The aim this study was to analyze effect on predators dispersers. present conducted in a 30ha area secondary forest Southeastern Atlantic Brazil. This divided into two transects, which four points were marked with 30m distance from each other. Each sampling point contained total 30 artificial belong six different treatment groups, five per group. group randomly placed ground that checked every seven days. For fruit, 5mL essence (vanilla or pineapple) placed, no used control Artificial made green red nontoxic modeling clay, as well essences pineapple). A 960 fruits used. Predated equaled 26.9% (258 units), red/pine- apple had highest (81.9%), followed by red/vanilla (46.3%), while green/control not predated. Throughout experiment, bitten pecked 58.3% 41.7%, respectively. No significant differences recorded (x2=7.57, df=5, p=0.182) between fruit. important attracting dispersers, explains high red/ vanilla red/pineapple, absence predated Regarding potential disperser, there statistically difference As result, it should be taken consideration zoochory (mammalochory ornithochory) is most dis- persal; therefore, concluded birds more attracted mammals odor.
