Determination of Anatolian Honeybee Biodiversity by Wing Characters

Abstract

In this study, we report that there were five different subspecies and three different ecotypes defined so far in Türkiye, which has a rich biodiversity in terms of honeybee subspecies. However, recently, it has been thought that the current biodiversity is in danger of extinction due to the commercial queen bee supply and the migratory beekeeping activities from a single source. This study uses the morphometric method to reveal the current status of honeybee biodiversity in Türkiye. For this purpose, a total of 3186 worker bees were studied by samplings from 19 different provinces to represent the honeybee races and ecotypes distributed in Türkiye. We made wing preparations and established 19 landmarks on the right forewings using the BAB BsPro200 program. The program automatically obtained the wing’s metrics’ angle, length, and index values via these 19 landmarks. We used Discriminant function analysis to determine intragroup and intergroup variations by taking the colony averages from data obtained from 31 morphological characters. Given the canonical discriminant function analysis and UPGMA dendrogram, Zonguldak, Düzce, Sakarya, Artvin, Ardahan, and Trabzon constituted a group, and Edirne, Kilis, Van, and Isparta formed a separate group. Hakkari, Kahramanmaraş, and Ordu provinces formed a separate line together. On the other hand, the group centers of Kars and Kırklareli, two different ends of Türkiye, overlapped and formed a close line with Isparta. As a result, this study revealed that, although the protection measures taken at the local level effectively protected the honeybee biodiversity, these measures are insufficient.
