Five colonies from three colony development stages (namely, pre-emergence, worker-producing and male-producing) were analyzed. The main results were: irrespective of colony age, castes were always morphologically indistinguishable; non-inseminated ovary-developed females were found in four colonies; because differences of castes were physiological rather than morphological, castes are evidently post-imaginally determined and this is probably taking place according to the colony conditions. These findings support the occurrence of caste totipotency in Parachartergus fraternus.470-483engPolistinaeEpiponiniParachartegus fraternuscaste differencescolony cycleproductivityArtigo10.2317/E-40.1WOS:000225775300013Acesso restrito83471317041536870000-0003-0207-1067
