The Giant Willow Aphid (Tuberolachnus salignus, GWA) is an invasive pest insect in New Zealand, which excretes honeydew. European honeybees collect this honeydew and make it into a type of honey that crystallizes in the comb, representing a significant loss to apiarists. This crystallization has been ascribed to high concentrations of oligosaccharides, particularly melezitose. In this research, the first carbohydrate profile of GWA honeydew honey, a sample of GWA honeydew honey was found to contain 37.8% total oligosaccharides of which 27.4% was melezitose, and 2.5% gluconic acid (higher than typical honeydew honeys); 41.2% monosaccharides (lower than typical honeydew honeys); and 0.054% salicylic acid (higher than previous estimates). Melezitose extracted from GWA honeydew honey was not significantly hydrolyzed in crude human-stomach and human-small-intestine simulations and may therefore meet the prebiotic criterion of human indigestibility.
巨型柳蚜（Tuberolachnus salignus，GWA）是新西兰的一种入侵性害虫，它会分泌蜜露。欧洲蜜蜂会收集这种蜜露，并将其制成一种在蜂巢中结晶的蜂蜜，这对养蜂人来说是一个重大损失。这种结晶归因于低聚糖，特别是棉子糖的高浓度。在这项研究中，首次对巨型柳蚜蜜露蜂蜜的碳水化合物图谱进行了分析，发现 GWA 蜜露蜂蜜样本中含有 37.8%的总低聚糖，其中 27.4%为棉子糖，2.5%为葡萄糖酸（高于典型的蜜露蜂蜜）；41.2%为单糖（低于典型的蜜露蜂蜜）；0.054%为水杨酸（高于之前的估计）。从 GWA 蜜露蜂蜜中提取的棉子糖在粗人胃和小肠模拟物中没有明显水解，因此可能符合人体不可消化的益生元标准。
