“…In a previous study, similar results were obtained in the averages of the emergence weight of the queens reared from 1-day old larvae (Ozmen Ozbakır, 2021). The live weight of the queens varied between 171-223 mg in the queens obtained from commercial queen rearing enterprises (Arslan et al, 2021). The results of the current study were found to be lower than the average weights at the emergence of Italian queens (Faccini et al, 2021) and Caucasian queens (Kahya et al, 2008).…”

“…The number of ovarioles was similar to the values reported by Kahya et al (2008), Jackson et al (2011), Gregorc & Smodis Skerl (2015), and Walsh et al (2021) but higher than those reported by Faccini et al (2021). In the current study, the spermathecal diameter of the queens was similar to the values reported in many studies (Akyol et al 2008;Kahya et al, 2008;Arslan et al, 2021) but was lower than those reported by Faccini et al (2021).…”

This study was carried out to determine the crucial external and internal morphological characteristics for evaluating queens in three rearing periods (May, June, and July). Data of 65 queens reared from the local honeybees of the Sanliurfa (Apis mellifera L.) and Anatolian (Apis mellifera anatoliaca) honeybee colonies were used. Discriminant and principal component analyses (PCA) were done for thirty-one external and internal morphological characteristics of queens. The highest weight of the queen at emergence was determined in May for the Sanliurfa queens and in June for the Anatolian queens. The averages in ovary weight and spermathecae diameter of queens were found to be non-significant according to groups and periods. The number of ovarioles of the queens was different according to rearing period. Using the left basitarsus width variable, the Sanliurfa and Anatolian queens were classified correctly to their pre-assigned groups using discriminant analysis (73.8%). According to the result of PCA applied to all variables of queens, nine components explained 81.68% of the total variation. The seven variables in the first principal component were the left basitarsus length, the right hindleg length, the left hindleg length, the right basitarsus length, the left tibial length, the right tibial length, and the left basitarsus width. The forewing and the hindwing characteristics were included in the second principal component, and the number of ovarioles was included in the third principal component. The study shows that genotypes can be discriminated using the hindleg variables, in particular, as well as the internal and external morphological parameters of the queens.

“…For this reason, the most important member of a honey bee colony is the queen [5,6], and queen quality is a critical factor for successful beekeeping [7]. In beekeeping, it is a very important advantage to start with the use of quality breeders and qualified queens for economical beekeeping [8]. The characteristics that will be transferred to future generations through queen bees are of great importance in terms of colony behavior and productivity [9,10].…”

“…On the other hand, some researchers divided the queen bees into 3 groups according to their body weight: heavy (200 mg and above), medium (between 190-200 mg), and light (190 mg and below), and accepted the queens with 200 mg or more as high quality [24,25]. Many researchers agree that spermatheca capacity increases due to the decrease in larval age in queen rearing [8,25,26]. A queen's productivity and longevity depend on the queen's ability to store spermatozoa and the size of the spermatheca [27].…”

The Mediterranean region in Turkey is considered highly suitable for commercial queen bee rearing due to its temperate climate characteristics. Therefore, in the research, the queens to be examined in terms of quality criteria were obtained from commercial queen bee enterprises in Antalya, Mersin, Adana, and Hatay provinces in the Mediterranean region. In April-May, 5 queen bees from each of the 36 enterprises rearing queens were included in the study. Characteristics such as queen weight, spermatheca volume and diameter, and spermatozoa stored in the spermatheca are considered quality criteria, and the factors affecting them were evaluated on a total of 180 queens. Queens taken from the enterprises were divided into three groups according to their weight; light (172.56±1.75 mg), moderate (193.70±0.62 mg), and heavy (214.13±0.95 mg). The average spermatheca diameters in the light, medium, and heavy groups were 0.982±0.006 mm, 1.053±0.002 mm, and 1.215±0.008 mm, respectively. According to the average results obtained regarding the quality criteria in the study, it was determined that 60.55% of the queens evaluated in the study (the heavy group) were at standard quality levels. On the other hand, in the light and medium groups, it was observed that all values were below the quality standard values. These results show that while evaluating the quality criteria in queen bee breeding enterprises, selection can be made according to the weight of the queen bees.

“…The number of spermatozoa in spermatheca is crucial for the longevity and reproductive success of the queen. The number of spermatozoa in the spermatheca is one of the most common quality indicators of the queen (Kahya et al, 2008;Hatjina et al, 2014;Delaney et al, 2010;Arslan et al, 2021). The naturally mated queens have an average of 4-6 million spermatozoa in their spermatheca (Woyke, 1962(Woyke, , 1983.…”

This study aimed to determine whether the addition of diluent to fresh semen before injection affects the number of spermatozoa entering the spermatheca of the instrumentally inseminated queens. The queens reared by the grafting method were introduced into mating nucs one day before adult emergence. When 7-day old, the queens were allocated into four groups for the following instrumental insemination treatments. The queens in group 1 and group 3 were inseminated with 4 µl and 8 µl fresh semen, respectively (FS - 4 µl and FS - 8 µl). In group 2, the queens were inseminated with 4 µl fresh semen diluted 1-fold with NaCl solution (DS - 8 µl). In group 4, the queens were inseminated with 8 µl fresh semen diluted 1-fold with NaCl solution (DS - 16 µl). Each queen was dissected after the onset of oviposition for counting the number of spermatozoa in the spermatheca. There was not a significant difference in spermatozoa number between queens inseminated with 4 µl FS (2.57 million) and 8 µl DS (2.68 million). The queens inseminated with 16 µl DS (3.51 million) had fewer spermatozoa than the queens inseminated with 8 µl FS (4.46 million). The queens inseminated with 16 µl DS had more spermatozoa (3.51 million) than the queens inseminated with 4 µl FS (2.57 million, and 8 µl DS (2.68 million). The results revealed that the addition of 1-fold diluent to 4 µl fresh semen did not alter the number of spermatozoa. In contrast, adding 1-fold diluent to 8 µl fresh semen adversely affected the number of spermatozoa entering the spermatheca.
