Abstract
AbstractHoney bees play a pivotal role in shaping ecosystems and sustaining human health as both pollinators and producers of health‐promoting products. However, honey bee colony mortality is on the rise globally, driven by various factors, including parasites, pesticides, habitat loss, poor nutrition, and climate change. This has far‐reaching consequences for the environment, economy, and human welfare. While efforts to address these issues are underway, the current progress in electron paramagnetic resonance (EPR) instrumentation affords using the immense potential of this magnetic resonance technique to study small samples such as honey bees. This paper presents the pioneering 2D in vivo EPR imaging experiment on a honey bee, revealing the ongoing redox‐status of bees’ intestines. This way, by monitoring the spatio‐temporal changes of the redox‐active spin‐probes’ EPR signal, it is possible to gain access to valuable information on the course of ongoing bees’ pathologies and the prospect of following‐up on the efficiency of applied therapies. Employing a selection of diverse spin‐probes could further reveal pH levels and oxygen concentrations in bee tissues, allowing a noninvasive assessment of bee physiology. This approach offers promising strategies for safeguarding pollinators and understanding their biology, fostering their well‐being and ecological harmony.
