Honey bee [Apis mellifera L. (Hymenoptera: Apidae)] genetic diversity may be the key to responding to novel health challenges faced by this important pollinator. In this study, we first compared colonies of four honey bee races, A. m. anatoliaca, A. m. carnica, A. m. caucasica, and A. m. syriaca from Turkey, with respect to honey storage, bee population size, and defenses against varroa. The mite Varroa destructor Anderson & Trueman (Acari: Varroidae) is an important pest of honey bee colonies. There are genetic correlates with two main defenses of bees against this parasite: hygienic behavior, or removing infested brood, and grooming, which involves shaking and swiping off mites and biting them. In the second part of this study, we examined the relationship of these two types of defenses, hygiene and grooming, and their correlation with infestation rates in 32 genetically diverse colonies in a 'common garden' apiary. Mite biting was found to be negatively correlated with mite infestation levels


Honey Bee Diversity Is Swayed by Migratory Beekeeping and Trade Despite Conservation Practices: Genetic Evidence for the Impact of Anthropogenic Factors on Population Structure
Kükrer, Mert; Kence, Aykut (2021-04-15)
The intense admixture of honey bee (Apis mellifera L.) populations at a global scale is mostly attributed to the widespread migratory beekeeping practices and replacement of queens and colonies with non-native races or hybrids of different subspecies. These practices are also common in Anatolia and Thrace, but their influence on the genetic make-up of the five native subspecies of honey bees has not been explored. Here, we present an analysis of 30 microsatellite markers from honey bees from six different r...
Genetic diversity of honey bee (Apis mellifera L.: Hymenoptera: Apidae) populations in Turkey revealed by RAPD markers
TUNCA, RAHŞAN İVGİN; Kence, Meral (2011-12-05)
The honeybee, Apis mellifera L. is an ecologically and economically important insect species. Recent honey bee losses causing decline of bee diversity is found alarming for the pollination of both wild plant biodiversity and crop production. Therefore, determination of genetic diversity of honey bee populations is essential and will provide a valuable resource for conservation purposes. Twenty Random Amplified Polymorphic DNA (RAPD) primers were used to assess the genetic diversity in 720 worker bees collec...

Genetic variation of honey bee populations from 9 different locations of Bulgaria was studied using 4 enzymic systems (MDH, ME, EST and ALP) corresponding to 4 genetic loci and PCR-RFLP's analysis of 16s rDNA, COI, and ND5 gene segments of mtDNA. Allozyme analysis revealed that all loci were polymorphic in almost all studied populations. The observed heterozygosity was found to range from 0.146 to 0.258, and Nei's genetic distance between 0.006 and 0.057 among the populations. Bulgarian honey bees are clust...
Behavioral and molecular impact of a stress factor, acaricide perizin on honey bees (apis mellifera) of Turkey
Arslan, Okan Can; Adalı, Orhan; Department of Biology (2020-9)
The effects of acaricide Perizin (coumaphos as the active ingredient) which is used against parasitic mite, Varroa destructor, on three native honey bee subspecies; Apis mellifera caucasica, A. m. carnica and A. m. syriaca. in terms of behavioral, molecular, and genetic aspects were investigated. After acute sub-lethal exposure to various doses of coumaphos, the worker bees of control and treatment groups were subjected to activity monitoring tests for evaluation of locomotor activity, electric shock ...
Differential diagnosis of the honey bee trypanosomatids Crithidia mellificae and Lotmaria passim

Trypanosomatids infecting honey bees have been poorly studied with molecular methods until recently. After the description of Crithidia mellificae (Langridge and McGhee, 1967) it took about forty years until molecular data for honey bee trypanosomatids became available and were used to identify and describe a new trypanosomatid species from honey bees, Lotmaria passim (Evans and Schwarz, 2014). However, an easy method to distinguish them without sequencing is not yet available. Research on the related bumbl...
