摘要

饮食可以对生物体的健康和适应性产生一系列直接和间接的影响,从而影响宿主-病原体相互作用的结果。土地利用的变化可能影响食物的数量和质量,对重要的自然和农业传粉媒介施加了觅食压力。饮食相关应激可加剧原有的病原体感染负面影响。在蛋白质和许多微量营养素方面,花粉占其营养摄入的大部分,花粉可以通过改变免疫、感染以及个体和群体健康的各个方面来影响蜜蜂的健康。我们研究了成虫花粉消耗、花粉类型和花粉多样性如何影响小黄蜂的生存和感染微孢子虫病原体小孢子虫的结果。实验中幼虫暴露在小菌落中,新出的成年工蜂被给予三种主要的单花、多花或无花粉饮食中的一种。评估了工蜂的大小、花粉消耗、成虫羽化后8天的感染、存活率以及死亡时细胞外微孢子虫孢子的存在。花粉饮食处理,特别是缺乏花粉,和感染单独降低了存活率,但我们没有看到花粉、花粉类型或花粉饮食多样性对感染结果的影响。后者表明,感染结果可能已经确定,在不同的饮食之前。尽管在我们的研究中,花粉饮食并没有改变感染结果,但它强调了病原体感染和花粉可用性对大黄蜂的健康都很重要,这些因素可能在大黄蜂发育的不同阶段、群体水平或不同饮食制度下相互作用。

Investigating the influence of diet diversity on infection outcomes in a bumble bee (Bombus impatiens) and microsporidian (Nosema bombi) host-pathogen system
Diet can have an array of both direct and indirect effects on an organism’s health and fitness, which can influence the outcomes of host-pathogen interactions. Land use changes, which could impact diet quantity and quality, have imposed foraging stress on important natural and agricultural pollinators. Diet related stress could exacerbate existing negative impacts of pathogen infection. Accounting for most of its nutritional intake in terms of protein and many micronutrients, pollen can influence bee health through changes in immunity, infection, and various aspects of individual and colony fitness. We investigate how adult pollen consumption, pollen type, and pollen diversity influence bumble bee Bombus impatiens survival and infection outcomes for a microsporidian pathogen Nosema (Vairimorpha) bombi. Experimental pathogen exposures of larvae occurred in microcolonies and newly emerged adult workers were given one of three predominantly monofloral, polyfloral, or no pollen diets. Workers were assessed for size, pollen consumption, infection 8-days following adult-eclosion, survival, and the presence of extracellular microsporidian spores at death. Pollen diet treatment, specifically absence of pollen, and infection independently reduced survival, but we saw no effects of pollen, pollen type, or pollen diet diversity on infection outcomes. The latter suggests infection outcomes were likely already set, prior to differential diets. Although infection outcomes were not altered by pollen diet in our study, it highlights both pathogen infection and pollen availability as important for bumble bee health, and these factors may interact at different stages of bumble bee development, at the colony level, or under different dietary regimes.
