“…First, carbohydrates are used as energy source for the nuptial flight (Jutsum & Quinlan 1978) and nest digging (Camargo et al 2013a). Next, lipids are used for egg production (reproductive and trophic), taking care of the offspring and fungus garden, and self-grooming (Augustin 2011; Camargo et al 2013b). Additionally, crude protein is mobilized for different purposes and its content declines over time as observed in the present study.…”

“…This positive correlation is reflected on the population, which achieved an average size of 650.5 ± 447.9 workers. Wide population variability is observed in 4-month-old colonies as demonstrated by Camargo et al (2013b), with a strong influence of the environment on their natural habitat (Camargo et al 2013b;Viera-Neto & Vasconcelos 2010;Seal & Tschinkel 2008). Probably, this variability is due to the availability of palatable resources for foragers and a consequent increase in fungal biomass responsible for the increase in population size and queen weight (Camargo et al 2013b).…”

“…Spatial aggregation is a common pattern of distribution in leaf-cutting ant nests [1] [2]. Spatial aggregation is probably associated with the availability of resources, which are heterogeneously distributed within a given habitat [3]. As a consequence, ants generally follow patterns of distribution characterized by areas with high densities of nests and areas with no or few nests [1] [3].…”

As a consequence, ants generally follow patterns of distribution characterized by areas with high densities of nests and areas with no or few nests [1] [3]. This pattern of distribution is important in order for leaf-cutting ants to maintain populations in areas with a high potential for resource exploitation, while ensuring success in offspring production and dispersal to new areas with available resources [1].…”

In this study, we investigated the spatial aggregation of old and incipient nests of Atta sexdens rubropilosa by fitting Poisson and Negative binomial models to nest abundance data. Our aim is to analyse the distribution of ant nests in eucalypt regrowth, Cerrado and native forest fragment. We also investigated the correlation between nest abundance and climatic factors, as well as different nest ages. When comparing nests of different ages we observed an aggregated pattern for both old and incipient nests. On the other hand, analysing the distribution of nests separately, only taking into account the different areas and respective borders, old nests exhibited an aggregated pattern and incipient nests showed a random pattern, except for native forest with ants exhibiting only an aggregated pattern. The levels of aggregation changed in response to different areas and border gradients, with more external borders showing higher aggregation than more internal borders. Temperature was the variable showing the highest correlation with nest abundance and the correlation between nests of different ages was totally depending on the different areas.

“…Despite the great advantages of having cutter ant colonies under controlled laboratory conditions for the development of new control products, few laboratories have colonies. In the studies the difficulties for the establishment and maintenance of the anthills are evidenced, considering the feeding one of the limiting factors of major importance because of the voracity of the insects [9], [10].…”

The establishment of colonies of Atta cephalotes cutter ants under laboratory conditions has been proposed for the study and development of plague control products. However, few laboratories in Colombia have colonies of Atta cephalotes cutter ants, with food being a limiting factor given their sensitivity, selectivity and voracity. In this study, the use of wheat germinated kamut (Triticum turgidum), quinoa (Chenopodium quinoa) and mung bean (Vigna radiata) as an alternative for the feeding of colonies under laboratory conditions y mango leaves like control, using mini-colonies was evaluated. In the study, mung bean sprouts and kamut wheat were preferred (100% load, 24 hours), compared to quinoa (89 ± 10% load, 24 hours). The determination of the effect of the sprouts on the growth rate of the mini-colonies was evaluated during 8 weeks, showing that the germinated kamut wheat and control treatment generated the best growth rates of fungus in the exponential phase (3.19 and 3.73 g / week respectively) compared with mung beans and quinoa (1 g / wk), supporting the potential of kamut wheat for the maintenance of colonies under laboratory conditions.
