First record of the major termite pest species, Reticulitermes flavipes (Isoptera: Rhinotermitidae), in Argentina.

Reticulitermes flavipes is the most invasive species in its genus and is responsible for causing significant damage to human structures in areas where it has been introduced. Although it has already become established in Chile and Uruguay, it had not previously been reported in Argentina. In this study, we report the first detection of this species in Buenos Aires, the capital of Argentina. The colony was already producing alates, and species identification was confirmed through both morphology and mitochondrial gene 16S rRNA analysis. Our results, while not conclusive, suggest that this introduction was independent from the one that occurred in Chile and Uruguay, and potentially originated from the United States. The detection of R. flavipes in Argentina is significant because it highlights the potential for this species to establish itself in new regions and underscores the need for future research on and control of R. flavipes in this country.
