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.
Why workers of A. In the second test, glued seeds were offered; in the third test, the seeds were allowed to be explored by the workers of leaf-cutting ants with the presence of two invading species, Pheidole sp. In the experiments wire cages 15 x 15 x 10 cm; 1. In both the study areas, the research was conducted in two habitats, secondary forest and old field, using seeds of M.
Seed dispersal by ants myrmecochory is important for many species of plants.
Another objective was to emphasize the important role the ants can exert in these environments. No Acamari trabalhou-se com sementes de M.
Peternelli, Ethel Fernandes de Oliveira Published: In this work t Two areas were chosen to conduct this last work: Padilha, Marco Antonio Published: George nos Estados Unidos. The presence of these invaders influenced the exploration, cut and transport time of the seeds by the leaf-cutting ants.
Doutorado em Entomologia Department: The period of the day only influenced the rate of removal in the tropical area, being higher in the nocturnal period. It was observed that, different species of ants interacted formgas the seeds of M. 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.

Elas efetivamente dispersaram as sementes de S. Part of the experiments was carried out in laboratory and part in the field.
Seed dispersal Leaf-cutting ant Myrmecochory. In this work the behavioral and ecological aspects of the interaction between ants and seeds were investigated.
This tool could be further used for understanding succession processes in environment recovery. To compare the removal of seeds by ants and vertebrates in the two areas forest and old fieldtwo parallel m transects were established in each area within the Acamari or ESGR.
However, in these areas, the contribution given by the ants was also relatively important. No segundo teste, sementes coladas foram oferecidas. After that, in the field, the attractiveness of baits made of elaiosome, elaiosome-grass and commercial baits were investigated.
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. 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: To determine which ants had interacted with the seeds, all the observed interactions between cortadeirws and seed were registered throughout a m transect. Each species of ant treated the seeds in different ways.

Workers of this species collected more the combination of elaiosome-grass bait. A segunda parte dos trabalhos foi responder a seguinte pergunta: They effectively dispersed the seeds of S. Thus the aim of this last experiment was to answer the following questions: The contribution of vertebrates in seed removal was expressive in the tropical formias. Made available in DSpace on T
