Differentiation in Selection of Dicots and Grasses by the Leaf-Cutter Ants Atta capiguara, Atta laevigata and Atta sexdens rubropilosa
(California State University, 2009-01-01)
Besides foraging for grasses, the so-called grass-cutter ants, such as Atta capiguara (Hym., Formicidae, Attini), have shown, in the laboratory, a high preference for dicots including Acalypha spp. This preference has also ...

Comparative study of resistance to heat in two species of leaf-cutting ants
(Springer, 2015-02-01)
Atta laevigata and Atta capiguara are two species of leaf-cutting ants that are found in the pastures of Central Brazil and build huge underground nests linked to the outdoor environment by underground tunnels, which can ...
Interference of epicuticular wax from leaves of grasses in selection and preparation of substrate for cultivation of symbiont fungus by Atta capiguara (Hym. Formicidae)
(2005-06-01)
The selection of plants is one of the stages of foraging behavior, executed by leaf-cutting ants for the cultivation of symbiont fungus. Anatomical, biochemical and physiological characteristics of vegetal species are some ...
Method for the evaluation of insecticidal activity over time in Atta sexdens rubropilosa workers (Hymenoptera: Formicidae)
(2004-10-06)
The active ingredients used in the formulation of toxic baits for leaf-cutting ants (Hymenoptera: Formicidae) should possess a delayed action defined as an insecticidal activity whereby worker mortality is ≤15% at 24 hours ...
