Resumen

During the 2021/2022 soybean production season in Itapúa, Paraguay, the presence of Etiella zinckenella (Treitschke) caterpillars affecting soybean pods in the country was documented. The observations were made amidst a widespread drought that adversely affected soybean production. Caterpillars were collected from pods that exhibited signs of pest entry. Morphological characterization of the collected specimens matched the descriptions provided in taxonomic keys for E. zinckenella larvae. Molecular identification through DNA extraction and sequencing confirmed the identity of the pest as E. zinckenella, exhibiting a 96% similarity with known accessions of the species in the GenBank database. As a challenging pest to control, efforts should be directed towards evaluating the economic and damage thresholds caused by E. zinckenella, assessing resistance in soybean varieties used in Paraguay, and investigating the efficacy of biological and chemical insecticides. These findings can contribute to the development of integrated management strategies for effectively mitigating the impact of this pest on soybean production in Paraguay.
