The study of plant-insect interactions and how cultural groups perceive and manage them constitutes one of the interests of ethnoentomology. This work describes the association between host plants and longhorn beetles (Order: Coleoptera; Family: Cerambycidae), an important food among the Guaraní peoples of the province of Misiones, Argentina. Different management methods of host tree species are analyzed in order to promote the rearing of larvae for edible use. We also discuss a story about the mythical origin of cerambicids relayed by the Ava Chiripa Guaraní community. We reflect on the importance of the local worldview in the maintenance of ancestral practices, such as the cultural tasks involved in slash-and-burn agriculture and the intimate knowledge of biological relationships between the cerambycids and their woody host plants.

寄主植物协会与具有食物价值的长角甲虫：瓜拉尼人作为文化身份保持者的传统知识

研究植物与昆虫的相互作用以及文化群体如何感知和管理它们构成了民族昆虫学的兴趣之一。这项工作描述了寄主植物和长角甲虫（目：鞘翅目；科：天牛科）之间的关联，这是阿根廷米西奥内斯省瓜拉尼人的一种重要食物。分析了不同寄主树种的管理方法，以促进食用幼虫的饲养。我们还讨论了由 Ava Chiripa Guaraní 社区传播的关于 cerambicids 神话起源的故事。我们反思当地世界观在维持祖先习俗中的重要性，例如刀耕火种农业中涉及的文化任务以及对天牛与其木本寄主植物之间生物学关系的深入了解。
