Abstract	Herbivorous insects in flower-buds of Caryocar brasiliense Camb. (Caryocaraceae): Comparison between two cerrado areas in Brasília, DF. Herbivorous insects are among the main representatives groups of the huge biodiversity found in neotropical areas. Even that, exists an accumulation of information on occurrence of caterpillars species (Lepidoptera) that feed on the leaves of host plants in the Cerrado. However, little it is known about herbivore insects in reproductive structures of these plants. The present work was divided in two chapters. The first one presents a first survey of herbivore insects associated to the inflorescences of Caryocar brasiliense in two areas of cerrado in the Distrito Federal, besides comparing the herbivore insects fauna observed, between the areas. The second chapter compares the temporal and spatial variations of the populations of herbivore insects obtained, and it also presents the correlations among these groups of insects. From June 2005 to November 2005, on the University of Brasilia's Experimental Farm (FAL) and unpreserved cerrado fragments found on the campus of Brasília's University (UnB), A hundred plants of C. brasiliense were sampled with a total of 293 examined inflorescences. No significant difference was found between the number of inflorescences and the adults emergence in both studied areas. It was obtained 12 species belonging to seven families of Lepidoptera, being two, Phidotricha erigens (Pyralidae) and one Gelechiidae species not identified, the main ones were responsible for the major attacks to the inflorescences, which impeding the flower and fruit development. They were the most abundant species, alternating the adults' dominance among the areas, being the species of more abundant Gelechiidae in FAL, and the species of Pyralidae at UnB. All the obtained hymenopterans are parasitoids, represented by 11 species belonging to six different families. Again two species were dominant, Cheloninae sp. and Rogadinae sp., and these were observed as parasitoids of Gelechiidae sp.39. In spite of FAL area
