Bees may soon get an ally in their fight against bacterial disease — one of the most serious threats the pollinators face — in the form of an edible vaccine. That’s the promise held out by researchers in Finland, who say they’ve made the first-ever vaccine for insects, aimed at helping struggling honeybee populations.
The scientists are targeting one of bees’ most deadly enemies: American foulbrood, or AFB, an infectious disease that devastates hives and can spread at a calamitous rate. Often introduced by nurse bees, the disease works by bacteria feeding on larvae — and then generating more spores, to spread further.
The idea of a potential new weapon to fight AFB has generated excitement in the beekeeping community, along with some skepticism about the claim of a vaccine — which remains in the testing phase. The news comes three years after the same researchers were hailed in Entomology Today as discovering the “key to bee vaccination.”
