Journal of Applied Entomology, Volume 150, Issue 7, Page 900-913, August 2026.ABSTRACT Within the subfamily Heliothinae, the genus Helicoverpa comprises several highly destructive agricultural pests, including H. armigera, H. assulta, H. punctigera and H. zea. These species cause significant global crop losses due to their wide host range, long‐distance migratory behaviour, and potential for interspecific hybridization.
