The Project aim is application nanofiber-based technologies for testion optimal elimination ways of invasive hornet Vespa velutina, significantly endangering population honeybee Apis mellifera. Nanofiber will be prepared from highly adhesive polymers to be functionalized with selected bioactive substances suitable for elimination or monitoring of this invasive species. An ultralight nanofiber-based transport system will be prepared and optimized for a specific transport of bioactive substances to the nest. Transport will be tested and verified on wasps. Simultaneously, fluorescence or sonic markers and non-linear agent imaging technique with encapsulated in nanofibers aerated liposomes will be applied for hornet monitoring.
