Frankliniella panamensis Hood 1925 (Thysanoptera: Thripidae) is a thrips species of increasing interest as a potential pest of crops in Central and South America and as a contaminant in international trade, especially for ornamentals. We identify, collate, summarize, and critically analyze information from national, regional, and international sources, on the taxonomy, diagnostics, distribution, biology and ecology, pest status, and pest management of F. panamensis. Approximately 90 articles of relevance were identified. Most were locatable in either Google or Google Scholar, but electronic or hard copies were sometimes difficult to obtain. The taxonomic status of F. panamensis is established. After past issues, especially those that related to the distinction between F. panamensis and Frankliniella occidentalis, suitable morphological and molecular diagnostics for F. panamensis have been developed. F. panamensis has mostly been recorded from between 1400 and 3600 m asl in several Central and South American countries and especially in Colombia, Costa Rica, Ecuador, and Panama. Adults of F. panamensis have been recorded from flowers and leaves of many endemic and introduced plants, including weeds, in Central and South America, but details on the feeding and breeding hosts for this thrips species are rare. F. panamensis seems to be multivoltine and exhibits arrhenotoky. F. panamensis is clearly a transitory species in some protected crops but there is little evidence as to whether it maintains breeding populations under these conditions. F. panamensis is listed as a pest in several South American publications, but we found little published evidence of direct or indirect damage caused by the species to any cultivated or uncultivated plant species. Until the pest status of F. panamensis is clarified, this species will probably remain a quarantine issue in international trade in some countries. We identify knowledge gaps and priority areas for future research.
