Description:	Rice is essential to global food security, and its crops are challenged by the presence of Aeschynomene Fabaceae (jointvetch), whose control by herbicides generates environmental, health and resistance risks. Thus, this study aims to characterizing the assemblage of phytophagous insects associated with A. denticulata and A. indica during two rice harvests, and cooperates in identifying possible biocontrol agents and understanding the role these plants play as alternative hosts of insects that have agricultural pest status. A total of 300 plants were inspected where phytophagous entomofauna was collected. Faunal analysis was performed, including its abundance, constancy, dominance, frequency, richness, diversity, equitability, rarefaction and principal component analysis (PCA). Acanthoscelides atrocephalus, Morphospecie 6, Ceresa sp., Morphospecie 2 and Euschistus heros were predominant when collecting the two plants. For the first time, 15 species of insects associated with A. denticulata and 16 with A. indica were recorded. Among the insects found, species such as A. atrocephalus present in the seeds and Tyloderma sp. (observed in the roots) showed potential for future research in Integrated Weed Management as bioagents. The observed association between jointvetch and economic interest insects, such as E. heros, suggests that these weeds may favor the maintenance of these populations in the rice-growing area. These results contribute to the development of sustainable strategies in weed management for rice cultivation, and expand knowledge about ecological interactions of these species.
