Through physiological ovary studies and the use of indoor systems, we improved egg production and offspring survival of Copris tripartitus Waterhouse. We also tested the effects of a lack of maternal care on offspring. Second larval instars died when brood balls were separated from females. Third instar larvae or pupal stage survival was significantly lower than that recorded in brood balls cared for by females. New adult body weights and pronotal sizes were also significantly lower in those emerged from brood balls separated from mothers than those cared for by them. The results shed light on the survival and reproduction of adults that emerged indoors as compared to those observed in populations under natural conditions.
