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. Diffe...

... registered the cutting of several specific tree species in order to promote the rearing of edible longhorn or wood beetle larvae: yvyra ñechĩ [Balfourodendron riedelianum (Rutaceae)] ( Figure 2A); ...
Context 2
... general, adult individuals of longhorn beetles are known to the Guaraní as yvyra ñe kichiˈa or yvyra jaga'a, meaning "tree cutter" (yvyra refers to the tree or wood, kichi or jaga means to cut, and 'a to fall). Likewise, these insect larvae have a Guaraní zoonym, ycho akambe (ycho-aka-mbe) which translates as "flatheaded larvae" ( Figure 2B) referring to the flat shape of their mouthparts in the larval stage. ...

... Guaraní inhabitants in this study mention that all species of larvae belonging to this group are consumed, with a preference for those that develop large sizes. In this study Orthomegas jaspideus ( Figure 2C) and Enoplocereus armillatus ( Figure 2D) were identified. While walking through the jungle, they also register trees that have fallen, generally due to winds and storms, and then return to check for developing larvae and collect them in due time. ...

The Guaraní observe the presence of takuapi cane [Merostachys claussenii (Poaceae)] to define the site of a new cultivation area, as they consider the species a good indicator of the quality of soils for this purpose. ...

... perform the kokue, the Guaraní fell trees and subsequently dry and burn them. Once the burning has been carried out, the area is cleared and the soil is left free from obstacles for sowing ( Figure 2F). When there is abundant bamboo, the burning is fast and superficial which promotes, according to some Ava Chiripa interlocutors, a greater degree of larval infestation in the remaining trunks. ...

... The economy of settlers is associated with diversified family agriculture sustained in their plots with perennial and annual plantations, cattle raising, and livestock breeding (poultry, pigs and fish in ponds) intended for self-consumption and sale in regional markets. The Guarani people retain much of their traditional subsistence practices, such as slash-and-burn agriculture, harvesting, hunting and fishing for most of the year within large areas of the forest they currently inhabit (Araujo et al. 2021, Cebolla Badie 2013, Keller 2008. ...
Background: Human populations develop locally-based knowledge about the species used as firewood through the use of natural resources, and by experimenting with cultural guidelines and transmitting their experiencies. In the selection and use of firewood this knowledge is mainly based on the igneous properties of each species. This study was carried out in rural settlements and indigenous populations of the province of Misiones, Argentina. We surveyed combustion properties and local categories of firewood classification. We analyzed the most relevant characteristics of the firewood obtained from different species and the multiple applications assigned to it according to local criteria. We recorded the origin of the species used as fuel and their selection criteria, the vernacular nomenclature and the descriptor elements of the firewood qualities. Based on them we identified classification categories. Methods: The information was obtained through semi-structured interviews, free lists and participant observation. Results: Through Principal Component Analysis, we established groups of species associated with combustion properties or attributes and identified the emerging criteria that associate them. There were 21 species preferred, most of them native. Differences were observed in the frequency of firewood collection by the two groups, with more frequent activity among the indigenous. In both groups, wood usually comes from dry, medium to large individuals. They both select, use and prefer species whose main attributes as firewood are duration of the embers, intensity of the flames and low emission of smoke. Conclusions: The tudy of classification system provides key information and broadens knowledge of the semantic corpus involved in their perception and practices.
