Tritrophic interaction": first record of Colopterus truncatus (Coleoptera: nitidulidae) and its parasitoid Bruchophagus sp. on Inga marginata SEEDS

Inga marginata Willd., commonly known as inga-feijão, inga, inga-dedo, or inga-mirim, is a widely distributed species throughout Brazilian territory, virtually found across the entire country. Its occurrence is not limited to Brazil, extending to other countries in South and Central America. This plant exhibits remarkable ecological adaptability, in various habitats, although it is most commonly found in riparian forests. Ecologically, Inga marginata is a semi-deciduous, heliophilous, selective hygrophilous, and pioneer species. It is characteristic of the Atlantic and Amazon rainforests but can also be found in the semi-deciduous broadleaf forests of the Paraná basin. In natural environments, it is common to find it in secondary vegetation, especially in moist soils. Additionally, the plant is abundant in transitional areas, such as forest edges, riverbanks, and along roadsides. However, its presence in dense primary forests is more limited. An important aspect of Inga marginata is its ability to produce many viable seeds annually. This characteristic significantly contributes to its dispersal and colonization of new habitats. Considering its ecological importance and wide geographic distribution, this species has attracted scientific interest in various fields, including studies on its ecology, interactions with other species, and potential use in environmental restoration and agroforestry programs. In this sense, this article aims to present the first record of Colopterus truncatus (Coleoptera: Nitidulidae), an insect that preys on Inga marginata seeds, as well as its respective parasitoid Bruchophagus sp. This record contributes to understanding the ecology and biological interactions involving this plant species and its associated insects.
