As formigas Pogonomyrmex (S = 2) sao coletoras de sementes (SILVESTRE; BRANDAO; SILVA, 2003) e frequentemente encontradas em ambientes abertos no Sul do Brasil (LUTINSKI et al., 2014), contribuindo assim para a regeneracao da APP ao dispersarem sementes.
(1958) showed that material treated with either acetone corpse extracts of Pogonomyrmex badius workers or oleic acid alone resulted in the same necrophoric behavioral response.
Heavy metal distribution and bioaccumulation in Chihuahuan Desert Rough Harvester ant (Pogonomyrmex rugosus) populations.
The granivorous red harvester ant, Pogonomyrmex barbatus, selectively predates the mericarps of Salvia texana and in doing so influences the composition of grass and forb communities in the Edwards Plateau, Texas (Nicolai, 2005).
Other researchers have noted the presence of harvester ants (Pogonomyrmex), velvet ants (Timulla), and scorpions (Scorpiones) in stomachs of Sonoran Desert toads (Gates, 1957; Cole, 1962), suggesting these toads are capable of eating prey that have formidable biting and stinging defenses.
Habitat segregation based on soil texture and body size in the seed-harvester ants Pogonomyrmex rugosus and P.
Thus, it was shown that Pogonomyrmex rugosus Emery, 1895 (Hymenoptera: Formicidae), accumulate heavy metals from seeds that they consume making them ideal bioindicators of contamination in above mentioned ecosystem.

For reasons still unknown, colonies of Florida harvester ants (Pogonomyrmex badius) abandon their lovely nests about once a year and dig a new one.
apiculatum tambien tiene relaciones trofobioticas con otros hemipteros, como membrasidos (Vanduzea segmentata Fowlwe), e incluso con otras hormigas (Pogonomyrmex barbatus Smith, Camponotus sayi Emery y Solenopsis xyloni McCook).
La funcion iconica de una senal quimica esta bien ilustrada por la sustancia de alarma que segrega la hormiga Pogonomyrmex badius: si el peligro para la colonia es momentaneo, la senal (la cantidad de feromona liberada) se desvanece rapidamente dejando a la mayor parte de la colonia inalterada.
