Pathogen spillover from managed honey bees to wild pollinators poses a significant threat. Thai Sacbrood Virus (TSBV) affects honeybee larvae, killing them and hindering colony growth, particularly endangering Asiatic honeybees (Apis cerana indica). The virus spreads through the movement of bee colonies for pollination and honey production. TSBV caused a major outbreak in South India in 1991-1992, wiping out about 90% of Asiatic honey bee colonies. The virus resurfaced in Telangana in 2021 and has also been reported in countries like China and Vietnam.
