1. Biologia reprodutiva de rainhas e machos de Tetragonisca angustula (Hymenoptera: Meliponini) / Reproductive biology of the queens and males of Tetragonisca angustula (Hymenoptera: Meliponini)
The stingless bees (Hymenoptera: Meliponini)present a haplodiploid sex determination system with complementary sex determination in a single locus. Such a system is a large genetic load for the group and thus the genetic diversity of male\ s aggregations near the nests is essential to minimize the chances of inbreeding. The interactions among the stingless b

2. Proteomic analysis of the spermathecae in inseminated and virgin queens of Atta sexdens rubropilosa FOREL, 1908 (Hymenoptera: Formicidae) / Análise proteômica de espermatecas de fêmeas virgens e rainhas fecundadas de Atta sexdens rubropilosa FOREL, 1908 (Hymenoptera: Formicidae)
As formigas cortadeiras do gênero Atta, popularmente conhecidas como saúvas, pertencem à Tribo Attini, família Formicidae e ordem Hymenoptera, a qual também inclui as abelhas e as vespas. Assim como na maioria das fêmeas de insetos, as rainhas deste gênero possuem um órgão que armazena espermatozóides após o acasalamento, conhecido como espermatec

3. Estudo comportamental, perfil dos hidrocarbonetos cuticulares e morfologia das glândulas mandibulares e intramandibulares de rainhas de Melipona scutellaris com diferentes idades / Behavioural study, cuticular hydrocarbon profiles and morphology of the mandibular and intramandibular glands of the queens of Melipona scutellaris with differents ages
The virgin queens of Melipona scutellaris, as others species of the genus Melipona, are attacked and killed for workers. As exist few information about recognition of this virgin queens, this work had as purpose to test the hypothesis that the virgin queens of M. scutellaris are identified by workers for the use of chemical signal. For this, the behaviour, t

4. Changes in the size of cephalic salivary glands of Apis mellifera and Scaptotrigona postica (Hymenoptera: Apidae) queens and workers in different life phases
The bee species of the Apinae, in addition to the thoracic salivary glands, possess a pair of cephalic glands originating as branches of the excretory duct that crosses the head. These glands are known as cephalic salivary or labial cephalic glands. The degree of development of these glands in newly emerged, nurse and forager workers and virgin and egg-layin

5. Substitution of Queens in Colony Plebeia catamarcensis (Hymenoptera : Apidae: Meliponina), and the Frequency of Caste in the Emergent Mass of cells / SUBSTITUIÇÃO DE RAINHAS EM COLÔNIAS DE PLEBEIA CATAMARCENSIS (HYMENOPTERA: APIDAE: MELIPONINA), E A FREQÜÊNCIA DE CASTAS NOS FAVOS EMERGENTES
The process of substitution of queen for Plebeia catamarcensis involves one strong attractiveness of the queen just emerged, and specify reactions of the workers, who if alternate between attacks and court the queen, the workers had still presented behaviors related to the construction and oviposition of cells in the absence of the queen. Despite this specie

7. Histology and Histochemistry of the Reproductive Tract of Melipona quadrifasciata anthidioides (Hymenoptera, Apidae) in Virgin and Physogastric Queens / Histologia e histoquímica do aparelho reprodutor de Melipona quadrifasciata anthidioides (Hymenoptera, Apidae) em rainhas virgens e copuladas
Due to the economic and ecological importance, and the extinction risk that Meliponini is experiencing, many works were developed in search of understanding of reproductive biology of these bees. The importance of the mating for ovaries development and oocytes maturation in insects has been investigated, but there are few research concerning the consequences

8. Influence of the workers bee behavioral status on the preoviposition period and survival of queens of Melipona quadrifasciata Lep. (HYMENOPTERA:MELIPONINI) in laboratory conditions. / Influência do status comportamental das operárias sobre o período de pré-oviposição e sobrevivência de rainhas de Melipona quadrifasciata Lep. (Hymenoptera: Meliponini) em condições de laboratório
In this work it was aimed at a) to investigate the influence of the workers bee behavioral status of different origins in the recognition process and defensive behavior; b) the influence of the age of the queens and of the workers bee behavioral status in the acceptance process of virgin queens; c) influence of the workers bee behavioral status on the surviv

9. Adaptive behavior of Scotocryptus melitophilus Reitter (Coleoptera, Leiodidae) to live with its host Melipona quadrifasciata Lepeletier (Hymenoptera, Apidae)
Forty six beetles Scotocryptus melitophilus Reitter, 1881 collected in a nest of Melipona quadrifasciata Lepeletier, 1836 were studied. All beetles were put together in a large petri dish with 14 males, 14 virgin queens and 14 workers of M. quadrifasciata, which was not aggressive towards the S. melitophilus and flew with 3 to 10 beetles attached to them.

10. Queen reproductive state modulates pheromone production and queen-worker interactions in honeybees
The mandibular glands of queen honeybees produce a pheromone that modulates many aspects of worker honeybee physiology and behavior and is critical for colony social organization. The exact chemical blend produced by the queen differs between virgin and mated, laying queens. Here, we investigate the role of mating and reproductive state on queen pheromone pr

11. Fighting for a harem of queens: physiology of reproduction in Cardiocondyla male ants.
Several species of the ant genus Cardiocondyla produce dimorphic males, which exhibit sharply different mating strategies. Winged males typically disperse to mate outside the nest, whereas wingless, ergatoid males stay in the nest and aggressively employ their mandibles against competing ergatoid males to monopolize the virgin queens eclosing in the nest.

12. Tissue Localization of the Endosymbiotic Bacterium “Candidatus Blochmannia floridanus” in Adults and Larvae of the Carpenter Ant Camponotus floridanus
The distribution of endosymbiotic bacteria in different tissues of queens, males, and workers of the carpenter ant Camponotus floridanus was investigated by light and electron microscopy and by in situ hybridization. A large number of bacteria could be detected in bacteriocytes within the midguts of workers, young virgin queens, and males. Large amounts of b
