“…On average, the egg stage lasts for 7. 1 days at a constant temperature of 22°C, 4 days at 23°C, and 3 days at 28˚C (Tasei, 1973;Rust, Torchio, & Trostle, 1989;Giejdasz & Wilkaniec, 2002). It is worth noting, that in Tasei's (1973) study the egg stage was measured together with the larval stage until the first moulting of the larva.…”

“…The development of the red mason bee is similar to that of other spring species of the Osmia genus. The embryonic and larval development, which is divided into five growth stages, occurs in the spring, while the prepupal and pupal stages take place in the summer (Tasei, 1973;Rust, Torchio, & Trostle, 1989;Giejdasz & Wilkaniec, 2002). In the prepupal stage, the metabolic processes slow down.…”

A b s t r a c t The red mason bee (Osmia rufa L.) is a univoltine solitary species of the Osmia genus. This bee is reared on a commercial scale and used as a managed alternative pollinator. We intended that the results of our study would improve the management of this bee so as to synchronise their flying period with the blooming of crops. In the spring, we moved newly occupied nests of the red mason bee to a laboratory and placed them in incubators. Immature development was examined at three constant temperatures, 20˚C, 25˚C, and 30˚C. Selected nests were opened to monitor the subsequent developmental stages. The remaining bees were wintered in nests stored at cool temperature (4˚C). In April, we removed the insects from the nests and began incubation at 25˚C to establish the emergence time of adult individuals. To determine the survival rate of adult bees, we moved the emerged specimens to cages, where they were fed and kept until death. Temperature increase generally reduced immature development time. But this tendency was not observed in the prepupal stage. During ontogeny the highest mortality rate was observed in wintering adult insects at developmental temperatures of 25˚C and 30˚C. Bees developing at constant temperatures emerged faster during spring incubation in comparison to those developing in natural conditions. Constant developmental temperatures decreased the survival rate of females as post-emergence adult insects. The survival rate of males was lower at the developmental temperature of 30˚C.

“…Five larval stages were identified on the basis of both size and presence of the previous instar exuvia (Rust et al, 1989). Because of their small size, larvae belonging to the first, second, third and fourth instars were pooled before analysis (sample 1), while the fifth instar larvae were separated into the following three subgroups: pollen-eating V instar (sample 2), mature V instar (sample 3) and diapausing V instar (sample 4).…”

Expression profile of water-soluble proteinases during ontogenesis of Megachile rotundata: an electrophoretic investigation

et al. 2004

-Variations in proteinase activity pattern in larva, pupa and imago of the solitary bee Megachile rotundata are described. Extraction of insect homogenates under mild conditions was followed by the electrophoretic separation of the protein extract in polyacrylamide gels, precast with either gelatine or pollen protein extracts. In these conditions, twelve distinct proteinases were detectable in the pooled I-IV instar larvae, six in the pollen-eating V instar, two in the mature V instar, none in the diapausing V instar, none in the pupa, and two in the imago. Some of the detected proteinases were able to digest the protein mixture extracted from the pollen provisions. Some proteinases were insect specific since they were not detectable in pollen provisions extract. The enzymologic properties of the major proteolytic band suggest its serine-proteinase nature.solitary bee / Megachile rotundata / development / proteinase / zymography

“…The shortening of the day length in autumn coupled with the lowering of temperature is sufficient to induce adult diapause in many insects (De Wilde et al 1968;Rust et al 1989;Krafsur et al 1999;Herman and Tatar 2001), whereas in several Osmia species, it is dependent on temperature and independent of photoperiod (Bosch and Kemp 2000;Bosch et al 2010;Sgolastra et al 2010).…”

The potential role of adiponectin- and resistin-like peptides in the regulation of lipid levels in the hemolymph of over-wintering adult females of Osmia bicornis

et al. 2014

-The presence and potential role of adiponectin-and resistin-like peptides in mobilizing free lipids of hemolymph during over-wintering was studied in females of the European solitary red mason bee Osmia bicornis L. (Hymenoptera: Megachilidae). The levels of both peptides (as demonstrated both by RIA/ELISA and Western blots) were highest in fat body tissue homogenates during early pre-wintering (September) followed by a gradual and significant decline during wintering and post-wintering months (November-March). There was a gradual reduction of the lipid levels in hemolymph and adiponectin-like and resistin-like peptide content in fat body. Thus, the total lipid content in hemolymph and the adiponectin-like and resistin-like peptides in fat body homogenates was positively correlated. Our experiments also demonstrated that injections of various concentrations of fat body extracts as well as various doses of adiponectin and resistin increased the lipid levels in hemolymph in O. bicornis females at the three different periods of over-wintering time. In particular, injections of fat body extract and adiponectin resulted in the strongest mobilization of lipids especially in the first two periods of over-wintering: pre-wintering and wintering. Resistin also elicited an increase of lipid levels in hemolymph, but its effectiveness was lower compared to fat body extract and adiponectin. Taken together, our results strongly suggest the presence of adiponectin-like and resistin-like peptides in the fat body of O. bicornis and postulate a dynamic physiological role for these peptides during the process of over-wintering.adiponectin / diapause / free lipids / hemolymph / Osmia bicornis / over-wintering / resistin / solitary bee
