Despite this species having constructed two royal cell, all (36) normal or dwarfed virgin queens, who had emerged had happened of common cells. Although it has a regular production of queens, the colony alone accepted queens after virgin 26º day of orphaned. The tax of emergency of Rv was bigger in the months most cold (April the September) of that in the months hottest (October the March), already the workers and the males had presented with constant emergencies during the year. The frequency of emergency of Rv was around 0 and 4,64%, of the workers between 68,48% and 99,26%, and for the males were between 0,74% and 30,04%. The frequency of emergency of caste of the queens just fertilized it was enters 90,54% the 100%, 0% and 0% 14.96%, for the workers, males and Rv respectively. It was possible also to evaluate time of oviposição of queens and workers, time of life cycle, minimum age to beginning of the position, as also give metric of some structures of chaste after the its birth to its differentiation / O processo de substituição de rainha para Plebeia catamarcensis envolve uma forte atratividade da rainha recém emergida, e reações especificas das operárias, que se alternam entre ataques e corte à rainha. As mesmas apresentaram ainda comportamentos relacionados à construção e oviposição de células de cria na ausência da rainha. Apesar de ter sido construídas duas realeiras, todas as rainhas virgens (Rv) normais ou anãs, emergiram de células comuns. Embora houve uma produção regular de rainhas, a colônia só aceitou as rainhas virgens após o 26º dia de orfandade. A taxa de emergência de Rv foi maior nos meses mais frios (abril a setembro) do que nos meses mais quentes (outubro a março). Já as operárias e os machos apresentaram emergências constantes durante o ano. A freqüência de emergência de Rv esteve em torno de 0 e 4,64%, das operárias entre 68,48% e 99,26%, e para os machos esteve entre 0,74% e 30,04%. A freqüência de emergência de castas das rainhas recém fecundadas esteve entre 90,54% a 100%, 0% e 0% a 14,96%, para as operárias, machos e Rv respectivamente. Foi possível também avaliar tempo de oviposição de rainhas e operárias, tempo de ciclo de vida, idade mínima para início da postura, como também dados métricos de algumas estruturas das castas após seu nascimento para sua diferenciação
