Effect of Seasonal Variation on the Cuticular Chemical Composition of Atta laevigata (Smith 1858) (Hymenoptera: Formicidae)

Journal of Chemical Ecology
Cuticular hydrocarbons (CHCs) constitute an important class of chemical compounds present in the cuticular layer of insects, where their main functions are to prevent desiccation of the cuticle and as signals for intraspecific recognition. Studies concerning CHCs have shown a phenotypic flexibility of their composition, depending on environmental ...

Mandibular Gland Secretion in Different Castes of the Leaf-Cutter Ant Atta laevigata

Journal of Chemical Ecology, 1999
Gas chromatography analyses and behavioral assays showed that Atta laevigata, a highly polymorphic ant species, has a mandibular gland secretion that varies with castes. All castes contain 4-methyl-3-heptanone as the main component and its concentration is proportional to head size.

Nestmate recognition signals of the leaf-cutting ant Atta laevigata

Journal of Insect Physiology, 2002
Behavioral tests with field colonies of Atta laevigata were performed in order to identify the source of the odors used in nestmate recognition. We tested the postpharyngeal (PPG) and mandibular glands (MG) as putative organs producing chemical signals for nestmate recognition. Chemical analyses of PPG were also undertaken.

Péptidos Antimicrobianos de Atta laevigata

2021
The action of agents of biological origin as regulators of the immune system has been shown to be optimal; however, some limitations, such as secondary cytotoxicity, have generated in recent years the search for new molecules that effectively modulate this response without causing adverse effects.

Influence of the host plant on the relationship between the mass of Atta laevigata foragers and their loads

Caderno Pedagógico
The objectives were to compare the mass of Atta laevigata leafcutter ant workers and the mass of the loads between periods (morning and evening) and between foraged plant species; to correlate the mass of the workers with that of their loads; to compare ...
