| description | Behavioral assays were conducted with individuals from monogynous and polygynous colonies of Acromyrmex subterraneus molestans to evaluate the discriminatory ability of ant workers. These bioassays showed that this subspecies could not discriminate among non-nestmates or nestmate workers. However, nestmates of these same colonies did discriminate among workers of another subspecies Ac. subterraneus subterraneus. When discrimation occurred there were no differences in the response of workers from either monogynous or polygynous colonies. Similarities or differences in the chemical profile of both subspecies explained the absence or occurence of aggressiveness among workers. The chemical profile of colonies of the same subspecies was very similar among them, although distinct among subspecies. The number of queens did not influence the cuticular chemical composition of the workers or their behavior.<br>Ensaios comportamentais foram conduzidos com indivíduos de colônias monogínicas e poligínicas de Acromyrmex subterraneus molestans a fim de avaliar a habilidade discriminatória de suas operárias. Estes bioensaios mostraram que esta subespécie não é capaz de discriminar entre não companheiras e companheiras de ninho. Entretanto, companheiras de mesma colônia discriminam operárias pertencentes à outra subespécie, Ac. subterraneus subterraneus. Nesta situação, não houve diferença na resposta de operárias oriundas de colônias monogínicas e poligínicas. Similaridades ou diferenças no perfil químico de ambas as subespécies podem explicar a ausência ou presença de agressividade entre operárias. O perfil químico de colônias de mesma subespécie foi muito similar entre si e muito distinto entre subespécies. O número de rainhas não influenciou a composição química cuticular das operárias e nem o seu comportamento discriminatório. |
