Bumblebees enlisted in fight against crop disease as scientists pioneer phage delivery system

Researchers at the University of Warwick have developed a method for using bumblebees to deliver bacteriophages—viruses that target harmful bacteria—to cherry blossoms, reducing disease-causing bacterial populations and decreasing reliance on pesticides. By coating bees with phage powder as they leave the hive, the insects transfer these natural treatments to flowers during pollination. The approach, initially tested on cherry canker, has shown high delivery rates and effectiveness, with potential for broader application to other crops. The method aims to offer growers an environmentally friendly, practical alternative for managing bacterial crop diseases.
