Maize plants with similar numbers of Dalbulus maidis (DeLong & Wolcott) and Dalbulus elimatus (Ball) (Hemiptera: Cicadellidae) eggs were exposed to egg parasitoids in seasonal and perennial maize habitats. Both leafhopper species were parasitized by Paracentrobia tapajosae Viggiani (Hymenoptera: Trichogrammatidae), Anagrus breviphragma Soyka (Hymenoptera: Mymaridae), Aphelinoidea semifuscipennis Girault (Hymenoptera: Trichogrammatidae), and Pseudoligosita longifrangiata (Viggiani) (Hymenoptera: Trichogrammatidae). All parasitoids that attacked D. elimatus eggs are reported for the first time. Both leafhopper species showed similar number of parasitized eggs and similar percentages of parasitism. The parasitoids reached the adult stage. The levels of parasitism varied among the 2 habitats; a higher level of parasitism was observed in the perennial maize habitat compared with the seasonal maize habitat. Plantas de maiz con similar numero de huevos de D . maidis y D. elimatus fueron expuestos a los parasitoides. Ambas especies de chicharritas fueron parasitadas por Paracentrobia tapajosae Viggiani (Hymenoptera: Trichogrammatidae), Anagrus breviphragma Soyka (Hymenoptera: Mymaridae), Aphelinoidea semifuscipennis (Hymenoptera: Trichogrammatidae) y Pseudoligosita longifrangiata (Viggiani) (Hymenoptera: Trichogrammatidae). Todas las especies de parasitoides que atacan a los huevos de D. elimatus son reportadas por primera vez. Ademas, en ambas especies de chicharritas se encontro un numero similar de huevos parasitados y porcentaje de parasitismo, y los parasitoides encontrados llegaron a su estado adulto. La tasa total de parasitismo depende del tipo de habitat; en el habitat donde se cultiva maiz todo el ano, una alta tasa de parasitismo fue encontrada, mientras que en el habitat con maiz estacional, la tasa de parasitismo fue baja.
