Interhabitat differences in ant activity on plant foliage: ants at extrafloral nectaries of Hibiscus pernambucensis in sandy and mangrove forests
(Blackwell Publishing LtdOxfordInglaterra, 2003)
Foraging activity pattern and herbivory rates of the grass-cutting ant Atta capiguara
(Springer, 2016-08-01)
The objective of this study was to investigate the seasonal change in the pattern of foraging activity in the leaf-cutting ant Atta capiguara and to provide an estimate of the annual herbivory rate of its colonies. We ...
Natural history of the Neotropical arboreal ant, Odontomachus hastatus: Nest sites, foraging schedule, and diet
(Univ ArizonaTucsonEUA, 2012)
Astilbin toxicity to leaf-cutting ant Atta sexdens rubropilosa (Hymenoptera: Formicidae)
(2005-04-18)
The toxicity of astilbin, isolated from Dimorphandra mollis, was tested in laboratory ingestion bioassays for the leaf-cutting ant Atta sexdens rubropilosa Forel. Worker ants that were fed an artificial diet daily to which ...
Synthetic amides toxic to the leaf-cutting ant Atta sexdens rubropilosa L. and its symbiotic fungus
(Wiley-Blackwell, 2006-02-01)
1 Nine synthetic amides similar to natural N-piperidine-3-(4,5-methylenedioxyphenyl)-2-(E)-propenainide and N-pyrrolidine-3-(4,5-methylenedyoxiphenyl)2-(E)-propenamide were synthesized and identified by their spectroscopic ...
Activity of Ricinus communis (Euphorbiaceae) and ricinine against the leaf-cutting ant Atta sexdens rubropilosa (Hymenoptera : Formicidae) and the symbiotic fungus Leucoagaricus gongylophorus
(Wiley-Blackwell, 2004-09-01)
The focus of this study was the identification of compounds from plant extracts for use in crop protection. This paper reports on the toxic activity of fractions of leaf extracts of Ricinus communis L (Euphorbiaceae) and ...
Effect of constituents of the foliar wax of Didymopanax vinosum on the foraging activity of the leaf-cutting ant Atta sexdens rubropilosa
(1998-01-01)
Leaf epicuticular waxes may affect substrate selection by leaf-cutting ants, and host recognition by several phytophagous insects. The influence of the crude epicuticular wax of Didymopanax vinosum E. March. (Araliaceae), ...
A metabolic pathway assembled by enzyme selection may support herbivory of leaf-cutter ants on plant starch
(2013-05-01)
Mutualistic associations shape the evolution in different organism groups. The association between the leaf-cutter ant Atta sexdens and the basidiomycete fungus Leucoagaricus gongylophorus has enabled them to degrade starch ...
Foraging behavior and mortality of ectatomma brunneum (Hymenoptera, Formicidae) in simultaneous exposure to ant baits and conventional diet in laboratory
(2010-04-14)
The Objective of This Wk. Was to Identify Whether the Presence of Leafcutting Ant Baits in the Foraging Arena of the Ant Ectatomma Brunneum (Smith) Affects Its Foragingbehavior or Causes Mortality in Lab. A Multiple Choice ...
Toxicity of sesame extracts to leaf-cutting ant Atta sexdens rubropilosa (Hymenoptera: Formicidae)
(2004-11-23)
Extracts of different sesame plant (Sesamum indicum, Linnaeus) organs were tested through ingestion and contact experiments to investigate their toxicity to Atta sexdens rubropilosa (Forel) workers. Dichloromethane extracts ...
