    Full Text Available The objective of this work was to evaluate 210 Bacillus thuringiensis strains against Aedes aegypti and Culex quinquefasciatus larvae to select the most effective. These strains were isolated from different regions of Brazil and are stored in a Bacillus spp. collection at Embrapa Recursos Genéticos e Biotecnologia, Brasília, Brazil. The selected strains were characterized by morphological (microscopy, biochemical (SDS-PAGE 10% and molecular (PCR methods. Six B. thuringiensis strains were identified as mosquito-toxic after the selective bioassays. None of the strains produced the expected PCR products for detection of cry4, cry11 and cyt1A genes. These results indicate that the activity of mosquitocidal Brazilian strains are not related with Cry4, Cry11 or Cyt proteins, so they could be used as an alternative bioinsecticide against mosquitoes.Neste trabalho foram realizados testes de patogenicidade com 210 estirpes de Bacillus thuringiensis contra larvas de Aedes aegypti e Culex quinquefasciatus, a fim de se determinar as mais eficazes.

A patogenicidade das estirpes não está associada à presença das toxinas Cry4, Cry11 ou Cyt, assim, essas estirpes poderão ser utilizadas para a formatação de um bioinseticida alternativo contra mosquitos.

    Six bioassays were performed to evaluate the efficacy of the fungus, Lagenidium giganteum, against mosquitoes in water collected from 75 sources. The fungus infected larvae of 4 genera and produced greater than 90% mortality in water from some of the creeks, artificial containers and the wild rice field tested during 4 of the assays. There was no larval mortality due to the fungus in water from irrigated pastures or marshes. Water quality parameters associated with L. giganteum infection varied among the bioassays; low measurements of total dissolved solids (TDS), hardness (CaCO3), conductivity, chemical oxygen demand (COD), ammonium nitrogen (NH3-N), phosphate (PO4) and salinity were significantly (P less than 0.05) correlated with fungal efficacy in one or more of the assays. Regression analyses selected TDS, CaCO3, COD, NH3-N and/or PO4 as the best predictors of larval mortality due to L. giganteum. Turbidity and pH were not correlated with fungal efficacy.

Para la evaluación se midió, en condiciones naturales, el porcentaje de reducción de la picadura de los mosquitos o porcentaje de repelencia de varias especies de Anopheles, entre las que se destacan los vectores de malaria An. darlingi, An. nuñeztovari, además de Aedes aegypti y Culex sp. Ambos repelentes mostraron un alto grado de protección que varió en un rango entre 88 a 99% con el repelente tipo jabón y 82 a 100% con el repelente comercial. Existen diferencias estadísticamente significativas (p<0,05 entre los porcentajes de repelencia de los dos repelentes en An. darlingi y todos los anofelinos, pero estas diferencias no tienen importancia práctica puesto que persiste el riesgo de sufrir picaduras con el uso de cualquiera de los dos repelentes. Los resultados indican que ambos repelentes son igualmente efectivos para disminuir el contacto con los mosquitos Anopheles, Culex y Aedes aegypti hasta por 4 horas con una reducción mayor al 80%; pero el repelente tipo jabón tiene un mayor efecto residual hasta al menos 7 horas para los anofelinos. Ninguna persona, de las 14 involucradas en el ensayo, manifestó molestias que pudieran sindicar a los repelentes como los causales.

    Full Text Available As a modern technological invention cinema has numerous potentialities such as economic, social and political power. Fascist regimes as well as film corporations have employed cinema as a tool of propaganda to control and mobilize the masses for the sake of their power longevity. Moreover, the character of film itself is a perfect fascist medium which came from the network of proto-fascism of the twentieth century civilization. By using various genres of Indonesian cinema from different eras as a case study, this article argues that Indonesian propaganda films have monolithic representation which can be described as a cult of "bapakisme" (patronism, "kultur komando" (command culture, marginalisation of women' role in Indonesian revolutionary movement and demonization of progressive women organisation, and glorification of the role of Soeharto in Indonesian revolutionary movement.

  1. Reflections on Music and Propaganda

    Directory of Open Access Journals (Sweden)

    Luis Velasco Pufleau

    2014-01-01

    Full Text Available In general, the concept of propaganda refers to a method as well as the symbolic object mobilized by it. Propaganda equally constitutes a particular type of communication that involves not only the mobilization of objects, but also of discourse, places, acts, and rituals. This essay employs the writings of Max Weber, Paul Ricœur, Jacques Ellul, and Jacques Rancière to analyze propaganda as a particular type of symbolic political dispositif linked to a specific performance and utterance context. I examine humanitarian songs as a propaganda tool in democracy, and show the conditions and the limits of their mobilization through their contextualization. I argue that the link between music and propaganda could be defined as the willingness of a particular power or organized opposition to control the symbolic and emotional dimension of musical works. Through giving the music a meaning in this way, they try to impose a certain social order or to invalidate other possible political configurations of reality. I discuss the contradiction between the specific polysemy of musical works and the fictional construction of reality produced by propaganda, and conclude that the political dimension of music should not necessarily be reduced to the propaganda dispositif. These musical works require consideration of the possibilities offered through fiction in contexts of specific representation, as well as the political dimension of collaborative musical practices.

Another fundamental findings of this study are: First, the existence of a close relationship in which the rulers (government response to be the medium of film as a tool of propaganda with the intent and purpose of the authorities want. So it can be said that propaganda is a conscious, systematic, planned and aimed at concrete. Second, the meaning of propaganda emerging trend is always related to the purpose of the establishment the good and great “image” of ruler. In addition, the propaganda carried on anyway have the intention to attract the sympathy and support of the people, legitimacy, status qou or any form of distortion awareness and conduct establishment version of history “ruler”.

To increase the level of knowledge of the population in this area it is necessary to expand the range of its adequate awareness of tumor diseases. Only joint efforts can limit the destructive effect of cancer on people's minds, so that every person would be responsible for his own health, clearly understanding the advantages of early visit to a doctor. This once again highlights the need of educational work with the public, motivational nature of which allows strengthening the value of screening in the whole complex of measures to fight cancer.

  4. Legal Aspects of Propaganda and Incitement via Satellite

    Science.gov (United States)

    Achilleas, P.

    2002-01-01

    At the beginning of space broadcasting, the use of satellite for propaganda was feared by most countries. Several studies have shown the potential threat of propaganda via satellite. For these reasons, some delegations tried unsuccessfully to include in the 1967 Outer Space Treaty an article prohibiting space propaganda. Finally, under pressure from the Soviet Union and Brazil, the preamble of the 1967 Treaty refers to the 1947 Resolution 110 (II) of the United Nations General Assembly, which condemns propaganda. International law complements the Outer Space Treaty by expressly condemning certain types of propaganda. International law, through several texts condemns war propaganda aimed at provoking armed conflict as well as subversive propaganda aimed at provoking a Coup d'Etat. With the recent war in Afghanistan, the question of war incitement via satellite was invoked in regard to the channel Al Jazzera which was reproached for encouraging conflict and diffusing the words of Osama Ben Laden calling for holy war against the United States. Here again, international law prohibits war incitement. However, the notion of propaganda and war incitement does not lead to an automatic restriction of information since communication via satellite is also protected by freedom of information. Therefore, in all democratic societies, a balance should be made between freedom of information and protection of public order, national security and international peace. Several examples will be taken in order to illustrate this paper, for example of Al Jazzera accused of war and terrorist incitement, Med TV accused by Turkey of subversive Kurdish propaganda and CNN accused by China of defamatory propaganda.

  10. Sludge, biosolids, and the propaganda model of communication.

    Science.gov (United States)

    Rampton, Sheldon

    2002-01-01

    The Water Environment Federation's elaborate effort to rename sewage sludge as "biosolids" is an example in practice of the "propaganda model" of communications, which sees its task as indoctrinating target audiences with ideas favorable to the interests of the communicators. The propaganda model assumes that members of the public are irrational and focuses therefore on symbolic and emotional aspects of communication. This approach to communicating arouses public resentment rather than trust. In place of a "propaganda model," public officials should adopt a "democratic model," which assumes that audiences are rational and intellectually capable of meaningful participation in decision-making.

    Kristina K. Gonzales

    2016-12-01

    Full Text Available Mosquito-borne diseases are responsible for more than a million human deaths every year. Modern mosquito control strategies such as sterile insect technique (SIT, release of insects carrying a dominant lethal (RIDL, population replacement strategies (PR, and Wolbachia-based strategies require the rearing of large numbers of mosquitoes in culture for continuous release over an extended period of time. Anautogenous mosquitoes require essential nutrients for egg production, which they obtain through the acquisition and digestion of a protein-rich blood meal. Therefore, mosquito mass production in laboratories and other facilities relies on vertebrate blood from live animal hosts. However, vertebrate blood is expensive to acquire and hard to store for longer times especially under field conditions. This review discusses older and recent studies that were aimed at the development of artificial diets for mosquitoes in order to replace vertebrate blood.

    Full Text Available Este artigo argumenta que, ao buscar modelos no repertório abolicionista estrangeiro para construir sua propaganda, os abolicionistas brasileiros viram suas possibilidades de escolha restritas pelas oportunidades políticas locais e pela tradição local católica. Contingências que impediram a simples transposição do modelo de ativismo estrangeiro e conduziram a uma atividade criativa de apropriação, em diálogo com o contexto e a tradição brasileiros. Processo que resultou numa reinvenção, uma vez que as artes, sobretudo o teatro, ganharam na propaganda abolicionista brasileira a proeminência que a religião teve na anglo-americana.This article argues that although Brazilian abolitionists turned to foreign models of abolitionism to develop their own propaganda, their choices were constrained by local political opportunities and the local Catholic tradition. Those contingences prevented any simple transposition of a foreign model of activism and led to a creative appropriation that responded to the Brazilian context and tradition. The process eventually turned into a reinvention, since arts, especially the theater, acquired the same prominence in the Brazilian abolitionist propaganda that religion had obtained in Anglo-American countries.

    Full Text Available This Research Paper aims to analyse in depth the global propaganda strategy of the so-called “Islamic State” (IS by looking at the methods through which this grand strategy is carried out as well as the objectives that IS wants to achieve through it. The authors first discuss IS’ growth model, explaining why global expansion and recruitment of foreign fighters are pivotal to IS success. Having in mind this critical role, the authors then explore the narratives and themes used by the group to mobilise foreign fighters and jihadists groups. Third, the paper analyses how IS deploys its narratives in those territories where it has established a foothold. Fourth, it outlines IS’ direct engagement strategy and how it is used to facilitate allegiance of other jihadist groups. The final section of the paper offers a menu of policy options that stakeholders can implement to counter IS’ global propaganda efforts.

    Full Text Available The true battles of the Cold War between the United States and the Soviet Union were fought on the ideological front: pitting democracy and capitalism against totalitarianism and communism. The Office of Policy Coordination (OPC of the Central Intelligence Agency (CIA was formed in the late 1940s to help combat the spread of Communism across Europe and in the United States. Part of the “psychological warfare” included the use of propaganda. Around the same time, British author George Orwell had recently published Animal Farm and Nineteen Eighty-Four. Both novels, due to the anti-Communist overtones, were adopted by the OPC as part of a larger anti-Soviet campaign. By examining the use by intelligence agencies of Orwell’s works during the Cold War and the potential use of those works in a post-9/11 global society, this paper aims to illustrate the fickle nature of literary works as propaganda.

    Mosquitoes carry diseases than can lead to serious illness and death. According to the World Health Organization, mosquitoes infect over 300 million people a year with Malaria and Dengue Fever, two life threatening diseases vectored by mosquitoes. Although insecticides are the most effective way to control mosquitoes, they are not always environmentally friendly. Therefore, alternative tactics should be considered. In this study, we looked at the repellency of various essential oils on female Aedes aegypti through a series of laboratory assays.

  9. Mosquitoes, models, and dengue.

    In the last 10 years dengue has spread markedly through Latin America and the Caribbean (Dominican Republic, Jamaica, Barbados, Mexico, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, Ecuador, Colombia, Venezuela, and Brazil). The mosquito Aedes aegypti has taken advantage of increased urbanization and crowding to transmit the dengue virus. The mosquito infests tires, cans, and water jars near dwellings. The female mosquito practices multiple, interrupted feeding. Thus, mosquito infesting and feeding practices facilitate dengue transmission in crowded conditions. Factors contributing to the spread of dengue include numbers of infected and susceptible human hosts, strain of dengue virus, size of mosquito population, feeding habits, time from infection to ability to transmit virus for both vector and host, likelihood of virus transmission from human to mosquito to human, and temperature (which affects vector distribution, size, feeding habits, and extrinsic incubation period). Public health models may use simulation models to help them plan or evaluate the potential impact of different intervention strategies and/or of environmental changes (e.g., global warming). Other factors contributing to the dengue epidemic are international travel, urbanization, population growth, crowding, poverty, a weakened public health infrastructure, and limited support for sustained disease control programs. Molecular epidemiology by nucleic acid sequence analysis is another sophisticated technique used to study infectious diseases. It showed that dengue type 3 isolated from Panama and Nicaragua in 1994 was identical to that responsible for the major dengue hemorrhagic fever epidemics in Sri Lanka and India in the 1980s. Public health officials must remember three priorities relevant to dengue and other emerging infections: the need to strengthen surveillance efforts, dedicated and sustained involvement in prevention and control needs at the local level, and a strong

    To determine the effectiveness of an index in increasing recognition of misleading problem framing in articles and manuscripts. A propaganda index consisting of 32 items was developed drawing on related literature. Seventeen subjects who review manuscripts for possible publication were requested to read five recent published reports of randomized controlled trials concerning social anxiety and to identify indicators of propaganda (defined as encouraging beliefs and actions with the least thought possible). They then re-read the same five articles using a propaganda index to note instances of propaganda. Convenience sample of individuals who review manuscripts for possible publication and sample of recent published reports of randomized controlled trials regarding social anxiety in five different journals by different authors, blinded by author and journal. Data showed that there was a high rate of propagandistic problem framing in reports of RCTs regarding social anxiety such as hiding well argued alternative views and vagueness. This occurred in 117 out of 160 opportunities over five research reports. A convenience sample of 17 academics spotted only 4.5 percent of propaganda indicators. This increased to 64 percent with use of the 32 item propaganda index. Use of a propaganda index increased recognition of related indicators. However many instances remained undetected. This propaganda index warrants further exploration as a complement to reporting guidelines such as CONSORT and PRISMA.

    The Soviet consultation with its attendant propaganda, visiting nurses, and vacation homes attempted to set science and the doctor as the ultimate authority in matters of child rearing in place of old authorities, deny the contention that motherhood was a natural ability of women, and take over the father's place in the home. Soviet health care policy bridges pre- and postrevolutionary thought, blurred the boundaries between public and private, and mirrored international natalist policies. However, the application of these policies conformed to Soviet concepts of citizens' duties and state imperatives.

  7. Transposable elements in mosquitoes.

    Science.gov (United States)

    Boulesteix, M; Biémont, C

    2005-01-01

    We describe the current state of knowledge about transposable elements (TEs) in different mosquito species. DNA-based elements (class II elements), non-LTR retrotransposons (class I elements), and MITEs (Miniature Inverted Repeat Transposable Elements) are found in the three genera, Anopheles, Aedes and Culex, whereas LTR retrotransposons (class I elements) are found only in Anopheles and Aedes. Mosquitoes were the first insects in which MITEs were reported; they have several LTR retrotransposons belonging to the Pao family, which is distinct from the Gypsy-Ty3 and Copia-Ty1 families. The number of TE copies shows huge variations between classes of TEs within a given species (from 1 to 1000), in sharp contrast to Drosophila, which shows only relatively minor differences in copy number between elements (from 1 to 100). The genomes of these insects therefore display major differences in the amount of TEs and therefore in their structure and global composition. We emphasize the need for more population genetic data about the activity of TEs, their distribution over chromosomes and their frequencies in natural populations of mosquitoes, to further the current attempts to develop a transgenic mosquito unable to transmit malaria that is intended to replace the natural populations.

    Full Text Available O artigo trata das imagens de mulheres e homens velhos na publicidade. Com base em entrevistas, realizadas com os criadores das propagandas, ativistas da questão da velhice e através de uma dinâmica com um grupo da terceira idade, é analisado um corpus de propagandas apresentadas na televisão nos anos 90. O argumento central é que estas imagens são ativas na produção da "reprivatização do envelhecimento", que implica sua transformação num problema dos indivíduos considerados incapazes de se envolver em atividades motivadoras, deixando de adotar formas de consumo e estilos de vida adequados para evitar a velhice.The article deals with images of old men and women in advertising. It analyzes a corpus of TV ads of the 1990's based on interviews with advertising creators, old age activists and a group discussion with a third age activity group. The central argument concerns the fact that those images promote the "reprivatization of aging", which implies transforming it into a problem concerning individuals that are seen as unable to develop motivating skills, and to adopt consumption patterns and ways of life appropriate to avoid old age.

O recorte aqui privilegiado centra-se em propagandas vencedoras de festivais nacionais e em peças veiculadas em revistas de entretenimento. A análise das imagens e dos recursos de linguagem utilizados busca apreender como a propaganda reifica ou desestabiliza noções de gênero e sexualidade percebidas como tradicionais.Although identity can be interpreted in many ways, it has been considered as the core of individual constitution and often seems to interpellate for one's localization in this diverse setting.

The image analysis and language resources used aim to apprehend how advertising reifies or destabilizes gender and sexuality notions taken as traditional.

  15. Pedigrees, propaganda, and paranoia: family studies in a historical context.

    Science.gov (United States)

    Lombardo, P A

    2001-01-01

    This article reviews the uses of family studies carried out in the early 20th century under the banner of eugenics, a companion discipline to early genetics. It explores how, in an attempt to analyze and quantify purportedly biologic bases of social problems, the eugenicists constructed pedigree charts of notoriously "defective" families. Investigation of individuals with suspect traits formed the basis for instruction of field workers who linked those traits to larger groups. The resulting eugenic family studies provided a "scientific" face for a popular hereditarian mythology that claimed to explain all social failure in systematic terms. The eugenicists were successful in fueling public fear about the growing "army of idiots and imbeciles" graphically depicted in their pedigree charts. Their success was the result of a finely crafted educational program--propaganda that reduced science to simplistic terms. The tendency to oversimplify concepts of genetic causation and the rush to amplify the significance of research findings through the popular media is also apparent today. What begins as publicity has the potential to be transformed into propaganda. Although many in the scientific community are understandably reluctant to revisit the abuses of the past, that community must confront the history of eugenics as a necessary antidote to the genetic hype that surrounds us.

    Full Text Available La Colombia colonial regida por virreyes, alcabaleros y frailes, fundó su economía en escasas faenas pastoriles que eran más pasatiempo de nuestros abuelos que correría económica, y en el laboreo de las minas, donde la carne de los negros inflaba las arcas de los chapetones y acrecentaba el afán imperialista de España. Contra los pilones de las rocas hostiles trabajaba una recua importada, que nunca supo de la vida cristiana y cuyo sudor recogían tres o cuatro ciudades antipáticas, encaprichadas en aclimatar las costumbres hispánicas y en gozar de los lujos y prebendas propios de una nación crecida. Hispánicas, fafaracheras y endomingadas nuestras pequeñas ciudades, aparecían en un todo divorciadas de la índole misma del pueblo, de la textura de la Colombia tropical. En esta forma fuimos preparando una línea divisoria entre la ciudad y el campo. Las ciudades progresan, se fundan nuevos pueblos, la conquista se realiza abriendo la selva para plantar moradas y clavar iglesias, mientras que en el campo reina la misma e irremediable soledad. Continúa así la lucha entre la ciudad y el campo, en la cual la primera resulta siempre triunfadora. Toda la riqueza rural está garantizando el progreso y embellecimiento de nuestras urbes, Así la despoblación de los campos no es un hecho tolerado por el país, sino preparado por éste. El traslado patrimonial del campo a la ciudad ha permitido que las clases urbanas se organicen.

  14. Paul Signac's Decorative Propaganda of the 1890s

    Directory of Open Access Journals (Sweden)

    Brion, Katherine

    2012-07-01

    Full Text Available In the 1890s the political and artistic ambitions of the neo-impressionist artist Paul Signac were embodied by a series of decorative projects. This article contends that Signac, inspired by anarcho-communist discourse and the prospect of revolution, attempted to synthesize in these works the didactic logic of propaganda and "purely aesthetic emotion." This synthesis was epitomized by the explicit deployment of two systems, divisionism and decorative pattern. With these systems, Signac hoped to initiate contemporary viewers into the aesthetic and social harmony of an anarcho-communist future. In the interest of addressing larger audiences, particularly among workers, he imagined proletarian spaces for his work. But the didactic elements of Signac's painting met with critical resistance, and public sites he envisioned never materialized. Faced with this lack of recognition, and with a diminished revolutionary outlook in the wake of the Procès des Trente, Signac focused his painting on atemporal landscapes. This trajectory has been read as one of aesthetic liberation; this article seeks to retrieve the extent to which it was also one of constraint, tied to the frustration of Signac's political aspirations.

    Full Text Available The relation between war and cinema, propaganda and cinema is a most intriguing area, located at the intersection of media studies, history and film aesthetics. A truly tragic moment in human history, the First World War was also the first to be fought before film cameras. And while in the field, airborne reconnaissance became cinematic (Virilio, domestic propaganda occupied the screen of the newly emergent national cinemas, only to see its lucid message challenged and even subverted by the fast-evolving language of cinema. Part one of this paper looks at three non-fiction films, released in 1916: Battle of Somme, With Our Heroes at the Somme (Bei unseren Helden an der Somme and Battle of Somme (La Bataille de la Somme, as paradigmatic propaganda takes on the eponymous historical battle from British, German and French points of view. Part two analyses two war-time Hollywood melodramas, David Wark Griffith’s Hearts of the World (1918 and Allen Holubar’s The Heart of Humanity (1919, and explains the longevity of the former with the powerful “text effect” of the authentic wartime footage included. Thus, while these WWI propaganda works do validate Virilio’s ideas of the integral connections between technology, war and cinema, and between cinema and propaganda, they also herald the emancipation of post-WWI film language.

Thus, justification for disintegration of Yugoslavia were provided with main move to accuse Serbs and Serbia for it. Key of such a propaganda could be find in Carl Schmitt's friend-foe dualism which contains moral oppositions good-evil, esthetic beauty-ugly, and economic useful-harmful. Therefore, Serbs in euro-american, especially in german press and other media were represented as evil and ugly ones, thus providing justification for humiliating them on the moral plane. .

    Full Text Available Penelitian ini bertujuan mengungkap bentuk propaganda yang dilakukan oleh pihak kolonial Jepang dalam cerpen “Ave Maria” dan drama empat babak “Kejahatan Membalas Dendam” karya Idrus. Teori yang digunakan untuk mengungkap hal tersebut adalah teori hegemoni Gramsci. Metode yang digunakan dalam penelitian ini adalah metode studi kepustakaan, deskriptif analitik, dan penyajian secara naratif. Hasil analisis menunjukkan bahwa karya Idrus yang ditulis pada masa pendudukan Jepang di Indonesia sarat dengan muatan politis, yaitu politik propaganda yang diterapkan oleh pemerintah Jepang untuk menggelorakan semangat perjuangan rakyat Indonesia. Muatan propaganda yang tercermin dalam karya tersebut adalah agar rakyat Indonesia tidak hanya memikirkan atau mementingkan kepentingan pribadi tetapi juga harus memikirkan atau mementingkan kepentingan bangsa dan agar rakyat Indonesia giat bekerja untuk membantu perjuangan dalam mencapai kemerdekaan nusa dan bangsa, sebagaimana yang telah dijanjikan oleh pemerintah Jepang pada saat memerintah Indonesia. Abstract: In this study, the forms of Japanese propaganda is revealed in Idrus’s short story “Ave Maria” and drama “Kejahatan Membalas Dendam”. Gramsci’s hegemony theory is applied to reveal them. The method used in analyzing the data is descriptive­analytic. The whole research is written in the narrative text. The result of the analysis shows that Idrus’s works written in the Japanese colonization have many of political contents, which was utilized by the Japanese government to spur the Indonesians’ spirit of war. The propaganda contents which were described in the works have the intention that the Indonesians must not only think their personal interest, but also the public interest. Another content is that Indonesian had to work hard to assist Japan in the war with Ally, in order to achieve Indonesian independence, as it had been promised by the Japanese government at the time.

    Full Text Available We tested the use of mosquito traps as an alternative to spraying insecticide in Camargue (France following the significant impacts observed on the non-target fauna through Bti persistence and trophic perturbations. In a village of 600 inhabitants, 16 Techno Bam traps emitting CO2 and using octenol lures were set from April to November 2016. Trap performance was estimated at 70% overall based on mosquitoes landing on human bait in areas with and without traps. The reduction of Ochlerotatus caspius and Oc. detritus, the two species targeted by Bti spraying, was, respectively, 74% and 98%. Traps were less efficient against Anopheles hyrcanus (46%, which was more attracted by lactic acid than octenol lures based on previous tests. Nearly 300,000 mosquitoes from nine species were captured, with large variations among traps, emphasizing that trap performance is also influenced by surrounding factors. Environmental impact, based on the proportion of non-target insects captured, was mostly limited to small chironomids attracted by street lights. The breeding success of a house martin colony was not significantly affected by trap use, in contrast to Bti spraying. Our experiment confirms that the deployment of mosquito traps can offer a cost-effective alternative to Bti spraying for protecting local populations from mosquito nuisance in sensitive natural areas.

Caracterizada normalmente por ataques aos adversários, a utilização de propaganda negativa não representa novidade em eleições majoritárias no Brasil. Contudo, seu estudo retórico e a observação de sua repercussão junto ao eleitor ainda permanecem muito pouco estudados em nosso país. Nossa contribuição aqui é justamente fazer essas análises com base nas eleições presidenciais de 2002, marcadamente um dos pleitos presidenciais recentes que mais veicularam propaganda negativa. Este artigo se divide em 5 partes: 1 - um breve histórico do que é a propaganda negativa; 2 - os fatores que contribuíram para a veiculação da propaganda negativa em 2002; 3 - a repercussão na mídia da propaganda negativa em 2002; 4 - a análise retórica da propaganda negativa e 5 - a repercussão da propaganda negativa junto ao eleitor comum.This present article deals with an object of very common research in foreign literature on Communication Politics, but still less studied in Brazil: the negative ads.

    Full Text Available Producers of Al-Qaeda inspired propaganda have shifted their operations in recent years from closed membership online forums to mainstream social networking platforms. Using social network analysis, we show that behind the apparent proliferation of such sources, YouTube account holders associated with incarnations of the British al-Muhajiroun collude to post propaganda and violent content. European groups commonly use American platforms and domain names registered with American companies. Seeking shelter under speech rights granted by the First Amendment, they evade European laws against incitement and hate speech.

  8. Cyberspace as a new arena for terroristic propaganda: an updated examination.

    Science.gov (United States)

    Minei, Elizabeth; Matusitz, Jonathan

    2012-11-01

    This paper analyzes the role of propaganda use in cyberterrorism. The main premise is that cyberterrorists display various semiotic gestures (e.g., the use of images and Internet videos) to communicate their intents to the public at large. In doing so, they communicate themes-these themes range from hate to anger. Cyberterrorism, then, is a form of theater or spectacle in which terrorists exploit cyberspace to trigger feelings of panic and overreaction in the target population. In many cases, this form of propaganda is the primary means of communication for various cyberterrorist groups to convey their intents. Internet sites also produce numerous opportunities for in-group communication and publicity.

    There is currently renewed interest in assessing the feasibility of the sterile insect technique (SIT) to control African malaria vectors in designated areas. The SIT relies on the sterilization of males before mass release, with sterilization currently being achieved through the use of ionizing radiation. This paper reviews previous work on radiation sterilization of Anopheles mosquitoes. In general, the pupal stage was irradiated due to ease of handling compared to the adult stage. The dose-response curve between the induced sterility and log (dose) was shown to be sigmoid, and there was a marked species difference in radiation sensitivity. Mating competitiveness studies have generally been performed under laboratory conditions. The competitiveness of males irradiated at high doses was relatively poor, but with increasing ratios of sterile males, egg hatch could be lowered effectively. Males irradiated as pupae had a lower competitiveness compared to males irradiated as adults, but the use of partially-sterilizing doses has not been studied extensively. Methods to reduce somatic damage during the irradiation process as well as the use of other agents or techniques to induce sterility are discussed. It is concluded that the optimal radiation dose chosen for insects that are to be released during an SIT programme should ensure a balance between induced sterility of males and their field competitiveness, with competitiveness being determined under (semi-) field conditions. Self-contained 60Co research irradiators remain the most practical irradiators but these are likely to be replaced in the future by a new generation of high output X ray irradiators.

    Claudia Marcela Hernández Cancino

    Full Text Available La enfermedad injerto contra huésped es la principal complicación que sufren los pacientes que han recibido trasplante alogénico. Se produce como consecuencia de una reacción inflamatoria exagerada mediada por los linfocitos del donante y estimulada por aquellos tejidos que han sido lesionados por la enfermedad de base, por las infecciones previas o por el tratamiento de acondicionamiento. El diagnóstico es clínico e histopatológico. Los pacientes presentan rash maculopapular pruriginoso y doloroso que puede extenderse por toda la superficie corporal, fiebre, vómito, náuseas, diarrea y anorexia. En la mucosa bucal se observan erosiones ulceradas, extremamente dolorosas y pueden ser la primera o la única manifestación detectable clínicamente de esta enfermedad. El objetivo es presentar un caso de enfermedad de injerto contra huésped. Se trata de una mujer de 54 años de edad con linfoma no-Hodgking, que recibió tratamiento con quimioterapia, radioterapia y trasplante de células madre hematopoyéticas en el 2009. Tres meses después, presentó lesiones en la piel diagnosticadas como enfermedad injerto contra huésped y tratadas con corticoesteroides, a los seis meses fue remitida al odontólogo porque se quejaba de ardor en la boca, xerostomía y dificultad para masticar, tenía úlceras en la mucosa bucal y en la lengua. En la ocasión recibió tratamiento con corticoesteroides, clorhexidina, orientaciones de higiene bucal y controles clínicos permanentes. Aunque existen protocolos para la prevención y el tratamiento de la enfermedad injerto contra el huésped, su frecuencia ha aumentado en los últimos años debido al incremento en el número de trasplantes. Por esta razón, es fundamental que el odontólogo forme parte del grupo multidisciplinario que asiste al paciente y que esté familiarizado con los signos y síntomas de esta enfermedad en la mucosa bucal, pues las manifestaciones clínicas pueden ser las únicas para

  13. Transgenic mosquitoes and malaria transmission.

    Science.gov (United States)

    Christophides, George K

    2005-03-01

    As the malaria burden persists in most parts of the developing world, the concept of implementation of new strategies such as the use of genetically modified mosquitoes to control the disease continues to gain support. In Africa, which suffers most from malaria, mosquito vector populations are spread almost throughout the entire continent, and the parasite reservoir is big and continuously increasing. Moreover, malaria is transmitted by many species of anophelines with specific seasonal and geographical patterns. Therefore, a well designed, evolutionarily robust and publicly accepted plan aiming at population reduction or replacement is required. The task is twofold: to engineer mosquitoes with a genetic trait that confers resistance to malaria or causes population suppression; and, to drive the new trait through field populations. This review examines these two issues, and describes the groundwork that has been done towards understanding of the complex relation between the parasite and its vector.

    2018-03-08

    Technologies for controlling mosquito vectors based on genetic manipulation and the release of genetically modified mosquitoes (GMMs) are gaining ground. However, concrete epidemiological evidence of their effectiveness, sustainability, and impact on the environment and nontarget species is lacking; no reliable ecological evidence on the potential interactions among GMMs, target populations, and other mosquito species populations exists; and no GMM technology has yet been approved by the WHO Vector Control Advisory Group. Our opinion is that, although GMMs may be considered a promising control tool, more studies are needed to assess their true effectiveness, risks, and benefits. Overall, several lines of evidence must be provided before GMM-based control strategies can be used under the integrated vector management framework. Copyright © 2018 Elsevier Ltd.

    Full Text Available A indústria farmacêutica utiliza a propaganda para a promoção de seus produtos. Os de uso controlado só podem ter a propaganda dirigida a profissionais habilitados a prescrevê-los ou dispensá-los. Este artigo faz uma ampla revisão de artigos científicos que discutem questões éticas e legais acerca da promoção e propaganda de medicamentos em ambientes de ensino médico. Conclui-se que não se justifica a auto-regulamentação da propaganda de medicamentos e que existem evidências suficientes de como o poder da indústria farmacêutica é capaz de influenciar as decisões no âmbito da relação médico-paciente, sendo a promoção e a propaganda um de seus instrumentos. Defende-se sua total proibição em ambientes de ensino, bem como a incorporação da temática na formação dos estudantes. Como a legislação vigente permite a propaganda de medicamentos vendidos sob prescrição apenas a médicos e farmacêuticos, destaca-se que tal propaganda é ilegal quando atinge estudantes de medicina e de farmácia.

    The GLOBE Mosquito Larvae protocol and a new citizen science initiative, GLOBE Observers (GO), were both launched in Summer 2016. While the GLOBE Mosquito Larvae Protocol and associated educational materials target K-16 student inquiry and research, the GO protocol version is simplified to enable citizen scientists of all ages from all walks of life to participate. GO allows citizen scientists to collect and submit environmental data through an easy-to-use smart phone app available for both Apple and Android mobile devices. GO mosquito asks for photos of larvae mosquito genus or species, location, and type of water source (e.g., container or pond) where the larvae were found. To initiate the new mosquito GLOBE/GO opportunities, workshops have been held in Barbuda, Thailand, West Indies, US Gulf Coast, New York City, and at the GLOBE Annual Meeting in Colorado. Through these venues, the protocols have been refined and a field campaign has been initiated so that GO and GLOBE citizen scientists (K-16 students and all others) can contribute data. Quality assurance measures are taken through the online training required to participate and the validation of identification by other citizen sciences and mosquito experts. Furthermore, initial research is underway to develop optical recognition software starting with the species that carry the Zika virus (Aedes aegypti and A. albopictus). With this launch, we plan to move forward by providing opportunities throughout the world to engage people in meaningful environmental and public health data collection and to promote citizen scientists to become agents of change in their communities.

The first section briefly looks at aesthetic theory and addresses the philosophical question of whether war propaganda posters are, in fact, ‘art’ at all. Then images of various posters that were popular and widely published by both nations are shown and discussed. This paper concludes that while there are many thematic similarities between the posters used by both sides, there are also some important differences. The most obvious difference between the German and American propaganda art was in regard to the overall tone of the posters and the colors used in the presentation. The images used have been downloaded from a reputable website that depicts reproductions of the posters that were used during WW1. Understanding the nature of the propaganda used by each side can help shed light on the attitudes and sentiments towards the war held by political elites and citizens alike.

    Full Text Available Mosquito repellants prevent mosquito bites and prevention of "man-mosquito contact" is a critical factor in transmission and spread of any disease through mosquitoes particularly in rural area. There has been a long standing 'bias' towards rural buyers. The rural markets are considered rigid in the nature but it is not the case in real sense. Marketing to rural buyers is not only a challenge to the marketers but to the manufacturers, communicators, national planners and economists as well. That is why it has been necessary to understand the various aspects of selected rural areas and consumption pattern for such a fast growing market i.e. mosquito repellants and rural buyers’ perception towards such urban products. The present paper aims to find out the factors influencing the purchase decisions of rural buyers for mosquito repellants and to study the perceptions of present and potential rural buyers' of selected mosquito repellant brands.

    Las hepatitis virales representan una de las amenazas más importantes para la salud del hombre. Más de 350 millones de personas son portadoras del virus de la hepatitis B (VHB y más de 900 millones han sido infectados alrededor del mundo. En este momento se cuenta con una vacuna recombinante segura y efectiva contra este virus, la cual es producida en células de levadura y contiene el antígeno de superficie del VHB como inmunogeno. En Colombia han recibido la vacuna mas de 5 millones de personas, especialmente menores de 15 años, mientras que en el mundo llega a más de 500 millones de personas. Muchos han sido los países donde la introducción de la vacuna ha llevado a una dramática reducción de los niveles de endemicidad de VHB y entre ellos pueden contarse algunas zonas endémicas de nuestro país. En esos sitios se ha constatado que la prevalencia de la infección y de portadores, se ha reducido en más de un 70% después de la introducción de la vacuna e incluso en Taiwán se ha demostrado ya, una reducción en la incidencia de carcinoma hepatocelular.

    Pese a estos éxitos, algunas características epidemiológicas de la hepatitis B como el alto número de portadores y la posibilidad de transmisión intrauterina, hacen pensar que la eliminación de la infección por VHB está lejos todavía. Adicionalmente hay una proporción de personas, que no desarrolla anticuerpos protectores contra el virus a pesar de recibir un esquema de vacunación adecuado. Debido a ello se ha avanzado en el diseño de vacunas contra VHB mejoradas en su capacidad inmunogénica, tales como vacunas que contienen combinaciones de antígeno de superficie (HBsAg y de otras dos proteínas de la envoltura, las pre S.

    2013-01-01

    Background In 2009, residents of Lhasa city, Tibet Autonomous Region (TAR), China reported large numbers of mosquitoes and bites from these insects. It is unclear whether this was a new phenomenon, which species were involved, and whether these mosquitoes had established themselves in the local circumstances. Methods The present study was undertaken in six urban sites of Chengguan district Lhasa city, Tibet. Adult mosquitoes were collected by bed net trap, labor hour method and light trap in August 2009 and August 2012. The trapped adult mosquitoes were initially counted and identified according to morphological criteria, and a proportion of mosquitoes were examined more closely using a multiplex PCR assay. Results 907 mosquitoes of the Culex pipiens complex were collected in this study. Among them, 595 were females and 312 were males. There was no significant difference in mosquito density monitored by bed net trap and labor hour method in 2009 and 2012. Of 105 mosquitoes identified by multiplex PCR, 36 were pure mosquitoes (34.29%) while 69 were hybrids (65.71%). The same subspecies of Culex pipiens complex were observed by bed net trap, labor hour method and light trap in 2009 and 2012. Conclusion The local Culex pipiens complex comprises the subspecies Cx. pipiens pipiens, Cx. pipiens pallens, Cx. pipiens quinquefasciatus and its hybrids. Mosquitoes in the Cx. pipiens complex, known to be, potentially, vectors of periodic filariasis and encephalitis, are now present from one season to the next, and appear to be established in Lhasa City, TAR.

Herman and Noam Chomsky. The article also analyzes the applicability of the model to other contexts which were not originally contemplated and reflects on other elements which also have the effect of filtering the information and, therefore, should be taken into account by the model. Finally, it considers the possibility of adding two new filters proposed by other authors. The article concludes that the Propaganda Model is even more valid today than it was twenty years ago. It is a very adequate research tool for the analysis of the mass media, but, since it promotes an analysis which is contrary to the interests of the élites, it tends to be institutionally marginalized.Este artículo repasa los cinco elementos (filtros que componen el Modelo de Propaganda y evalúa su relevancia y validez veinte años después de su elaboración original por Edward S.

    In this study, and with a view to extending upon existing findings on the effects of general violent media on violent cognitions, we experimentally measured the relationship between exposure to extremist propaganda and violent cognitions. Our results countered our hypotheses and the wider findings of violent media and aggression that exposure to violent stimuli increases violent thoughts and that this effect is moderated by trait aggression. Specifically, this study found that participants with low and medium trait aggression became more pro-social after being exposed to extremist propaganda. We discuss these results with reference to theories of terror management and mortality salience, as well as the implications of these results for wider theories of the role of online extremist material in the wider "radicalization" process.

    Full Text Available The focus of the present studies is to characterize mosquito net for its material of construction and qualitative as well as quantitative determination of the mosquito repellent chemical deltamethrin present in it. Further, the assessment of the mode of incorporation of the deltamethrin in the fabric of the mosquito net was done, i.e. whether the deltamethrin was present as a coating on the surface of the mosquito net or it was incorporated in the bulk of the material of construction of the mosquito net. The chromatographic technique has been used for quantitative estimation of deltamethrin extracted by two different solvents from the net. It has been found that the determination of deltamethrin in mosquito nets can vary with the method of extraction used. While extraction with acetone is good enough for estimating the chemical adsorbed on the surface, extraction with xylene provides complete information about the chemical present even in the bulk of the material.

    The ambiguity of the role played by British propaganda in Italy during the Second World War is clearly reflected in the phenomenon of Radio London. While Radio London raised the morale of the Italian civilians living under the Fascist regime and provided them with alternative information on the conflict, the microphones of the BBC were also used by the British government to address a country they were planning to occupy.

    Full Text Available Wetlands are valuable habitats that provide important social, economic, and ecological services such as flood control, water quality improvement, carbon sequestration, pollutant removal, and primary/secondary production export to terrestrial and aquatic food chains. There is disagreement about the need for mosquito control in wetlands and about the techniques utilized for mosquito abatement and their impacts upon wetlands ecosystems. Mosquito control in wetlands is a complex issue influenced by numerous factors, including many hard to quantify elements such as human perceptions, cultural predispositions, and political climate. In spite of considerable progress during the last decades, habitat protection and environmentally sound habitat management still remain inextricably tied to politics and economics. Furthermore, the connections are often complex, and occur at several levels, ranging from local businesses and politicians, to national governments and multinational institutions. Education is the key to lasting wetlands conservation. Integrated mosquito abatement strategies incorporate many approaches and practicable options, as described herein, and need to be well-defined, effective, and ecologically and economically sound for the wetland type and for the mosquito species of concern. The approach will certainly differ in response to disease outbreaks caused by mosquito-vectored pathogens versus quality of life issues caused by nuisance-biting mosquitoes. In this contribution, we provide an overview of the ecological setting and context for mosquito control in wetlands, present pertinent information on wetlands mosquitoes, review the mosquito abatement options available for current wetlands managers and mosquito control professionals, and outline some necessary considerations when devising mosquito control strategies. Although the emphasis is on North American wetlands, most of the material is applicable to wetlands everywhere.

    The immune system of many insects wanes dramatically with age, leading to the general prediction that older insects should be more susceptible to infection than their younger counterparts. This prediction is however challenged by numerous studies showing that older insects are more resistant to a range of pathogens. The effect of age on susceptibility to infections is particularly relevant for mosquitoes given their role as vectors of malaria and other diseases. Despite this, the effect of mosquito age on Plasmodium susceptibility has been rarely explored, either experimentally or theoretically. Experiments were carried out using the avian malaria parasite Plasmodium relictum and its natural vector in the field, the mosquito Culex pipiens. Both innate immune responses (number and type of circulating haemocytes) and Plasmodium susceptibility (prevalence and burden) were quantified in seven- and 17-day old females. Whether immunity or Plasmodium susceptibility are modulated by the previous blood feeding history of the mosquito was also investigated. To ensure repeatability, two different experimental blocks were carried out several weeks apart. Haemocyte numbers decrease drastically as the mosquitoes age. Despite this, older mosquitoes are significantly more resistant to a Plasmodium infection than their younger counterparts. Crucially, however, the age effect is entirely reversed when old mosquitoes have taken one previous non-infected blood meal. The results agree with previous studies showing that older insects are often more resistant to infections than younger ones. These results suggest that structural and functional alterations in mosquito physiology with age may be more important than immunity in determining the probability of a Plasmodium infection in old mosquitoes. Possible explanations for why the effect is reversed in blood-fed mosquitoes are discussed. The reversal of the age effect in blood fed mosquitoes implies that age is unlikely to have a

    Full Text Available O objetivo deste estudo foi discutir as propagandas televisivas de medicamentos como forma de transmissão e representação das concepções circulantes sobre saúde, funções e uso de medicamentos. Foi realizada uma análise de conteúdo qualitativa em dez propagandas televisivas, diretas ao consumidor, de medicamentos de comercialização livre no mercado brasileiro, e uma propaganda institucional de uma empresa farmacêutica. Os dados mostraram que a noção que entrelaça as ideias subjacentes às mensagens e as funções do medicamento anunciadas é a de que os "problemas de saúde" advêm de questões corporais, relacionais ou sociais, mas a solução apresentada é individual e consagra-se na compra e no uso do medicamento. A análise sugere, enfim, que noções de saúde e qualidade de vida podem estar marcadas por noções que fundamentam o ideal de saúde atrelado ao consumo.

    Full Text Available O objetivo central do ensaio é tomar como referência os debates travados em torno da regulamentação da publicidade para crianças e adolescentes. Em termos metodológicos, na medida em que se trata de um ensaio teórico, os debates em questão contemplam os pontos de vista da indústria alimentícia, das associações de anunciantes, do Governo e de organismos que representam o consumidor. E são analisados a partir das discussões sobre ética na propaganda, das representações sociais, dos trabalhos que investigam as influências de personagens e de brindes sobre comportamento de compra e da antropologia nutricional. A discussão proposta no ensaio gira em torno das influências das propagandas nas escolhas alimentares do público infanto-juvenil, e a problemática central consiste em ponderar se tais influências são eticamente justificáveis e se os alimentos consumidos trariam riscos para a saúde, como ganho de peso e obesidade. Os resultados encontrados sugerem que as propagandas influenciam as escolhas alimentares e muitas vezes as direcionam para produtos de qualidade nutricional questionável.

    Full Text Available The Chinese Communist Party (CCP government works hard to promote an image of ethnic harmony in China and downplays ethnic conflict by carefully controlling public information and debate about ethnic affairs. Despite such efforts, the recent clashes in Tibetan areas in 2008 and violent riots in Urumqi in 2009 reveal the weaknesses of this approach. This paper surveys the broad themes of ethnic propaganda (民族宣传, minzu xuanchuan in present-day China, looking at the organisations involved, the systems of information management they utilise, and the current “go” and “no-go” zones for debate. The paper forms part of a larger study of the politics of ethnicity in China. It is based on primary- and secondary-source research in Chinese, secondary sources in English, and extensive interviews with Chinese bureaucrats and scholars regarding China’s ethnic affairs conducted during fieldwork in China in 2002, 2004, 2005–2006, 2007, 2009, 2010 and 2012. Ethnic issues in China concern not only the minority peoples there, but also the majority Han – hence, my definition of ethnic propaganda incorporates materials relating to all of China’s ethnic groups. The paper uses the events in Tibetan areas in 2008 and in Urumqi as case studies to demonstrate how these policies play out in periods of crisis. It concludes with a discussion of the role that ethnic propaganda plays in maintaining China’s long-term political stability and its international affairs.

  11. Literature and Propaganda: The Structure of Conversion in Schenzinger's Hitlerjunge Quex

    Directory of Open Access Journals (Sweden)

    John Daniel Stahl

    1988-06-01

    Full Text Available Propaganda literature as a genre can profitably be analyzed by means of a structuralist approach, as Susan R. Suleiman has shown in her study of the French ideological novel. Extending her discussion of the "structure of confrontation" and the "structure of apprenticeship," this study postulates the "structure of conversion" as a fundamental form of propaganda literature. Through loss of self to a greater entity, the central character in fiction exemplifying this form finds a new identity in self-submergence. A once-popular novel by the German pro-fascist author Karl Aloys Schenzinger, Hitlerjunge Quex ( 1932, serves as a model for investigation into the structure of conversion. Religious and psychological dimensions of the central character's experience merge in a representation of conversion that is all the more powerfully ideological for disguising its political and racial assumptions. Eros and Thanatos meet in the mythic heightening of self-sacrifice, culminating in martyrdom. A consideration often ignored by structuralist critics, the use of stylistic means to reinforce implied messages, is shown to be a significant element in Hitlerjunge Quex . The value of a structuralist approach to propaganda lies in its elucidation of hidden assumptions, exposing them to critical judgment.

    2017-03-01

    Full Text Available This paper explores the intersection of sexual and political discourses as a particular aspect of the body politics that Russia has employed, among other strategies, in its massive propaganda offensive during the hybrid warfare against Ukraine.While recognizing sexuality as one of the mainstream concepts in political analysis, the paper draws on sexually explicit imagery and idiom used in Russian social media, and public discursive space in general, as propaganda techniques, and maps their “genealogy” within wider sociocultural and political contexts. Being conceptualized in terms of Russian hegemonic masculinity in relation to subordinated femininity and non-hegemonic masculinities of its adversarial others, these setups reveal how sexuality constitutes uneven and contradictory nexuses of power once being co-opted by Putin’s propaganda machine. It is noteworthy that Russia’s neo-imperial discursive tactics of homologizing sexual and political dominance—when supplemented with the official rhetoric of restituting Russia as a great power, Orthodox Christian fundamentalism as an integral part of Russian unique “state-civilization,” state-sanctioned homophobia, and traditional macho gender ideology—contribute quite effectively to sustaining public support in Russia for aggression against Ukraine in the process of Russian reimperialization of the former Soviet space.

  14. The impact of transgenic mosquitoes on dengue virulence to humans and mosquitoes.

    2009-10-01

    Dengue is a major public health concern in the tropics and subtropics. Innovative transgenic strategies to render Aedes aegypti mosquitoes, the primary vector of dengue, incompetent for dengue transmission are under development. We modeled the evolutionary impact of different transgenic mosquito strategies on dengue-induced mortality, that is, dengue virulence, to both humans and mosquitoes. This model incorporates various evolutionary trade-offs in dengue virus epidemiological traits, for example, a trade-off between dengue transmission rate and its virulence to humans. Our results indicate that strategies that block transmission or reduce mosquito biting impose selection on dengue virulence in humans. This selection can be for either higher or lower virulence, depending on the interaction between the effect of the transgene and the trade-offs in epidemiological traits, highlighting the need for detailed quantitative data to understand more fully the impact of mosquito transgenesis on dengue virulence. Dengue virulence in mosquitoes can be selected on by transgenic strategies of blocking transmission, decreased mosquito biting, increased mosquito background mortality, and increased mosquito infection-induced mortality. Our results suggest that dengue control strategies that raise mosquito background mortality or mosquito infection-induced mortality pose less risk of causing increased virulence to humans than strategies that block transmission or reduce mosquito biting.

    Full Text Available Prints were a remarkable propaganda instrument during the Peninsular War. Since the mid 18th century the State had been encouraging the development of engraving and this favoured the existence of printmakers who satisfied the requirements of the market during these years. This market can be tracked thanks to the advertisements published in the periodical press. Production revolved around satire, portraits and narrative representations. As opposed to these mainly propagandistic prints, Francisco de Goya’s Disasters of War constitute a counterpoint in which the author offers a critical and personal point of view.Las estampas constituyeron un notable instrumento de propaganda durante la Guerra de la Independencia. La labor que el Estado había desarrollado desde mediados del siglo XVIII para el fomento del grabado favoreció la existencia de grabadores que satisficieron la demanda del mercado en estos años.

Sátiras, retratos y representaciones narrativas constituyen los tres ejes alrededor de los que gira esta producción. Frente a estas estampas de función eminentemente propagandística, los Desastres de la guerra de Francisco de Goya constituyen un contrapunto en el que el autor ofrece una visión crítica y personal.

In this study we investigated the toxicological effects of fumes from two locally manufactured mosquito coil insecticides (with pyrethroids: transfluthrin and d-allethrin as active ingredients on male albino rats. For this, we recorded the haematological and biochemical indices, and made histopathology and mutagenicity evaluations in rats exposed to mosquito fumes during 2, 4, 8, 12 and 16 week periods. Haematological determination was performed using automated hematology analyzer to determine White Blood Cell (WBC, Packed Cell Volume (PCV, Red Blood Cell (RBC and Platelet (PLT counts, while biochemical evaluations were determined using available commercial kits. Gross histopathological changes were studied for the kidney, liver and lungs in sacrificed rats. The rat sperm head abnormalities assessment was used to evaluate mutagenicity. Mosquito coil fumes produced significant increase (P0.05. Mutagenicity assessment revealed sperm abnormality was statistically significant (P<0.05 compared with the control at 8, 12 and 16 weeks post exposure to transfluthrin. Histological studies revealed severe lung damage evidenced by interstitial accumulations, pulmonary oedema and emphysema in exposed rats. Intracellular accumulations and severe sinusoidal congestion of liver cells were observed from 12 weeks exposure, indicating liver damage. Our studies indicate that mosquito coil fumes do initiate gradual damage to the host.

    2015-01-01

    Research on parochial altruism demonstrated that hostility toward out-groups (parochialism) represents the dark side of the willingness to benefit one’s in-group even at own costs (altruism). Parochial aggression thereby emerged mainly under conditions of threat. Extremist propaganda videos, for instance by right-wing extremists, try to capitalize on parochial altruistic mechanism by telling recipients sharing their national identity that this nation is under threat wherefore they for have to join the extremist’s cause to prevent the extinction of their nation. Most of the time, propaganda videos are rated as uninteresting and non-persuasive by the target audience. Yet, evolutionary media psychology posits that the interest in and effectiveness of media increases when evolutionarily relevant problems are addressed. Consequently, interest in parochial altruistic right-wing extremist messages should increase under conditions of threat. The current study tested this assumption by randomly assigning German non-Muslims (N = 109) to either an existential threat (here: mortality salience) or a control condition and asking them to evaluate extremist propaganda that addressed them as either in-group members (right-wing extremists) or as out-group members (Islamic extremists). In support of the hypotheses, subjects under conditions of threat reported a higher interest in the right-wing extremist propaganda and perceived it as more persuasive. We discuss the results concerning the implications for evolutionary media psychology and the transmission of parochial altruism in propaganda videos. PMID:26322011

    2013-06-01

    As a geographically isolated island chain with no native mosquitoes, Hawaii is a model for examining the mechanisms behind insect vector invasions and their subsequent interactions with each other and with human populations. The yellow fever mosquito, Aedes aegypti, and the Asian tiger mosquito, Ae. albopictus, have been responsible for epidemics of dengue in Hawaii. As one of the world's earliest locations to be invaded by both species, Hawaii's history is particularly relevant because both species are currently invading new areas worldwide and are implicated in outbreaks of emergent or reemergent pathogens such as dengue, chikungunya, and yellow fever. Here we analyze the historical records of mosquito introductions in order to understand the factors that have led to the current distribution of these 2 mosquitoes in the Hawaiian Islands.

    Mosquito eggs laid within two hours are necessary for transgenic (injection) studies, because mosquito eggs become hard after that period. Thus, in order to have eggs available within this two-hour window, it is important to understand the ovipositional behavior of Anopheles gambiae s.s.. In the present study, the ovipositional behavior of An. gambiae s.s. (Kisumu) was investigated in several different conditions: age of mosquitoes, time post blood meal to access oviposition substrate, and light conditions. Two groups of mosquitoes, 3-5 days old and 9-11 days old were blood-fed. For those mosquito groups, an oviposition dish was set either at 48 hours or 72 hours after the blood meal either in a light condition or in an artificial dark condition. The number of laid eggs was compared among the different conditions. The 3-5 day-old mosquitoes apparently produced a higher number of eggs than 9-11 day-old mosquitoes, while there was no significant difference between the two groups. The number of laid eggs per one surviving blood-fed mosquito in the dark condition was significantly higher than that in the light condition (p = 0.03). Providing an oviposition dish at 72 hours after blood meal resulted in a significantly higher number of laid eggs per one surviving blood-fed mosquito than at 48 hours after blood meal (p = 0.03). In conclusion, the optimal condition to have readily available egg supply for transgenic analysis was as follows: 3-5 day-old mosquitoes with an oviposition dish placed at 72 hours after the blood meal in a dark environment.

    Full Text Available Here, we have used the green method for synthesis of silver and gold nanoparticles. In the present study the silver (Ag and gold (Au nanoparticles (NPs were synthesized by using the aqueous bark extract of Indian spice dalchini (Cinnamomum zeylanicum (C. zyelanicum or C. verum J. Presl. Additionally, we have used these synthesized nanoparticles for mosquito control. The larvicidal activity has been tested against the malaria vector Anopheles stephensi and filariasis vector Culex quinquefasciatus. The results were obtained using UV-visible spectrophotometer and the images were recorded with a transmission electron microscope (TEM. The efficacy tests were then performed at different concentrations and varying numbers of hours by probit analysis. The synthesized AgNPs were in spherical shape and average sizes (11.77 nm AgNPs and 46.48 nm AuNPs. The larvae of An. stephensi were found highly susceptible to the synthesized AgNPs and AuNPs than the Cx. quinquefasciatus. These results suggest that the C. zeylanicum synthesized silver and gold nanoparticles have the potential to be used as an ideal ecofriendly approach for the control of mosquito.

    Com base nas reflexões de Mikhail Bakhtin (1988 sobre cronótopo e nos estudos dos semióticos, principalmente no que tange ao percurso passional do sujeito, analisamos propagandas impressas e comerciais televisivos da Coca-Cola. O objetivo principal é traçar a trajetória discursiva da Coca-Cola desde sua entrada no Brasil, em 1941, até a campanha Gostoso é viver, lançada em 2001. O discurso da Coca-Cola apresenta valores positivos como a alegria, emoção e prazer. Entretanto, são eliminados valores negativos e ocultados interditos, como: Coca-Cola é um produto norte-americano e industrializado, portanto, não é natural, engorda e vicia. Constrói-se, assim, um discurso que privilegia aspectos temáticos voltados para os estados passionais eufóricos (paixão, emoção, alegria. A Coca-Cola também reforça a idéia de que está presente em todo tempo e lugar. Assim, as categorias espaço-temporais são elementos importantes para a construção de sentido de suas propagandas. Reafirmando os mesmos valores e mantendo as categorias cronotópicas para a construção de sentido de suas propagandas, a Coca-Cola consolida a idéia de onipotência, ou seja, ela tem o "poder" de refrescar, trazer alegria, provovar emoção e satisfazer prazeres. Cria-se, assim, um estilo, isto é, uma identidade calcada em categorias divinas, tais como onipresença e onipotência.

    In a connected world where people influence each other, what can cause a globalized monoculture, and which measures help to preserve the coexistence of cultures? Previous research has shown that factors such as homophily, population size, geography, mass media, and type of social influence play important roles. In the present paper, we investigate for the first time the impact that institutions have on cultural diversity. In our first three studies, we extend existing agent-based models and explore the effects of institutional influence and agent loyalty. We find that higher institutional influence increases cultural diversity, while individuals' loyalty to their institutions has a small, preserving effect. In three further studies, we test how bottom-up and top-down processes of institutional influence impact our model. We find that bottom-up democratic practices, such as referenda, tend to produce convergence towards homogeneity, while top-down information dissemination practices, such as propaganda, further increase diversity. In our last model--an integration of bottom-up and top-down processes into a feedback loop of information--we find that when democratic processes are rare, the effects of propaganda are amplified, i.e., more diversity emerges; however, when democratic processes are common, they are able to neutralize or reverse this propaganda effect. Importantly, our models allow for control over the full spectrum of diversity, so that a manipulation of our parameters can result in preferred levels of diversity, which will be useful for the study of other factors in the future. We discuss possible mechanisms behind our results, applications, and implications for political and social sciences.

    Recent reports of Zika virus (ZIKV) isolates from Culex species mosquitoes have resulted in concern regarding a lack of knowledge on the number of competent vector species for ZIKV transmission in the new world. Although observations in the field have demonstrated that ZIKV isolation can be made from Culex species mosquitoes, the detection of ZIKV in these mosquitoes is not proof of their involvement in a ZIKV transmission cycle. Detection may be due to recent feeding on a viremic vertebrate, and is not indicative of replication in the mosquito. In this study, susceptibility of recently colonized Culex species mosquitoes was investigated. The results showed a high degree of refractoriness among members of Culex pipiens complex to ZIKV even when exposed to high-titer bloodmeals. Our finding suggests that the likelihood of Culex species mosquitoes serving as secondary vectors for ZIKV is very low, therefore vector control strategies for ZIKV should remain focused on Aedes species mosquitoes. Our demonstration that Culex quinquefasciatus from Vero Beach, FL, is refractory to infection with ZIKV is especially important and timely. Based on our data, we would conclude that the autochthonous cases of Zika in Florida are not due to transmission by C. quinquefasciatus, and so control efforts should focus on other species, logically Aedes aegypti and Aedes albopictus.

    Full Text Available Mosquitoes act as vectors for a wide range of viral and parasitic infectious diseases such as malaria, dengue, Chickungunya, lymphatic filariasis, Japanese encephalitis and West Nile virus in humans as well as in animals. Although a wide range of insecticides are used to control mosquitoes, it has only resulted in development of resistance to such insecticides. The evolution of insecticide resistance and lack of vaccines for many mosquito-borne diseases have made these arthropods highly harmful vectors. Recently, a novel approach to control mosquitoes by transinfection of life shortening maternally transmitted endo-symbiont Wolbachia wMelPop strain from fruitfly Drosophila into mosquito population has been developed by researchers. The wMelPop strain up-regulated the immune gene expression in mosquitoes thereby reducing the dengue and Chickungunya viral replication in Aedes aegypti, and also it significantly reduced the Plasmodium level in Anopheles gambiae. Here, we discuss the strategy of using Wolbachia in control of vector-borne diseases of mosquitoes.

    Full Text Available A preocupação com a sub-representação do afrodescendente verificada no marketing e em outras manifestações da mídia gera reflexões sociais e acadêmicas. Esta categoria de personagens é presença invariável em papeis subalternos em peças, novelas, filmes e mensagens de propaganda. Tal evidência aponta para estigmas, estereótipos negativos e a transmissão de ideologia racista, explícita ou implícita. No entanto, a literatura, liderada pelo modelo de evolução de Clark (1969 aponta para uma mudança cronológica no tratamento dos afrodescendentes na propaganda e em outras mídias. O objetivo desta pesquisa é analisar o modelo cronológico de representações dos afrodescendentes em propagandas de mídia impressa no Brasil que identifica quatro fases: não reconhecimento, ridicularização, regulamentação e respeito. Esta perspectiva nunca foi aplicada ao caso brasileiro, o que é feito agora. O material de pesquisa é constituído da propaganda veiculada nos jornais Folha de São Paulo e Estado de São Paulo (Estadão, ambos de grande circulação durante três décadas.  Para este tipo de pesquisa as atitudes sociais, em permanente evolução em função de pressões socioeconômicas dos seus principais atores, resultam na aceitação e no respeito às minorias, o que vai se refletir na classificação cronológica proposta. A apreciação crítica dos dados segue a análise de conteúdo de Kassarjian (1976. Os resultados apontam para a inadequação parcial do modelo de Clark ao universo abordado pela pesquisa para o caso brasileiro onde persiste uma eternização do não reconhecimento dos afrodescendentes na mídia impressa.

    Full Text Available In 1944 the Second World War had been raging for more than four long years, with the death toll among soldiers and civilians alike climbing. European Jews constituted a special group of the victims, a fact that leaders of the Allied powers failed to acknowledge. In January 1944 a major revision of previous government policy was brought about in the United States with the establishment of the War Refugee Board in Washington, promising an American commitment to the rescue of European war refugees, including Jews. In March of the same year the situation for Jewish inhabitants in Hungary turned dire as German forces occupied the country. For lack of any other instantly applicable way to influence Hungarian developments, leaders of the new American War Refugee Board decided to launch a propaganda campaign to fight the Nazis and their accomplices. This paper will examine the motivations of American policy makers in focusing on political propaganda measures during the first phase of the Hungarian Holocaust (March–July 1944, and it will describe the logic and workings of the campaign as a means to save Hungary’s Jewry in the last full year of the Second World War.

    The literary perception of venereal diseases in the XIXth century was radically modified by the big prophylactic campaign that began at its end. After writers presented a romantic vision of syphilis associated initially with pride and exaltation, came a generation distressed by the obsession and the phobia that the antivenereal reaction then generated. The moving elements of this campaign, were the extreme attention to overvalued statistics and excessive consideration of indirect transmission; but also such mythical concepts as parasyphilis, syphilitic diathesis, "le génie syphilitique" and especially "hérédosyphilis". This antivenereal campaign, appearing as a sanitary prophylaxis invented by the syphiligraphes, rapidly changed to a moral prophylaxis, using intensively dissuasive methods and generating among others a true propaganda literature. After World War I, the fear of a degeneration of the race, weakened by depopulation, caused an intensification of the propaganda. Its protectionist, xenophobic and intolerant nature then grew considerably in the militant literature to merge into the themes that have characterized the political speech of the Hitlerian period. The Allies and penicillin fortunately put an end to this delirious rhetoric.

  11. Internal-external stimulus competition in a system of interacting moving particles: Persuasion versus propaganda

    2015-07-01

    We propose a general nonlinear analytical framework to study the effect of an external stimulus in the internal state of a population of moving particles. This novel scheme allows us to study a broad range of excitation transport phenomena. In particular, considering social systems, it gives insight of the spatial dynamics influence in the competition between propaganda (mass media) and convincement. By extending the framework presented by Terranova et al. [Europhys. Lett. 105, 30007 (2014), 10.1209/0295-5075/105/30007], we now allow changes in individual's opinions due to a reflection induced by mass media. The equations of the model could be solved numerically, and, for some special cases, it is possible to derive analytical solutions for the steady states. We implement computational simulations for different social and dynamical systems to check the accuracy of our scheme and to study a broader variety of scenarios. In particular, we compare the numerical outcome with the analytical results for two possible real cases, finding a good agreement. From the results, we observe that mass media dominates the opinion state in slow dynamics communities; whereas, for higher agent active speeds, the rate of interactions increases and the opinion state is determined by a competition between propaganda and persuasion. This difference suggests that kinetics can not be neglected in the study of transport of any excitation over a particle system.

    Full Text Available The topic of this paper is the visual propaganda employed in the Empire of Trebizond to convey a sense of the greatness and power of the imperial dynasty of the Grand Komnenoi. The emperors of Trebizond traced their lineage directly back to the famed Komnenian dynasty and saw themselves as the only legitimate successors to Byzantium after its temporary falling-apart, in 1204, as a consequence of the Fourth Crusade. Though only very few images of the emperors of the Grand Komnenoi have been preserved (on chrysobulls, seals, coins, icons, manuscripts, the evidence provided by Medieval authors (Constantine Loukites and Bessarion as well as European travelers and scientists of the 17th-20th centuries (J. Bordier, J.P. Fallmerayer, G. Finlay, F.I. Uspenskij, A. Bryer etc. allows conclusions about the existence of propagandistic portrait images of Trebizond emperors and members of their families in the imperial palace as well as in the most important churches. On the basis of this one may suggest that visual propaganda played an equally important role in Trebizond as in Byzantium. This could be connected with the intention of the Grand Komnenoi to claim their right to the high title of Emperor which, according to the official ideology of Byzantium, only the ruler whose permanent place of residence was Constantinople could possess.

    Full Text Available Mosquito control programs are facing important and timely challenges, including the recent outbreaks of novel arbovirus, the development of resistance in several Culicidae species, and the rapid spreading of highly invasive mosquitoes worldwide. Current control tools mainly rely on the employment of (i synthetic or microbial pesticides, (ii insecticide-treated bed nets, (iii adult repellents, (iv biological control agents against mosquito young instars (mainly fishes, amphibians and copepods (v Sterile Insect Technique (SIT, (vi “boosted SIT”, (vii symbiont-based methods and (viii transgenic mosquitoes. Currently, none of these single strategies is fully successful. Novel eco-friendly strategies to manage mosquito vectors are urgently needed. The plant-mediated fabrication of nanoparticles is advantageous over chemical and physical methods, since it is cheap, single-step, and does not require high pressure, energy, temperature, or the use of highly toxic chemicals. In the latest years, a growing number of plant-borne compounds have been proposed for efficient and rapid extracellular synthesis of metal nanoparticles effective against mosquitoes at very low doses (i.e. 1–30 ppm. In this review, we focused on the promising potential of green-fabricated nanoparticles as toxic agents against mosquito young instars, and as adult oviposition deterrents. Furthermore, we analyzed current evidences about non-target effects of these nanocomposites used for mosquito control, pointing out their moderate acute toxicity for non-target aquatic organisms, absence of genotoxicity at the doses tested against mosquitoes, and the possibility to boost the predation rates of biological control agents against mosquitoes treating the aquatic environment with ultra-low doses (e.g. 1–3 ppm of green-synthesized nanoparticles, which reduce the motility of mosquito larvae. Challenges for future research should shed light on (i the precise mechanism(s of action of

    Research on mosquitoes and mosquito-borne diseases has contributed to improvements in providing effective, efficient, and environmentally proper mosquito control. Florida has benefitted from several research accomplishments that have increased the state’s mosquito control capabilities. Research with Florida’s mosquitoes has resulted in the development of ecologically sound management of mosquito impoundments on Florida’s east coast. This strategy, called Rotational Impoundment Management (RIM), has improved the ability to target the delivery of pesticides and has helped to reduce non-target effects and environmental damage. Research has led to the development of an arbovirus surveillance system which includes sentinel chicken surveillance, real time use of environmental contributing factors like meteorology and hydrology to target mosquito control, as well as public health efforts to mitigate disease outbreaks to areas with risk of disease. These research driven improvements have provided substantial benefits to all of Florida. More research is needed to meet the future challenges to reduce emerging pathogens like Zika virus and the consequences of environmental changes like global climate change that are likely to influence the effects of mosquito-borne pathogens on human health and well-being.

  15. Pond dyes are Culex mosquito oviposition attractants

    2017-05-01

    Full Text Available Background British mosquito population distribution, abundance, species composition and potential for mosquito disease transmission are intimately linked to the physical environment. The presence of ponds and water storage can significantly increase the density of particular mosquito species in the garden. Culex pipiens is the mosquito most commonly found in UK gardens and a potential vector of West Nile Virus WNV, although the current risk of transmission is low. However any factors that significantly change the distribution and population of C. pipiens are likely to impact subsequent risk of disease transmission. Pond dyes are used to control algal growth and improve aesthetics of still water reflecting surrounding planting. However, it is well documented that females of some species of mosquito prefer to lay eggs in dark water and/or containers of different colours and we predict that dyed ponds will be attractive to Culex mosquitoes. Methods Black pond dye was used in oviposition choice tests using wild-caught gravid C. pipiens. Larvae from wild-caught C. pipiens were also reared in the pond dye to determine whether it had any impact on survival. An emergence trap caught any adults that emerged from the water. Water butts (80 L were positioned around university glasshouses and woodland and treated with black pond dye or left undyed. Weekly sampling over a six month period through summer and autumn was performed to quantified numbers of larvae and pupae in each treatment and habitat. Results Gravid female Culex mosquitoes preferred to lay eggs in dyed water. This was highly significant in tests conducted under laboratory conditions and in a semi-field choice test. Despite this, survivorship in black dyed water was significantly reduced compared to undyed water. Seasonal analysis of wild larval and pupal numbers in two habitats with and without dye showed no impact of dye but a significant impact of season and habitat. Mosquitoes were more

    Malaria, dengue and other mosquito-borne diseases pose dramatic problems of public health, particularly in tropical and sub-tropical countries. Historically, vector control has been one of the most successfully strategies to eradicate some mosquito-borne diseases, as witnessed by malaria eradication in Mediterranean regions such as Italy and Greece. Vector control through insecticides has been used worldwide; unfortunately, it is losing effectiveness due to spread of resistances. Control of mosquito-borne diseases through field-releases of genetically engineered mosquitoes is an innovative and now feasible approach. Genetically modified mosquitoes have already been released into the wild in some regions, and protocols for this release are on hand in others. Local authorities are vigilant that transgenic insects in the field are safe for human and animal populations, and the public engagement in every control program is assuming a central role.

  20. Mosquito consumption by insectivorous bats: does size matter?

    Directory of Open Access Journals (Sweden)

    Leroy Gonsalves

    Full Text Available Insectivorous bats have often been touted as biological control for mosquito populations. However, mosquitoes generally represent only a small proportion of bat diet. Given the small size of mosquitoes, restrictions imposed on prey detectability by low frequency echolocation, and variable field metabolic rates (FMR, mosquitoes may not be available to or profitable for all bats. This study investigated whether consumption of mosquitoes was influenced by bat size, which is negatively correlated with echolocation frequency but positively correlated with bat FMR. To assess this, we investigated diets of five eastern Australian bat species (Vespadelus vulturnus Thomas, V. pumilus Gray, Miniopterus australis Tomes, Nyctophilus gouldi Tomes and Chalinolobus gouldii Gray ranging in size from 4-14 g in coastal forest, using molecular analysis of fecal DNA. Abundances of potential mosquito and non-mosquito prey were concurrently measured to provide data on relative prey abundance. Aedes vigilax was locally the most abundant mosquito species, while Lepidoptera the most abundant insect order. A diverse range of prey was detected in bat feces, although members of Lepidoptera dominated, reflecting relative abundance at trap sites. Consumption of mosquitoes was restricted to V. vulturnus and V. pumilus, two smaller sized bats (4 and 4.5 g. Although mosquitoes were not commonly detected in feces of V. pumilus, they were present in feces of 55 % of V. vulturnus individuals. To meet nightly FMR requirements, Vespadelus spp. would need to consume ~600-660 mosquitoes on a mosquito-only diet, or ~160-180 similar sized moths on a moth-only diet. Lower relative profitability of mosquitoes may provide an explanation for the low level of mosquito consumption among these bats and the absence of mosquitoes in feces of larger bats. Smaller sized bats, especially V. vulturnus, are likely to be those most sensitive to reductions in mosquito abundance and should be monitored

    2011-03-01

    We examined the relationship between types of mosquito control programs and the mosquito-borne Ross River virus (RRV) disease in Queensland, Australia. Mosquito control information was collected through a survey of the responsible agencies (local governments), and RRV disease notification data were provided by the Queensland state health authority. The study developed a typology of mosquito control programs, based on the approaches used. Based on the analysis of data on RRV disease rates between mosquito control types within 4 climatic regions, each region had different combinations of mosquito control strategies in their programs; there were also general similarities in the relationship between program types and RRV rates between the regions. The long-term RRV disease rates were lower in areas where the mosquito control program included pre-emptive (rather than reactive) surveillance based on an extensive (rather than incomplete) knowledge of mosquito habitats, and where treatment of both saltwater and freshwater habitats (compared to only saltwater habitats, in coastal areas) occurred. The data indicate that mosquito control is an effective public health intervention to reduce mosquito-borne disease; hence, climate change adaptation strategies should ensure that adequate resources are available for effective vector control so as to manage the risk of mosquito-borne diseases.

    Dengue is the most medically important arthropod-borne viral disease, with 50-100 million cases reported annually worldwide. As no licensed vaccine or dedicated therapy exists for dengue, the most promising strategies to control the disease involve targeting the predominant mosquito vector, Aedes aegypti. However, the current methods to do this are inadequate. Various approaches involving genetically engineered mosquitoes have been proposed, including the release of transgenic sterile males. However, the ability of laboratory-reared, engineered male mosquitoes to effectively compete with wild males in terms of finding and mating with wild females, which is critical to the success of these strategies, has remained untested. We report data from the first open-field trial involving a strain of engineered mosquito. We demonstrated that genetically modified male mosquitoes, released across 10 hectares for a 4-week period, mated successfully with wild females and fertilized their eggs. These findings suggest the feasibility of this technology to control dengue by suppressing field populations of A. aegypti.

    Full Text Available This is a reappraisal of the evidence for the adoption of the later emperor Justinian by his uncle Justin, which has been questioned by Noethlichs (2001. Even though Justinianʼs references to Justin as his ʻfatherʼ are not conclusive, the epigram Anth. Gr. I, 97 can be evaluated as a reliable positive indication. The name ʻJustinianʼ is the original name of the emperor and has nothing to do with the adoption, whereas the names ʻPetrusʼ and ʻSabbatiusʼ as attested in the consular diptychs are secondary names, the former perhaps being a model for the subsequent fashion of devotional cognomina. Finally, the related issues of possible propaganda by Justinian (his comparison to Augustus adopted by Caesar and its reception (by Procopius or John the Lydian are discussed.

    2012-04-01

    Full Text Available "Marking Time" considers the relative scarcity of woman's image in Nazi propaganda posters during World War II. This scarcity departs from the ubiquity of women in paintings and sculptures of the same period. In the fine arts, woman served to solidify the "Nazi myth" and its claim to the timeless time of an Aryan order simultaneously achieved and yet to come. Looking at poster art and using Ernst Bloch's notion of the nonsynchronous, this essay explores the extent to which women as signifiers of the modern – and thus as markers of time – threatened to expose the limits of this Nazi myth especially as the regime's war effort ground to its catastrophic end.

    We introduce a simple model of opinion dynamics in which a two-state agent modified Sznajd model evolves due to the simultaneous action of stochastic driving and a periodic signal. The stochastic effect mimics a social temperature, so the agents may adopt decisions in support for or against some opinion or position, according to a modified Sznajd rule with a varying probability. The external force represents a simplified picture by which society feels the influence of the external effects of propaganda. By means of Monte Carlo simulations we have shown the dynamical interplay between the social condition or mood and the external influence, finding a stochastic resonance-like phenomenon when we depict the noise-to-signal ratio as a function of the social temperature. In addition, we have also studied the effects of the system size and the external signal strength on the opinion formation dynamics.

    Here, we describe the development of the MosqTent, an innovative double-chamber mosquito trap in which a human being attracts mosquitoes while is protected from being bitten within the inner chamber of the trap, while mosquitoes are lured to enter an outer chamber where they are trapped. The MosqTent previously collected an average of 3,000 anophelines/man-hour compared to 240 anophelines/man-hour for the human landing catch (HLC), thereby providing high numbers of human host-seeking mosquitoes while protecting the collector from mosquito bites. The MosqTent performed well by collecting a high number of specimens of Anopheles marajoara, a local vector and anthropophilic mosquito species present in high density, but not so well in collecting An. darlingi, an anthropophilic mosquito species considered the main vector in Brazil but is present in low-density conditions in the area. The HLC showed a higher efficiency in collecting An. darlingi in these low-density conditions. The MosqTent is light (<1 kg), portable (comes as a bag with two handles), flexible (can be used with other attractants), adaptable (can be deployed in a variety of environmental settings and weather conditions), and it can be used in the intra-, peri-, and in the extradomicile. Also, the MosqTent collected similar portions of parous females and anthropophilic mosquito species and collects specimens suitable for downstream analysis. Further developments may include testing for other fabric colors, different mesh sizes and dimensions for other hematophagous insects and conditions, additional chemical mosquito attractants, and even the replacement of the human attractant in favor of other attractants. MosqTent modifications that would allow the trap to be applied as a vector control tool with killing action could also be explored.

Repellents in mustard oil afforded longer protection time against the bites of Aedes (S.) albopictus mosquitoes than those in coconut oil. At 30% concentration, 296-304 min protection time was achieved by the test repellents in mustard oil base while repellents in coconut oil exhibited 223.5-245 min protection time at the same concentration. Oil of Z. limonella gave the highest protection time against the bites of Aedes (S.) albopictus mosquitoes at all the concentrations than other herbal repellents tested both in mustard and coconut oil.

    The 1967 treatment of the Mosquitoes of Colorado by Harmston and Lawson and subsequent publications have recorded 46 culicid species from Colorado. As part of a study to create an updated synopsis of the mosquitoes of Colorado, adult trapping at numerous localities was conducted in Colorado during the summers of 2013 and 2014. This review also included an examination of mosquito specimens in various relevant museum collections. Aedes (Ochlerotatus) niphadopsis and Ae. (Och.) spencerii spencerii were collected during the 2013 and 2014 field seasons. Records for Ae. (Och.) canadensis canadensis, Ae. (Stegomyia) aegypti, and Uranotaenia (Pseudoficalbia) anhydor syntheta were obtained from examination of museum specimens. These species constitute new state records for Colorado, with 51 species now known from the state.

  11. Human to mosquito transmission of dengue viruses

    Full Text Available The successful transmission of dengue virus from a human host to a mosquito vector requires a complex set of factors to align. It is becoming increasingly important to improve our understanding of the parameters that shape the human to mosquito component of the transmission cycle so that vaccines and therapeutic anti-virals can be fully evaluated and epidemiological models refined. Here we describe these factors, and discuss the biological and environmental impacts and demographic changes that are influencing these dynamics. Specifically, we examine features of the human infection required for the mosquito to acquire the virus via natural blood feeding, as well as the biological and environmental factors that influence a mosquito’s susceptibility to infection, up to the point that they are capable of transmitting the virus to a new host.

  15. [Reevaluation of the biological control of vector mosquitoes using predatory larvae of Toxorhynchites mosquitoes].

    Tsukamoto, M; Horio, M

    1985-09-01

    Attempts to control mosquito-borne disease using predatory mosquitoes such as Toxorhynchites larvae have led to indefinite results for many years, mainly because of the lack of adequate species or strains of Toxorhynchites. Recent improvements of natural and artificial matings of adults in the laboratory and of mass breeding of larvae, however, have made it possible to establish laboratory colonies of most Toxorhynchites species whenever and wherever necessary. Effects of biological control by releasing large numbers of Toxorhynchites mosquitoes should be reevaluated from a new concept of comparing the usual chemical insecticides with the living and flying "insecticides" which cause no environmental pollution.

  16. Mosquito infection responses to developing filarial worms.

    Full Text Available Human lymphatic filariasis is a mosquito-vectored disease caused by the nematode parasites Wuchereria bancrofti, Brugia malayi and Brugia timori. These are relatively large roundworms that can cause considerable damage in compatible mosquito vectors. In order to assess how mosquitoes respond to infection in compatible mosquito-filarial worm associations, microarray analysis was used to evaluate transcriptome changes in Aedes aegypti at various times during B. malayi development. Changes in transcript abundance in response to the different stages of B. malayi infection were diverse. At the early stages of midgut and thoracic muscle cell penetration, a greater number of genes were repressed compared to those that were induced (20 vs. 8. The non-feeding, intracellular first-stage larvae elicited few differences, with 4 transcripts showing an increased and 9 a decreased abundance relative to controls. Several cecropin transcripts increased in abundance after parasites molted to second-stage larvae. However, the greatest number of transcripts changed in abundance after larvae molted to third-stage larvae and migrated to the head and proboscis (120 induced, 38 repressed, including a large number of putative, immunity-related genes (approximately 13% of genes with predicted functions. To test whether the innate immune system of mosquitoes was capable of modulating permissiveness to the parasite, we activated the Toll and Imd pathway controlled rel family transcription factors Rel1 and Rel2 (by RNA interference knockdown of the pathway's negative regulators Cactus and Caspar during the early stages of infection with B. malayi. The activation of either of these immune signaling pathways, or knockdown of the Toll pathway, did not affect B. malayi in Ae. aegypti. The possibility of LF parasites evading mosquito immune responses during successful development is discussed.

    Full Text Available Co-occurrence of malaria and filarial worm parasites has been reported, but little is known about the interaction between filarial worm and malaria parasites with the same Anopheles vector. Herein, we present data evaluating the interaction between Wuchereria bancrofti and Anopheles punctulatus in Papua New Guinea (PNG. Our field studies in PNG demonstrated that An. punctulatus utilizes the melanization immune response as a natural mechanism of filarial worm resistance against invading W. bancrofti microfilariae. We then conducted laboratory studies utilizing the mosquitoes Armigeres subalbatus and Aedes aegypti and the parasites Brugia malayi, Brugia pahangi, Dirofilaria immitis, and Plasmodium gallinaceum to evaluate the hypothesis that immune activation and/or development by filarial worms negatively impact Plasmodium development in co-infected mosquitoes. Ar. subalbatus used in this study are natural vectors of P. gallinaceum and B. pahangi and they are naturally refractory to B. malayi (melanization-based refractoriness.Mosquitoes were dissected and Plasmodium development was analyzed six days after blood feeding on either P. gallinaceum alone or after taking a bloodmeal containing both P. gallinaceum and B. malayi or a bloodmeal containing both P. gallinaceum and B. pahangi. There was a significant reduction in the prevalence and mean intensity of Plasmodium infections in two species of mosquito that had dual infections as compared to those mosquitoes that were infected with Plasmodium alone, and was independent of whether the mosquito had a melanization immune response to the filarial worm or not. However, there was no reduction in Plasmodium development when filarial worms were present in the bloodmeal (D. immitis but midgut penetration was absent, suggesting that factors associated with penetration of the midgut by filarial worms likely are responsible for the observed reduction in malaria parasite infections.These results could have an

  18. Genetic Control of Mosquitoes: population suppression strategies

    2012-10-01

    Full Text Available Over the last two decades, morbidity and mortality from malaria and dengue fever among other pathogens are an increasing Public Health problem. The increase in the geographic distribution of vectors is accompanied by the emergence of viruses and diseases in new areas. There are insufficient specific therapeutic drugs available and there are no reliable vaccines for malaria or dengue, although some progress has been achieved, there is still a long way between its development and actual field use. Most mosquito control measures have failed to achieve their goals, mostly because of the mosquito's great reproductive capacity and genomic flexibility. Chemical control is increasingly restricted due to potential human toxicity, mortality in no target organisms, insecticide resistance, and other environmental impacts. Other strategies for mosquito control are desperately needed. The Sterile Insect Technique (SIT is a species-specific and environmentally benign method for insect population suppression, it is based on mass rearing, radiation mediated sterilization, and release of a large number of male insects. Releasing of Insects carrying a dominant lethal gene (RIDL offers a solution to many of the drawbacks of traditional SIT that have limited its application in mosquitoes while maintaining its environmentally friendly and species-specific utility. The self-limiting nature of sterile mosquitoes tends to make the issues related to field use of these somewhat less challenging than for self-spreading systems characteristic of population replacement strategies. They also are closer to field use, so might be appropriate to consider first. The prospect of genetic control methods against mosquito vectored human diseases is rapidly becoming a reality, many decisions will need to be made on a national, regional and international level regarding the biosafety, social, cultural and ethical aspects of the use and deployment of these vector control methods.

  19. Politics or Economics? International Migration during the Nicaraguan Contra War.

    2005-02-01

    The issue of whether Central Americans in the United States are 'political' or 'economic' migrants has been widely debated, yet little empirical research has informed the controversy. Earlier studies have relied primarily on cross-sectional aggregate data. In order to overcome these limitations we draw on recent surveys conducted in five Nicaraguan communities by the Latin American Migration Project. Using retrospective data, we reconstruct a history of a family's migration to the United States and Costa Rica from the date of household formation to the survey date and link these data to national-level data on GDP and Contra War violence. While out migration to both Costa Rica and the United States is predicted by economic trends, US-bound migration was more strongly linked to the level of Contra War violence independent of economic motivations, especially in an interactive model that allows for a higher wartime effect of social networks. We conclude that elevated rates of Nicaraguan migration to the United States during the late 1980s and early 1990s were a direct result of the US-Contra intervention. The approach deployed here - which relates to the timing of migration decisions to macro-level country trends - enables us to address the issue of political versus economic motivations for migration with more precision than prior work.

    2015-01-01

    Full Text Available El 1 de abril de 1939 aparecía el periódico Redención. Se ponía en práctica un nuevo estilo de propaganda destinado a cambiar la imagen de Franco. Desde el comienzo de la guerra, la cultura y el libro se habían convertido en un elemento fundamental en la batalla de las ideas. Se habían sucedido sin cesar las instrucciones para el control y la censura de libros, pero era la primera vez que se experimentaba la creación de un periódico como Redención, consagrado a mostrar la conversión de los propios presos políticos a través de su acceso a la información y la “lectura sana”. El semanario Redención era un producto técnica e ideológicamente pensado y dirigido por los propagandistas católicos, con un fuerte y definido programa cultural que desde el final de la guerra fue potenciado como instrumento dirigido a la conquista de las "minorías selectas", en esta caso, hacia la "intelectualidad roja" para exhibir públicamente su arrepentimiento. Mostrar que en la España de Franco los presos aprendían a leer y escribir, y hasta hacer periódicos, tenía un claro objetivo: suavizar la dura imagen de la represión a la vez que desmitificar la labor pedagógica y el “proyecto cultural” republicanos. Un proceso cultural que se dirigió integralmente hacia el trabajo, la conducta y la instrucción, primaria y religiosa, esto es, hacia la redención de penas por el esfuerzo intelectual

  8. Can transgenic mosquitoes afford the fitness cost?

    2008-01-01

    In a recent study, SM1-transgenic Anopheles stephensi, which are resistant partially to Plasmodium berghei, had higher fitness than non-transgenic mosquitoes when they were maintained on Plasmodium-infected blood. This result should be interpreted cautiously with respect to malaria control using transgenic mosquitoes because, despite the evolutionary advantage conferred by the transgene, a concomitant cost prevents it from invading the entire population. Indeed, for the spread of a resistance transgene in a natural situation, the transgene's fitness cost and the efficacy of the gene drive will be more crucial than any evolutionary advantage.

    Full Text Available The First World War caused a major propaganda battle in Ireland between, on the one hand, the constitutional Nationalist Party, led by John Redmond, and the British authorities who were both in favour of the war and voluntary recruitment, and on the other hand, Sinn Féin, opposition nationalists and also a few Catholic clergymen who were against the British war effort in the country, deeming that the home rule crisis had not been dealt with in a satisfactory way. This article aims at shedding light on the confrontation between the two sides. It seems that the British authorities were rather disorganised in their various propaganda campaigns, while Sinn Fein pursued an energetic and sometimes vitriolic anti-war campaign. One of the themes used by the latter was France’s pre-war anti-clerical policy. This article will consider the extent to which propaganda and “counter-propaganda” influenced voluntary recruitment in Ireland where conscription was not imposed.

    Full Text Available The world depicted in selected novels of the first half of the 1950s functions as a “semantic effect”, precisely shaped by the propaganda of that period. This world is created by narration in order to present the fulfillment of production goals. As a result, we deal with a new reality in which the characters are portrayed first and foremost as manufacturers. Feelings and emotions and their importance are replaced by labor. New civic and social patterns imposed in the novels are to prove that the socialist system is absolutely positive. In order to obtain this goal, primarily lexemes and language constructions are employed, consolidated and repeated in the texts; language conventions that guarantee the coherence of the model of the propaganda-created world. The world presented in the novels set outside Szczecin is narrowed to merely a few thematic fields that are worth discussing.

  18. Nationalism, racism and propaganda in early Weimar Germany: contradictions in the campaign against the "black horror on the Rhine".

    Science.gov (United States)

    Roos, Julia

    2012-01-01

    During the early 1920s, an average of 25,000 colonial soldiers from North Africa, Senegal and Madagascar formed part of the French army of occupation in the Rhineland. The campaign against these troops, which used the racist epithet ‘black horror on the Rhine’ (schwarze Schmach am Rhein), was one of the most important propaganda efforts of the Weimar period. In black horror propaganda, images of alleged sexual violence against Rhenish women and children by African French soldiers served as metaphors for Germany’s ‘victimization’ through the Versailles Treaty. Because the campaign initially gained broad popular and official support, historians have tended to consider the black horror a successful nationalist movement bridging political divides and strengthening the German nation state. In contrast, this essay points to some of the contradictions within the campaign, which often crystallized around conflicts over the nature of effective propaganda. Extreme racist claims about the Rhineland’s alleged ‘mulattoization’ (Mulattisierung) increasingly alienated Rhinelanders and threatened to exacerbate traditional tensions between the predominantly Catholic Rhineland and the central state at a time when Germany’s western borders seemed rather precarious in the light of recent territorial losses and separatist agitation. There was a growing concern that radical strands within the black horror movement were detrimental to the cohesion of the German nation state and to Germany’s positive image abroad, and this was a major reason behind the campaign’s decline after 1921/22. The conflicts within the campaign also point to some hitherto neglected affinities between the black horror and subsequent Nazi propaganda.

  6. Malaria mosquitoes attracted by fatal fungus.

    Directory of Open Access Journals (Sweden)

    Justin George

    Full Text Available Insect-killing fungi such as Beauveria bassiana are being evaluated as possible active ingredients for use in novel biopesticides against mosquito vectors that transmit malaria. Fungal pathogens infect through contact and so applications of spores to surfaces such as walls, nets, or other resting sites provide possible routes to infect mosquitoes in and around domestic dwellings. However, some insects can detect and actively avoid fungal spores to reduce infection risk. If true for mosquitoes, such behavior could render the biopesticide approach ineffective. Here we find that the spores of B. bassiana are highly attractive to females of Anopheles stephensi, a major anopheline mosquito vector of human malaria in Asia. We further find that An. stephensi females are preferentially attracted to dead and dying caterpillars infected with B. bassiana, landing on them and subsequently becoming infected with the fungus. Females are also preferentially attracted to cloth sprayed with oil-formulated B. bassiana spores, with 95% of the attracted females becoming infected after a one-minute visit on the cloth. This is the first report of an insect being attracted to a lethal fungal pathogen. The exact mechanisms involved in this behavior remain unclear. Nonetheless, our results indicate that biopesticidal formulations comprising B. bassiana spores will be conducive to attraction and on-source visitation by malaria vectors.

    Full Text Available Os termos publicidade e propaganda têm sofrido, em anos recentes, de um agravamento na forma indistinta com que são utilizados. Tal fato pode ser analisado dos pontos de vista lingüístico e histórico. Do ponto de vista lingüístico, é perceptível na língua inglesa a presença de três noções que precisam ser ajustadas às duas disponíveis nas línguas latinas em geral. Do ponto de vista histórico, é possível depreender, com base em uma aproximação com as idéias de Jürgen Habermas, que tanto a publicidade de “tornar públicas ações de esfera pública” quanto a de “anunciar transações comerciais” são criações burguesas comprometidas com o racionalismo e com a modernidade, sobrevindas da noção de público e, portanto, características de seu desenvolvimento socioeconômico baseado nas liberdades individuais e no mercado. Palavras-chave: Publicidade; esfera pública; mercado. ABSTRACT The terms publicidade and propaganda have increasingly been used indistinctively in Brazil in recent years. Such fact can be analyzed from linguistic and historical points of view. From the linguistic point of view, the presence of a third concept in the English language usually needs to be adjusted to the two available ones in Latin languages. From the historical point of view, it is possible to infer over a Jürgen Habermas analysis, that both meanings of publicidade – “to make public the actions within thepublic sphere” and “to advertise commercial transactions” – are bourgeois creations implied to rationalism and modernity, in-herited from the notion of “public”. Therefore, it is characteristics of its social-economic development based on individual freedoms and market orientation. Keywords: Publicity; public sphere; market.

    Full Text Available The Cihan-Islam Journal which started its publication life as part of Cemiyet-i Hayriye-i İslamiye (Hayriye-i İslamiye Community was published for propaganda reasons in the pre-First World War period. The Teşkilat-ı Mahsusa which was the intelligence organization of the Ottoman Empire financially supported and directed this journal and was also under the audition of the Ittihadists. The aim of publishing this journal was to raise awareness of the Muslim public living in India, Egypt and Iran which was under the occupation of the British Empire and to prevent the propaganda made against the Ottoman Empire by the British. The owner of this journal was Ebu Saidü’lArabi who was a leading figure among the Indian Muslims and an important person of the Teşkilat- Mahsusa. The journal was published in Istanbul from 9 April 1914 to October 1915. It continued to be published in Bağdat after this peroid. In this study the copies of the journal published in Istanbul have been examined and evaluated. The journal was published once a week starting in April, but as World War 1 broke out it was not published regularly. Only twenty-five copies could be obtained from the archives and libraries in Türkiye. The 25 copies of this journal was examined and evaluated in form and content. The headings of the news and arcticles in the journals have been given in the footnotes and the statistical quantity and evaluation of some of the news and articles have also been done. As a result of the changing policies in the course of the war, the founder and owner of the journal Ebu Said and The Teşkilat-Mahsusa or some Ittihadists had some conflicts of ideas. For this reason, the journal was attempted to be taken out of the hands of Ebu Said but this attempt failed. The journal began to be published in Bağdat starting from January 1916 because of these conflicts. The Uhuvvet Newspaper was published in Istanbul dating from November 1915 to function as this journal.

    Full Text Available Left to fight alone after France signed the armistice on the 22nd of June 1940, Great Britain became enemy number one in the eyes of the German occupying forces and the Vichy government. This hostility found expression in a considerable quantity of propaganda in the guise of posters, tracts, booklets and brochures meant to denounce British responsibility for the conflict in the eyes of French public opinion. Propaganda was particularly intense from June to December 1940 and from January to June 1944 but the German and French propaganda services waged this psychological warfare against Great Britain throughout the war. In 1940, the anti-British brainwashing campaigns aimed at ridding the defeated French of their guilt by accusing the ex-ally of being the cause of the conflict and of deceit during the Battle of France. In 1941-1942, the Allies’ military setbacks were the subject of tracts and brochures that ridiculed British strategic skills. Propaganda was also based on the painful history of France and Great Britain so as to convince the French that England had always tried to deprive France of her colonies and that it was what she was trying to do by maintaining her presence in Africa. The major part of this propaganda was promoted by the German authorities, only to a lesser degree by the French collaboration parties. Till 1942, the Information Secretariat of the Vichy government distributed few anti-British tracts, concentrating its efforts on the promotion of the National Revolution. On the other hand, the first Anglo-American bombings in the Paris area provoked strong reactions in the Vichy government which then relied on the French population’s confusion and anxiety to denounce British policy. What was the impact of these anti-British speeches on the French population? The prefects’ reports on public opinion show that the plugging of Anglophobic sentiment had little influence on the French who were globally in complete support of the

    Full Text Available OBJETIVO: Apresentar uma revisão da literatura sobre a hipótese de que o aleitamento materno teria um efeito protetor contra a obesidade infantil, a plausibilidade biológica dessa hipótese e os mecanismos potencialmente envolvidos. FONTES DOS DADOS: Informações coletadas a partir de artigos publicados em revistas científicas indexadas, livros e teses de pós-graduação. A maioria dos artigos foi identificada a partir das bases de dados MEDLINE e Scielo, usando as palavras-chave "aleitamento materno", "sobrepeso", "obesidade", "crianças" e "adolescentes". O período pesquisado foi de 1980 a 2002. Outros artigos foram identificados a partir das referências bibliográficas citadas nos primeiros artigos. SÍNTESE DOS DADOS: A maioria dos estudos revisados relatou um efeito protetor do aleitamento materno contra a obesidade infantil; alguns estudos não encontraram associação entre aleitamento materno e obesidade; um estudo, com um pequeno tamanho amostral, relatou maior adiposidade entre as crianças que receberam aleitamento materno. Diferentes definições de exposição e desfecho dificultam a comparação entre os estudos. Imprinting metabólico foi sugerido como um mecanismo potencialmente envolvido para explicar a associação. Aspectos comportamentais também podem estar envolvidos. CONCLUSÃO: O aleitamento materno parece ter um efeito protetor contra a obesidade infantil, porém essa questão merece uma investigação mais aprofundada.

  16. Mosquito population regulation and larval source management in heterogeneous environments.

    Directory of Open Access Journals (Sweden)

    David L Smith

    Full Text Available An important question for mosquito population dynamics, mosquito-borne pathogen transmission and vector control is how mosquito populations are regulated. Here we develop simple models with heterogeneity in egg laying patterns and in the responses of larval populations to crowding in aquatic habitats. We use the models to evaluate how such heterogeneity affects mosquito population regulation and the effects of larval source management (LSM. We revisit the notion of a carrying capacity and show how heterogeneity changes our understanding of density dependence and the outcome of LSM. Crowding in and productivity of aquatic habitats is highly uneven unless egg-laying distributions are fine-tuned to match the distribution of habitats' carrying capacities. LSM reduces mosquito population density linearly with coverage if adult mosquitoes avoid laying eggs in treated habitats, but quadratically if eggs are laid in treated habitats and the effort is therefore wasted (i.e., treating 50% of habitat reduces mosquito density by approximately 75%. Unsurprisingly, targeting (i.e. treating a subset of the most productive pools gives much larger reductions for similar coverage, but with poor targeting, increasing coverage could increase adult mosquito population densities if eggs are laid in higher capacity habitats. Our analysis suggests that, in some contexts, LSM models that accounts for heterogeneity in production of adult mosquitoes provide theoretical support for pursuing mosquito-borne disease prevention through strategic and repeated application of modern larvicides.

  17. Paratransgenesis: a promising new strategy for mosquito vector control.

    The three main mosquito genera, Anopheles, Aedes and Culex, transmit respectively malaria, dengue and lymphatic filariasis. Current mosquito control strategies have proved unsuccessful, and there still is a substantial number of morbidity and mortality from these diseases. Genetic control methods have now arisen as promising alternative strategies, based on two approaches: the replacement of a vector population by disease-refractory mosquitoes and the release of mosquitoes carrying a lethal gene to suppress target populations. However, substantial hurdles and limitations need to be overcome if these methods are to be used successfully, the most significant being that a transgenic mosquito strain is required for every target species, making genetically modified mosquito strategies inviable when there are multiple vector mosquitoes in the same area. Genetically modified bacteria capable of colonizing a wide range of mosquito species may be a solution to this problem and another option for the control of these diseases. In the paratransgenic approach, symbiotic bacteria are genetically modified and reintroduced in mosquitoes, where they express effector molecules. For this approach to be used in practice, however, requires a better understanding of mosquito microbiota and that symbiotic bacteria and effector molecules be identified. Paratransgenesis could prove very useful in mosquito species that are inherently difficult to transform or in sibling species complexes. In this approach, a genetic modified bacteria can act by: (a) causing pathogenic effects in the host; (b) interfering with the host's reproduction; (c) reducing the vector's competence; and (d) interfering with oogenesis and embryogenesis. It is a much more flexible and adaptable approach than the use of genetically modified mosquitoes because effector molecules and symbiotic bacteria can be replaced if they do not achieve the desired result. Paratransgenesis may therefore become an important integrated

    Full Text Available Demonization of Germans was an early feature of British propaganda in World War I, with numerous atrocities reported in the Bryce Report, 1915. But in April, 1917, a particularly gripping, gruesome, and odium-inducing tale was given credence by the press of Lord Northcliffe, notably The Times and The Daily Mail.These papers seemed to provide convincing proof that the Germans boiled down corpses of their own soldiers for the purpose of producing useful products such as fats, bone meal, pig food and the like. The story is well known, but significant details have been obscured or misrepresented with regard to the way in which it came to be so widely believed. Our purpose here is to straighten out key elements of the record, based on archival findings, and to draw attention to the techniques employed to ensure widespread credence in this false tale. These techniques, and the principles behind their use, have recent and contemporary parallels, some of which are drawn in this paper. The Corpse Factory story succeeded in its goal, but may have made a lasting peace more difficult. Also, official repudiation of the story in 1925 encouraged later disbelief when early reports circulated about the Holocaust under Hitler, thus contributing to the early lack of response by nations asked to accept Jewish refugees.

    Full Text Available Production, distribution, and consumption of cinematic violence raises several questions of academic import. Despite a plethora of research studies exploring the nature of screen violence and its effects on viewers, a serious debate on the influence of state machinery on the production of sanitized violence in movies is still wanting. Likewise, Bollywood’s role in advancing the Indian government’s agenda in war and peace times has been paid petite attention in academic discourses dealing with media-state interconnection. This article explores the relevance of Herman and Chomsky’s propaganda model as a framework for analysis and analyzes Bollywood’s movies based on stories of violence in war and peace times. The article discusses the connections with the Indian state apparatus that influences production processes in the Indian film industry by providing financial assistance and applying multifarious political, social, economic, and ideological pressures (filters. The findings suggest that the Bollywood movies support diplomatic initiatives of the Indian government through cinematic narratives of sanitized violence.

    Full Text Available The noise produced by a contra-rotating ventilator can cause injury to humans. Therefore, it is important to reduce noise caused by ventilators. In this study, the Ffowcs Williams and Hawkings (FW-H model was used to simulate the acoustics of four different axial impeller spacing points based on the unsteady flow field through a FBD No. 8.0 contra-rotating ventilator. Experiments were conducted to verify the correctness of the numerical model. Meanwhile, the Variable Frequency Drive (VFD drives the two motors of 55 kW to give the impellers different speeds to distinguish different conditions. The results showed that the main noise source of the ventilator was the two rotating impellers and the area between them. For the same axial space, the noise decreased with the increase of flow rate and then decreased. And the amplitude of the discrete pulse increased gradually. It can be concluded that the vortex acoustics decreased gradually with the increase of flow rate and the rotating acoustics were the major contributor. With the axial distance increasing, the noise caused by the two impellers was weak, and the frequencies of sound pressure level moved toward medium- and low-frequency bands gradually. The suitable axial space could reduce noise and improve the working environment.

El lenguaje cinematográfico y la representación fílmica de esa contienda forman un ámbito relevante en el que estudiar algunos rasgos de la matriz cultural europea. El presente trabajo selecciona parte de la producción fílmica de propaganda del gobierno republicano, en concreto los filmes de montaje supervisados por Luis Buñuel. Al inicio de la contienda el cineasta aragonés vuelve a París siguiendo las indicaciones del Ministerio español de Asuntos Exteriores para colaborar, en la embajada española en la capital francesa, en diversas labores de contraespionaje y propaganda. Entre ellas y principalmente, Buñuel se ocupa de reunir, organizar y montar diverso material fílmico prorrepublicano. A diferencia de otras producciones proyectadas en España, los filmes parisinos de propaganda republicana se caracterizaron, en términos generales, por estar dirigidas a públicos de distintos países europeos con el objetivo de romper la doctrina de no intervención en el conflicto y se inscriben dentro de las teorías y concepción de Buñuel sobre el documentalismo filmado, donde primaba lo reflexivo y los recursos psicológicos que motivaran a la acción o a la toma de conciencia individual. El presente texto se ocupa, en ese contexto, de la descripción y el análisis del lenguaje y las prácticas fílmicas en esos años.

  10. Optimal control strategy of malaria vector using genetically modified mosquitoes.

    2009-06-07

    The development of transgenic mosquitoes that are resistant to diseases may provide a new and effective weapon of diseases control. Such an approach relies on transgenic mosquitoes being able to survive and compete with wild-type populations. These transgenic mosquitoes carry a specific code that inhibits the plasmodium evolution in its organism. It is said that this characteristic is hereditary and consequently the disease fades away after some time. Once transgenic mosquitoes are released, interactions between the two populations and inter-specific mating between the two types of mosquitoes take place. We present a mathematical model that considers the generation overlapping and variable environment factors. Based on this continuous model, the malaria vector control is formulated and solved as an optimal control problem, indicating how genetically modified mosquitoes should be introduced in the environment. Numerical simulations show the effectiveness of the proposed control.

    Full Text Available Abstract Backgrond In the mosquito Aedes aegypti the insulin/insulin growth factor I signaling (IIS cascade is a key regulator of many physiological processes, including reproduction. Two important reproductive events, steroidogenesis in the ovary and yolk synthesis in the fat body, are regulated by the IIS cascade in mosquitoes. The signaling molecule phosphatase and tensin homolog (PTEN is a key inhibitor of the IIS cascade that helps modulate the activity of the IIS cascade. In Ae. aegypti, six unique splice variants of AaegPTEN were previously identified, but the role of these splice variants, particularly AaegPTEN3 and 6, were unknown. Results Knockdown of AaegPTEN or its specific splice variant AaegPTEN6 (the splice variant thought to regulate reproduction in the ovary and fat body using RNAi led to a 15–63% increase in egg production with no adverse effects on egg viability during the first reproductive cycle. Knockdown of AaegPTEN3, expressed predominantly in the head, had no effect on reproduction. We also characterized the protein expression patterns of these two splice variants during development and in various tissues during a reproductive cycle. Conclusion Previous studies in a range of organisms, including Drosophila melanogaster and Caenorhabditis elegans, have demonstrated that disruption of the IIS cascade leads to decreased reproduction or sterility. In this study we demonstrate that knockdown of the IIS inhibitor PTEN can actually increase reproduction in the mosquito, at least during the first reproductive cycle.

    To test whether Zika virus has adapted for more efficient transmission by Aedes aegypti mosquitoes, leading to recent urban outbreaks, we fed mosquitoes from Brazil, the Dominican Republic, and the United States artificial blood meals containing 1 of 3 Zika virus strains (Senegal, Cambodia, Mexico) and monitored infection, dissemination, and virus in saliva. Contrary to our hypothesis, Cambodia and Mexica strains were less infectious than the Senegal strain. Only mosquitoes from the Dominican...

    Yellow fever mosquito Aedes aegypti transmits many devastating arthropod-borne viruses (arboviruses), such as dengue virus, yellow fever virus, Chikungunya virus, and Zika virus, which cause great concern to human health. Mosquito control is an effective method to block the spread of infectious diseases. Ae. aegypti uses its innate immune system to fight against arboviruses, parasites, and fungi. In this review, we briefly summarize the recent findings in the immune response of Ae. aegypti against arboviral and entomopathogenic infections. This review enriches our understanding of the mosquito immune system and provides evidence to support the development of novel mosquito control strategies. Copyright © 2017 Elsevier Ltd.

    Full Text Available Zika virus is a newly emergent mosquito-borne flavivirus that has caused recent large outbreaks in the new world, leading to dramatic increases in serious disease pathology including Guillain-Barre syndrome, newborn microcephaly, and infant brain damage. Although Aedes mosquitoes are thought to be the primary mosquito species driving infection, the virus has been isolated from dozens of mosquito species, including Culex and Anopheles species, and we lack a thorough understanding of which mosquito species to target for vector control. We exposed Anopheles gambiae, Anopheles stephensi, and Culex quinquefasciatus mosquitoes to blood meals supplemented with two Zika virus strains. Mosquito bodies, legs, and saliva were collected five, seven, and 14 days post blood meal and tested for infectious virus by plaque assay. Regardless of titer, virus strain, or timepoint, Anopheles gambiae, Anopheles stephensi, and Culex quinquefasciatus mosquitoes were refractory to Zika virus infection. We conclude that Anopheles gambiae, Anopheles stephensi, and Culex quinquefasciatus mosquitoes likely do not contribute significantly to Zika virus transmission to humans. However, future studies should continue to explore the potential for other novel potential vectors to transmit the virus.

    Full Text Available Culex quinquefasciatus mosquitoes have been successfully genetically modified only once, despite the efforts of several laboratories to transform and establish a stable strain. We have developed a transient gene expression method, in Culex, that delivers plasmid DNA directly to the mosquito haemolymph and additional tissues. We were able to express DsRed2 fluorescent protein in adult Cx. quinquefasciatus mosquitoes by injecting plasmids directly into their thorax. The expression of DsRed2 in adult Cx. quinquefasciatus mosquitoes is an important stepping stone to genetic transformation and the potential use of new control strategies and genetic interactions.

    Full Text Available A publicidade é uma ferramenta legítima e não é um problema, se os objetivos comerciais não ultrapassarem os limites éticos. As propagandas de medicamentos no Brasil já eram produzidas desde 1911 e promoviam a venda de medicamentos “mais ou menos” explicitamente. Entretanto, medicamentos são produtos especiais, cujas peças publicitárias requerem cuidados diferenciados no que tange os aspectos éticos e morais. O estudo objetivou investigar quais são e quantificar os ilícitos cometidos em propagandas de medicamentos veiculadas em TV Aberta para o grande público do Distrito Federal e cidades que o circundam, chamadas “Região do Entorno”. No estudo observacional, transversal e descritivo, foram monitoradas 56 propagandas, em 14h de programação, entre março de 2012 a março de 2013. A análise legal da monitoração de 40 peças incluídas na amostragem ocorreu sob a égide da Resolução de Diretoria Colegiada RDC Nº 96/2008 da Anvisa. Os resultados evidenciaram que em 100% das peças publicitárias ocorreram infrações à legislação. Em média, houve infração de quatro artigos da RDC por propaganda e no total foram sete os artigos ignorados da Legislação Sanitária. Em consonância com a literatura, os analgésicos, antigripais, anti-inflamatórios e antiácidos foram os mais divulgados. A ausência de informação sobre os cuidados/advertências, no uso, pode indicar que o medicamento seja totalmente seguro e eficaz, o que induz ao risco sanitário da automedicação irresponsável, que tem se tornado um problema de saúde pública mundial.

    We present the design, analysis, and experimental characterization of a novel integrated add-drop filter capable of filtering simultaneously two independent channels that is based on a contra-directional grating assisted coupler with two different periods. The device performance is explained using Fourier analysis and confirmed with numerical simulations using the eigenmode expansion method. The devices were fabricated using electron-beam lithography on a silicon-on-insulator wafer with a 220 nm thick device layer. The Fourier analysis, simulations and experimental results are in agreement and show that the drop port response of the two-period configuration is the superposition of the drop port responses of two single-period gratings. Therefore, the output channels at drop port can be designed independently and can have different bandwidths.

    2015-10-01

    Hematophagous arthropods and the diseases associated with them represent a growing threat to human and animal health in Europe. After the eradication of endemic malaria from Europe in the middle of the last century, there has been a resurgence of mosquitoes as significant vectors of disease agents under the influence of continuing globalisation, as exotic species and mosquito-borne pathogens are being introduced with increasing frequency. At present, southern Europe is particularly affected by disease outbreaks and cases, but invasive mosquito species, including efficient vectors, have also emerged in Germany. While there is considerable knowledge on the vector potential of many tropical and subtropical mosquito species, corresponding data on the indigenous mosquito species are scarce. Exceptions are the Anopheles species, which were already vectors of malaria parasites in historic Europe. It must be assumed, however, that many further indigenous species are able to transmit pathogens under certain conditions and will by all means gain vector competence under a scenario of climate warming. Thus, the permanent surveillance of mosquitoes and mosquito-borne disease agents is paramount for the purposes of conducting risk analyses and modelling, in addition to research work addressing the conditions of the spread of vectors and pathogens and of pathogen transmission. Only ample data can facilitate taking appropriate prophylactic action and designing control strategies. International health organizations have realised this and started to promote data collection on mosquitoes and mosquito-borne diseases in the EU. At a national levels, authorities are more reluctant, although, similar to other fields of health, it has been shown for mosquito-borne diseases that preventive measures are more cost-saving than disease case management and the coverage of follow-up costs. The present article is intended to illustrate the necessity of the re-intensification of mosquito

    Integrated mosquito control is expensive and resource intensive, and changing climatic factors are predicted to expand the habitable range of disease-carrying mosquitoes into new regions in the United States. Of particular concern in the northeastern United States are aedes albopictus, an aggressive, invasive species of mosquito that can transmit both native and exotic disease. Ae. albopictus prefer to live near human populations and breed in artificial containers with as little as two millimeters of standing water, exponentially increasing the difficulty of source control in suburban and urban areas. However, low-cost unmanned aerial vehicles (UAVs) can be used to photograph large regions at centimeter-resolution, and can image containers of interest in suburban neighborhoods. While proofs-of-concepts have been shown using UAVs to identify naturally occurring bodies of water, they have not been used to identify mosquito habitat in more populated areas. One of the primary challenges is that post-processing high-resolution aerial imagery is still time intensive, often labelled by hand or with programs built for satellite imagery. Artificial neural networks have been highly successful at image recognition tasks; in the past five years, convolutional neural networks (CNN) have surpassed or aided trained humans in identification of skin cancer, agricultural crops, and poverty levels from satellite imagery. MosquitoNet, a dual classifier built from the Single Shot Multibox Detector and VGG16 architectures, was trained on UAV­­­­­ aerial imagery taken during a larval study in Westchester County in southern New York State in July and August 2017. MosquitoNet was designed to assess the habitat risk of suburban properties by automating the identification and counting of containers like tires, toys, garbage bins, flower pots, etc. The SSD-based architecture marked small containers and other habitat indicators while the VGG16-based architecture classified the type of

    Mosquito-borne pathogens pose major public health challenges worldwide. With vaccines or effective drugs still unavailable for most such pathogens, disease prevention heavily relies on vector control. To date, however, mosquito control has proven difficult, with low breeding-site coverage during control campaigns identified as a major drawback. A novel tactic exploits the egg-laying behavior of mosquitoes to have them disseminate tiny particles of a potent larvicide, pyriproxyfen (PPF), from resting to breeding sites, thus improving coverage. This approach has yielded promising results at small spatial scales, but its wider applicability remains unclear. We conducted a four-month trial within a 20-month study to investigate mosquito-driven dissemination of PPF dust-particles from 100 'dissemination stations' (DSs) deployed in a 7-ha sub-area to surveillance dwellings and sentinel breeding sites (SBSs) distributed over an urban neighborhood of about 50 ha. We assessed the impact of the trial by measuring juvenile mosquito mortality and adult mosquito emergence in each SBS-month. Using data from 1,075 dwelling-months, 2,988 SBS-months, and 29,922 individual mosquitoes, we show that mosquito-disseminated PPF yielded high coverage of dwellings (up to 100%) and SBSs (up to 94.3%). Juvenile mosquito mortality in SBSs (about 4% at baseline) increased by over one order of magnitude during PPF dissemination (about 75%). This led to a >10-fold decrease of adult mosquito emergence from SBSs, from approximately 1,000-3,000 adults/month before to about 100 adults/month during PPF dissemination. By expanding breeding-site coverage and boosting juvenile mosquito mortality, a strategy based on mosquito-disseminated PPF has potential to substantially enhance mosquito control. Sharp declines in adult mosquito emergence can lower vector/host ratios, reducing the risk of disease outbreaks. This approach is a very promising complement to current and novel mosquito control strategies

    Full Text Available The article analyses the linguistic and discursive processes implemented by the online magazine Sala@m in order to build a certain representation of the Muslim community in Great Britain. We consider the magazine’s discourse as an example of propaganda speech, the aim of which is to influence the audience by summoning up both its reason and affect. The notion of “narrative identity” (Ricoeur is essential to our analysis, for it enables us to highlight the system of narration which the magazine uses to create a collective story that it endeavours to tell the targeted audience. This narrative identity is meant to work as a mirror so that the audience recognizes itself in it and finds both a valued and clearly different image of the British Muslim community. The narrative identity elaborated in the magazine aims at turning a set of individuals into a homogeneous group endowed with consistency and temporal unity and which may consequently take position in the public space and claim rights on behalf of a marginalized group. We take an interest in the selective nature of the elaboration of the narrative identity, in what Ricoeur calls the configuration and reconfiguration, so as to enhance the work of selection that is specific to the propaganda speech of Sala@m.

    2017-01-01

    Full Text Available The Communist regime installed in Romania with the support of the Soviet army set out on a large-scale propaganda mission to implement the new ideology, backed up by new legislation. Children were one of the targeted age groups, and the strategies of indoctrination adopted confirmed that the Soviets had advanced knowledge concerning the stages of children’s cognitive development. Some of the most effective instruments in creating the «new man» were the periodicals dedicated to children, which were actually press organs of the Romanian Communist Party. However, this detail was ignored by most parents, and thought irrelevant to the children’s universe. A number of other factors secured the success of this means of propaganda: the trust and appreciation of these publications among children, an excellent distribution network, low acquisition cost, the limited number of books available, and reduced access to the same. In an era dominated by austerity in terms of communication and forms of entertainment, children’s periodicals represented an escape from the poverty and banality of everyday life.

    The ability to manipulate the mosquito genome through germ-line transformation provides us with a powerful tool for investigating gene structure and function. It is also a valuable method for the development of novel approaches to combating the spread of mosquito-vectored diseases. To date, germ-line transformation has been demonstrated in several mosquito species. Transgenes are introduced into pre-blastocyst mosquito embryos using microinjection techniques that take a few hours, and progeny are screened for the presence of a marker gene. The microinjection protocol presented here can be applied to most mosquitoes and contains several improvements over other published methods that increase the survival of injected embryos and, therefore, the number of transformants. Transgenic lines can be established in approximately 1 month using this technique.

    To test whether Zika virus has adapted for more efficient transmission by Aedes aegypti mosquitoes, leading to recent urban outbreaks, we fed mosquitoes from Brazil, the Dominican Republic, and the United States artificial blood meals containing 1 of 3 Zika virus strains (Senegal, Cambodia, Mexico) and monitored infection, dissemination, and virus in saliva. Contrary to our hypothesis, Cambodia and Mexica strains were less infectious than the Senegal strain. Only mosquitoes from the Dominican Republic transmitted the Cambodia and Mexica strains. However, blood meals from viremic mice were more infectious than artificial blood meals of comparable doses; the Cambodia strain was not transmitted by mosquitoes from Brazil after artificial blood meals, whereas 61% transmission occurred after a murine blood meal (saliva titers up to 4 log 10 infectious units/collection). Although regional origins of vector populations and virus strain influence transmission efficiency, Ae. aegypti mosquitoes appear to be competent vectors of Zika virus in several regions of the Americas.

    Plasmodium falciparum malaria remains a devastating public health problem. Recent discoveries have shed light on the origin and evolution of Plasmodium parasites and their interactions with their vertebrate and mosquito hosts. P. falciparum malaria originated in Africa from a single horizontal transfer between an infected gorilla and a human, and became global as the result of human migration. Today, P. falciparum malaria is transmitted worldwide by more than 70 different anopheline mosquito species. Recent studies indicate that the mosquito immune system can be a barrier to malaria transmission and that the P. falciparum Pfs47 gene allows the parasite to evade mosquito immune detection. Here, we review the origin and globalization of P. falciparum and integrate this history with analysis of the biology, evolution, and dispersal of the main mosquito vectors. This new perspective broadens our understanding of P. falciparum population structure and the dispersal of important parasite genetic traits.

    1990-07-01

    Container-breeding mosquitoes not only bite people but also transmit many human and animal diseases. The problem with chemical control of these mosquitoes is that the breeding sites are always well dispersed and not easily located, and more manenergy and money are required to treat them individually. Since the adverse effects of pesticides on vector control have been recognized, Toxorhynchites mosquitoes are being reconsidered as a means of reducing the populations of other mosquito species. The bionomic interaction of predator and prey, mass rearing, and some examples of biological control of Toxorhynchites are discussed in this article. Integrated controls combining periodic mass release of gravid Toxorhynchites females and ULV pesticide applications can be used to suppress container-breeding mosquitoes.

    In this paper, we share our findings from a 2-year citizen science program called Mosquito Stoppers. This pest-oriented citizen science project is part of a larger coupled natural-human systems project seeking to understand the fundamental drivers of mosquito population density and spatial variability in potential exposure to mosquito-borne pathogens in a matrix of human construction, urban renewal, and individual behaviors. Focusing on residents in West Baltimore, participants were recruited through neighborhood workshops and festivals. Citizen scientists participated in yard surveys of potential mosquito habitat and in evaluating mosquito nuisance. We found that citizen scientists, with minimal education and training, were able to accurately collect data that reflect trends found in a comparable researcher-generated database.

    Full Text Available Current anticholinesterase pesticides were developed during World War II and are toxic to mammals because they target a catalytic serine residue of acetylcholinesterases (AChEs in insects and in mammals. A sequence analysis of AChEs from 73 species and a three-dimensional model of a malaria-carrying mosquito (Anopheles gambiae AChE (AgAChE reported here show that C286 and R339 of AgAChE are conserved at the opening of the active site of AChEs in 17 invertebrate and four insect species, respectively. Both residues are absent in the active site of AChEs of human, monkey, dog, cat, cattle, rabbit, rat, and mouse. The 17 invertebrates include house mosquito, Japanese encephalitis mosquito, African malaria mosquito, German cockroach, Florida lancelet, rice leaf beetle, African bollworm, beet armyworm, codling moth, diamondback moth, domestic silkworm, honey bee, oat or wheat aphid, the greenbug, melon or cotton aphid, green peach aphid, and English grain aphid. The four insects are house mosquito, Japanese encephalitis mosquito, African malaria mosquito, and German cockroach. The discovery of the two invertebrate-specific residues enables the development of effective and safer pesticides that target the residues present only in mosquito AChEs rather than the ubiquitous serine residue, thus potentially offering an effective control of mosquito-borne malaria. Anti-AgAChE pesticides can be designed to interact with R339 and subsequently covalently bond to C286. Such pesticides would be toxic to mosquitoes but not to mammals.

    A Música Popular Brasileira teve um papel fundamental na disseminação de mensagens contra o sistema político opressor que vigorou no Brasil entre 1964 e 1985. No período do regime militar, qualquer forma de manifestação contra o sistema vigente era considerada subversiva, e seus veiculadores poderiam sofrer sanções como censura, prisão, tortura, deportação, exílio e até a morte. Nesse contexto, muitos artistas foram perseguidos em nome da ordem nacional. Com o cerceamento cada vez mais implac...

    Full Text Available Existem vários tipos de anúncios, alguns de bens, de idéias e, por fim, outros de serviços. Sendo mais específico, propagandas enfatizando serviços pelas empresas são mais raras do que propagandas com foco em bens. O presente artigo testa seis hipóteses em relação à comparação do conteúdo das propagandas de serviços com foco business-to-business e business-to-consumer. Da mesma forma, verifica-se também a existência de diferentes targets na elaboração de seus conteúdos. As sete variáveis avaliadas por meio de análise de conteúdo foram: tipo de anúncio, apelo, manchete, qualidade, preço, segmentação e endereço eletrônico. Os dados foram obtidos de 34 revistas de negócios publicadas no Brasil, totalizando uma amostra de 812 propagandas, das quais 29% foram para serviços business-to-business e 71% com foco business-to-consumer. Os resultados obtidos demonstraram a rejeição de apenas uma das seis hipóteses teoricamente propostas, reforçando a idéia de determinadas características que propagandas business-to-business possuem. Comentários adicionais e contribuições do estudo concluem o artigo.

No entanto, o modo como anunciantes utilizam informações e apelos emocionais em suas mensagens ainda é um assunto pouco estudado. Daí, os objetivos deste artigo foram: a analisar algumas características gerais da propaganda na Internet; b explorar o conteúdo informacional e o apelo emocional da propaganda na Internet. Realizou-se uma pesquisa de caráter exploratório, por meio da análise de conteúdo de uma amostra de 156 anúncios escolhida por conveniência nos sites de maior acesso na Internet brasileira. Os resultados mostraram que a propaganda nos sites analisados é bastante pulverizada quanto às categorias de produto anunciadas, mas que os investimentos estão concentrados em poucas categorias de site. Os tipos de conteúdo informacional mais comumente usados são “disponibilidade” e “componentes ou conteúdo” dos produtos. Também a propaganda utiliza apenas apelos emocionais positivos, o que traz oportunidades para a criação campanhas.

    2017-02-01

    Essential oils from fresh leaves of four aromatic plants viz., Ocimum sanctum, Mentha piperita, Eucalyptus globulus and Plectranthus amboinicus were extracted by hydrodistillation. The test solutions were prepared as 20% essential oil in ethanol and positive control as 20% DEET in ethanol. Essential oil blend was prepared as 5% concentration. Nulliparous, 3-5-day-old female adult Aedes aegypti mosquitoes were used for repellency screening as per ICMR protocol. The study showed that the repellency of 20% essential oil of O. sanctum, M. piperita and P. amboinicus were comparable with that of the standard DEET (20%) as no mosquito landing on the test was observed up to 6 h. The E. globulus oil exhibited mosquito repellency only upto 1½ h. Considerable mosquito landing and feeding was displayed in negative control. In the case of the oil blend, no landing of mosquitoes was seen up to 6 h as that of positive control. The results showed that the essential oil blend from O. sanctum, M. piperita, E. globulus and P. amboinicus could repel Ae. aegypti mosquitoes or prevent from feeding as in the case of DEET even at a lower concentration of 5%. This study demonstrates the potential of essential oils from O. sanctum, M. piperita, E. globulus and P. amboinicus and their blend as mosquito repellents against Ae. aegypti, the vector of dengue, chikungunya and yellow fever.

    The dynamics of a mosquito population depends heavily on climatic variables such as temperature and precipitation. Since climate change models predict that global warming will impact on the frequency and intensity of rainfall, it is important to understand how these variables affect the mosquito populations. We present a model of the dynamics of a Culex quinquefasciatus mosquito population that incorporates the effect of rainfall and use it to study the influence of the number of rainy days and the mean monthly precipitation on the maximum yearly abundance of mosquitoes M max . Additionally, using a fracturing process, we investigate the influence of the variability in daily rainfall on M max . We find that, given a constant value of monthly precipitation, there is an optimum number of rainy days for which M max is a maximum. On the other hand, we show that increasing daily rainfall variability reduces the dependence of M max on the number of rainy days, leading also to a higher abundance of mosquitoes for the case of low mean monthly precipitation. Finally, we explore the effect of the rainfall in the months preceding the wettest season, and we obtain that a regimen with high precipitations throughout the year and a higher variability tends to advance slightly the time at which the peak mosquito abundance occurs, but could significantly change the total mosquito abundance in a year.

    Our research is aimed at developing the technologies necessary to undertake the genetic manipulation of insect vector genomes. In the longer term, we wish to explore the potential that this technology may have for developing novel strategies for the control of vector-borne diseases. The focus of our current research has been to: i) identify and characterise endogenous transposable elements in the genomes of mosquito vectors -research has focussed on identifying both Class I and Class 11 elements and determining their structure and distribution within mosquito genomes; ii) develop and use transfection systems for mosquito cells in culture as a test bed for transformation vectors and promoters - transfection techniques, vector constructs and different promoters driving reporter genes have been utilised to optimise the transformation of both Aedes aegypti and Anopheles gambiae cells in culture; iii) identify putative promoter sequences which are induced in the female mosquito midgut when it takes a blood meal - the Anopheles gambiae trypsin gene locus has been cloned and sequenced and the intergenic regions assessed for their ability to induce reporter gene expression in mosquito gut cells. The progress we have made in each of these areas will be described and discussed in the context of our longer term aim which is to introduce genes coding for antiparasitic agents into mosquito genomes in such a way that they are expressed in the mosquito midgut and disrupt transmission of the malaria parasite.

    In many parts of the United States, mosquitoes were previously nuisance pests. However, they now represent a potential threat in the spread of viral diseases. The Aedes aegypti, Aedes albopictus, and Culex species mosquitoes are endemic to the United States and together may transmit a variety of viral diseases of growing concern, including West Nile virus, chikungunya, dengue fever, and Zika virus. The Centers for Disease Control and Prevention and the Environmental Protection Agency (EPA) recommend N,N-diethyl-meta-toluamide (DEET) as a first-line mosquito repellent, but for patients refusing to use DEET or other conventional repellents, guidance is limited to any EPA-registered product. Therefore, we conducted a systematic review of the literature to identify which EPA-registered personal mosquito repellent provides the best protection from A. aegypti, A. albopictus, and Culex spp. mosquitoes. We abstracted data from 62 published reports of EPA-registered mosquito repellents. The conventional repellent picaridin has the strongest data to support its use as a second-line agent, while IR3535 and oil of lemon eucalyptus are reasonably effective natural products. Citronella, catnip, and 2-undecanone offer limited protection or have limited data. These results can be used by pharmacists and other health care professionals to advise patients on the selection of an EPA-registered mosquito repellent. Regardless of the repellent chosen, it is vital for patients to follow all instructions/precautions in the product labeling to ensure safe and effective use. © 2016 Pharmacotherapy Publications, Inc.

    Full Text Available Abstract Background Problems associated with resistant mosquitoes and the effects on non-target species by chemicals, evoke a reason to find alternative methods to control mosquitoes, like the use of natural predators. In this regard, aquatic coleopterans have been explored less compared to other insect predators. In the present study, an evaluation of the role of the larvae of Acilius sulcatus Linnaeus 1758 (Coleoptera: Dytiscidae as predator of mosquito immatures was made in the laboratory. Its efficacy under field condition was also determined to emphasize its potential as bio-control agent of mosquitoes. Methods In the laboratory, the predation potential of the larvae of A. sulcatus was assessed using the larvae of Culex quinquefasciatus Say 1823 (Diptera: Culicidae as prey at varying predator and prey densities and available space. Under field conditions, the effectiveness of the larvae of A. sulcatus was evaluated through augmentative release in ten cemented tanks hosting immatures of different mosquito species at varying density. The dip density changes in the mosquito immatures were used as indicator for the effectiveness of A. sulcatus larvae. Results A single larva of A. sulcatus consumed on an average 34 IV instar larvae of Cx. quinquefasciatus in a 24 h period. It was observed that feeding rate of A. sulcatus did not differ between the light-on (6 a.m. – 6 p.m., and dark (6 p.m. – 6 a.m. phases, but decreased with the volume of water i.e., space availability.

    Mosquitoes pose a major threat to human health as they spread many deadly diseases like malaria, dengue, chikungunya, filariasis, Japanese encephalitis and Zika. Identification and use of novel molecular tools are essential to combat the spread of vector borne diseases. Genome editing tools have been used for the precise alterations of the gene of interest for producing the desirable trait in mosquitoes. Deletion of functional genes or insertion of toxic genes in vector mosquitoes will produce either knock-out or knock-in mutants that will check the spread of vector-borne diseases. Presently, three types of genome editing tools viz., zinc finger nuclease (ZFN), transcription activator-like effector nucleases (TALEN) and clustered regulatory interspaced short palindromic repeats (CRISPR) and CRISPR associated protein 9 (Cas9) are widely used for the editing of the genomes of diverse organisms. These tools are also applied in vector mosquitoes to control the spread of vector-borne diseases. A few studies have been carried out on genome editing to control the diseases spread by vector mosquitoes and more studies need to be performed with the utilization of more recently invented tools like CRISPR/Cas9 to combat the spread of deadly diseases by vector mosquitoes. The high specificity and flexibility of CRISPR/Cas9 system may offer possibilities for novel genome editing for the control of important diseases spread by vector mosquitoes. In this review, we present the current status of genome editing research on vector mosquitoes and also discuss the future applications of vector mosquito genome editing to control the spread of vectorborne diseases.

    Mosquito breeding sites consist of water pools, which can either be large open areas or highly covered ponds with vegetation, thus with different light exposures combined with the presence in water of xenobiotics including polycyclic aromatic hydrocarbons (PAHs) generated by urban pollution. UV light and PAHs are abiotic factors known to both affect the mosquito insecticide resistance status. Nonetheless, their potential combined effects on the mosquito physiology have never been investigated. The present article aims at describing the effects of UV exposure alongside water contamination with two major PAH pollutants (fluoranthene and benzo[a]pyrene) on a laboratory population of the yellow fever mosquito Aedes aegypti. To evaluate the effects of PAH exposure and low energetic UV (UV-A) irradiation on mosquitoes, different parameters were measured including: (1) The PAH localization and its impact on cell mortality by fluorescent microscopy; (2) The detoxification capacities (cytochrome P450, glutathione-S-transferase, esterase); (3) The responses to oxidative stress (Reactive Oxygen Species-ROS) and (4) The tolerance of mosquito larvae to a bioinsecticide (Bacillus thuringiensis subsp. israelensis-Bti) and to five chemical insecticides (DDT, imidacloprid, permethrin, propoxur and temephos). Contrasting effects regarding mosquito cell mortality, detoxification and oxidative stress were observed as being dependent on the pollutant considered, despite the fact that the two PAHs belong to the same family. Moreover, UV is able to modify pollutant effects on mosquitoes, including tolerance to three insecticides (imidacloprid, propoxur and temephos), cell damage and response to oxidative stress. Taken together, our results suggest that UV and pollution, individually or in combination, are abiotic parameters that can affect the physiology and insecticide tolerance of mosquitoes; but the complexity of their direct effect and of their interaction will require further

    As European colonization spread widely over the African continent the health and physical welfare of the African population gained more and more importance to European colonists who concentrated on capitalizing on African human resources for an improved financial and economic outcome of their colonies. This brought tropical medicine to the top of the European colonial agenda and raised the awareness of the threat of infectious diseases, such as the African Trypanosomiasis or so-called sleeping disease. In 1916 a group of scientists from the pharmaceutical company Bayer AG discovered a substance on the base of dye rather than arsenic. The drug was called Bayer 205 and showed outstanding therapeutic effects. It also reduced adverse reactions in people infected with sleeping disease. As Germany had already lost its colonies, the Bayer company--supported by the German government--negotiated with the English and Belgian governments and was allowed to send an expedition to East Africa. During 1921 and 1923 the new drug was tested in English Rhodesia and Belgian Congo and proved revolutionary, especially in comparison with conventional substances. In due course, the drug Bayer 205 was named Germanin and it was subsequently proposed to use it for political leverage: knowledge and use of the new drug was to be given only in exchange for parts of the former German colonies. However, the reactions of the international media put an end to Germany's neo-colonial-dreams, even before the proposal had reached governmental level. Even so, the incident never disappeared from the mind of those who wished to revive German colonialism. Thus, it is no surprise, that the tale of the discovery and perceived "injustice" of a thwarted scientific success regained an important place in National Socialist propaganda. This article will examine two sources to exemplify the role Germanin attained in National Socialist propaganda: Hellmuth Unger's popular science novel Germanin. Geschichte einer

    To document the diversity and distribution of mosquito species inhabiting the Mexican state of Tamaulipas, collection trips were conducted to all physiographic regions (Grand Northamerican Plains, Coastal Plain of North Gulf, and Sierra Madre Oriental) and subregions across the state. Additionally, we re-examined mosquito specimens in two Mexican entomological collections: the Collection of Insects and Mites of Medical Importance and the Collection of Arthropods of Medical Importance. In total, 3,931 specimens were collected. These represent the two Culicidae subfamilies Anophelinae and Culicinae, 10 tribes, 17 genera, 27 subgenera, 80 named species, and 2 undescribed species. Of these, 3 tribes, 6 genera, 7 subgenera, and 20 species are new records for the mosquito fauna of Tamaulipas. Fourteen species recorded in the historical records were not found in collections made for this study. Taxonomic notes, new distribution limits, and comments about the medical importance of some of the species collected are reported. © The Author 2015.

    The Centers for Disease Control and Prevention (CDC) light traps and Mosquito Magnet X (MMX) traps baited with dry ice, octenol, and a new formulation (granular) of carbon dioxide (CO2) were evaluated against adult mosquitoes in the field. The results showed that the MMX traps (68.6%) baited with dry ice collected more mosquitoes compared to the CDC light traps (32.4%) only. The CDC traps baited with dry ice (64%) collected significantly more mosquitoes than traps baited with CO2 sachets (11%) or octenol (23%). The MMX traps baited with dry ice (85.5%) collected significantly more mosquitoes than traps baited with CO2 sachets (6.5%) or octenol (9%). The CDC traps baited with the formulations of normal and slow release CO2 sachets collected more mosquitoes than the formulation of fast release sachets. The CDC traps baited with fresh sachets and 24-h-exposed sachets collected significantly more mosquitoes than the traps baited with 48-h- and 72-h-exposed sachets.

    A simple microscopic mechanistic model is described of the active amplification within the Johnston's organ of the mosquito species Toxorhynchites brevipalpis. The model is based on the description of the antenna as a forced-damped oscillator coupled to a set of active threads (ensembles of scolopidia) that provide an impulsive force when they twitch. This twitching is in turn controlled by channels that are opened and closed if the antennal oscillation reaches a critical amplitude. The model matches both qualitatively and quantitatively with recent experiments. New results are presented using mathematical homogenization techniques to derive a mesoscopic model as a simple oscillator with nonlinear force and damping characteristics. It is shown how the results from this new model closely resemble those from the microscopic model as the number of threads approach physiologically correct values.

  5. Propaganda, Literature and a Television Mini-Series: Representations of Roger Casement in Germany, 1916-2016

    2018-03-01

    Full Text Available A fairly extensive German-language tradition of depicting Roger Casement exists that has, until now, not been surveyed by cultural historians. Three distinct strands of Casement representation dominate, and often intertwine: 1 Casement as an international humanitarian, 2 Casement as an extreme Irish nationalist, and 3 Casement as a gay martyr. These narratives have been highly dependent on the socio-political context and the needs of the creators. Thus Casement has been depicted as a rabid Irish nationalist within German anti-British propaganda texts during World War One and Two, but also as an international humanitarian who practiced a liberationist nationalism during the years of the democratic Weimar Republic, while the Casement story has in addition been mined to humanise gay men in post-War West Germany.

    Full Text Available For the self-perception of the Kingdom of Italy, founded as late as 1861, the soldiers killed in action during WW I played a particular role. The war memorials built for them along the front between the Stelvio Pass and the Isonzo River, the frontier to the former Austro-Hungarian Empire, are a case in point. After their seizure of power in 1922, the Italian fascists radically converted the memorial culture from the mourning of the dead to their celebration as fascist martyrs. New war memorials were built, now rather driven by the ideas of heroism and sacrifice for the nation – and for future wars. These new war memorials were also erected in regions where no fighting had taken place during WW I, as in South Tyrol, at the Brenner or the Reschen Pass. This was a clear indication of their function as an instrument for political propaganda.

La segunda mitad del siglo XX supondrá finalmente una ruptura con los valores tradicionales confucianos, y la ascensión al poder del Partido Comunista Chino. Sin embargo, en las últimas décadas, el confucianismo ha vuelto a entrar en la escena pública compartiendo, aparentemente, su protagonismo con otros discursos del poder. Todo ello forma parte de un entramado mucho más complejo de la propaganda y, por extensión, la realidad política de la China contemporánea.

    Approximately 8 % of the population, reviewed in the regions subjected to the Chernobyl NPP accident named distrust to official information media as one of the radiophobia causes because of their contradictive, non-expeditions and incomplete nature-such is the conclusion made from the public opinion analysis. Near 90 % of those reviewed, including medical personnel, noted the necessity of more complete medical information. Lectures and discussions by physicians are considered among the primary forms of information on radiation effects and behaviour in emergency situations followed by value of mass media reports. Study of physicians and public opinion in the regions suffered from the accident made it possible to develop a project of radiation-hygienic knowledge propaganda for various population groups. 5 refs.; 5 tabs

  11. State propaganda and mental disorders: the issue of psychiatric casualties among Japanese soldiers during the Asia-Pacific War.

    Science.gov (United States)

    Matsumura, Janice

    2004-01-01

    This article explores the politics of Japanese wartime medical policy, demonstrating how state propaganda about the people and their armed forces influenced authoritative views on health and what might endanger it. By focusing on the obstacles faced by psychiatrists trying to promote more official concern for mental health issues, it challenges the validity of figures indicating a low incidence of psychological trauma among the country's soldiers. Civilian psychiatrists had to contend with the threat of censorship and arrest for even discussing war-induced mental disorders; at the same time, army psychiatrists as military insiders were pressured to convince their patients that their conditions were not serious and did not merit compensation. While discussing the neglected topic of Japanese psychiatric casualties, an attempt is made to provide a comparative approach by referring to the state of military psychiatry in other national settings.

    Full Text Available (Medien-Pädagogik, verstanden als Medienverbund zur programmierten "Unterrichtung" einer breiten Masse wurde bereits vor 1914 erfahren. Zweifelsohne kam es jedoch während dem Ersten Weltkrieg zu einer intensiven Orchestrierung der zur Verfügung stehenden Medien. Die angestrebte Volkserziehung kann dabei als kybernetisches Regelkreismodell betrachtet werden. Als ganz spezielles systemimmanentes Instrument, stellte sich dabei das Kino heraus. Anfangs etwas zögerlich, verstand man es mit Verlauf des Krieges auch in der Donaumonarchie, die Möglichkeiten der bewegten Bilder immer umfassender auszunützen. Das Kino sollte als Regler, dem Publikum Führungsgrößen vor Augen führen und das einzelne Individuum gleichzeitig zu einer Art Selbstregulation auffordern. Vorstellungs- und Wertewelten der Menschen sollten homogenisiert werden und das System in dieser Weise stabilisieren. Offenes Feedback war unerwünscht; Grundstimmungen und Diskurse innerhalb der Bevölkerung blieben jedoch nicht unbemerkt und wurden auf der Leinwand bearbeitet, wobei begründete Befürchtungen, Zweifel und Ängste, zu entkräften versucht wurden. Mit fortschreitender Kriegsdauer taten sich Zensur und Propaganda immer schwerer, ein geschöntes Bild der Situation glaubhaft darzustellen. Schließlich vermochte das Flimmern der Leinwände, die Botschaften des Systems nicht mehr zu vermitteln. Das kybernetische Modell der Volkserziehung über Kamera und Leinwand, welches die Gesellschaft militärisch überprägte, Überlegenheit predigte, Gewalt normalisierte und das kriegsbedingte Sterben humanisierte, musste letztlich scheitern. Der vorliegende Artikel soll einen kurzen Einblick in den Aufbau dieses – letztlich gescheiterten – regulativen Werkes der kinematografischen Propaganda und Zensur in Österreich-Ungarn geben, wobei der Fokus auf der dokumentarischen Berichterstattung vom Krieg liegt, die eine vermeintliche Realität repräsentieren sollte.

    Full Text Available Abstract INTRODUCTION: Cacipacore virus (CPCV, a possible bird-associated flavivirus, has yet to be detected in mosquitoes. Our purpose is examining CPCV in mosquitoes from the Amazon region of Brazil. METHODS: Approximately 3,253 Culicidae (grouped into 264 pools were collected from the Amazon region during 2002-2006 and analyzed using a Flavivirus genus-specific reverse transcription- polymerase chain reaction followed by nested polymerase chain reaction assay and by nucleotide sequencing of amplicons. RESULTS: Nucleotide sequences from five mosquito samples showed high similarity to the those of CPCV originally isolated in the Amazon region. CONCLUSIONS: This is the first report of CPCV-infected mosquitoes which has implications on the arbovirus maintenance in nature and transmission to man.

    Entomological studies conducted during monsoon and post-monsoon season in Manipur State revealed the presence of fifty-five species of mosquitoes under ten genera. Out of the seventeen Anopheles species recorded, Anopheles aconitus, An. dirus and An. nivipes were recorded for the first time from the state. The present study has confirmed the existence of An. dirus, the major malaria vector in the Northeast from a selected area of the state. Among Culicines, four species viz., Aedes nigrostriatus, Malaya genurostris, Aediomyia catasticta and Toxorhynchites splendens which were not reported earlier from this state have been recorded in the present study. With the addition of these seven species of mosquitoes to the earlier record of mosquitoes so far reported from Manipur, the mosquito fauna swells up to one hundred and eleven including the major vectors of malaria of the Northeast and the potential vectors of Japanese encephalitis and dengue virus transmission in India.

    Mosquitoes (Diptera: Culicidae) are vectors of important parasites and pathogens causing death, poverty and social disability worldwide. The overuse of synthetic insecticides to control mosquito vectors lead to resistance, adverse environmental effects and high operational costs. Therefore, the development of eco-friendly control tools is an important public health challenge. In this study, two different essential oils (EO) (geranium, Geranium maculatum, and bergamot, Citrus bergamia) loaded polymeric nanoparticle (PN) were elaborated using polyethylene glycol (PEG) and chitosan (Qx) as the polymeric matrix/coating. In addition, the mosquito larvicidal acute and residual activity of the PN was evaluated on Culex pipiens pipiens. The physicochemical characterization of PN revealed that PEG-PN had sizes nanoparticles containing essential oil are a promising source of eco-friendly mosquito larvicidal products.

Esta situação relança, com grande acuidade, o problema do recrutamento, da participação e do seguimento de voluntários sadios e doentes nestes experimentos. O presente artigo objetiva, assim, descrever as representações elaboradas pelos indivíduos que recusaram engajar-se em testagens terapêuticos contra o HIV. A análise dessas representações nos ajudará a compreender os significados que acionados na recusa em engajar-se em práticas médico-científicas que contam com a utilização do corpo, bem como na ocasião de expressão da solidariedade em relação as pessoas infectadas pela Aids. Este trabalho centra-se sobre voluntários potenciais para as testagens, explorando as dificuldades que lhes são tradicionalmente atribuídas no que se refere à compreensão das mensagens a eles destinadas. Nossa hipótese é de que o desconhecimento observado entre os “não-voluntários” através de suas representações das substâncias vacinais, reflete sua posição subjetiva em relação ao que eles mesmos qualificaram de “mundo da Aids” e em relação à medicina e à ciência.

    Posteriormente comenta qué es lo que se ha hecho con toda la profundidad que se merece pero con simpleza de palabras y en términos sencillos, cómo se desarrolló la Vacuna Sintética contra la malaria: ¿Por qué malaria?, porque esta es una enfermedad de gran trascendencia; aclara que él no le teme ni le molesta el cuestionamiento científico sobre el desarrollo de esta investigación, por el contrario lo acepta y lo goza porque es el ejercicio intelectual; lo que sí le molesta es el morbo alrededor de ello, por esto pidió al doctor Muñoz que al final se adelante un debate al respecto.

    Dice a continuación que las vacunas tradicionales son biológicas como todo el mundo lo sabe, es el microorganismo causal mismo que se muta ose mata, pero que descomponiendo la estructura química de sus moléculas, con el concepto de la síntesis química se podrían rehacer químicamente y ser utilizadas como vacuna.

    Decidieron entonces atacar el problema de la vacuna a través de esta metodología creando la vacuna contra la malaria de la cual se conoce su estructura química, y aclara que las vacunas químicas tienen otra ventaja, que son puras, con menos reacciones adversas que las tradicionales.

    We report that two laboratory colonies of Culex quinquefasciatus and Culex pipiens mosquitoes were experimentally unable to transmit ZIKV either up to 21 days post an infectious blood meal or up to 14 days post intrathoracic inoculation. Infectious viral particles were detected in bodies, heads or saliva by a plaque forming unit assay on Vero cells. We therefore consider it unlikely that Culex mosquitoes are involved in the rapid spread of ZIKV. This article is copyright of The Authors, 2016.

  16. The impact of metagenomic interplay on the mosquito redox homeostasis.

    Science.gov (United States)

    Champion, Cody J; Xu, Jiannong

    2017-04-01

    Mosquitoes are exposed to oxidative challenges throughout their life cycle. The primary challenge comes from a blood meal. The blood digestion turns the midgut into an oxidative environment, which imposes pressure not only on mosquito fecundity and other physiological traits but also on the microbiota in the midgut. During evolution, mosquitoes have developed numerous oxidative defense mechanisms to maintain redox homeostasis in the midgut. In addition to antioxidants, SOD, catalase, and glutathione system, sufficient supply of the reducing agent, NADPH, is vital for a successful defense against oxidative stress. Increasing evidence indicates that in response to oxidative stress, cells reconfigure metabolic pathways to increase the generation of NADPH through NADP-reducing networks including the pentose phosphate pathway and others. The microbial homeostasis is critical for the functional contributions to various host phenotypes. The symbiotic microbiota is regulated largely by the Duox-ROS pathway in Drosophila. In mosquitoes, Duox-ROS pathway, heme-mediated signaling, antimicrobial peptide production and C-type lectins work in concert to maintain the dynamic microbial community in the midgut. Microbial mechanisms against oxidative stress in this context are not well understood. Emerging evidence that microbial metabolites trigger host oxidative response warrants further study on the metagenomic interplay in an oxidative environment like mosquito gut ecosystem. Besides the classical Drosophila model, hematophagous insects like mosquitoes provide an alternative model system to study redox homeostasis in a symbiotic metagenomic context.

    To determine if the unique host assemblages in zoos influence blood-feeding by mosquitoes (Diptera: Culicidae), a sampling programme was conducted in Greenville and Riverbanks Zoos, South Carolina, U.S.A., from April 2009 to October 2010. A total of 4355 female mosquitoes of 14 species were collected, of which 106 individuals of nine species were blood-fed. The most common taxa were Aedes albopictus (Skuse), Aedes triseriatus (Say), Anopheles punctipennis (Say), Culex erraticus (Dyar & Knab), Culex pipiens complex (L.) and Culex restuans (Theobald). Molecular analyses (cytochrome b) of bloodmeals revealed that mosquitoes fed on captive animals, humans and wildlife, and took mixed bloodmeals. Host species included one amphibian, 16 birds, 10 mammals (including humans) and two reptiles. Minimum dispersal distances after feeding on captive hosts ranged from 15.5 m to 327.0 m. Mosquito-host associations generally conformed to previous accounts, indicating that mosquito behaviour inside zoos reflects that outside zoos. However, novel variation in host use, including new, exotic host records, warrants further investigation. Zoos, thus, can be used as experiment environments in which to study mosquito behaviour, and the findings extrapolated to non-zoo areas, while providing medical and veterinary benefits to zoo animals, employees and patrons. © 2012 The Authors.

    Field studies indicate adult mosquitoes (Culicidae) host low diversity communities of bacteria that vary greatly among individuals and species. In contrast, it remains unclear how adult mosquitoes acquire their microbiome, what influences community structure, and whether the microbiome is important for survival. Here we used pyrosequencing of 16S rRNA to characterize the bacterial communities of three mosquito species reared under identical conditions. Two of these species, Aedes aegypti and Anopheles gambiae, are anautogenous and must blood feed to produce eggs, while one, Georgecraigius atropalpus, is autogenous and produces eggs without blood feeding. Each mosquito species contained a low diversity community comprised primarily of aerobic bacteria acquired primarily from the aquatic habitat in which larvae developed. Our results suggested the communities in Ae. aegypti and An. gambiae larvae share more similarities with one another than with Ge. atropalpus. Studies with Ae. aegypti also strongly suggested that adults transstadially acquired several members of the larval bacterial community, but only four genera of bacteria present in blood fed females were detected on eggs. Functional assays showed that axenic larvae of each species failed to develop beyond the first instar. Experiments with Ae. aegypti indicated several members of the microbial community and Escherichia coli successfully colonized axenic larvae and rescued development. Overall, our results provide new insights about the acquisition and structure of bacterial communities in mosquitoes. They also indicate three mosquito species spanning the breadth of the Culicidae depend on their gut microbiome for development. PMID:24766707

    Full Text Available The Malpighian tubules and hindgut are the renal excretory tissues of mosquitoes; they are essential to maintaining hemolymph water and solute homeostasis. Moreover, they make important contributions to detoxifying metabolic wastes and xenobiotics in the hemolymph. We have focused on elucidating the molecular mechanisms of Malpighian tubule function in adult female mosquitoes and developing chemical tools as prototypes for next-generation mosquitocides that would act via a novel mechanism of action (i.e., renal failure. To date, we have targeted inward rectifier potassium (Kir channels expressed in the Malpighian tubules of the yellow fever mosquito Aedes aegypti and malaria mosquito Anopheles gambiae. Inhibition of these channels with small molecules inhibits transepithelial K+ and fluid secretion in Malpighian tubules, leading to a disruption of hemolymph K+ and fluid homeostasis in adult female mosquitoes. In addition, we have used next-generation sequencing to characterize the transcriptome of Malpighian tubules in the Asian tiger mosquito Aedes albopictus, before and after blood meals, to reveal new molecular targets for potentially disrupting Malpighian tubule function. Within 24 h after a blood meal, the Malpighian tubules enhance the mRNA expression of genes encoding mechanisms involved with the detoxification of metabolic wastes produced during blood digestion (e.g., heme, NH3, reactive oxygen species. The development of chemical tools targeting these molecular mechanisms in Malpighian tubules may offer a promising avenue for the development of mosquitocides that are highly-selective against hematophagous females, which are the only life stage that transmits pathogens.

    Newly established ponds, which are highly dynamic systems with changing levels of biological interactions among species, are common larval mosquito habitats. We investigated the impact of crustacean abundance and taxa diversity on mosquito oviposition and larval development. The effects of the biological larvicide Bacillus thuringiensis israelensis (Bti) on mosquito larvae were monitored according to fluctuations in crustacean communities. Populations of the mosquito Culex pipiens colonized artificial ponds that contained crustacean communities at different time points of colonization by crustaceans: 1) 'no colonization' (no crustaceans), 2) 'simultaneous colonization' by crustaceans and mosquitoes, and 3) 'head-start colonization' by crustaceans (preceding colonization by mosquitoes). All types of ponds were treated with three concentrations of Bti (10, 100, or 1,000 µg/liter). Colonization of all ponds by Cx. pipiens (in terms of oviposition, larval abundance, and larval development) decreased significantly with increasing diversity of crustacean taxa. The total abundance of crustaceans had a minor effect on colonization by Cx. pipiens. The presence of crustaceans increased the sensitivity of Cx. pipiens larvae to Bti treatment by a factor of 10 and delayed the time of recolonization. This effect of Bti was relevant in the short term. In the long term, the presence of Cx. pipiens was determined by crustacean biodiversity. © 2013 The Society for Vector Ecology.

  2. Non-genetic determinants of mosquito competence for malaria parasites.

    Thierry Lefèvre

    Full Text Available Understanding how mosquito vectors and malaria parasites interact is of fundamental interest, and it also offers novel perspectives for disease control. Both the genetic and environmental contexts are known to affect the ability of mosquitoes to support malaria development and transmission, i.e., vector competence. Although the role of environment has long been recognized, much work has focused on host and parasite genetic effects. However, the last few years have seen a surge of studies revealing a great diversity of ways in which non-genetic factors can interfere with mosquito-Plasmodium interactions. Here, we review the current evidence for such environmentally mediated effects, including ambient temperature, mosquito diet, microbial gut flora, and infection history, and we identify additional factors previously overlooked in mosquito-Plasmodium interactions. We also discuss epidemiological implications, and the evolutionary consequences for vector immunity and parasite transmission strategies. Finally, we propose directions for further research and argue that an improved knowledge of non-genetic influences on mosquito-Plasmodium interactions could aid in implementing conventional malaria control measures and contribute to the design of novel strategies.

    The global health crisis posed by vector-borne diseases is so great in scope that it is clearly insurmountable without the active help of tens-or hundreds- of thousands of individuals, working to identify and eradicate risk in communities around the world. Mobile devices equipped with data collection capabilities and visualization opportunities are lowering the barrier for participation in data collection efforts. The GLOBE Observer Mosquito Habitat Mapper (MHM) provides citizen scientists with an easy to use mobile platform to identify and locate mosquito breeding sites in their community. The app also supports the identification of vector taxa in the larvae development phase via a built-in key, which provides important information for scientists and public health officials tracking the rate of range expansion of invasive vector species and associated health threats. GO Mosquito is actively working with other citizen scientist programs across the world to ensure interoperability of data through standardization of metadata fields specific to vector monitoring, and through the development of APIs that allow for data exchange and shared data display through a UN-sponsored proof of concept project, Global Mosquito Alert. Avenues of application for mosquito vector data-both directly, by public health entities, and by modelers who employ remotely sensed environmental data to project mosquito population dynamics and epidemic disease will be featured.

  5. Composition of human skin microbiota affects attractiveness to malaria mosquitoes.

    Directory of Open Access Journals (Sweden)

    Niels O Verhulst

    Full Text Available The African malaria mosquito Anopheles gambiae sensu stricto continues to play an important role in malaria transmission, which is aggravated by its high degree of anthropophily, making it among the foremost vectors of this disease. In the current study we set out to unravel the strong association between this mosquito species and human beings, as it is determined by odorant cues derived from the human skin. Microbial communities on the skin play key roles in the production of human body odour. We demonstrate that the composition of the skin microbiota affects the degree of attractiveness of human beings to this mosquito species. Bacterial plate counts and 16S rRNA sequencing revealed that individuals that are highly attractive to An. gambiae s.s. have a significantly higher abundance, but lower diversity of bacteria on their skin than individuals that are poorly attractive. Bacterial genera that are correlated with the relative degree of attractiveness to mosquitoes were identified. The discovery of the connection between skin microbial populations and attractiveness to mosquitoes may lead to the development of new mosquito attractants and personalized methods for protection against vectors of malaria and other infectious diseases.

    The control of mosquito populations with insecticide treated bed nets and indoor residual sprays remains the cornerstone of malaria reduction and elimination programs. In light of widespread insecticide resistance in mosquitoes, however, alternative strategies for reducing transmission by the mosquito vector are urgently needed, including the identification of safe compounds that affect vectorial capacity via mechanisms that differ from fast-acting insecticides. Here, we show that compounds targeting steroid hormone signaling disrupt multiple biological processes that are key to the ability of mosquitoes to transmit malaria. When an agonist of the steroid hormone 20-hydroxyecdysone (20E) is applied to Anopheles gambiae females, which are the dominant malaria mosquito vector in Sub Saharan Africa, it substantially shortens lifespan, prevents insemination and egg production, and significantly blocks Plasmodium falciparum development, three components that are crucial to malaria transmission. Modeling the impact of these effects on Anopheles population dynamics and Plasmodium transmission predicts that disrupting steroid hormone signaling using 20E agonists would affect malaria transmission to a similar extent as insecticides. Manipulating 20E pathways therefore provides a powerful new approach to tackle malaria transmission by the mosquito vector, particularly in areas affected by the spread of insecticide resistance.

    Observation on predation activities of guppies (Poecilia reticulata) on the larvae of three species of mosquito, namely Aedes albopictus, Aedes aegypti, and Culex quinquefasciatus was carried out under laboratory conditions. Male and female guppies were used as predators for predation experiments on the 4th instars of mosquito larvae. The daily feeding rates comparing male and female guppies on mosquito larvae were different; the female guppies consumed more mosquito larvae than male guppies did. The daily feeding rates of female guppies were 121.3 for Ae. aegypti, 105.6 for Ae. albopictus, and 72.3 for Cx. quinquefasciatus. The daily feeding rates of male guppies were 98.6 for Ae. aegypti, 73.6 for Ae. albopictus, and 47.6 for Cx. quinquefasciatus. In terms of prey preference, there was greater preference towards mosquito larvae of Ae. aegypti, followed by Ae. albopictus, and the least preferred was Cx. quinquefasciatus. Male and female guppies consumed more mosquito larvae during lights on (day time) compared with lights off (night time). The water volume, prey species, number of fish predators available, prey densities, and prey's sex also influenced the predation activities.

    Background Malaria is an important cause of illness and death in people living in many parts of the world, especially sub-Saharan Africa. Long-lasting insecticide treated bed nets (LLINs) and indoor residual spraying (IRS) reduce malaria transmission by targeting the adult mosquito vector and are key components of malaria control programmes. However, mosquito numbers may also be reduced by larval source management (LSM), which targets mosquito larvae as they mature in aquatic habitats. This is conducted by permanently or temporarily reducing the availability of larval habitats (habitat modification and habitat manipulation), or by adding substances to standing water that either kill or inhibit the development of larvae (larviciding). Objectives To evaluate the effectiveness of mosquito LSM for preventing malaria. Search methods We searched the Cochrane Infectious Diseases Group Specialized Register; Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; EMBASE; CABS Abstracts; and LILACS up to 24 October 2012. We handsearched the Tropical Diseases Bulletin from 1900 to 2010, the archives of the World Health Organization (up to 11 February 2011), and the literature database of the Armed Forces Pest Management Board (up to 2 March 2011). We also contacted colleagues in the field for relevant articles. Selection criteria We included cluster randomized controlled trials (cluster-RCTs), controlled before-and-after trials with at least one year of baseline data, and randomized cross-over trials that compared LSM with no LSM for malaria control. We excluded trials that evaluated biological control of anopheline mosquitoes with larvivorous fish. Data collection and analysis At least two authors assessed each trial for eligibility. We extracted data and at least two authors independently determined the risk of bias in the included studies. We resolved all disagreements through discussion with a third author. We analyzed the data using Review Manager 5 software

    Full Text Available In the context of Second World War and its impact in North Africa, propaganda destined for Arab populations takes multiform aspects: radio, newspapers, leaflets, etc.. The propaganda conducted by Great Britain through the BBC, making use of the Arabic language, began in 1939. Programmes from Radio London were in fact an answer to German radio propaganda which had great success in North Africa. During the brief war operations in Morocco, Algeria and Tunisia, from 8 November 1942 to 13 May 1943, this propaganda tried to show and to improve the image of different combatants and to convince Arabs of the justice of their cause. A weekly newspaper published by Great Britain, “Akhbar al Ousbou” (or Weekly Information, was exclusively reserved for the governmental authorities. During the North Africa campaign (Torch, the Royal Air Force dropped leaflets in Arabic, trying to explain their war aims and to secure the support of the population. This article examines the developing of British Arabic propaganda and seeks to measure its degree of success or failure in the face of other subversive propaganda particularly from Germany and Italy and especially its impacts on the North African populations from 1939 till May 1943.

A pesar del impacto positivo sobre la pandemia que se ha conseguido gracias a los avances en la terapia antirretroviral (TARV, el HIV/sida sigue constituyendo un grave problema para la salud pública, especialmente en los países en desarrollo, donde es difícil el acceso al tratamiento. En el mundo, 33 millones de personas viven con el virus del sida, mientras que en la Argentina se calcula que habría unos 120 000 infectados. Uno de los desafíos para lograr una vacuna contra el HIV es la variabilidad viral. El grupo M, responsable de la pandemia, se encuentra dividido en 10 subtipos y varios sub-subtipos, además de las 48 formas recombinantes circulantes y más de cien formas recombinantes únicas. La epidemia de HIV en nuestro país es tan compleja como en el resto del mundo, con la co-circulación principalmente de virus pertenecientes al subtipo B y recombinantes BF (CRF12_BF y derivadas. A pesar de la cantidad de trabajos dedicados a la caracterización de la respuesta inmune y al desarrollo de vacunas, no queda claro cuál es el impacto de la variabilidad en la elección del antígeno. Trabajos realizados en nuestro laboratorio demuestran el papel que juega la inmunidad celular con respecto a las variantes recombinantes BF, tanto en humanos como en modelos animales.

    Mosquito surveillance in Europe is essential for early detection of invasive species with public health importance and prevention and control of emerging pathogens. In Portugal, a vector surveillance national program-REVIVE (REde de VIgilância de VEctores)-has been operating since 2008 under the custody of Portuguese Ministry of Health. The REVIVE is responsible for the nationwide surveillance of hematophagous arthropods. Surveillance for West Nile virus (WNV) and other flaviviruses in adult mosquitoes is continuously performed. Adult mosquitoes-collected mainly with Centre for Disease Control light traps baited with CO2-and larvae were systematically collected from a wide range of habitats in 20 subregions (NUTS III). Around 500,000 mosquitoes were trapped in more than 3,000 trap nights and 3,500 positive larvae surveys, in which 24 species were recorded. The viral activity detected in mosquito populations in these years has been limited to insect specific flaviviruses (ISFs) non-pathogenic to humans. Rather than emergency response, REVIVE allows timely detection of changes in abundance and species diversity providing valuable knowledge to health authorities, which may take control measures of vector populations reducing its impact on public health. This work aims to present the REVIVE operation and to expose data regarding mosquito species composition and detected ISFs.

    The native microflora associated with mosquitoes have important roles in mosquito development and vector competence. Sequencing of bacterial V3 region from 16S rRNA genes across the developmental stages of Culex mosquitoes (early and late larval instars, pupae and adults) was used to test the hypothesis that bacteria found in the larval stage of Culex are transstadially transmitted to the adult stage, and to compare the microbiomes of field-collected versus laboratory-reared mosquitoes. Beta diversity analysis revealed that bacterial community structure differed among three life stages (larvae, pupae and adults) of Culex tarsalis. Although only ~2% of the total number of bacterial OTUs were found in all stages, sequences from these OTUs accounted for nearly 82% of the total bacterial sequences recovered from all stages. Thorsellia (Gammaproteobacteria) was the most abundant bacterial taxon found across all developmental stages of field-collected Culex mosquitoes, but was rare in mosquitoes from laboratory-reared colonies. The proportion of Thorsellia sequences in the microbiomes of mosquito life stages varied ontogenetically with the greatest proportions recovered from the pupae of C. tarsalis and the lowest from newly emerged adults. The microbiome of field-collected late instar larvae was not influenced significantly by differences in the microbiota of the habitat due to habitat age or biopesticide treatments. The microbiome diversity was the greatest in the early instar larvae and the lowest in laboratory-reared mosquitoes. Bacterial communities in early instar C. tarsalis larvae were significantly more diverse when compared to late instar larvae, pupae and newly emerged adults. Some of the bacterial OTUs found in the early instar larvae were also found across developmental stages. Thorsellia dominated the bacterial communities in field-collected immature stages but occurred at much lower relative abundance in adults. Differences in microbiota observed in larval

    Most alphaviruses are arthropod-borne and utilize mosquitoes as vectors for transmission to susceptible vertebrate hosts. This ability to infect both mosquitoes and vertebrates is essential for maintenance of most alphaviruses in nature. A recently characterized alphavirus, Eilat virus (EILV), isolated from a pool of Anopheles coustani s.I. is unable to replicate in vertebrate cell lines. The EILV host range restriction occurs at both attachment/entry as well as genomic RNA replication levels. Here we investigated the mosquito vector range of EILV in species encompassing three genera that are responsible for maintenance of other alphaviruses in nature. Susceptibility studies were performed in four mosquito species: Aedes albopictus, A. aegypti, Anopheles gambiae, and Culex quinquefasciatus via intrathoracic and oral routes utilizing EILV and EILV expressing red fluorescent protein (-eRFP) clones. EILV-eRFP was injected at 10(7) PFU/mL to visualize replication in various mosquito organs at 7 days post-infection. Mosquitoes were also injected with EILV at 10(4)-10(1) PFU/mosquito and virus replication was measured via plaque assays at day 7 post-infection. Lastly, mosquitoes were provided bloodmeals containing EILV-eRFP at doses of 10(9), 10(7), 10(5) PFU/mL, and infection and dissemination rates were determined at 14 days post-infection. All four species were susceptible via the intrathoracic route; however, replication was 10-100 fold less than typical for most alphaviruses, and infection was limited to midgut-associated muscle tissue and salivary glands. A. albopictus was refractory to oral infection, while A. gambiae and C. quinquefasciatus were susceptible only at 10(9) PFU/mL dose. In contrast, A. aegypti was susceptible at both 10(9) and 10(7) PFU/mL doses, with body infection rates of 78% and 63%, and dissemination rates of 26% and 8%, respectively. The exclusion of vertebrates in its maintenance cycle may have facilitated the adaptation of EILV to a single

    Full Text Available The main aim of this work is to identify, analyse and propose to modern readers and scholars, in an imagological perspective, how war propaganda, through trench papers, was able to create a group identity and a war mentality during the Great War. In particular, this article concentrates on the vis-à-vis between Italy and Austria examining both an italian and an austrian trench paper (“La Tradotta” and the “Tiroler Soldaten-Zeitung”. Through the comparison between some of the most interesting pieces of the two, the author tried to make the reader understand how war propaganda worked with language and how important it was in the creation of consent. It emerges a skilful use of persuasion strategies which can be also seen in a more current perspective and can be useful for the study of modern mass media and their capacity to drive people’s way of thinking and behaviour.
