Resumen:
Abstract ‒ The objective of this work was to identify, by molecular analysis,the species of the genus Helicoverpa in corn, soybean, and lucerne Bt andnon‑Bt crops, in central Argentina. A total of 1,343 carterpillars were analyzedby PCR-RFLP. Helicoverpa zea was the only species detected on non-Bt andon most Bt corn hybrids. The species H. gelotopoeon predominated on non‑Btsoybean and on lucerne, and H. zea larvae occurred in low proportion. Btsoybean did not show Helicoverpa spp. infestations. The exotic H. armigerawas not found, though adult moths of this species were light-trapped in acomplementary sampling.
