Item Effect of miticides amitraz and fluvalinate on reproduction and productivity of honey bee apis mellifera(Bursa Uludağ Üniversitesi, 2021-03-30) Ilyasov, Rustem A.; Lim, Sooho; Lee, Myeong Lyeol; Kwon, Hyung Wook; Nikolenko, Alexey G.Varroa destructor is a well-known ectoparasite of the honey bee Apis mellifera. Amitraz and fluvalinate are highly effective miticides used against V. destructor infestation in colonies of honey bee A. mellifera. Though honey bees more resistant to miticides, there are side effects of these chemicals on the reproduction, olfaction, and honey production of honey bees. We showed a negative impact of miticides amitraz and fluvalinate on honey production and reproduction of honey bee colonies. Also, we assumed the reduction of olfaction of honey bees by fluvalinate due to changes of expression of olfactory related neuropeptide genes short neuropeptide F sNPF, tachykinin TK, short neuropeptide F receptor sNPFR. The external treatment of honey bee colonies by miticides amitraz and fluvalinate along with a positive effect of pest control harms reproductivity, honey productivity, and, probably, can reduce learning and memory, gustation and olfaction of honey bees. When used for a short time and with care, miticides can be less harmful to honey bees. Breeding varroa-resistant honey bees allow to reduce the use of miticides and produce organic honey. Therefore, the further development of beekeeping should be in the direction of selection for disease and Varroa resistance and adaptation to the environment.Item Phenetic variation in honey bee (apis mellifera) population of the Toratau Geopark, the Republic of Bashkortostan(Bursa Uludağ Üniversitesi, 2023-05-11) Sagitov, Salavat T.; Ilyasov, Rustem A.; Sattarov, Vener N.; Abdrakhimova, Yuliya R.; Danilenko, Valery N.; Gazizova, Nailya R.; Sattarova, Amilya V.; Boguslavsky, Dmitry V.A phenetic analysis of the honey bee population of the Toratau Geopark (Russia) was performed. Over 1,000 worker and drone bee samples were collected from 250 colonies in 59 apiaries on the territory of the Toratau Geopark (Gafuriysky, Ishimbaysky, Meleuzovsky, and Sterlitamaksky districts of the Republic of Bashkortostan). Six phenes in worker bees and four phenes in drone bees were recognized. The phenes E, 1R, 2R, and 3R in workers and Is, I, and O-gray in drones were predominant in the honey bee population of the Toratau Geopark, which were associated with subspecies of the Clineage. These phenes can be used as indicators of introgressive hybridization in the local dark European honey bee population. The phenes allow for quick evaluation of certain honey bee colonies hybridization states.
