The 49th Apimondia International Apicultural Congress and Expo – the world\u2019s largest forum focusing on the scientific, economic, and environmental aspects of beekeeping – was held in Copenhagen between September 23\u201327, 2025. The event brought together more than 8,000 participants from 124 countries, including beekeepers, researchers, industry experts, and decision-makers, to share the latest knowledge shaping the future of the field.<\/p>

Our university was represented at this prestigious event by three researchers from the Department of Physiology and Biochemistry, Biochemistry Unit.<\/p>

Dr M\u00e1t\u00e9 Mackei<\/strong>, Assistant Professor, delivered the opening lecture in the conference\u2019s pesticide session. His presentation focused on investigating the effects of tebuconazole<\/em>, an agricultural fungicide, on the redox system in the flight muscles of honeybees.\"\"<\/a><\/p>

The results showed that tebuconazole treatment weakened the glutathione system but increased the antioxidant capacity of the flight muscles, while hydrogen peroxide and malondialdehyde levels decreased.<\/p>

These findings differ significantly from the research group\u2019s earlier observations, where tebuconazole caused severe oxidative damage in the bee brain. This suggests that different tissues exhibit varying sensitivity and adaptability to fungicide exposure, with the flight muscles showing efficient stress adaptation – unlike the central nervous system.<\/p>

\"\"<\/a>Fanni S\u00e1ra Huber, PhD student<\/strong>, presented her latest research results in the form of a poster, focusing on the changes in the fatty acid profile of the honeybee central nervous system under acetamiprid<\/em> exposure.<\/p>

The aim of the study was to determine how this widely used neonicotinoid insecticide affects the fatty acid composition of the bee nervous system, and through it, its function and integrity.<\/p>

According to the results, acetamiprid treatment caused detectable alterations in the fatty acid profile, which may influence membrane structure and neuronal metabolism.<\/p>

The study provides new insights into the neurotoxic mechanisms of neonicotinoids and contributes to a better understanding of the biochemical responses of bees to neurotoxic stress.<\/p>

Dr Evelin K\u00e1m\u00e1n-T\u00f3th<\/strong>, Assistant Professor, also presented her research in poster form, focusing on the expression changes of genes encoding various heat shock proteins (HSP)<\/em> and antimicrobial peptides (AMP)<\/em> in honeybees.<\/p>

The aim of her study was to evaluate the effects of potential cytoprotective compounds, such as curcumin<\/em> and quercetin<\/em>, which may help honeybees tolerate abiotic and biotic stress factors by influencing the expression of these genes.<\/p>

The results showed that curcumin enhanced the expression of heat shock protein genes, while quercetin had a rather inhibitory effect.<\/p>

The study provides new data on the function of genes responsible for HSP and AMP production in honeybees and explores the potential applicability of curcumin and quercetin in improving bee stress tolerance.<\/p>
