Microdon tigrinus (Diptera, Syrphidae): Populational fluctuations and specificity to the nest of Acromyrmex coronatus (Hymenoptera: Formicidae)
(2007-11-15)
This study was performed in the southern and southeastern regions of Brazil, visiting numerous municipalities, over a period of 25 years, excavating nests of 12 species of leaf-cutting ants of the Acromyrmex genus. Larvae ...
The effect of plant diversity on fungus garden development and foraging behavior of leaf-cutting ants (Hymenoptera: Formicidae)
(2003-08-18)
The leaf-cutting ants forage a wide variety of plant species, used for symbiotic fungus cultivation. To better understand this tripartite complex interaction, 24 colonies of Acromyrmex subterraneus brunneus were conditioned ...

Contamination Route of Leaf-Cutting Worker Ants Analyzed Through a Fat-Soluble Tracer Dye in Toxic Bait
(Entomological Soc Brasil, 2019-04-01)
Our study seeks to discover contamination routes of leaf-cutting worker ants during chemical control by formicide baits. To do so, toxic baits containing fat-soluble tracer dye were provided to colonies of three subspecies ...
Polygyny, oviposition, life cycle and longevity of the three subspecies of leaf-cutting ants, Acromyrmex subterraneus (Hymenoptera: Formicidae)
(2018-12-25)
Research related to the comparative biology of phylogenetically close ant species has received little attention, although it is the basis for understanding the systematics of some sibling groups. The objective was to study ...
Description and morphometry of the sting apparatus in the three worker casts of Acromyrmex subterraneus brunneus (Formicidae, Attini)
(2007-11-15)
We studied the morphometry of the sting apparatus of Acromyrmex subterraneus brunneus workers by dissection and mounting of the structures on slides, and present here a brief description and illustrations. Sting apparatus ...
The effect of trail length on task partitioning in three Acromyrmex species (Hymenoptera: Formicidae)
(2003-05-19)
By comparing the behavior of three Acromyrmex (Hymenoptera, Formicidae) species during foraging on artificial trails of different lengths, we observed the occurrence of task partitioning and its relation to the food distance ...
