Although their population explosions are cyclical, the return of the tucuras to Patagonia continues to generate concern due to the significant impact they cause on crops and grasslands. Alarms were first raised this year in the provinces of Río Negro, Chubut, and Santa Cruz, where since October an agricultural and livestock emergency has been in effect as declared by Senasa, particularly due to the variety Bufonacris claraziana, better known as the "tucura toad." Now, the fear has spread to Neuquén, where births of the variety Dichroplus maculipennis, or "spotted wings," have already been detected.
