Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); The development of colonies of primitively eusocial wasps depends on intrinsic and extrinsic factors, namely social organization and climatic conditions. The present study was conducted to investigate how the process of replacement of the queen during the colonial cycle of Mischocyttarus cassununga takes place, and which are the determinant factors for its success. Our results showed that there are no disputes (fights) for hierarchical positions among other females after the disappearance of the queen. However, there is an increase on the overall frequency of aggressions, because of the efforts of the new queen (ex-2(nd) ranked female) in assuming control of the colony and affirming its reproductive dominance. Moreover, we recorded no alterations on the occupants of the hierarchical positions under the queen after its replacement, even in consecutive replacements in the same colony. We think that the climatic conditions, longevity of the queen, and the duration of the colonial cycle may be determinant during this process.

Environmental factors and management techniques were evaluated in São Paulo, Brazil, for enhanced production of Africanized queen honey bees. Queens were reared by the Doolittle method; 12 breeder, 6 cell-builder, and 36 3-frame nucleus colonies were used. Nine groups of four virgin Africanized queen honey bees were subjected to the following treatments: queens were either 1-2, 3-4 or 5-6 days old and were released into mating nuclei containing either capped brood, uncapped brood or no brood. This was repeated sixteen times between August 1990 and August 1992. Seven repetitions occurred during nectar flow periods and nine repetitions occurred during nectar-dearth periods. Overall, 59% of 576 queens were successfully introduced and mated. The best results (93% success) were obtained during nectar flows, with 3- to 4-day-old queens released into nuclei containing capped brood. During nectar dearths the best mating success came from queens introduced into broodless nuclei (63%), the age of the queen did not influence mating success. Mating success decreased when wind velocity increased; this was the only significant meteorological effect found.

Queen Christina of Sweden (1626–1689) was one of the most prominent European women of her time and a controversial person. The interest among her contemporaries in what she did and said was immense. Subsequently, the print medium developed quickly and made way for new genres and distribution channels. The name of the Swedish queen appears in early modern newspapers and journals, historiographical accounts, biographical and panegyrical texts, as well as in pamphlets. Rumors and gossip travelled between courts and countries, and the queen was considered frivolous, immoral, and androgynous. The tension between a desire to determine the sex of the Swedish queen and an interest in the functionality of gender found in the figure of Christina has shaped the narration of her life ever since. The objective of this article will be to investigate whether a pre-modern queen fits into the fluidity of post-gender discussions.; A rainha Christina da Suécia (1626-1689) foi uma das mulheres europeias mais proeminentes do seu tempo e também uma personalidade controversa. O interesse dos seus contemporâneos relativamente ao que era feito e dito por ela foi imenso. Simultaneamente, o meio impresso desenvolveu-se rapidamente, abrindo caminho para novos géneros e canais de distribuição. O nome da rainha sueca surge nos primeiros jornais e almanaques modernos...

This study aimed to estimate live weight, the length and the width of wing and abdomen and the length, the width and the height of thorax in newly emerged Africanized honeybee queens up to 192 hours and their influence on final quality regarding appropriate storage techniques in queen banking or incubator and to verify the possibility of using these parameters as selection criteria in honeybee breeding programs. Queen honeybees were produced in summer, autumn and winter. The queen production method used throughout the experiments was adapted from Doolittle, and 68 the queens were weighed at emergence. Data were analyzed in R software by regression analysis of queen weight at emergence according to life time after emergence, in two types of storage. The weight of queens emerged in queen banking and incubator was significantly different (p < 0.05), with mean values of 165.61 and 157.04 mg, respectively. Queens kept in an incubator and in queen banking showed no significant differences (p > 0.05) in wing length, abdomen length and thorax height. The weight of queen at emergence can be used as a selection criterion in honeybee breeding programs.

Physogastric queens of Melipona marginata were removed from their colonies in order to verify the acceptance of a new queen by workers. Colony strength was evaluated according to queen oviposition rate and comb diameters. Replacement was observed seven times. Its occurrence and speed related positively to colony strength, independently of queen's age. In weak colonies, queen replacement was observed only once, following colony population increase that occurred after introduction of combs from another colony. Worker oviposition after queen removal was observed three times: in a strong colony with virgin queens and males, and in two of the weak colonies. In the first two or three days of new queen oviposition, during which most of the eggs were eaten by the queen, worker oviposition preceded almost all provisioning and oviposition processes (POPs). After this period, worker oviposition decreased until it reached around 25% of the POPs. Daily oviposition rate of young queens decreased or was even interrupted by hatching of their first brood.
