Descripción de los estados inmaduros de Delphacodes haywardi y notas acerca de su comportamiento en condiciones de laboratorio (Homoptera: Delphacidae)

Delphacodes haywardi Muir is one of the most widely distributed delphacids in crops within the wet Pampean region in Argentina; however, up to day, its biology is poorIy known. The anatomy of all preimaginal stages, life span, and reproductive behavior were studied under controlled conditions in ind...
