Abstract: 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.
