These cages allowed free access to the ants. Formicidae com produtos naturais by: It was concluded that volatiles of seed elaiosomes were attractive to the ants, and also that composites of elaiosome have potential to be used in the confection of toxic baits.

In olfactometer, the ants were attracted by volatile of the seeds with elaiosome and by odor of commercial baits when air was offered as alternative source.

In this work t In both the study areas, the research was conducted in two habitats, secondary forest and old field, using seeds of M. Thus the aim of this last experiment was to answer the following questions: However, in these areas, the contribution given by the ants was also relatively important. Seed dispersal by ants myrmecochory is important for many species of plants.

After that, in the field, the attractiveness of baits made of elaiosome, elaiosome-grass and commercial baits were investigated. No Acamari trabalhou-se com sementes de M. This tool could be further used for understanding succession processes in environment recovery.

Peternelli, Ethel Fernandes de Oliveira. In the experiments wire cages 15 x 15 x 10 cm; 1. Part of the experiments was carried out in laboratory and part in the field. Initially the role of volatile produced by elaiosome of seeds of Mabea fisutlifera Euphorbiaceae in the attraction of ants Atta sexdens rubropilosa and Atta bisphaerica was investigated, with the use of olfactometry in laboratory.


A segunda parte dos trabalhos foi responder a seguinte pergunta: To compare the removal of cortadeirras by ants and vertebrates in the two areas forest and old fieldtwo parallel m transects were established in each area within the Formgias or ESGR. No segundo teste, sementes coladas foram oferecidas. George nos Estados Unidos. Peternelli, Ethel Fernandes de Oliveira Published: They effectively dispersed the seeds of S.

In the third and last part removal rates of seeds in two succession stage; old field with shrub regeneration and secondary forest, in tropical and temperate formitas were evaluated. Workers of this species collected more the combination of elaiosome-grass bait.

Ants respond to the external stimulations promoted by an appendage elaiosome rich in lipids, attached on to the seed, by carrying the seeds to their nests, where the appendage is removed and used as food.

Each species of ant treated the seeds in different ways. To determine which ants had interacted with the seeds, all the observed interactions between ant and seed were registered throughout a m transect.

The removal of elaiosome was made essentially by the minor workers inside the colony. In the field A.

In the second test, glued seeds were offered; in the third test, the seeds were allowed to be explored by the workers formigaz leaf-cutting ants with the presence of two invading species, Pheidole sp. Made available in DSpace on T Padilha, Marco Antonio Published: Doutorado em Entomologia Department: Seed dispersal Leaf-cutting ant Myrmecochory. Typical myrmecochorous seeds were relatively more collected than the diplochorous.



It was observed that, different species of ants interacted with the seeds of M. And test the following hypothesis: Formicidae em eucaliptais by: Interaction between ants and seeds, with emphasis in the leafcutting ants. The second part of the work was to answer the following questions: Two areas were chosen to conduct this last work: The cortadeirras of these invaders influenced the exploration, cut and transport time of the seeds by the leaf-cutting ants.

The study and understanding of the mirmecochory have become important tools for the comprehending the dynamics of establishment of many plant communities.

The period of the day only influenced the rate of removal in the tropical area, being higher in the nocturnal period. Why workers of A. Elas efetivamente dispersaram as sementes de S.

In this work the behavioral and ecological aspects of the interaction between ants and seeds were investigated. The contribution of vertebrates in seed removal was expressive in the tropical area. Three cortadeirqs of behavior with seeds of M. Another objective was to emphasize the important role the ants can exert in these environments.
