“…Autocratic mass recruitment (AMR): scouts recruited the exact number of collectors required to retrieve the discovered resouce, by using a pheromone trail leading from the food to the nest (Jaffe, 1980;Jaffe et al, 1985). Scouts assessed the amount of food to be collected with a given error up to _+ 95 % of the resource size.…”

“…This would explain the finding that among ants, only leaf-cutters (Attini), which forage for plants relatively large in relation to individual ants, use the autocratic mass recruitment system. All other species tested used the democratic mass recruitment system (Jaffe et al, 1985). The democratic mass recruitment system is the most efficient for foraging for highdensity resources.…”

“…As a respectable amount of theoretical knowledge and experimental data has been accumulated on foraging strategies and recruitment systems of ant societies (e.g. Taylor, 1978;Jaffe, 1980Jaffe, , 1984Jaffe et al, 1985;Goss et al, 1989;Beckers et al, 1989;Deneubourg and Goss, 1989), the model was developed for food retrieval in ants, but it is thought to apply, with the corresponding modifications, to any eusocial colony where the effort made to search for a resource directly affects the available force for its eventual retrieval.…”

SummaryA numerical model of an eusocial colony foraging for food showed that, for each set of values of resource density, resource size and recruitment system employed, a given optimal proportion of scouts in the colony maximize the amount of resources retrieved by a colony during a fixed period. The model predicts that ants using mass recruitment systems should have larger colonies with small foragers, and should forage on large food sources. Retrieval of small food sources by small colonies is best achieved with large workers using individual foraging strategies. For mass foragers, several food sources are best retrieved using democratic decision-making systems in recruitment, whereas for very large food sources at very low mean food patch density, autocratic decision-making systems are optimal. Some of the experimental evidence available is discussed in the light of these findings, as they confirm the prediction that large colonies with small workers have mass recruitment systems, whereas workers of small colonies with large workers are generally lone foragers.

“…Para otimizar o forrageamento as formigas podem apresentam diferentes tipos de estratégias (solitária, com recrutamento, uso de feromônio) (Hölldobler & Wilson, 1990). Essas estratégias variam entre as espécies, o processo de tomada de decisão da forrageadora, as informações ambientais e as características do alimento (Jaffe et al, 1985). Neste trabalho serão abordadas duas estratégias: o forrageamento solitário e o recrutamento por tandem, característicos da espécie pesquisada, Pachycondyla striata Smith 1858.…”
