ABSTRACT / SAŽETAK:
Honey bees are crucial to ecosystems and human health as pollinators and producers of health- promoting products. However, honey bee colony mortality is rising globally due to parasites, pesticides, habitat loss, poor nutrition, and climate change, affecting the environment, economy, and human welfare. This paper presents the first 2D in vivo EPR imaging experiment on a honey bee, showing the redox status of their intestines. By monitoring spatio-temporal changes in the EPR signal of redox-active spin-probes, we can gain vital information on bee pathologies and the effectiveness of treatments. Using various spin-probes can further reveal pH levels and oxygen concentrations in bee tissues, allowing non-invasive assessments of bee physiology. This approach offers promising ways to safeguard pollinators, understand their biology, and promote their well- being and ecological balance.
