Bee Viruses: Ecology, Pathogenicity, and Impacts
Annual Review of Entomology ( IF 15.0 ) Pub Date : 2019-01-10 00:00:00 , DOI: 10.1146/annurev-ento-011118-111942

Bees—including solitary, social, wild, and managed species—are key pollinators of flowering plant species, including nearly three-quarters of global food crops. Their ecological importance, coupled with increased annual losses of managed honey bees and declines in populations of key wild species, has focused attention on the factors that adversely affect bee health, including viral pathogens. Genomic approaches have dramatically expanded understanding of the diversity of viruses that infect bees, the complexity of their transmission routes—including intergenus transmission—and the diversity of strategies bees have evolved to combat virus infections, with RNA-mediated responses playing a prominent role. Moreover, the impacts of viruses on their hosts are exacerbated by the other major stressors bee populations face, including parasites, poor nutrition, and exposure to chemicals. Unraveling the complex relationships between viruses and their bee hosts will lead to improved understanding of viral ecology and management strategies that support better bee health.

蜜蜂病毒:生态,致病性及其影响

蜜蜂(包括孤独,社交,野生和受管理的物种)是开花植物物种的主要授粉媒介,包括近四分之三的全球粮食作物。它们在生态上的重要性,加上每年管理蜜蜂的损失增加以及主要野生物种数量的减少,使人们集中注意了对蜜蜂健康产生不利影响的因素,包括病毒病原体。基因组学方法极大地扩展了人们对感染蜜蜂的病毒的多样性,其传播途径的复杂性(包括属间传播)的理解,以及为应对病毒感染而发展的蜜蜂策略的多样性,其中RNA介导的反应起着重要作用。此外,蜜蜂种群面临的其他主要压力源(包括寄生虫)加剧了病毒对其宿主的影响,营养不良,并接触化学物质。弄清病毒与其蜜蜂宿主之间的复杂关系,将有助于人们更好地理解病毒生态学和支持更好蜜蜂健康的管理策略。
