Abstract

 

An exotic species of ambrosia beetle (Coleoptera: Curculionidae: Scolytinae) of Asian origin has been detected recently in Argentina. Euwallacea interjectus (Blandford) has been collected infesting cultivated poplars in the Paraná Delta region. Identification was based on morphology and on DNA sequences of the COI gene. This finding adds to the increasing number of recent introductions of exotic ambrosia beetles into South America.

 


 

 

 

Sumario

 

Recientemente se detectó por primera vez en Argentina una especie exótica de escarabajo de Ambrosía (Coleoptera: Curculionidae: Scolytinae) de origen asiático. Euwallacea interjectus (Blandford) fue colectada afectando cultivos de álamo en la región del Delta del Río Paraná. Su identificación se basó en la morfología y en las secuencias de ADN del gen COI. Este hallazgo se suma al número cada vez mayor de introducciones recientes de escarabajos de Ambrosía exóticos en Sudamérica.
