Title: AN ANT-MEMBRACID-PLANT INTERACTION IN A CERRADO AREA OF BRAZIL
Author: DANSA, CVD

Abstract: In the Cerrado of Itirapina, Brazil, 34% of the shrubs of Didymopanax vinosum (Araliaceae) were colonized by the honeydew-producing homopteran Aconophora teligera (Membracidae) which was found exclusively on this species of plant. Correlations were made between membracid density and ant frequency, as well as between these parameters and plant damage. We found that: (1) ant frequency was higher on branches with membracids and both were more frequently found near apical meristems; (2) herbivore damage was lower on apical meristems where the membracids concentrate than on ones where they are absent; (3) the presence of membracids on the plant was correlated with a reduction in the occurrence of other potential herbivores, especially on the branches housing membracids; (4) plants with more tillers tended to have a larger number of membracids. The data suggest that the presence of A. teligera and associated ants probably reduce herbivory on apical meristems of D. vinosum.
