The number of bacteria and yeasts occurring in the organic matter inside the nests were determined both in colonies of leaf-cutting ants reared on Eucaliptus alba (control) or Sesamum indicum (experimental). Sesame leaves induce imbalance and nests u

In this paper we describe how morphological castes can be distinguished using multivariate statistical methods combined with jackknife estimators of the allometric coefficients. Data from the polymorphic ant,Camponotus rufipes, produced two distinct

In an institutional setting in Brazil, the pharaoh’s ant, Monornorium phuruonis was found to be the dominant and most abundant ant present throughout the year. The only other regularly collected ant was the exotic Tupinomu melunoce hufum. However,

The colonization characteristics of two neighboring populations of Monomorium pharaonis in human structures in Brazil were compared. No differences in the seasonality of colonizations into fixed trap nests between the two populations were found. Howe

The immature development of pharaoh's ant, Monomorium pharaonis, workers was studied in a naturally collected Brazilian population. Three larval instars were confirmed by measuring maximal cephalic widths in cohorts of known age. Minimum egg to adult

Laboratory colonies of the leaf-cutting ants Atta sexdens that were fed daily with leaves of Canavalia ensiformis showed a high ant mortality, and a significant decrease in fungal garden volume, with complete depletion of nests after 11 weeks of trea

Leaf-cutting ants may be a serious pest for the agriculture and silviculture once they cut plant material to cultivate a symbiotic fungus, which is their main food source. Currently, chemical methods are largely used for controlling of these insects,

The development of Leucoagaricus gongylophorus, the fungus cultured by the leaf-cutting ant Atta sexdens was inhibited in vitro by synthetic compounds containing the piperonyl group. In addition, worker ants that were fed daily on an artificial diet
