ABSTRACT:  Caatinga is a unique and exclusive biome in Brazil and, despite this, there are few studies that seek to understand the process of herbivory that occurs in plant species, even though this is an element of great importance about ecological relations. Considering the scarce information about the action of the edge effect on the herbivory of the plant species Ziziphus joazeiro Mart. (juazeiro) in Caatinga area, this study aimed to verify if there is influence of the edge effect on the herbivory in juazeiro, considering both the edge and the interior region of a forest fragment. The study was conducted in a Caatinga fragment in the municipality of Igaci-AL, with an experimental area divided into 20 linear transects of 10m², 10 transects in the edge region of the area and another 10 within the studied area. In each transect, 10 leaf limbs were randomly collected, separated in plastic bags and taken for analysis, where they were photographed and analyzed using the Image J software. The data obtained were transformed into √x + 1 and submitted to analysis of variance. The means compared by Tukey test at 5% probability using the SISVAR program. The herbivory rate was also calculated. A total of 34 individuals were found, 17 inside the fragment and 17 at the edge. Although in gross numbers there is a difference in the herbivory level between the edge and the interior, statistically there was no significance, presenting the same herbivory level in both regions. In addition, the herbivory rate averages in edge and inland conditions were not statistically significant either. Regarding the percentage of leaves with herbivory (herbivory rate), they were classified in category 1. Thus, it can be concluded that the edge effect did not influence the herbivory of the species in this Caatinga fragment. KEYWORDS: semiarid, plant-animal interaction, habitat fragmentation.
