【 摘 要 】

The goal of this work was to study the distribution of lepidopteran, coleopteran, and hymenopteran herbivores and their natural enemies within the canopy ofCaryocar brasiliense(Caryocaraceae) trees in the Brazilian cerrado. We observed thirteen rare, two common, and one constant species of herbivores insects; and three rare, eight common, and one constant species of natural enemies onC. brasiliense. The diversity, number of individuals and species of herbivores, and their natural enemies were similar among the cardinal orientation of thebranches of the host tree. However, the number of fruits bored by herbivores was smaller on the south side of the trees. Scraped fruits and Lepidoptera leaf mines were more numerous on the west side of the trees. In the case of natural enemies, ants and predator bugs presented highest abundance on the leaves in the eastern and northern sides of the trees, respectively. We argue that this differential distribution of natural enemies negatively influenced the defoliation and number of leaf mines. We also suggest that the speed and direction of wind may affect the distribution of insect herbivores on the different sides of the trees, with higher populations prevailing on the wind safe sites of the trees.
