Democratização na radiodifusão: da utopia à esperança com o compromisso público do PT
Authors: Caldas Graça
Published: November 2018

Da anacrônica Legislação do Código Brasileiro de Telecomunicações de 1962, ao sistema atual de outorgas de canais de rádio e televisão, poucas mudanças ocorreram para viabilizar a democratização da comunicação. As expectativas da sociedade civil mobilizada nos anos 80, sob a liderança do Fórum Nacional pela Democratização da Comunicação, foram várias vezes frustradas, apesar de avanços localizados como a criação do Conselho de Comunicação Social (1991) e a Lei da Cabodifusão (1998). Das habituais práticas clientelistas de distribuição de emissoras de rádio e televisão, que atinge seu ápice no governo Sarney (1985-1989), a supostos critérios objetivos e técnicos do governo FHC (1989-2003), a moeda de troca permanece na esfera política e econômica, em detrimento dos interesses sociais. A utopia de democratização pela instância regulatória não se cumpre e dá lugar á mobilização de novos atores sociais, que reivindicam qualidade na programação na televisão e pressionam o Estado para a estruturação de um sistema público de comunicação. O atual governo de Luiz Inácio Lula da Silva sinaliza para a perspectiva de ruptura com o modelo vigente, de caráter eminentemente privado, ao retomar a discussão sobre a Lei Eletrônica de Comunicação de Massa. Resta saber se o agora presidente Luiz Inácio Lula da Silva cumprirá o compromisso da campanha presidencial de 1994, de reestruturar e democratizar o sistema de radiodifusão no pais para garantir a pluralidade das

JN e a estrela errante da produção local. O papel do telejornalismo na construção das redes de televisão
Authors: Silveira Ada Cristina Machado da , Seibt Micheli
Published: November 2018

O papel do telejornalismo na construção das redes de televisão requer estudar fenômenos sobro os quais temos pouca informação sistematizada. Este artigo trata da reconstituição dos acontecimentos em torno à iniciativa de inserir diariamente um bloco local dentro da edição do Jornal Nacional emitido pela Rede Globo em cadeia nacional já nos seus primeiros meses de existência (1969). Apontamos o caso de uma emissora que inaugurou a articulação da programação de uma cabeça-de-rede com a programação regional e local. A partir dele é possível ter uma perspectiva de análise privilegiada e também avaliar perdas e ganhos na trajetória de uma emissora comunitária, a TV imembui, de Santa Maria-RS. A análise da concessão do canal televisivo a um grupo local do interior brasileiro 35 anos depois de sua inauguração permite considerar várias ordens de fatores mutuamente imbricados: um certo atrofiamento da produção de conteúdos locais, a persistência do telejornalismo nesta tarefa e a estruturação do sistema de redes televisivas no Brasil.

El territorio como espacio de confluencias. Luchas por el hábitat urbano durante la recuperación democrática en la ciudad de Córdoba (1982-1987)
Authors: Medina Leticia
Published: November 2018

Sobre la base del análisis de archivos documentales, fuentes estatales y periodísticas y entrevistas orales, se propone una lectura histórica sobre la movilización en defensa del hábitat urbano en Córdoba durante la última recuperación democrática, atendiendo a las interacciones entre diversos actores, la articulación de demandas, los recursos movilizados, los repertorios puestos en juego y los significados otorgados por los actores –así como las justificaciones que tomaron estado público– respecto de sus propias iniciativas y de las características del contexto.Se sostiene que el hábitat configuró un campo de experiencias en el que se combinaron y coexistieron acciones disruptivas, iniciativas normalizadoras, propuestas partidarias y formas de participación desde abajo en los espacios institucionales, impulsando y ampliando los procesos de democratización en curso. La experiencia de lucha por el hábitat ofrece asimismo sugerentes pistas para avanzar en reflexiones en torno a la tensión entre lo social y lo político en la acción colectiva.

War as nothing but a duel: war as an institution and the construction of the Western military profession
Authors: Käihkö Ilmari
Published: November 2018

Like all repetitive human interaction, even war has been institutionalized and fought according to conventions and norms. Historically, this institutionalization is apparent from the way war has been compared to the duel, first in the 14th century and most famously by Carl von Clausewitz 5 centuries later. This article continues this train of thought and argues that the observed limits of Western “professional orthodoxy” and “strategic vocabulary” can be traced to how war has been institutionalized by the military profession. This offers an alternative explanation to the prevailing views of why the West has struggled in contemporary wars: it is the fundamental mismatch between these professional norms in the West and those held by their opponents that forms the biggest asymmetry in contemporary war. As this asymmetry is unlikely to disappear, these professional norms need to be reconsidered: just like the aristocracy with the duel by the late 19th century, the Western military profession appears stuck in an institution that is increasingly becoming obsolete. Without such reconsideration, the attainment of decision – the central strategic objective in war – and hence victory in future wars will remain uncertain.
Wall-Sided Glaciers
Authors: Lewandowski Wojciech , Zgorzelski Marek
Published: November 2018

In the literature devoted to geomorphology and glaciology not much has been written about wall-sided glaciers, thanks to which high mountains have their specific landscape character. It is also difficult to find in the literature of the subject a classification of the wallsided glacier forms which would take into account the richness and variety of this phenomenon. After many years of experience in almost all highest mountains of Asia, South America and Europe, the authors decided to fill this gap and therefore to provoke a discussion among the geomorphologists.

The Effect of Changes in Administrative Division on the Economic Position of the Largest Cities in Poland
Authors: Wilk Waldemar
Published: November 2018

Among the functions fulfilled by cities in relation to their hinterland, an important function is that of public administration. Changes in administrative division, instituted in Poland in 1999, have either weakened or strengthened the economical role of many cities.

A city’s position within the hierarchy of the centers of public administration within a country has, in Poland’s case, a significant effect upon the geographical movements of companies. An attempt was made to preliminarily gauge the effect of administrative changes upon the location of corporate offices. Changes in the distribution of companies providing the selected types of services in the 100 largest Polish cities were taken into account. The relationship between the change in the number of companies in each city and the potential social and economic role of the city in the general sense was examined.
Nature and Tourism on Tropical and Subtropical Islands
Authors: Jędrusik Maciej
Published: November 2018

Tropical and subtropical islands have become an important tourist destination. The islands are concentrated in eight areas of the world. Evaluating the natural tourist potential of these areas, it seems that the most attractive are the islands of Mid and West Indian Ocean and the Polynesia. Yet, these locations are less popular then the theoretically less naturally attractive Caribbean, Mediterranean and East Atlantic islands.

This leads to the conclusion that nature is not the most important decisive factor in choosing tourist destinations, and “tourist paradises” are formed on islands regardless of their natural attributes. Tourists are mainly attracted by the “myth” of a tropical island, and the most important criterion is the distance from home and travel time.

This paper presents the scope of geographical research conducted at Arctowski Station during the 30th Polish Antarctic Expedition. The research included meteorological, climatological, geomorphological and glaciological issues. During the expedition, research was conducted on sandur sediments on the outwash plain of Sphinx Glacier, the size of the aeolian transport, intensity of periglacial phenomena, and the way in which environmental conditions are recorded on quartz grains collected on the Admiralty Bay beaches. Detailed measurements of the basic meteorological components were made, geomorphological maps of the outwash plains of Sphinx, Baranowski, and Windy Glaciers were also completed.
Cyclic Changes of Climate in Europe During the Last Millenium According to Dendrological Data
Authors: Boryczka Jerzy , Stopa-Boryczka Maria , Bijak Szymon
Published: November 2018

The paper discusses periodic climate changes in Europe determined on the basis of dendrochronological data dating back one thousand years. In tree-ring width sequences of trees growing in Poland there are approximately 8-, 11-, 100- and 180- year periods. The tree-ring widths of oaks growing in Poland for the last centuries are characterised, without any significant amplitude, by 8- and 11-year periods (Tab. 1). In turn, chronologies of pine, spruce, larch, oak and fir growing in Europe are characterised by 100- and 180-year periods (Tab. 2). Cycles of dendrochronological variables approximate cycles of air temperature and North Atlantic Oscillation NAO as well as those of solar activity. The forecast of annual growth (ring width) for 2001-2100 was calculated by interference of the tree-ring width cycles determined by the sinusoidal regression method. Because of much longer empirical sequences of specific periods, the credibility of forecasts for tree-ring widths is greater than that for air temperature.
Tourism in Rural Areas of Castilla-La Mancha
Authors: Zwierzchowska Joanna
Published: November 2018

The rural areas of Castilla-La Mancha have managed to preserve a unique natural and cultural character. A great diversity of touristic qualities makes the region especially attractive for development of rural tourism.

For many years, the autonomous community of Castilla-La Mancha had to cope with numerous socio-economic difficulties. Development of the tourist industry resulted in diversification of income sources and higher level of employment. Another positive effect of the process was activation of female members of the community. The principle aim of this article is to underline the complementary role of tourism in rural areas in relation to agriculture and urban tourism.
Stages of Development of Cartography as a Science
Authors: Ostrowski Wiesław
Published: November 2018

Three essential periods may be singled out in the development of cartography as a science:

1. From the beginning of the last century to the mid-sixties is the period of development of cartography as a distinct science.

2. The period dating from the mid-sixties till the eighties is the golden age of development of theoretical cartography with special amplification of discussions on the subject of the theoretical fundamentals of cartography. At the end of the former period and at the beginning of the latter, cartography finally distinguished itself as an independent science. In 1959, the International Cartographic Association was founded. In 1961, the International Yearbook of Cartography was published for the first time and beginning in 1969, Polski Przegląd Kartograficzny (the Polish Cartographic Review). A year earlier, Komisja Kartograficzna Polskiego Towarzystwa Geograficznego (the Cartographic Commission of the Polish Geographical Society) was established.

3. Since the mid-eighties, and even somewhat earlier, use of new IT technologies, especially interest in the map as an element of geographic information systems, has become the dominating trend in cartography.
Bioclimatic Conditions of Paris, Rome and Budapest on the Basis of the Universal Thermal Climate Index
Authors: Idzikowska Danuta
Published: November 2018

The aim of this study was to examine the main features of the bioclimatic conditions of three European cities using a new Universal Thermal Climate Index. Daily values of meteorological variables for 12 UTC for the cities for 1990-2001 were used in the study. Using the frequency of UTCI and one-way Anova, the results showed that in all the three cities “no thermal stress” dominated throughout the year. “Extreme” values of heat as well as “cold stress” were observed but in none of the cities “extreme cold stress” occurred. The values of UTCI differed for all the three cities in each studied year. The cities differed from each other in each month during the whole year with the exception of spring - March and April.
Regional Conditions for Maximum Probable Discharge in Poland’s Rivers
Authors: Gutry-Korycka Małgorzata , Woronko Dariusz , Suchożebrski Jarosław
Published: November 2018

The purpose of this study was to obtain and verify the methods of catchment regionalization for annual maximum discharge. An identification of Polish rivers was performed based on regional frequency analyses including recognition of regions homogeneous with respect to their physical properties and river flow parameters. The results suggest a division into two regional groups: mountain and lowland catchments. Statistical tests verify the regionalization obtained and allow to calculate regional probability curves for these two catchment groups. The results obtained may be helpful in the analysis of floods in ungauged catchments and in those where hydrological observations were performed during a short period, especially when the dependence of the maximum probable flows on their physico-geographical features in catchments under analysis has been proved.

THE STUDY OF THE ANTECEDENTS OF RETAIL SHOPPERS’ REPATRONAGE INTENTIONS: AN EMPIRICAL STUDY
Authors: Budi Hartono Kusuma Andreas Widjaja,
Published: November 2018

One of important factors that determine the success of retail stores is how to make customers go to shop there, in which they have to shop there continuously. So, retailers should   have to satisfy customers in order to keep customers. In this research, the researcher would like to test and describe customer satisfaction and repatronage  intentions, through eight  variables in Carrefour and Hypermart, and developed into seven hypotheses. This research uses 160 samples to ask their perceptions about Carrefour and Hypermart. Then, from that research, there are two hypotheses that are  rejected and five hypotheses  that  are  accepted.  Perceived product  quality  and perceived price are considered as insignificant antecedents of customer satisfaction. However, perceived service quality, store assortment, trust and commitment are considered as significant antecedents   of   customers’ satisfaction, and customer satisfaction is significant antecedent of repatronage intentions.
Investigation of LEPS potential energy surface for the interaction of a Pt(111) surface with a hydrogen atom
Authors: VURDU Can Doğan
Published: November 2018

In this work, the identification of a potential energy surface between H atom and Pt(111) surface has been studied through the use of London-Eyring-Polanyi-Sato potential energy function (PEF).  The energy values for the H–Pt(111) interaction calculated using density functional theory were used to determine the parameters of this PEF by using a nonlinear least-squares method.  For this study, four symmetric sites on the surface were considered as a top site, bridge site, fcc-hollow site and hcp hollow site.  It can be determined which sites on the Pt surface are penetration region, adsorption site or scattering site by defining the potential energy surface.  It is found that both of the hollow sites of the surface are regions where H atom can penetrate directly to subsurface and it can be held easily on the surface.

Published: November 2018

l objetivo de este trabajo fue establecer posibles relaciones entre características de lluvias y características físicas y químicas de sedimentos en una cuenca experimental ubicada en la ciudad de Bogotá (región tropical altoandina). Los sedimentos se recolectaron en periodos quincenales durante cinco meses, en los dos desarenadores del humedal construido de la Pontifica Universidad Javeriana, Bogotá. La recolección de sedimentos se realizó con trampas especialmente diseñadas para el sitio de estudio. Los resultados muestran un diámetro medio (D50) de 128 µm, concentraciones medias de Cr = 36 mg/kg, Cu = 115 mg/kg, Pb = 273 mg/kg y Zn = 1173 mg/kg. Se encontró una relación entre la precipitación y las características de los sedimentos, lo cual puede guiar eventuales prácticas de utilización de sedimentos: (i) un menor número de días de tiempo seco se relaciona con mayores tamaños de partículas y menores concentraciones de metales; (ii) mayores magnitudes de intensidad y de altura total de lluvia se relacionan con una menor cantidad de partículas de grano grueso que llegan a los desarenadores

It was concluded that productivity stood out among the other elements confirming its importance in determining firm competitiveness. Limitations of this study consists on the theoretical nature, there is the need for an empirical study to verify the practical effect of productivity on competitiveness at the firm level.Key-words: competitiveness, productivity, firm, company, system thinking.
Omisión del proclítico de tiempo, aspecto, modo y persona en mazahua
Authors: Mora Bustos Armando
Published: November 2018

En mazahua, lengua Otomangue, el proclítico que codifica tiempo, aspecto, modo (TAM) y persona se realiza como morfema cero. Este morfema cero se indexa en la palabra verbal de diferentes oraciones gramaticales. Los contextos gramaticales en donde el proclítico TAM y de persona se realiza como morfema cero son: básicamente en tercera persona, tiempo-aspecto perfecto; este sentido tempo-aspectual está enfatizado por clíticos de aspecto puntual. Igualmente, el morfema cero coaparece con verbos en los que se prenasaliza o se palataliza el primer segmento del radical verbal. Desde una perspectiva pragmática, la referencia del sujeto gramatical y de los rasgos TAM se recupera en el contexto discursivo; la relación gramatical sujeto está expresada en diferentes recursos lingüísticos, esto es, frases nominales y clíticos (pronominales, demostrativos y plurales). La realización del proclítico TAM y de persona como morfema cero está relacionada con la estructura de la información. La referencia corresponde al estatus informativo tópico.
Teacher’s Situated Knowledge Through Metaphor Construction and Its Story- Licensing
Authors: Serna Dimas Héctor Manuel
Published: November 2018

This theoretical article argues for metaphor construction and development to explain how teachers situate their knowledge and make sense of their teaching lives and practices. However, the process of metaphor construction must go beyond the scope of cognitive theories, and their systematization of concepts in metaphors. Metaphors, as conscious attempts to situate teachers’ knowledge, must be considered as a text whose constituting elements are the teachers’ values, belief systems, ideologies, professional knowledge, and culture intertwined in their minds. The concept of story licensing plays a key role in validating the definition and development of metaphors to explain teachers’ situated knowledge construction.

Authors: Giraldo Giraldo Camilo , Ríos Londoño Dora Miryam , Cardona Cifuentes Fabio Andrés
Published: November 2018

La escritura y la gramática se transforman y adaptan según el desarrollo tecnológico y cultural. El objetivo de este estudio empírico es caracterizar la escritura del WhatsApp para demostrar que en él se despliega una gramática al margen de la normativa institucional de la Real Academia Española. Se aplicó encuesta y entrevista a 208 estudiantes de ambos géneros entre los 17 y 25 años, adscritos a cuatro universidades de Manizales (2 públicas y 2 privadas) y se recopilaron, para el análisis, capturas de pantalla con diálogos en WhatsApp. Se encontró que el 57 % de los participantes expresó que acatan las normas y un 76 % afirma que en WhatsApp también se debe respetar la gramática establecida. Sin embargo, en aparente contradicción, un 75,5 % expresó que es innecesario acatar normativas, un 43 % no las cumplen y el 46 % manifestó que no es fácil hacerlo en el WhatsApp. Se concluye que la escritura –y, por ende, la gramática– en el WhatsApp es una actividad cotidiana que orienta su curso al margen de las formalidades gramaticales de la RAE.

Published: November 2018

The conifer sawfly, Neodiprion huizeensis (Hymenoptera: Diprionidae), is an injurious leaf feeder of Pinus spp. (Pinaceae) in China. Its parasitoid complex of overwintering cocoons was investigated in Weining, Guizhou during 2012. The average parasitism rate of overwintering cocoons of N. huizeensis by the parasitoid complex was 34.6%. The parasitoid complex included Drino auricapita (Diptera: Tachinidae), ichneumonids, and Trichomalus sp. (Hymenoptera: Pteromalidae). The average parasitism rate of N. huizeensis by D. auricapita was 13.1%. The puparial period of D. auricapita averaged 16.4 ± 0.1 d. The female to male ratio was 1.1: 1. The ichneumonid complex included Aptesis grandis, A. melana, A. nigricoxa, Delomerista indica, Lamachus rufiabdominalis, L. nigrus, Bathythrix sp., Caenocryptus sp., Exyston spp., Gelis sp., Goryphus sp., and Olesicampe sp. The parasitism rate of N. huizeensis by ichneumonids was 17.1%. The parasitism rate of N. huizeensis by Trichomalus sp. was 4.5%, and the female to male ratio was 3.7: 1. The dominant species of parasitoids was D. auricapita followed by A. melana. The emergence of overwintered adults of N. huizeensis had two peaks: the first from the 17th to the 23rd of February, 2012; the second from February 29th to March 15th, 2012. The emergence of the parasitoid complexes coincided with each other and occurred from February 23rd to March 6th, 2012.

Published: November 2018

La gravedad de los daños ocasionados en aguacate por la mosca blanca (Paraleyrodes sp. pos. bondari) y la dificultad para controlarla, han obligado a los investigadores y agricultores a buscar alternativas para su manejo. Se investigó el ciclo biológico de esta mosca blanca y la relación que tienen los factores ambientales con la población de este insecto; además, se hizo un reconocimiento de sus principales enemigos naturales en el cultivo de aguacate. Para ello se realizaron monitoreos bisemanales a 10 árboles de tres cultivares de aguacate: Hass, Lorena y Choquette, en dos fincas productoras de Fresno (Tolima) durante nueve meses, en los cuales se evaluó el porcentaje (%) de área foliar ocupada por la mosca blanca. Se midieron diariamente las variables climáticas: precipitación, humedad relativa y temperatura. La cuantificación e identificación de fauna asociada al cultivo se llevó a cabo durante siete meses. Paraleyrodes sp. pos. bondari tuvo un ciclo de vida promedio de 27,7 ± 0,19 días. El cultivar Lorena tuvo la mayor presencia de Paraleyrodes; en la finca La Chiripa la humedad relativa mostró un coeficiente de correlación inverso con respecto al porcentaje de área foliar ocupada por la mosca en todos los cultivares. Se identificaron los géneros Encarsia sp., Eretmocerus sp. y Amitus sp. como los principales enemigos naturales potenciales de Paraleyrodes sp. pos. bondari.
Development and reproductive performance of Chrysoperla externa (Neuroptera: Chrysopidae) using preys from wheat crop
Authors: Pitwak Juliana , Menezes Jr. Ayres Oliveira , Ventura Maurício Ursi
Published: November 2018

Biological parameters of Chrysoperla externa were assessed in laboratory. The effect of the preys on biological parameters and reproductive performance were assessed when the following food treatments were provided: Sitobion avenae in all larval instars; Rhopasosiphum padi in all larval instars; Anagasta kuehniella eggs in the first and second instars and Dichelops melacanthus eggs in the third; R. padi in the first and second instars and D. melacanthus in the third instar. All foods provided satisfactory development and reproductive performance. Changing larvae food from A. kuehniella to D. melacanthus did not affect its survival. However, changing larvae food from R. padi to D. melacanthus reduced survival. When larvae were fed with R. padi (1st and 2nd instars) and D. melacanthus (3rd instar), C. externa laid more eggs than when larvae were fed only with aphids. Other parameters either were not affected, or were little affected by the diet change. Results showed that aphis are important food sources for C. externa, and this predator may also predate and develop on D. melacanthus eggs.

El anillador de la guayaba es un lepidóptero recientemente identificado como Carmenta theobromae que ha causado pérdidas significativas en cultivos de guayaba de la Provincia de Vélez, Santander. El objetivo de esta investigación consistió en estudiar los estados de huevo y larva del anillador en campo y laboratorio durante el primer semestre de 2014. En campo, los sitios de oviposición se describieron en árboles barrenados y, en laboratorio, se examinaron las posturas en cortezas del tallo de guayaba. Se evaluó la supervivencia y duración del estado larval de inmaduros recolectados en campo en cuatro dietas semi-artificiales: aserrín de guayabo, dos dietas formuladas para Spodoptera frugiperda y otra para Synanthedon pictipes. Se describieron las características morfométricas del huevo y la larva con especímenes recolectados en cultivos de guayaba. Los sitios de oviposición se encontraron en la corteza principalmente del tallo donde las posturas fueron simples, espaciadas y de forma oblonga o elipsoidal. No se encontraron diferencias estadísticas en los tratamientos supervivencia y duración del estado larval. La duración promedio de la fase larval fue de 13,92 ± 1,36 días para individuos con longitud mayor a 10,63 ± 0,31 mm. El huevo midió 0,22 ± 0,012 mm de ancho y 0,37 ± 0,011 mm de longitud. Se identificaron cuatro estadios larvales a través del coeficiente de Dyar y distribución de frecuencias de medidas del ancho cefálico. La larva madura tiene ganchos (“crochets”) distribuidos uniordinalmente y un par de bandas en el pronoto como C. theobromae, barrenador de cacao en Venezuela.

Se presenta la primera lista de especies de Saturniidae, Sphingidae y Geometridae (Lepidoptera) de la Reserva de la Biósfera Yabotí y sus alrededores en Misiones, Argentina. Esta Reserva es una de las áreas protegidas más extensas de la “Selva Paranaense”, la ecorregión más biodiversa de Argentina y altamente vulnerable por el extremo grado de fragmentación y degradación a la que está sometida. El trabajo de campo se realizó en ocho localidades durante la primavera y verano de 2012. Se utilizó trampa de luz para la atracción de los ejemplares y captura individual. La completitud de los muestreos se evaluó mediante curvas de acumulación de especies y estimadores no paramétricos de riqueza. Se identificaron 22 especies de Saturniidae, con cuatro nuevos registros para la fauna de Argentina: Paradaemonia meridionalis (Arsenurinae) y Catacantha ferruginea, Hidripa paranensis y Travassosula subfumata (Hemileucinae). Además, se determinaron 21 especies de Sphingidae y 40 de Geometridae, con seis registros nuevos de esta última familia para Argentina: Opisthoxia corinnaria, O. aurelia, Polla carnipennis y P. ochreicosta (Ennominae), Eois isographata (Larentiinae) y el primer registro de Racasta (Oenochrominae). El número de especies colectadas en cada familia representa alrededor del 60 % del total esperado en el área de estudio, por lo que se sugiere aumentar el esfuerzo de muestreo. Además, la carencia de información sobre la biología y ecología de la mayoría de las especies encontradas sustenta la necesidad de realizar más investigación sobre estos aspectos.

El psílido de la papa Bactericera cockerelli afecta a las solanáceas en México, por el daño directo que causa, además, de que es transmisor de patógenos procariotes como Candidatus Liberibacter solanacerum (psyllaurous). Este insecto es combatido principalmente con productos químicos. Sin embargo, en la actualidad, se buscan nuevas estrategias para su manejo como el uso de hongos entomopatógenos. El objetivo de este trabajo fue evaluar la susceptibilidad del psílido de la papa a dos cepas comerciales y dos nativas de Metarizhium anisopliae y Beauveria bassiana, así como confirmar la identificación de las mismas mediante técnicas moleculares. Los bioensayos se realizaron con la cepa nativa MA25 de M. anisopliae y las comerciales Metabich® (MA28) y Bassianil® (BB09) y la nativa BB42 de Be. bassiana. Se probaron cinco concentraciones sobre ninfas del tercer estadio de B. cockerelli y se obtuvieron sus CL50 y CL95. Todas las cepas resultaron patógenas para el psílido de la papa, las más tóxicas fueron BB09, BB42 y MA28. La mortalidad fluctuó entre 90 a 100% con las concentraciones más altas de cada cepa: la más virulenta fue BB09, con una CL50 de 2,99 x 104 conidias mL-1 y MA25 la menos virulenta tuvo una CL50 de 6,34 x 105 conidias ml-1. Mediante la clonación y la secuenciación de la región ITS de los rADN 18S, se corroboró que las cepas nativas identificadas por morfología microscópica y claves taxonómicas corresponden a Be. bassiana y M. anisopliae.

This study quantified the concentration of heavy metals (copper, zinc, cadmium, lead and nickel) in the biomass of two ant species, Camponotus atriceps and Dorymyrmex brunneus, which are dominant in forests and crop areas, respectively, in Sinop, Mato Grosso, Brazil. Ant sampling pitfall traps were used in both land use types, and metal concentrations in the biomass were obtained by means of atomic absorption spectrometry. The two species were selected because they were the most abundant in each land use type, considering the volume of biomass necessary for the chemical analysis. The results showed that with the exception of copper, heavy metals revealed higher concentrations in D. brunneus from crop areas than in C. atriceps from native forests. Such results are associated with the fact that the crop areas received high inputs of agrochemicals through the management of corn and soybean crops. Thus, ants are good indicators of contamination and environmental pollution in tropical regions, as the highest concentration of heavy metals was expected in the crop areas in relation to the adjacent forest area.

Los cultivos de café de sombra generan ambientes similares a los ecosistemas de montaña en comparación con los monocultivos de café expuestos al sol. Aunque las mariposas se consideran bioindicadoras del estado de salud del ecosistema se desconoce su diversidad en sistemas cafeteros de Santander, donde el café se siembra exclusivamente bajo sombra. Se describe la estructura y composición del ensamblaje de mariposas (Papilionoidea) en un cafetal con sombrío (hacienda La Capellanía, Curití, Santander) a 1.756 m (agosto-septiembre, 2014). En tres transectos paralelos de 50 m dentro del cultivo se ubicaron nueve trampas Van Someren-Rydon cebadas con fruta descompuesta, y especímenes adicionales fueron capturados con red entomológica. La representatividad del muestreo (Ecuación de Clench) fue 81,67 %. Se capturaron 341 individuos de 49 especies de las familias Nymphalidae (S = 39), Pieridae (S = 7), Papilionidae (S = 2) y Lycaenidae (S = 1). Las especies más abundantes fueron Cissia pompilia, Graphita griphe y Hermeuptychia harmonia. Se describió la riqueza (α =16), dominancia (D = 0,07), equidad (J´= 0,81) y los números efectivos de especies (°D = 58,8, 1D= 23,73 y 2D = 14,2 6). Se relacionó la estructura vegetal con la composición de mariposas (análisis de correspondencia canónica). El porcentaje de cobertura arbórea, la altura, el DAP y la cantidad de los árboles explicaron significativamente la abundancia de mariposas. Este estudio es de los pioneros en describir la diversidad de mariposas en cafetales con sombrío del departamento del Santander. Los agroecosistemas cafeterosde sombra tradicional pueden beneficiar la diversidad de mariposas, debido a que la heterogeneidad de su estructura vegetal ofrece mayor disponibilidad de recursos y refugio.

Considering the important roles of pollinators in ecosystem services, their identification and studies of their behavior would be extremely important to efforts directed towards their preservation and management. With the aim of examining the diversity and behavior of the floral visitors to Campomanesia adamantium (Cambessédes) O. Berg
(“guavira”) and how they act in the pollination process, a total of 31 species belonging to the orders Hymenoptera (79.30 %), Coleoptera (11.34 %), Diptera (9.1 %), and Hemiptera (0.24 %) were identified. Among the Hymenoptera, africanized Apis mellifera, Brachygastra lecheguana, and Trachymyrmex sp. were considered dominant. Foraging was
most intense between 07:00 and 10:00 h, with decreased activity after 13:00 h. The insects visited the plants in search of pollen and nectar, with pollen being the principal resource offered. Among the pollinators, africanized Apis mellifera stood out due to their behavior, frequency of visitation, abundance (being responsible for 53.24 % of all floral visits),
and their constant presence on C. adamantium flowers during the entire observation period. Other insects (wasps, ants, and coleopterans) were associated with floral tissue predation.

Maize is attacked by various pest species, including the key-pest of stored maize, Sitophilus zeamais (Coleoptera: Curculionidae). This study determined the LC50 and LD50 of neem-based insecticides (AzaMax® and Natuneem®) in comparison to a synthetic pyrethroid insecticide (Decis® 25 CE) to S. zeamais. The bioassays consisted of insects’ exposure alone (topical application with microsyringe) and exposure of both insects and seeds treated simultaneously. The final bioassays used four to six concentrations of each formulation per bioassay, diluted in distilled water. The bioassays were run with the use of 10 non-sexed adults of S. zeamais per replication and mortality was assessed after 48 h of exposure. The data regarding concentration and dose-mortality were analyzed by probit analysis. Both LC50 and LD50 were used to calculate LCR and LDR’s and their respective confidence interval (CI). After using topical application, the bioassays yielded LD50-values of 51.32, 76.76 and 42.75 μL of AzaMax, Natuneem and Decis/g of insects, respectively. The bioassays with simultaneous exposure of both insects and seeds yielded LC50-values of 4.01, 4.46 and 0.41 μL of AzaMax, Natuneem and Decis/g of seeds, respectively. Regarding the fact that there were no significant differences between the LC50-values of the botanical insecticides, both of them can be used to manage S. zeamais infesting stored corn. The cost to treat maize and to obtain effective control of S. zeamais is cheapest for Decis<Natuneem<Azamax. The LC50-values found in our study would be equivalent to use 8.02, 8.92 and 0.82 L of AzaMax, Natuneem and Decis/ton of seeds.
