研究了先进的社会性纸黄蜂（Polybia occidentalis）的营养物质的种类、获取速率、个体间转移和种群内运动。觅食工蜂（“觅食蜂”）将节肢动物猎物和营养液（“花蜜”）带到巢中，这些通常被转移到巢外外壳上的工蜂（“接受者”）。节肢动物的猎物被完整地带到巢中，在被喂给幼虫之前，会被一个或多个接受者麻醉；松弛的成虫会保留一部分血淋巴作为自己的营养。花蜜通常（通过成虫-成虫的传送带）从觅食者传递到蜂巢外壳上的接受者；一些花蜜是给幼虫的，所有吸收花蜜的成虫至少会保留一些作为自己的营养。西棘棘虫幼虫唾液中含有葡萄糖、蛋白质和游离氨基酸，营养价值高；唾液的营养成分与其他群居黄蜂类群的唾液非常相似。成年黄蜂会吸收幼虫的唾液，但很少有幼虫会通过营养轴（trophallaxis）传递给其配偶。在本研究中，幼鸟同类相食的现象并不常见。成年工蜂和雄蜂的中肠中含有胰凝乳蛋白酶和胰蛋白酶样酶，因此可能具有消化蛋白质的能力。中肠蛋白酶表现出与年龄相关的浓度变化。纸浆觅食者明显比接受者更小，重量更轻。
The kinds, rates of acquisition, inter-individual transfers, and intra-colonial movements of nutrients were ascertained for the advanced eusocial paper wasp Polybia occidentalis (Olivier). Foraging worker wasps (“foragers”) bring arthropod prey and nutritive liquids (“nectar”) to the nest, and these are usually transferred to nest workers (“receivers”) on the outer nest envelope. Arthropod prey items, which are brought intact to the nest, are malaxated by one or more receivers before being fed to larvae; malaxating adults retain a portion of the hemolymph for their own nourishment. Nectar is usually transferred (via adult-adult torphallaxis) from foragers to receivers on the nest envelope; some nectar is given to larvae, and all adults that imbibe it retain at least some for their own nourishment. Larval saliva of P. occidentalis contains glucose, protein, and free amino acids and so is highly nutritive; the nutrient content of the saliva closely resembles that of the saliva of other social wasp taxa. Adult wasps imbibe larval saliva, but very little is apparently transferred by those adults (via trophallaxis) to nestmates. Brood cannibalism was infrequent during this study. Adult worker and male wasps possess chymotrypsin-like and trypsin-like enzyme in their midguts and so are likely capable of protein digestion. The midgut proteases show an age-correlated variation in concentration. Pulp foragers are significantly smaller and lighter in weight than are receivers.
