Recently identified bee viruses and their impact on bee pollinators

Area of Science:

• Entomology
• Virology
• Ecology

Background:

• Bees are crucial agricultural and ecological pollinators.
• Significant annual losses in honey bee colonies and declines in wild bee populations are observed.
• These declines can affect food crop availability and native plant biodiversity.

Purpose of the Study:

• To highlight the importance of bees as pollinators.
• To underscore the potential impacts of pollinator decline on food security and ecosystems.
• To discuss the role of viral infections in pollinator health.

Main Methods:

• Utilizing next-generation sequencing technologies.
• Identifying novel bee-infecting viruses.
• Characterizing viral strains and pathogenicity.

Main Results:

• Picornarna-like RNA viruses are common bee pathogens.
• New viruses, including Lake Sinai viruses and Rhabdoviruses, have been identified through sequencing.
• Specific viral strains, like Deformed wing virus variants (DWV-A, DWV-B, DWV-C), and their pathogenicity have been characterized.

Conclusions:

• Viral infections are a significant threat to bee health.
• Advanced sequencing is crucial for identifying and understanding bee viruses.
• Understanding viral strains and their impact is essential for pollinator conservation efforts.
