Entomovectoring with Mojgan Rabiey at Warwick - bumblebees can carry bacteriophages to cherry flowers, allowing control of cherry canker on flowers (and thus fruit) - bees can find the flowers better than we can to distribute the phages.
I've never heard of it with phages before but seems an exciting and promising (and environmentally safer) route to part of canker management. Also means bees don't spread the pathogen as the phage "disinfects" them.
