草食性昆虫可以通过免疫反应来防御病原体，这种免疫反应受到寄主植物的营养质量和植物化学的影响。然而，目前还不清楚饮食的这些方面是如何相互作用来影响昆虫的免疫反应的，也不清楚摄入的叶面微生物起到了什么作用。我们检测了饲料蛋白质、植物化学和毛虫微生物群，以了解梅丽莎蓝蝴蝶Lycaedes Melissa免疫反应的变化。我们还通过测量L来询问这些因素是否具有寄主植物特异性的影响。在最近定居的外来寄主植物(紫花苜蓿)上饲养的紫花苜蓿与在祖先、本地寄主(加拿大黄芪)上的免疫反应相比，紫花苜蓿的免疫反应。萨瓦尔。然而，我们确实发现了植物化学多样性的负面直接影响，以及来自饲料的微生物多样性对毛虫的结构性免疫反应的负面直接影响。紫花苜蓿，以酚氧化酶活性衡量。叶蛋白并不直接影响免疫反应，但通过增加体重间接影响免疫反应。我们的结果强调了寄主食物对毛虫生理的重要影响，并提高了叶片微生物区系尽管快速通过肠道，但可以影响毛虫免疫反应的可能性。
Herbivorous insects can defend themselves against pathogens via an immune response, which is influenced by the nutritional quality and phytochemistry of the host plant. However, it is unclear how these aspects of diet interact to influence the insect immune response and what role is played by ingested foliar microbes. We examined dietary protein, phytochemistry, and the caterpillar microbiome to understand variation in immune response of the Melissa blue butterfly,Lycaeides melissa.We also asked if these factors have host plant-specific effects by measuringL. melissaimmune response when reared on a recently colonized exotic host plant (Medicago sativa) as compared to the immune response on an ancestral, native host (Astragalus canadensis).L. melissadid not experience immunological benefits directly related to consumption of the novel plantM. sativa. However, we did find negative, direct effects of phytochemical diversity and negative, direct effects of diet-derived microbial diversity on constitutive immune response for caterpillars fedM. sativa, as measured by phenoloxidase activity. Foliar protein did not directly influence the immune response, but did do so indirectly by increasing weight gain. Our results highlight the important effects of host diet on caterpillar physiology and raise the possibility that foliar microbiota, despite being rapidly passed through the gut, can affect the caterpillar immune response.
