Abstract
Abstract The present study evaluated the abundance of tended and non-tended Dalbulus DeLong (Hemiptera: Cicadellidae) sp. leafhoppers and their parasitoids. A field study was conducted in the gamagrass Tripsacum dactyloides (L.) L. (Poaceae) habitat, where the mutualistic association between the leafhopper Dalbulus quinquenotatus DeLong & Nault (Hemiptera: Cicadellidae) and its tending ant Brachymyrmex obscurior (Forel) (Hymenoptera: Formicidae) occurs. Yellow sticky card traps were used to determine the abundance of Dalbulus leafhoppers and their parasitoids in this habitat. The results showed that D. quinquenotatus was the most abundant leafhopper, whereas Dalbulus gelbus DeLong and the corn leafhopper Dalbulus maidis (DeLong) (both Hemiptera: Cicadellidae), both non-tended species, were least abundant. Three egg parasitoid wasp species were identified: Anagrus naulti Triapitsyn & Moya-Raygoza (Hymenoptera: Mymaridae), which was the most abundant of the trapped parasitoids, and Paracentrobia Howard sp., and Pseudoligosita Girault sp. (both Hymenoptera: Trichogrammatidae). The parasitoids that inhabit the wild Tripsacum habitat are important to conserve due to their potential as biological control agents against corn leafhopper pests.
