Abstract Previous studies on various organisms have suggested that low doses of ethanol can stimulatory effects, while higher may lead to toxicity, a response known as hormesis. Low concentrations occur naturally in the environment, particularly fermenting fruits and flower nectar, where pollinators such honey bees encounter it. This study aimed investigate potential hormetic effects low-level consumption bees. Bees were divided into three groups: one provided with only sucrose solution, both 0.5% sucrose, 1% sucrose. The exposed these diets for 14 days, their performance was assessed through survivorship, flight endurance, body mass, lipid content, trehalose levels haemolymph. results showed no significant differences most parameters between groups.

While clear observed terms improved performance, elevated indicate adaptations protecting from ethanol-induced damage. provides insights how tolerate exposure highlights need further research ecological implications pollinators.

Honey bees (Apis mellifera) are one of the most crucial pollinators, providing vital ecosystem services. Their development and functioning depend on essential nutrients substances found in environment. While collecting nectar as a carbohydrate source, routinely encounter low doses ethanol from yeast fermentation. Yet, effects repeated exposure bees' survival physiology remain poorly understood. Here, we investigate impacts constant occasional consumption food spiked with 1% honey bee mortality alcohol dehydrogenase (ADH) activity. This concentration might be tentatively judged close to that natural conditions. We conducted an experiment which were exposed three types long-term diets: sugar solution (control group simulated conditions no access ethanol), every third day (that occasional, infrequent ethanol) daily (simulating constant, routine ethanol). The results revealed both increased bees, but only after several days. These rates rose frequency intake. ADH activity remained similar all groups. Our findings indicate carries harmful accumulate over time. Further research is needed pinpoint exact ingested
