ABSTRACT Feeding bees carbohydrates, as a substitute for nectar, has become essential in modern beekeeping. We compared the effects of 65% sucrose (SS) and invert sugar (IS) syrups on survival enzyme activity caged honey bees. Specifically, we analyzed glycosidase head midgut composition sucrose‐based (SH) sugar‐based (IH) “honey” stored by collected from comb. Glycosidase was similar contrast to where it higher IS fed bees, which appeared be residual yeast β‐fructofuranosidase activity. Fructose glucose ratio SH were 60.84/39.16 presence some other sugars detected, while IH 48.49/51.51, almost exactly same start (48.57/51.43). It been demonstrated that Zymogram detected α‐amylase band SH, IH, suggest do not add amylase into IS. In no crystallization occurred IH. SS densities 1.23 1.24 g/mL, respectively, increasing 1.35 g/mL 1.28 after processing. This suggests humidity restricted cleansing flight make harder remove excess water leading increased hindgut weight, correlates with mortality third week IS‐fed group fourth SS‐fed group.

Chalkbrood is the manifestation of fungal disease caused by Ascosphaera apis, which affects broods developing honeybees, particularly in Apis mellifera colonies. Recently, Metschnikowia pulcherrima has been proposed as a biocontrol agent winemaking and for management major postharvest soil-borne plant pathogenic fungi. In this study, antagonistic activity three M. strains against fifteen A. apis strains, isolated from contaminated hives mellifera, was evaluated, with specific focus on potential antifungal volatile organic compounds (VOCs). The study revealed that effective related to various mechanisms including competition nutrients, secretion pulcherriminic acid, biosynthesis VOCs. We also found each strain produced unique combination VOCs, strain-dependent varied depending yeast-mold combination. addition, preliminary analyses showed temperature 30 °C higher amount glucose (40 g/L) growing medium promote growth apis. These results could be useful designing new strategies chalkbrood honeybee
