Sírfidos afidófagos en huertas agroecológicas y convencionales del cinturón verde de Córdoba

El conocimiento de los enemigos naturales de insectos fitófagos que se alimentan de cultivos hortícolas es fundamental para implementar estrategias adecuadas de manejo y reducir las pérdidas que éstos ocasionan. Los sistemas agrícolas simplificados (ej. baja diversidad vegetal) y basados en la utilización de insumos sintéticos (ej. pesticidas, herbicidas) limitan la ocurrencia de especies, particularmente de los agentes de mortalidad de los insectos fitófagos, con la consecuente disminución en el control de sus poblaciones y el aumento de especies plaga. Factores ecológicos tales como características de las borduras, superficie cultivada, composición de la comunidad vegetal presente, etc., contribuyen a modificar la riqueza de especies y la estructura de las comunidades de insectos asociados a un cultivo. El manejo de estos factores puede incrementar la diversidad de recursos florales necesarios en la dieta de los enemigos naturales, la disponibilidad de refugio para sobrepasar condiciones adversas, favorecer las interacciones planta-fitófago que sean inocuas para los cultivos y que alberguen agentes de mortalidad de las especies plagas, etc; lo cual contribuye a la supervivencia y aumento de las poblaciones de los controladores biológicos. Dentro de la familia Syrphidae (Diptera) existen especies cuyas larvas son importantes depredadoras de áfidos, plagas muy recurrentes en cultivos hortícolas, y de otros insectos de cuerpo blando; mientras que sus adultos visitan flores y pueden comportarse como polinizadores. El objetivo del trabajo fue determinar la riqueza y abundancia de géneros y especies de sírfidos afidófagos en 12 huertas con diferentes tipos de manejo (6 agroecológicas y 6 convencionales) en el cinturón verde de la ciudad de Córdoba, durante las campañas 2018-19 y 2019-20. Para la recolección de los insectos, en cada campo se realizó un recorrido en forma de ?Z? y sobre él se trazaron al azar tres transectas de 5 x 1 m cada una en cada especie cultivada, a fin de colectar los insectos. También se implementaron cinco transectas de 5 x 1 m (c/u) en cada uno de los bordes que rodean los cultivos. Los sírfidos adultos fueron capturados de forma manual con frascos plásticos que luego fueron llevados al laboratorio para su identificación. Los estados inmaduros (larvas y pupas) recolectados en los campos, fueron criados en laboratorio dentro de envases plásticos que se revisaron cada tres días para verificar la emergencia de las moscas adultas o de sus parasitoides. Los insectos se identificaron a nivel de género y especie utilizando claves dicotómicas específicas de la familia y se evaluó la abundancia total en relación al tipo de manejo empleado en las huertas. Los géneros predominantes fueron Allograpta y Toxomerus. Con menor frecuencia se encontraron representantes del género Dioprosopa (ex Pseudodoros). Allograpta exotica fue la especie más abundante, seguida por Toxomerus politus. En menor medida se encontró A. obliqua, Dioprosopa clavata y cuatro morfoespecies del género Toxomerus con unos pocos individuos. En total se recolectaron 395 insectos, siendo los campos convencionales los que presentaron mayor abundancia total con un 55% de los ejemplares, mientras que los agroecológicos el 45% restante. A fin de promover un incremento en la riqueza y abundancia de estos enemigos naturales, consideramos importante continuar investigando aspectos de la estructura del paisaje y del tipo de manejo en las huertas.Fil: Grosso, Gerardo Mario.

XIPE: the X-ray Imaging Polarimetry Explorer

X-ray polarimetry, sometimes alone, and sometimes coupled to spectral and temporal variability measurements and to imaging, allows a wealth of physical phenomena in astrophysics to be studied. X-ray polarimetry investigates the acceleration process, for example, including those typical of magnetic reconnection in solar flares, but also emission in the strong magnetic fields of neutron stars and white dwarfs. It detects scattering in asymmetric structures such as accretion disks and columns, and in the so-called molecular torus and ionization cones. In addition, it allows fundamental physics in regimes of gravity and of magnetic field intensity not accessible to experiments on the Earth to be probed. Finally, models that describe fundamental interactions (e.g. quantum gravity and the extension of the Standard Model) can be tested. We describe in this paper the X-ray Imaging Polarimetry Explorer (XIPE), proposed in June 2012 to the first ESA call for a small mission with a launch in 2017 but not selected. XIPE is composed of two out of the three existing JET-X telescopes with two Gas Pixel Detectors (GPD) filled with a He-DME mixture at their focus and two additional GPDs filled with pressurized Ar-DME facing the sun. The Minimum Detectable Polarization is 14 % at 1 mCrab in 10E5 s (2-10 keV) and 0.6 % for an X10 class flare. The Half Energy Width, measured at PANTER X-ray test facility (MPE, Germany) with JET-X optics is 24 arcsec. XIPE takes advantage of a low-earth equatorial orbit with Malindi as down-link station and of a Mission Operation Center (MOC) at INPE (Brazil).Comment: 49 pages, 14 figures, 6 tables.

XIPE: the X-ray imaging polarimetry explorer

Abstract X-ray polarimetry, sometimes alone, and sometimes coupled to spectral and temporal variability measurements and to imaging, allows a wealth of physical phenomena in astrophysics to be studied. X-ray polarimetry investigates the acceleration process, for example, including those typical of magnetic reconnection in solar flares, but also emission in the strong magnetic fields of neutron stars and white dwarfs. It detects scattering in asymmetric structures such as accretion disks and columns, and in the so-called molecular torus and ionization cones. In addition, it allows fundamental physics in regimes of gravity and of magnetic field intensity not accessible to experiments on the Earth to be probed. Finally, models that describe fundamental interactions (e.g. quantum gravity and the extension of the Standard Model) can be tested. We describe in this paper the X-ray Imaging Polarimetry Explorer (XIPE), proposed in June 2012 to the first ESA call for a small mission with a launch in 2017. The proposal was, unfortunately, not selected. To be compliant with this schedule, we designed the payload mostly with existing items. The XIPE proposal takes advantage of the completed phase A of POLARIX for an ASI small mission program that was cancelled, but is different in many aspects: the detectors, the presence of a solar flare polarimeter and photometer and the use of a light platform derived by a mass production for a cluster of satellites. XIPE is composed of two out of the three existing JET-X telescopes with two Gas Pixel Detectors (GPD) filled with a He-DME mixture at their focus. Two additional GPDs filled with a 3-bar Ar-DME mixture always face the Sun to detect polarization from solar flares. The Minimum Detectable Polarization of a 1 mCrab source reaches 14 % in the 2-10 keV band in 105 s for pointed observations, and 0.6 % for an X10 class solar flare in the 15-35 keV energy band. The imaging capability is 24 arcsec Half Energy Width (HEW) in a Field of View of 14.7 arcmin × 14.7 arcmin. The spectral resolution is 20 % at 6 keV and the time resolution is 8 mus. The imaging capabilities of the JET-X optics and of the GPD have been demonstrated by a recent calibration campaign at PANTER X-ray test facility of the Max-Planck-Institut für extraterrestrische Physik (MPE, Germany). XIPE takes advantage of a low-earth equatorial orbit with Malindi as down-link station and of a Mission Operation Center (MOC) at INPE (Brazil). The data policy is organized with a Core Program that comprises three months of Science Verification Phase and 25 % of net observing time in the following 2 years. A competitive Guest Observer program covers the remaining 75 % of the net observing time

XIPE: the x-ray imaging polarimetry explorer

XIPE, the X-ray Imaging Polarimetry Explorer, is a mission dedicated to X-ray Astronomy. At the time of writing XIPE is in a competitive phase A as fourth medium size mission of ESA (M4). It promises to reopen the polarimetry window in high energy Astrophysics after more than 4 decades thanks to a detector that efficiently exploits the photoelectric effect and to X-ray optics with large effective area. XIPE uniqueness is time-spectrally-spatially- resolved X-ray polarimetry as a breakthrough in high energy astrophysics and fundamental physics. Indeed the payload consists of three Gas Pixel Detectors at the focus of three X-ray optics with a total effective area larger than one XMM mirror but with a low weight. The payload is compatible with the fairing of the Vega launcher. XIPE is designed as an observatory for X-ray astronomers with 75 % of the time dedicated to a Guest Observer competitive program and it is organized as a consortium across Europe with main contributions from Italy, Germany, Spain, United Kingdom, Poland, Sweden

Heme Oxygenase-1 Signaling and Redox Homeostasis in Physiopathological Conditions

Heme-oxygenase is the enzyme responsible for degradation of endogenous iron protoporphyirin heme; it catalyzes the reaction’s rate-limiting step, resulting in the release of carbon monoxide (CO), ferrous ions, and biliverdin (BV), which is successively reduced in bilirubin (BR) by biliverdin reductase. Several studies have drawn attention to the controversial role of HO-1, the enzyme inducible isoform, pointing out its implications in cancer and other diseases development, but also underlining the importance of its antioxidant activity. The contribution of HO-1 in redox homeostasis leads to a relevant decrease in cells oxidative damage, which can be reconducted to its cytoprotective effects explicated alongside other endogenous mechanisms involving genes like TIGAR (TP53-induced glycolysis and apoptosis regulator), but also to the therapeutic functions of heme main transformation products, especially carbon monoxide (CO), which has been shown to be effective on GSH levels implementation sustaining body’s antioxidant response to oxidative stress. The aim of this review was to collect most of the knowledge on HO-1 from literature, analyzing different perspectives to try and put forward a hypothesis on revealing yet unknown HO-1-involved pathways that could be useful to promote development of new therapeutical strategies, and lay the foundation for further investigation to fully understand this important antioxidant system

STRAY19: assessment of the benefits of a stray light baffle on the Science Objectives of SWG3.2

In February 2016, the Athena Working Groups and Topical Panels assessed the impact of X-ray stray light on the Athena science. Since then, the baseline configuration of the Athena mirrors has changed. The cost-constrained reduction of the number of mirror rows from 20 to 15 (current baseline) notably led to an increase of the stray-to-image effective area ratio. The impact of stray light could be reduced via the implementation of a dedicated baffle. ASST thus asked the Working Groups and Topical Panels to assess the scientific benefits of a stray light baffle in the framework of the so-called STRAY19 exercise. The present document provides a preliminary assessment of the quantitative benefits of a stray light baffle on the level-1 science objectives of SWG 3.2 Star formation and Evolution. This document therefore supersedes the previous TN from SWG 3.2 on this subject. Hereafter, we compare a 100% efficient baffle (resulting in no stray light contamination) with the currently estimated level of stray light corresponding to the 15 row mirror as requested by ASST

Insectos benéficos en la vegetación espontánea de huertas agroecológicas: Un análisis a escala local

Evaluamos la abundancia de enemigos naturales (Hymenoptera y Diptera) en función de variables de la vegetación de bordes en huertas agroecológicas de Córdoba. Los insectos se capturaron utilizando trampas de agua amarillas colocadas en bordes de 9 huertas, durante 48hs, en dos oportunidades. Se realizaron 5 transectas (6x1m) y 5 cuadratas (1x1m) en cada borde para cuantificar las variables de vegetación. Los resultados de los modelos lineales generalizados mixtos indican que mientras que la abundancia de himenópteros y parasitoides aumentó con la abundancia de flores, la abundancia de estos grupos y la de dípteros, disminuyó con el aumento en la diversidad de flores. La cobertura del dosel se relacionó negativamente con la abundancia de Diptera y la cobertura vegetal del suelo se relacionó positivamente con la abundancia de predadores. Las características de la vegetación afectan diferencialmente a los enemigos naturales dependiendo de su identidad taxonómica y funcional.We evaluated the abundance of natural enemies (Hymenoptera and Diptera) in relation to variables of the vegetation in margins of agroecological gardens of Córdoba. The insects were captured using yellow water traps placed on edges of 9 orchards, during 48 hours, on two occasions. Five transects (6x1m) and 5 quadrats (1x1m) were made on each edge to quantify the vegetation variables. The results of the mixed generalized linear models indicate that while the abundance of hymenoptera and parasitoids increased with the abundance of flowers, the abundance of these groups and that of Diptera decreased with the increase in flower diversity. The canopy cover was negatively related to the abundance of Diptera and the soil vegetation cover was positively related to the abundance of predators. The characteristics of the vegetation differentially affect natural enemies depending on their taxonomic and functional identity.Fil: Bordunale, Agostina.
