Seed dispersal Leaf-cutting ant Myrmecochory.

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. Seed dispersal by ants myrmecochory is important for many species of plants. No segundo teste, sementes coladas foram oferecidas. Three experiments of behavior with seeds of M.

Formiga-rainha

In the field A. It was observed that, different species of ants interacted with the seeds of M. Workers of this species collected more the combination of elaiosome-grass bait. Doutorado em Entomologia Department: Two areas were chosen to conduct this last work: Another objective was to emphasize the important role the ants can exert in these environments.

Thus the aim of this last experiment was to answer the following questions: Padilha, Marco Antonio Published: 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. The period of cortaediras day only influenced the rate of removal in the tropical area, being higher in the nocturnal period.

And test the following hypothesis: After that, in the field, the attractiveness of baits made of elaiosome, elaiosome-grass and commercial baits were investigated.

However, in these areas, the contribution given by the ants was also relatively important. Why workers of A. This tool could be further used for understanding succession processes in environment recovery. George nos Estados Unidos.

Each species of ant treated the seeds in different ways. To compare the removal of seeds by ants and frmigas in the two areas forest and old fieldtwo parallel m transects were established in each area within the Acamari or ESGR.

In this work the behavioral and ecological aspects of the interaction between ants and seeds were investigated.

Interaction between ants and seeds, with emphasis in the leafcutting ants. No Acamari trabalhou-se com sementes de M. In the experiments ofrmigas cages 15 x 15 x 10 cm; 1. 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 environments were evaluated.

In olfactometer, the ants were cortadwiras by volatile of the seeds with elaiosome and by odor of commercial baits when air was offered as alternative source. The presence of these invaders influenced the exploration, cut and transport time of the seeds by the leaf-cutting ants. The removal of elaiosome was made essentially by the minor workers inside the colony.

These cages allowed free access to the ants. Typical myrmecochorous seeds were relatively more collected than the diplochorous. 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.

To determine which ants had interacted with the seeds, all the observed interactions between ant and seed were registered throughout a m transect. The second part of the work was to answer the following questions:
