Abstract: We examined age-related biochemical and histological changes in the fat bodies and hemolymph of Osmia rufa males and females. We analysed solitary bees during diapause, in October and in April; as well as the flying insects following diapause, in May and June. The trophocyte sizes, as well as the numbers of lipid droplets were the greatest at the beginning of diapause. Subsequently, they decreased along with age. Triglyceride and glucose concentrations systematically decreased in fat body cells but increased i… Show more

“…The reason for the failure of the supply to reflect sex differences in demand for K, Na and Mn can only be speculated and might be either inadequate floral composition or weaker negative effects imposed on bee fitness by K, Na and Mn scarcity in larval food than by P, Zn and Cu scarcity. The sex-related differences in the biochemistry and chemical physiology of O. bicornis were reported previously (Strachecka et al, 2017). Further studies are needed to determine whether this mechanism occurs in various bee populations.…”

“…Większość białek krążących w hemolimfie pszczół jest syntetyzowana w ciele tłuszczowym, będącym tkanką analogiczną do wątroby i ciała tłuszczowego ssaków. Tkanki te odgrywają rolę w magazynowaniu oraz metabolizmie wysokoenergetycznych cząsteczek, detoksykacji, odpowiadają za magnetorecepcję i odpowiedź immunologiczną (28,64,121).…”

“…This time corresponds to a post-diapause quiescence (February-April), during which different metabolic rates are observed depending on tissue (generally high of fat body and low activity of biochemical compounds of haemolymph) Strachecka at al., 2017). During post-diapause in O. rufa, the protein concentrations rapidly changes with a decrease in fat body and increase in haemolymph and ovary (Wasielewski et al, 2011a;Strachecka et al, 2017). The application of higher temperature at the end of diapause and post-diapause may cause bees to emerge.…”
