    Ptiloneuridae created by Roesler (1940), belongs to the suborder Psocomorpha, Infraorder Epipsocetae. Ptiloneuridae currently has 12 genera, including those already published as results of this thesis. Triplocania Roesler (1940), the focus of this study, is one of these 12 genera and it has a Neotropical distribution, range from South of Mexico to South of Brazil. The type-species of the genus is T. magnifica Roesler, which type series was collected by Fritz Plaumann, at the municipalitie of Nova Teutônia, Santa Catarina, Brazil. The last diagnosis of Triplocania was made by Garcia Aldrete in 2012 and is obsolete due to the expressive number of new species described after 2012 (20 species), currently totalizing 48 valid species to the genus. Even though Triplocania had been present in a few phylogenetic studies, there have never been a study directed to test the monophyletism and the internal relationships of the genus, as well as the inexistence of a revision of known species. The objectives of this study were: describe new taxa of Ptiloneuridae, with emphasis in Triplocania, review the described species of Triplocania with actualization of its generical diagnosis, present hypothesis of relationship between Triplocania species, test its monophyletism and elaborate an identification key for species of Triplocania. Furthermore, it was proposed to actualize the generic relationships of Ptiloneuridae based on each typespecies of each genus; actualize the diagnosis of Ptiloneuridae and create a new methodology of storing for Psocoptera, to prevent the loss of non-mounted parts on slides. In this study was published a new genus in Ptiloneuridae, called Brasineura Silva-Neto & García Aldrete with three included species. Posteriorly, another paper was printed proving the monophyletism of Brasineura and Loneuroides García Aldrete demonstrating the generic relationships of Triplocania. A new species of Timnewia García Aldrete (T. jeaneae Silva-Neto, García Aldrete & Rafael) was later published, removing the status of monotypic from this genus. In total, 20 new species of Triplocania were published and its monophyletism was tested was well as its internals relationships. As result, Triplocania as known before would be paraphyletic. However, with the proposal of the synonym of the three monotypical genera (Belicania García Aldrete, Perucania New & Thornton e Omilneura García Aldrete) with Triplocania, as well as with the new two combinations proposed for Perucania longiareola and Omilneura circumyittata and the revalidation of the original combination of Belicania cervantesis. This way, Triplocania was found to be monophyletic. The revision of Triplocania was made, the diagnosis of Triplocania was actualized, as well as diagnosis for each species, which were either revised or made for the first time. Some morphological data were added to original descriptions of some species. Furthermore, are presented the redescriptions and illustrations of T. magnifica and T. spinosa Mockford, as well as illustration and description of female from T. spinosa. The original combination of T. chulumanensis Williner is made. Identification key and maps for geographical distributions (with new records) of Triplocania species are presented. A new diagnosis for Ptiloneuridae is proposed. Lastly, it was printed a new methodology for storing Psocoptera in CD boxes, which helps to prevent the loss of non-mounted parts in slides.Ptiloneuridae, criada por Roesler (1940), pertence à subordem Psocomorpha, infraordem Epipsocetae. Ptiloneuridae atualmente, incluindo os artigos publicados como fruto da presente tese, possui 12 gêneros. Triplocania Roesler (1940), objeto central do estudo proposto aqui, é um destes 12 gêneros e possui distribuição Neotropical, desde o Sul do México até o Sul do Brasil. Triplocania tem como espécie tipo T. magnifica Roesler, cuja série sintípica foi coletada por Fritz Plaumann no município de Nova Teutônia, Santa Catarina, Brasil. A última diagnose de Triplocania foi feita por Garcia Aldrete em 2012 e encontra-se obsoleta devido ao aumento expressivo do número de espécies novas descritas após 2012 (20 espécies) totalizando atualmente 48 espécies válidas para este gênero. Mesmo presente como representante em alguns trabalhos filogenéticos, nunca houve um estudo direcionado a testar seu monofiletismo, nem as relações internas de Triplocania, tão pouco uma revisão das espécies já descritas. Os objetivos deste estudo foram: descrever táxons novos de Ptiloneuridae com ênfase nas espécies de Triplocania, revisar as espécies já descritas de Triplocania e atualizar a sua diagnose genérica, apresentar hipóteses de relacionamentos filogenéticos entre as suas espécies, testar o seu monofiletismo e elaborar uma chave de identificação para todas as espécies. Além disso, foi proposto atualizar as relações genéricas de Ptiloneuridae com base na espécie tipo de cada gênero; atualizar a diagnose de Ptiloneuridae e criar uma nova metodologia de armazenamento para Psocoptera que evite a perda das partes não montadas em lâmina. Neste estudo, foi publicado um novo gênero para Ptiloneuridae denominado Brasineura Silva-Neto & García Aldrete, com três espécies novas, posteriormente foi publicado outro artigo comprovando o monofiletismo de Brasineura e de Loneuroides García Aldrete e estabelecendo as relações genéricas em Ptiloneuridae. Foi publicada uma nova espécie de Timnewia García Aldrete (T. jeaneae Silva-Neto, García Aldrete & Rafael), retirando o status monotípico deste gênero. Foram publicadas 20 espécies novas de Triplocania, foi testado o seu monofiletismo e a relação entre suas espécies foi proposta. Como resultado Triplocania como conhecido atualmente seria parafilético. Entretanto, com a proposta de sinonímias dos três gêneros monotípicos (Belicania García Aldrete, Perucania New & Thornton e Omilneura García Aldrete) com Triplocania e as duas novas combinações propostas para Perucania longiareola e Omilneura circumvittata e a revalidação de combinação original para Belicania cervantesis, Triplocania permaneceu como monofilético. Triplocania foi revisada, a diagnose genérica foi atualizada, a diagnose para cada espécie foi revisada ou feita pela primeira vez, algumas informações morfológicas foram acrescentadas complementando as descrições originais, as redescrições e ilustrações de T. magnifica e de T. spinosa Mockford, bem como a descrição e ilustração da fêmea de T. spinosa foram feitas e a revalidação de combinação original foi proposta para T. chulumanensis Williner. Além disso, uma chave de identificação ilustrada e mapas de distribuição geográfica (com novos registros) das espécies de Triplocania foram apresentados. Uma nova diagnose de Ptiloneuridae também foi proposta. Por fim foi publicada uma nova metodologia de armazenamento para Psocoptera em caixa de Cd que evita a perda das partes não montadas em lâmina

    Iological and behavioral aspects of two laboratory strains of ceratitis capitata (diptera: tephritidae): the influence of periodic introduction of wild flies in the colony

    Get PDF
    The healthy maintenance of insects reared under laboratory conditions requires strategies to retain the natural characteristics of their life-histories traits. Rearing strategies include artificial selection to laboratory conditions, hybridization with compatible strains, and supplying the colony with wild individuals. We compared behavioral as well as life-history aspects of two laboratory strains of Ceratitis capitata Wiedemann (Diptera, Tephritidae) that had either been reared for 15-20 years under laboratory conditions with or without introducing wild specimens (Lab-Pop and Hybrid-pop, respectively). The parameters evaluated were: performance and food ingestion of immatures, adult size and longevity, female oviposition preference and fecundity, egg viability, and mating choice. Analyses of these parameters were conducted under laboratory rearing conditions. The largest differences observed between the two strains were related to behavioral components: food ingestion rate at the larval stage and oviposition behavior. In general, Lab-Pop individuals were less selective and more adapted to the artificial diet than Hybrid-Pop individuals (diet consumption), but there were no significant differences between the two strains in terms of percentage of emergence, egg viability, adult size, fecundity, and mating choice. It is suggested that the use of hybrid strains is more appropriate than the use of strains without the incorporation of wild individuals, especially in studies that involve behavioral parameters, as hybrid strains behave very similarly to wild populations, according our previous studies

    In learning scenarios, the main focus should be on knowledge about the learner's strengths and weaknesses. In this context, this article aims to present the results obtained in the previous investigation of the learning styles of teachers in continuing education, in the perspective of the development of strategies that take into account the singularities of the teacher / student. This investigation deals with a case study on teachers in a broad sense in the area of Environmental Education, in a hybrid model, with classroom and virtual environment, offered by a public University. We sought to analyze the responses to promote personalization in the classroom and virtual classroom activities based on pedagogical strategies that included all styles of trainees present. To identify the learning style, an open questionnaire was applied, based on the model by Kolb, where a sample of 57 respondents was obtained, where different learning styles were identified among the course participants. The results indicate that training courses designed for the teaching professional who seek knowledge about the specificities of this professional, using instruments that value and recognize their opinion, favor them to be protagonists of their own training.Em cenários de aprendizado, o foco principal deve estar no conhecimento sobre as potencialidades e fragilidades do aprendente. Neste contexto, o presente artigo tem como objetivo apresentar os resultados obtidos na investigação prévia dos estilos de aprendizagem de professores em formação continuada, na perspectiva da elaboração de estratégias que levem em consideração as singularidades do professor/cursista. Esta investigação trata de um estudo de caso sobre professores em curso lato sensuna área de Educação Ambiental, em modelo híbrido, com ambiente presencial e virtual, ofertado por uma Universidade pública. Buscou-se analisar as respostas para promover uma personalização nas atividades da sala de aula presencial e virtual baseando-se em estratégias pedagógicas que contemplassem todos os estilos dos formandos presentes. Para identificação do estilo de aprendizagem foi aplicado questionário aberto, baseado no modelo de Kolb, onde se obteve uma amostra de 57 respondentes, onde se identificou estilos de aprendizagem diversos entre os cursistas. Os resultados apontam que formações elaboradas para o (a) profissional docente que buscam o conhecimento sobre especificidades deste profissional, a partir de instrumentos que valorizem e reconheçam sua opinião, favorecem para que sejam protagonistas da própria formação.En los escenarios de aprendizaje, el enfoque principal debe estar en el conocimiento sobre las fortalezas y debilidades del alumno.
