The article "Host Plants of Spodoptera frugiperda (Lepidoptera: Noctuidae) in the Americas" by Débora G. Montezano, Alexandre Specht, Daniel Ricardo Sosa-Gómez, Vânia F. Roque-Specht, José Carlos Sousa-Silva, Silvana V. de Paula-Moraes, Julie A. Peterson, and Thomas Hunt provides a comprehensive review and update on the host plants of the fall armyworm, *Spodoptera frugiperda*. This pest, which is one of the most significant noctuid moths in the Americas, has recently become invasive in Africa. The study aims to compile and analyze existing literature and survey data to create the most detailed list of host plants for *S. frugiperda* to date. The authors conducted a literature review and surveys in Brazil, resulting in 353 records of larval host plants belonging to 76 plant families, primarily Poaceae (106 taxa), Asteraceae (31 taxa), and Fabaceae (31 taxa). The literature search yielded 274 bibliographic records, while 82 new records were identified through surveys. The new records significantly expand the known host plant range, which is crucial for understanding the pest's biology and developing effective Integrated Pest Management (IPM) strategies. The study highlights the polyphagous nature of *S. frugiperda*, its ability to feed on a wide variety of plants, including both crop and non-crop species. This polyphagy can lead to high crop damage and pest pressure, especially when larvae disperse to cultivated crops after consuming non-crop hosts. The comprehensive list of host plants, including non-crop species such as weeds, is essential for effective pest management, as it helps in identifying potential host plants within and around crop fields to prevent early instar development and reduce pest populations. The article also discusses the biological factors influencing the broad host plant range, such as female moth oviposition behavior and larval movement. The study emphasizes the importance of basic biological information, such as host plant lists, in developing effective pest management strategies.The article "Host Plants of Spodoptera frugiperda (Lepidoptera: Noctuidae) in the Americas" by Débora G.
