings. Our data have shown that the Romanian population of honeybees is almost homogenous from the genetic and the morphometric points of views. These types of investigations represent a premiere for Romania.
