    Colony characteristics and the performance of Caucasian (Apis mellifera caucasica) and Mugla (Apis mellifera anatoliaca) bees and their reciprocal crosses
    (INT BEE RESEARCH ASSOC, 2001) Akyol, E; Kaftanoglu, O
    There are seven climatic regions and several honey bee (Apis mellifera) races and ecotypes adapted to these regions in Turkey. The most common and popular bee races are the Caucasian bees (A. m. caucasica), native to northeastern Anatolia, and the Mugla bees (A. m. anatoliaca), native to south-western Anatolia. Both races have desirable characteristics and they are widely used by beekeepers all over the country. We tested the colony characteristics of Caucasian (C x C) and Mugla (M x M) bees and their crosses (C X M) and (M x C) under migratory beekeeping conditions to combine the desirable characteristics of both races and increase honey yield. All the experimental queens were instrumentally inseminated and introduced into five-frame colonies in the spring of 1996. Colonies headed by Mugla queens produced significantly more honey than Caucasians, and M x C crosses produced significantly more honey than other genotypes. Brood production was significantly higher in M X M and M x C colonies. The C x C were the most gentle and the M x C crosses were the most aggressive genotypes. The study shows that honey yield and brood production can be increased significantly with selection and controlled mating.

    The discrimination of Artvin and Ardahan honeybees (Apis mellifera L.) using morphological characteristics
    (Scientific Technical Research Council Turkey, 2002) Güler, A; Akyol, E; Gökçe, M; Kaftanoglu, O
    This study was conducted to determine the morphological characteristics and to identify the honeybee (Apis mellifera L.) genotypes husbanded in the Artvin and Ardahan cities of the northeastern Anatolia Region. A total of 84 worker bee experimental samples were collected from 8 apiaries; in different locations. From each sample 20 workers were used and 19 morphological characteristics were measured biometrically. Samples used were collected from 3 regions of Ardahan (Ardahan-Center, Posof-Yenikoy and Posof-Sungulu) and from 5 different regions of Artvin province (Hamurlu, Kaikci, Borcka-Camili, Savsat-Kocabey and Muratli). As a result of discrimination analysis there was found to be no variation between bees from deffirent areas in T-4 and cubital vein length a on the front wing. Though 7 discriminant functions were analysed, the first three functions accounted for 84.1% of the total variation. The 24 samples taken from Artvin Borcka-Camili and 10 samples from Ardahan-Center and 10 samples from Ardahan Posof-Yenikoy were completely classified into their real groups. Artvin Borcka-Camili, Ardahan-Center, Posof-Yenikoy samples were distinguished from other groups and formed a distinct group. Whereas, in the Hamurlu, Kaikci, Savsat-Kocabey and Muratli populations the samples overlapped.
