Plasticidade Do Comportamento De Forrageamento Em Formigas Cortadeiras

Abstract: O comportamento de forrageamento em insetos sociais é uma atividade complexa que envolve um sistema auto-organizável e pode ser estudado em nível de indivíduo e de colônia. Na sociedade de formigas nem todos os indivíduos participam da coleta de alimento. As operárias que executam essa tarefa, frequentemente, são as mais velhas e de maior tamanho. Nas formigas da tribo Attini o forrageamento é um processo complexo que consiste na exploração do recurso alimentar envolvendo seleção, corte e transporte para o nin… Show more

“…The tribe Attini (Hymenoptera: Formicidae, subfamily Myrmicinae) includes 12 genera of ants that cultivate symbiotic fungi on which they feed (Currie, 2001; Viana‐Bailez & Edringer, 2016). Two genera of this tribe, Atta and Acromyrmex , known as leaf‐cutting ants, differ from the other genera in that they provide fresh plant material to their fungal colonies (Weber, 1966).…”

“…The foraging activity of many leaf‐cutting ant species changes from diurnal to nocturnal during summer (Gamboa, 1976; Waller & Moser, 1990; Orr, 1992; Viana‐Bailez & Edringer, 2016; Caldato et al, 2016b). Foraging is often also interrupted by heavy rains in regions where the rainy season occurs during summer (Weber, 1966; Rockwood, 1975; Wirth et al, 1997; Kost et al, 2005; Viana‐Bailez & Edringer, 2016). Heavy rains disrupt the behaviour of laden ants and may even completely interrupt collective foraging (Farji‐Brener et al, 2018).…”

“…The complex social structure of A. sexdens enables it to adapt to environmental adversities, aiming to maximize energy input into the nest (Viana-Bailez & Endringer, 2016) and establish themselves in the area. Nevertheless, this study highlights the ecological significance of their natural enemies, which can disrupt their normal activities.…”

“…Temperature increase may modify the distribution range of leaf‐cutting ant species (Diamond et al, 2012), their foraging activity, herbivory levels and the extent of the damages they cause to plants. Foraging activity by leaf‐cutting ants varies between species and depends on biotic factors, such as the presence of other ants (Nobua Behrmann et al, 2017; Wirth et al, 1997) or natural enemies (Bragança et al, 1998; Guillade & Folgarait, 2015; Orr, 1992), and on abiotic factors such as air temperature and humidity (Caldato et al, 2016; Calheiros et al, 2019; Wirth et al, 1997), light intensity (Calheiros et al, 2019; Narendra et al, 2010), atmospheric pressure (Sujimoto et al, 2020; Viana‐Bailez & Endringer, 2016), rainfall (Farji‐Brener et al, 2018; Wirth et al, 1997) and wind (Alma et al, 2016a, 2016b).…”
