Um percurso nos Bólides de Hélio Oiticica / Um percurso nos Bólides de Hélio Oiticica

Angela Varela 10 August 2009 (has links)
O presente estudo analisa as transformações por que o Bólide passa no decurso da obra de Hélio Oiticica, na qual assume diferentes aspectos de 1963 a 1980. Pode-se dizer que, mais do que configurar objetos ou mesmo proposições, o Bólide oferece possibilidades abertas a um comportamento criativo. Ele é parte constitutiva de uma dinâmica própria ao Programa de Oiticica que redimensiona e rearticula seus elementos continuamente; é na particularidade dessa dinâmica que deve ser abordado. No processo experimental do artista, a cada inscrição, o Bólide instaura uma nova significação ele possui tantas significações quantas foram suas inscrições , de modo que estudá-lo implica restabelecer constantemente articulações de significados. Primeiramente, então, o estudo aborda os Bólides cujas estruturas estão vinculadas às experiências do artista com a cor. Entende-se que essas peças ampliam os limites formais do objeto por meio do corpo da cor. Num segundo momento, a análise incide sobre os Bólides configurados a partir de materiais retirados do contexto local, tais como brita, conchas e lata. A especificidade desses elementos, conjugada com uma estrutura formal aberta, reforça o anseio de Oiticica por instaurar uma experiência artística de cunho autônomo. Em seguida, o estudo dedica-se aos Bólides relacionados com os conceitos de suprasensorial e crelazer, que se estruturam como extensões do corpo do participador e podem atingir a escala arquitetônica. Por fim, são abordados o Para-bólide e os Contra-bólides, que trazem uma nova dimensão a essa ordem propositiva. / This study analyzes the transformations that the Bólide (Fireball) undergoes throughout the work of Hélio Oiticica, when from 1963 to 1980, it takes on different aspects. It can be said that more that shaping objects or even proposals, the Bólide discloses new possibilities for a creative behavior. The Bólide is a component of dynamics inherent to Oiticicas program that continuously reshape and rearticulate its elements. It is in the peculiarity of these dynamics that it should be approached. Studying them involves a constant renewal of new mingling of meanings. First then, the study approaches the Bólides whose structures are tied to the artists experiences with color. It is perceived that these pieces expand the formal boundaries of the object by means of the body of color. In a second instance, analysis focuses on the Bólides fashioned from materials taken from the local context such as gravel, shells and tin. The specificity of these elements together with an open formal structure strengthens Oiticicas craving to implant an artistic experience with an autonomous imprint. From then on, the study is centered on the Bólides related with concepts of supersensorial and creleisure, which are structured as extensions of the participants body and may attain an architectural scale. And finally, the Para-bólide and the Contra-bólides that bring forth a new dimension to this proposed order are approached.

Bárbaro e Nosso. Indigenismo y vanguardia en Oswald de Andrade y Gamaliel Churata / Bárbaro e nosso. Indigenismo and avant-garde in Oswald de Andrade e Gamaliel Churata

Meritxell Hernando Marsal 26 July 2010 (has links)
Este trabalho cria um diálogo entre dois movimentos literários de vanguarda surgidos nos anos vinte do século passado no Peru e no Brasil: por um lado, a vanguarda indigenista de Puno dirigida por Gamaliel Churata, que afirmava tanto sua identidade regional e étnica, como os procedimentos vanguardistas empregados para expressá-la; e, por outro lado, seu contemporâneo brasileiro, a Antropofagia de Oswald de Andrade, que desde a metrópole paulista reunia elementos semelhantes (o indígena e o impulso vanguardista) com distintos propósitos. A tese pretende refletir sobre a imagem do indígena elaborada por ambos os movimentos nas revistas Boletín Titikaka e Revista de Antropofagia e que está subjacente em El pez de oro de Churata e em Serafim Ponte Grande de Andrade; esta imagem foi usada como plataforma simbólica a partir da qual enfrentar as configurações históricas, literárias e sociais hegemônicas, e elaborar um projeto de modernidade nacional. Os limites e aporias de ambos os programas, que falavam através de uma voz emprestada e ausente, não ressaltados com a intenção de mostrar as contradições da sociedade em que foram gestados. / The present work creates a dialogue between two literary avant-garde movementes that emerged in the twenties of last century in Peru and Brazil: on the one hand, the avant-garde\'s indigenismo of Puno directed by Gamaliel Churata, that claimed both their regional and ethnic identity, as the procedures avant-garde use to express it; and, on the other hand, his Brazilian contemporary, the Oswald de Andrade\'s Anthropophagy, who from the São Paulo metropolis brought together similar elements (the indigenous and the avant-garde impulse) with different intentions. The thesis intends to discuss the indigenous\'s picture drawn by both movements in the journals Boletín Titikaka and Revista de Antropofagia and present in El pez de oro by Churata and Serafim Ponte Grande by Andrade; this image was used as a symbolic platform which deal with historical, literary and perplexities of both programs, which spoke through an absent voise, are underlined with the intention of showing the contradictions of their society.

Subversão e resistência no Japão pós-guerra: os filmes de Terayama Shūji / Subversion and resistance in postwar Japan: the films of Terayama Shūji

Larissa Lessa 18 May 2018 (has links)
Esta pesquisa tem como objetivo o mapeamento do espaço que ocupa Terayama Shūji, poeta, escritor, dramaturgo e diretor de cinema japonês, frente ao período histórico a que pertenceu e frente às teorias da vanguarda e do pós-modernismo. A investigação se inicia com o período do pós-guerra no Japão, quando em meio a protestos e ansiedades políticas, floresce na capital do país uma nova vanguarda artística. O primeiro capítulo é dedicado a um exame do teatro angura e da nova onda do cinema, dois movimentos dos quais Terayama fez parte. Procura-se então delinear suas propostas artísticas e suas principais influências, japonesas e estrangeiras, examinando como seu trabalho se aproxima ou se afasta do paradigma pós-moderno conforme teorizado principalmente por Fredric Jameson, mas levando em conta reflexões sobre as aplicações desse conceito especificamente no Japão. Por fim, o último capítulo se debruçará sobre dois longas-metragens do diretor Joguem seus livros, vamos às ruas, de 1971, e Pastoral: Morrer no campo, de 1974 de modo a encontrar exemplos do seu caráter experimental, subversivo, de sua insurreição contra as instituições da família e do Estado e de suas complexas relações com a política, a história, o pastiche e a espetacularização. / This research aims at mapping the space occupied by Terayama Shūji, a Japanese poet, playwright and filmmaker, in his historical context and in relation to avant-garde and postmodernism theories. The investigation begins with postwar Tokyo, when amid protests and a climate of political anxiety, a new avant-garde movement starts to flourish. The first chapter is dedicated to an examination of the angura theatre and the Japanese new wave, two of the movements Terayama was part of. We shall then trace his general artistic views and main influences, Japanese and foreign, examining how they relate to postmodern characteristics as theorized mainly by Fredric Jameson, but also inquiring at how this very concept can apply to the Japanese context. In the last chapter, we shall take two of Terayamas feature films Throw Away Your Books, Rally In The Streets and Pastoral: To Die in The Country for further analysis, in order to find more specific examples of his experimental and subversive character, his rejection of the institutions of family and the State, and his complex relationship with politics, history, pastiche and spectacularization.

A (re)composição do material musical em Musik für Renaissance-Instrumente de Mauricio Kagel / The (re)composition of the musical material in Musik für Renaissance-Instrumente of Mauricio Kagel

Rafael Ramalhoso Alves 24 November 2015 (has links)
O objetivo deste trabalho é analisar a relação que a peça Musik für Renaissance-Instrumente (1966), de Mauricio Kagel (1931-2008), estabelece com o material musical da tradição e das vanguardas, na segunda metade do século 20. A partir da definição de material musical em Adorno investigaremos historicamente a crítica que se delineia em sua peça com relação às posturas estéticas em questão. Este trabalho pretende refletir criticamente sobre o sentido do movimento de interpretação historicamente informada e dos movimentos de vanguarda, identificando suas convergências e afinidades estéticas. Por fim, nosso objetivo é traçar o sentido estético e filosófico da obra de Kagel no contexto musical de sua emergência, buscando refletir sobre a importância de sua obra para o contexto atual de produção musical. / The aim of this research is to analyze the relation established by Mauricio Kagel\'s Musik für Renaissance-Instrumente with traditional musical material and also with material built by the musical avant-garde from the second half of the 20th century. Based on the definition of musical material in Theodor Adorno\'s philosophy we also intend to investigate through historical perspective how Kagel\'s criticism in composition applies to both of the aforementioned tendencies. Furthermore a critical assessment of the historical interpretation movement as well as of the avant-garde has been carried out, with the main purpose of establishing their mutual aesthetical affinities. Lastly, our foremost objective was to outline the meaning of Kagel\'s composition in the context of its appearance, in order to ponder about its importance for contemporary context of musical production.

Det sublima och det absurda : en kritisk närläsning och analys av begreppens kontaktytor utifrån Lyotard och Camus / The Sublime and the Absurd : a critical close reading and analysis of points of contact between the concepts

Gregemar, Erik January 2017 (has links)
I denna uppsats har kontaktytorna mellan det sublima och det absurda undersökts utifrån hur Lyotard och Camus definierar respektive begrepp. Uppsatsen har utgått från en forskningssituation där få jämförelser mellan dessa begrepp – som i sig kan te sig undflyende och vaga – verkar finnas. Syftet med undersökningen har således varit att låta nya perspektiv på de båda begreppen träda fram genom deras relation till varandra. Utifrån jämförelsen mellan det sublima och det absurda kan det konstateras att det tycks finnas klara kontaktytor mellan begreppen. Dessa kontaktytor har yttrat sig genom att begreppen delar likheter i följande avseenden: (1) de är båda negativa begrepp, (2) de innefattar liknande kritik mot rationalism, (3) båda begreppen innefattar moment av en för subjektet inledande känsla av hämmande som övergår i en stärkande känsla, (4) de påvisar distansen mellan subjektet och världen, (5) båda innefattar liknande anspråk på konsten som ett slags materialiserad form av deras egen innebörd. Utöver dessa direkta kopplingar uppmärksammades att det Camus kort beskriver som ”känslan av det absurda” kan ses som analogt med det sublima, vilket skulle kunna innebära att den absurda insikten, såsom Camus beskriver den är direkt kopplad till en sublim känsla. Alla dessa aspekter hänger förvisso samman, men det intressanta är att Lyotard och Camus skriver om dem på liknande vis i sina respektive texter. Relationen mellan begreppen kan således uttydas inte endast i generella, utan i specifika likheter.

Culture d'ordre et identités régionales : la gendarmerie dans les départements pyrénéens (1939-1944) / Cultures of order and regional identities : gendarmerie in the Pyrenean departments (1939-1944)

Nativité, Jean-François 02 December 2010 (has links)
Figurant parmi les études pionnières du chantier historique de la Gendarmerie nationale, ce travail s’efforce de revisiter sous l’angle méconnu des départements pyrénéens frontaliers de l’Espagne, la délicate question du rôle des forces de l’ordre durant la Seconde Guerre mondiale. L'interrogation centrale de cette thèse repose sur les bouleversements physiques et psychiques d'une police à statut militaire soumise à différents facteurs déstabilisants. En prenant d'une part comme base initiale la structure spécifique, le cadre juridique, les missions et l'état d'esprit qui constituent l'identité de la gendarmerie d'avant-guerre et d'autre part, le terreau politique, économique et psychologique pyrénéen, l'objectif est de croiser les données endogènes et exogènes liées à la restructuration de l'arme des années quarante, pour obtenir une typologie comportementale capable de répondre à trois types d’interrogations. Tout d’abord, comment les gendarmes stationnés dans les Pyrénées ont-ils vécu la campagne de 1939-1940 et quelle a été leur contribution à l’effort de guerre ? Puis, pendant la période de l’Occupation née de la défaite de la France, alors que la quasi-totalité de l’espace Pyrénéen reste en zone libre jusqu’au mois de novembre 1942, dans quelle mesure les gendarmes locaux ont-ils été concernés par les ordonnances prises par les vainqueurs ? Quelle a été la résultante des transformations voulues par le régime de Vichy et des nouvelles tâches imposées aux gendarmes en poste à la frontière espagnole ? Enfin, dans une région qui s’est longtemps présentée comme un territoire s’étant lui même libéré du joug de l’occupant, comment les gendarmes ont-ils passé le cap de la Libération et du rétablissement de la légalité républicaine ? À la faveur de la soudure symbolique de l’année 1939, la première partie de cette réflexion s’attache à rappeler et à définir la place de la gendarmerie en tant que corps militaire chargé du maintien de l’ordre, dans le contexte socio-historique pyrénéen. Ce bilan de compétences se veut avant tout comme un trait d’union reliant la chaîne des temps et servant de point d’encrage à la compréhension des métamorphoses postérieures. La seconde partie de ce travail est elle dévolue aux « chemins de l’abîme », cette trajectoire événementielle, qui de la chute de Barcelone à l’occupation totale des Pyrénées en novembre 1942, a fait subir à la gendarmerie locale des contorsions réglementaires, fonctionnelles et psychologiques auxquelles elle n’était pas préparée. Enfin pour finir, la dernière partie de cette étude est consacrée à la période allant de l’hiver 1942 à la fin du mois de novembre 1944, qui marque la résurgence et l’indépendance retrouvée de la Gendarmerie nationale. / Appearing among the first studies of the new historical building site of the national Gendarmerie, this work endeavours to revisit under the ignored angle of the frontier Pyrenean departments of Spain, the delicate question of the role of the police force lasting the Second World War. The central interrogation of this PhD rests on the physical and psychic upheavals of a police force with military statute subjected to various destabilizing factors. While taking on the one hand as bases initial the specific structure, the legal framework, the missions and the state of mind which constitute the identity of the gendarmerie of pre-war period and on the other hand, compost political, economic and psychological Pyrenean, the objective is to cross the endogenous and exogenic data related to the reorganization of the weapon of the Forties, to obtain a behavioural typology able to answer three types of interrogations. First of all, how the gendarmes stationed in the Pyrenees did live the countryside of 1939-1940 and which was their contribution to the effort of war ? Then, for the period of the Occupation born of the defeat of France, whereas the near total of Pyrenean space remains in free zone until November 1942, up to what point were the local gendarmes concerned with the ordinances taken by the winners ? Which was the resultant of the transformations wanted by the mode of Vichy and of the new tasks imposed to the gendarmes in post office at the Spanish border ? Lastly, in an area which was presented a long time in the form of a territory being even released to him of the yoke of the occupant, how did the gendarmes pass the course of the Release and the re-establishment of republican legality ? To the favour of the welding symbolic system of the year 1939, the first part of this reflexion attempts to point out and define the place of the gendarmerie as military body in charge of the maintenance of law and order, in the context Pyrenean socio-history. This assessment of competences wants to be before just like a feature of union connecting the chain of times and being used of point of inking for comprehension of the posterior metamorphoses. The second part of this work is it reserved for the "ways of the abyss", this event-driven trajectory, which fall of Barcelona to the total occupation of the Pyrenees in November 1942, subjected the local gendarmerie of the lawful, functional and psychological distortion with which it was not prepared. Finally to finish, the last part of this study is devoted to the period going of the winter 1942 at the end of November 1944, which marks the resurgence and the found independence of the national Gendarmerie.

"L'Ombre de votre espérance" : repères pour une histoire plastique des revues d'artistes expérimentaux au XXe siècle / "Shadow of Hopes" : landmarks For a Plastic History of Experimental Film Journals In the XXth Century

Pierron, Andréa 26 September 2017 (has links)
Cette thèse de doctorat se consacre à l’analyse de périodiques créés au cours du XXe siècle par des cinéastes et des plasticiens à l’œuvre dans le champ des avant-gardes et du cinéma expérimental. Les revues forment des objets plastiques et spéculatifs, complexes et composites de par les relations qui se nouent entre le texte et l’image, les montages qui se créent et le défi que constitue la transposition des images filmiques. En quoi ces revues d’artistes témoignent-elles d’une recherche expérimentale ? Comment les revues d’artistes participent-elles à une histoire critique et plastique des formes cinématographiques ? L’étude tente de comprendre les manières originales dont les cinéastes et les plasticiens se saisissent des revues afin d’élaborer, défendre, documenter, objectiver et analyser certains paradigmes cinématographiques. À quels titres les revues deviennent elles-mêmes des propositions expérimentales, des laboratoires de recherche sur les liens entre l’image et le texte ? Nous observerons comment, grâce à leurs propositions techniques, graphiques et visuelles propres, les revues exposent certains enjeux matériels, poétiques, plastiques et théoriques propres à l’image cinématographique, comment elles questionnent le regard. Les revues offrent des plateformes de diffusion et de dissémination esthétiques, servent à ouvrir des réseaux de circulation pour les idées, singulières ou collectives, des rédacteurs en chef. Comment accompagnent-elles leurs efforts dans la construction d’un milieu cinématographique alternatif ? Les revues Dada I de Tristan Tzara et Hans Arp (1916), Dada Sinn der Welt de John Heartfield et George Grosz (1921), Le Promenoir de Jean Epstein, Pierre Deval et Jean Lacroix (1921-1922), G. für elementare Geschaltung de Hans Richter (1923-1926), Close Up du groupe Pool composé de Kenneth Macpherson, Bryher et H.D. (1927-1933), Film Culture de Jonas Mekas (1955-1996) et Cantrill’s Filmnotes d’Arthur et Corinne Cantrill (1971-2000) forment le corpus de cette thèse qui vise à contribuer à une histoire plastique des publications expérimentales. / This PhD thesis focuses on analyzing periodicals created during the XXth Century by both visual artists and filmmakers operating in the realm of avantgardes and experimental cinema. The journals become plastic, conceptual, complex, and composite objects because of the interplay between text and image as well as the reproduction of images and realization of photomontages. How these artists’ journals show signs of an experimental approach ? How do artists’ journals contribute to the critical and plastic history of film ? The dissertation aims to understand the unique ways the visual artists and filmmakers make use of the journals to create, defend, document, visualize and analyze some cinematic paradigms. To what extent the journals become in turn experimental works about the relationships between text and image ? We will study how magazines exhibit various plastic, aesthetical, theoretical, and poetical dimensions at stake in the cinematic image, relying on specific technical, graphic and visual undertakings, and how they call into question the perception. Journals become instrumentalized in ensuring the movement of the editors’ ideas, either collective or indivuals. How do journals support the editors’ efforts in building an alternative cinema domain ? Dada I edited by Tristan Tzara and Hans Arp (1916), Dada Sinn der Welt by John Heartfield and George Grosz (1921), Le Promenoir by Jean Epstein, Pierre Deval and Jean Lacroix (1921-1922), G. für elementare Geschaltung by Hans Richter (1923-1926), Close Up by Kenneth Macpherson, Bryher and H.D. (1927-1933), Film Culture by Jonas Mekas (1955-1996) and Cantrill’s Filmnotes by Arthur et Corinne Cantrill (1971-2000) form the corpus of this PhD thesis, which aims to contribute to a plastic history of experimental publications.

Le classique chez Julio Ramón Ribeyro : réflexions et inflexions : recherches sur le corpus parafictionnel et la réception de son œuvre / The classic in Julio Ramón Ribeyro : reflections and inflections : Researches on his parafictional corpus and on his work’s reception

Baudry, Paul 14 November 2015 (has links)
Éclipsé par le boom latino-américain dans les années 1960, entre autres à cause d’un certain conservatisme formel, l’écrivain péruvien Julio Ramón Ribeyro (1929-1994) fait partie de ceux qui sont restés en marge de ce phénomène commercial alors que dans son pays d’origine il bénéficie actuellement d’une aura paradigmatique. Nous nous proposons d’analyser ce paradoxe à la lumière du classique en tant que levier conceptuel susceptible de produire une compréhension totalisante et organique aussi bien de la poétique que du destin historique de l’œuvre de Ribeyro. En effet, l’objet de cette thèse est d’étudier, d’abord, les dits et écrits de Ribeyro autour de l’œuvre fictionnelle (journal intime, correspondance, articles, entretiens) qui attestent d’une réflexion sur la possibilité d’une littérature perdurable. Cette pensée articule une dialectique personnelle qui s’achemine de l’avant-garde vers l’arrière-garde au rythme de son rapport fluctuant avec la modernité littéraire. Puis, dans la mesure où le statut classique implique aussi une reconnaissance par des instances de canonisation, nous analysons les supports, les intervenants et les institutions qui ont conditionné sa réception mitigée dans le canon latino-américain ou bien qui ont consolidé sa classicité au Pérou. À cet égard, dans la lignée des études sociocritiques, nous accordons une place de choix aux acteurs officiels (l’État, l’école) et officieux (la critique, les artistes) qui ont contribué ou pas à modeler son image canonique. Finalement, en nous intéressant aux implications idéologiques et ontologiques du classique, nous abordons le rapport individuel et fictionnel de Ribeyro à la tradition comme un héritage social et symbolique qu’il se doit de préserver. / Overshadowed by the Latin American Boom in the 1960s —due to a certain formal conservatism among other reasons— the Peruvian writer Julio Ramón Ribeyro (1929-1994) features among those who remained on the margins of this commercial phenomenon, while in his home country he now enjoys a paradigmatic status. In this thesis we aim to analyze the above paradox in the light of the concept of the classic as a tool enabling to produce a totalizing and organic understanding of both the poetic and the historical outcome of Ribeyro’s work. We propose in first place to review the author’s statements and writings that are peripheral to his fictional work (diaries, correspondence, articles, interviews), which attest to a reflection on the possibility of an everlasting literature. This thinking articulates a personal dialectic that shifts from the avant-garde towards the rearguard, to the rhythm of his fluctuating relationship with literary modernity. In second place, since the classic status implies recognition by the canonization entities, we analyze the array of media, stakeholders and institutions that have conditioned his lukewarm reception in the Latin American canon or that have consolidated his classicity in Peru. Thus, within the scope of sociocritical studies, we give pride of place to the official (government, school) and unofficial stakeholders (critics, artists) who helped or not to shape his canonical image. Finally, by focusing on the ideological and ontological implications of the classic, we address Ribeyro’s personal and fictional interplay with tradition as a social and symbolic heritage that he is compelled to preserve.

Écologie et évolution de la manipulation de type garde du corps : étude du système Dinocampus coccinellae – Coleomegilla maculata / Ecology and evolution of bodyguard manipulation : study of the Dinocampus coccinellae–Coleomegilla maculata model

Maure, Fanny 16 December 2013 (has links)
La manipulation du comportement de l'hôte est une stratégie couramment utilisée chez les organismes parasites, et ce afin de favoriser leur transmission et/ou leur survie. La compréhension d'une telle stratégie est au cœur de plusieurs disciplines appliquées de la parasitologie, telles que l'épidémiologie et la médecine, mais est aussi d'une grande importance d'un point de vue écologique et évolutif. Dans le cadre de cette thèse, notre objectif était d'améliorer l'état des connaissances sur un type de manipulation encore très peu connu : la manipulation garde du corps, une stratégie initialement décrite chez les insectes parasitoïdes. À la suite de leur développement larvaire, certaines guêpes parasitoïdes (Braconidae) ont la capacité d'usurper le comportement de leur hôte et l'obligent ainsi à se comporter comme un véritable garde du corps pour protéger leur cocon des ennemis naturels. Basé sur le système associant la guêpe parasitoïde Dinocampus coccinellae et un de ses hôtes la coccinelle maculée Coleomegilla maculata, le présent travail aborde cinq aspects particuliers de la manipulation parasitaire : i) Efficacité de la protection par un garde du corps et coûts liés à une telle stratégie, ii) Contraintes énergétiques pour les parasites manipulateurs, iii) Diversité et l'évolution de la manipulation garde du corps, iv) Survie des hôtes à la manipulation par un parasitoïde et v) Effets de la nutrition de l'hôte sur une association hôte–parasitoïde manipulateur. Nos résultats apportent plusieurs éléments de réponse quant à l'écologie et l'évolution de la manipulation garde du corps, et notamment en ce qui a trait aux coûts énergétiques associés à une telle stratégie ainsi qu'au rôle de la ressource dans cette étroite association. De nouvelles perspectives de recherche y sont proposées afin d'encourager d'autres travaux dans cette voie. / Host behavioral manipulation, a widespread strategy among parasitic organisms, has evolved to favor the transmission and/or survival of parasites. Understanding such a strategy is at the heart of applied aspects of parasitology, such as epidemiology and medicine, but is also important for evolutionary and ecological reasons. The aim of this study was to improve our knowledge on a category of manipulation that remains poorly documented: the bodyguard manipulation, initially described on parasitoid insects. Following their larval development, certain parasitic wasps (Braconidae) are able to usurp the behavior of their host and force them to serve as bodyguards to protect parasitoid cocoon against natural enemies. Studying the association between the parasitic wasp Dinocampus coccinellae and one of its host the spotted lady beetle Coleomegilla maculata, this work is structured in five axes: i) Efficiency of the bodyguard protection and associated costs, ii) Energetic constraints for manipulative parasites, iii) Diversity and evolution of bodyguard manipulation, iv) Host survival from parasitism and v) Host nutrition effects on a host–manipulative parasitoid association. Our results provide original findings about the ecology and evolution of the bodyguard manipulation, for instance the energetic costs associated with host manipulation or the role of host nutrition in this type of association. New perspectives are identified in order to stimulate future research in this area.
