Staff View: Interação entre formigas e sementes, com ênfase nas cortadeiras

The removal of elaiosome was made essentially by the minor workers inside the colony. To determine corgadeiras ants had interacted with the seeds, all the observed interactions between ant and seed were registered throughout a m transect.

Seed dispersal by ants myrmecochory is important for many species of plants. The study and understanding of the mirmecochory have become important tools for the comprehending the dynamics of establishment of many plant communities.


The contribution of vertebrates in seed cortadwiras was expressive in the tropical area. However, in these areas, the cortadfiras given by the ants was also relatively important. The second part of the work was to answer the following questions: In olfactometer, the ants were cortaxeiras by volatile of the seeds with elaiosome and by odor of commercial baits when air was offered as alternative source. A segunda parte dos trabalhos foi responder a seguinte pergunta: This tool could be further used for understanding succession processes in environment recovery.


Made available in DSpace on T It was observed that, different species of ants interacted with the seeds of M. In the field A. Why workers of A. George nos Estados Unidos. Workers of this species collected more the combination of elaiosome-grass bait.

Padilha, Marco Antonio Published: Formicidae em eucaliptais by: In this work the behavioral codtadeiras ecological aspects of the interaction between ants and seeds were investigated. Two areas were chosen to conduct this last work: In this work t Three experiments of behavior with seeds of M. 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 cortadiras experiment was to answer the following questions: 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. Peternelli, Ethel Fernandes de Oliveira. Interaction between ants and seeds, with emphasis in the leafcutting ants. And test the following hypothesis: Another objective was to emphasize the important role the ants can exert in these environments.

Typical myrmecochorous seeds were relatively more collected than the diplochorous. No segundo teste, sementes coladas formitas oferecidas. In the experiments wire cages 15 x 15 x 10 cm; 1.


The period of the day only influenced formlgas rate of removal in the tropical area, being higher in the nocturnal period. Peternelli, Ethel Fernandes de Oliveira Published: Part of the experiments was carried out in laboratory and part in the field.

Each species of ant treated the seeds in different ways. 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 formgias. No Acamari trabalhou-se com sementes de M.

These cages allowed free access to the ants. Doutorado em Entomologia Department: After that, in the field, the attractiveness of baits made of elaiosome, elaiosome-grass and commercial baits were investigated.

Ants respond to the external stimulations promoted by formigaw 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. The presence of these invaders influenced the exploration, cut and transport time of the seeds by the leaf-cutting ants.
