This is a great opportunity to bring together producers, agronomist and researchers in the area of forage seed production from all over the world to share knowledge and experiences and to talk about common areas of interest. Herbage Seed production in Argentina has increased in the last years. Our exports have been going up while the imports have descended. At the same time, the demand for good quality forages has increased since cattle raising activities have been improving. This imposes and opportunity and a challenge for seed producers to improve their production systems and to us, researchers, to find new ways to help and contribute to this goal. We sincerely hope this conference will open the door to ideas and new areas of research and will give us, researchers and producers from South America, new insights to pursue further objectives to augment yield and quality of our seed production systems. I am very grateful to the local organizing committee for the hard work, responsibility and commitment in getting things ready for the conference. I am indebted to our sponsors for their support and contribution and to the organizing institutions for the possibility of putting together this conference. We deeply hope this conference will come up to your expectations and that you all have a productive conference and an enjoyable stay at our wonderful country. Yours sincerely, Maria Andrea Tomás President Local Organizing Committee of the 9th IHSG Conference 6 IHSG 2017 – Pergamino, Argentina Dear colleagues, We welcome delegates to the 9th IHSG Conference at Pergamino. This is the first time the Conference has been held in South America and is the culmination of four year’s work by Andrea Tomas and the local organizing committee. Our last conference was in 2015 at Lanzhou, China and these conferences were the first time that the IHSG had moved outside of Europe, North America and Australia/New Zealand. I have attended 7 of the previous 8 IHSG Conferences and a number of Workshops and I look forward to our time together in Pergamino. The value of Conferences is not only in the ideas presented in formal presentations both conference oral and posters, but in the informal sharing of ideas with other researchers, extension workers and seed growers. I encourage all delegates to make contact with two or more other international delegates that are working in areas that interest you. I have seed industry friends in Argentina that I first met at the 1st IHSG Conference in Denmark in 1987 and have kept in contact over the following year. I have been a regular visitor to Argentina and Uruguay over the past four years and have had the opportunity to visit many seed production farms/estancio’s. The post conference tour will give you a taste of seed and crop production in Argentina. Seed production in Argentina is both well established and with considerable scale. Higher spring/summer temperatures and shorter daylengths than the traditional herbage seed production areas of Oregon, Denmark and New Zealand that presents management challenges for seed growers. I know you will enjoy both the culture of South America and your interaction with seed researchers, seed company agronomists and extension advisors and seed growers who you will meet and interact with this week. Many thanks-muchas gracias to the Local Organizing Committee and sponsors who are helping to support the conference. Enjoy your week.

  • The Larva of Mecistogaster Amalia (Odonata: Pseudostigmatidae)
    Received 04 June 2009; revised and accepted 09 September 2009 The larva of Mecistogaster amalia (Odonata: Pseudostigmatidae) Javier Muz6n, Soledad Weigel Munoz & Raul Ernesto Campos lnstituto de Limnologfa "Dr. R.A. Ringuelet'; (CONICET- CCT La Plata), C.C. 712, 1900, La Plata, Argentina. <[email protected]> Key words: Odonata, dragonfly, Mecistogaster amalia, Pseudostigmatidae, larva, phytotelmata. ABSTRACT The final larval stadium of Mecistogaster amalia is described and illustrated for the first time based on one female collected in a tree hole in Misiones province, Argen­ tina, and compared with all known larvae of related genera. Larval morphology of Pseudostigmatidae is briefly discussed. INTRODUCTION Pseudostigmatidae include 17 species in five neotropical genera, i.e. Anomisma McLachlan, 1877, Mecistogaster Rambur, 1842, Megaloprepus Rambur, 1842, Microstigma Rambur, 1842, and Pseudostigma Selys, 1860. This family includes the longest species in the order Odonata, all of which as far as known breed exclu­ sively in phytotelmata as does its East African sister group Coryphagrion grandis Morton, 1924 (Corbet 1999: 145; Clausnitzer & Lindeboom 2002; Fincke 2005; Groeneveld et al. 2007). Final stadium larvae of Mecistogaster linearis (Fabricius, 1776), M. modesta Se­ lys, 1860, M. ornata Rambur, 1842, M. asticta Selys, 1860, Microstigma rotunda­ tum Selys, 1860, M. maculatum Hagen in Selys, 1860, Megaloprepus caerulatus (Drury, 1782), and Pseudostigma aberrans Selys, 1860 have been described so far (Calvert 1911; Novelo Gutierrez 1993; Ramirez 1995, 1997; Westfall & May 1996; Hedstrom & Sahlen 2003; Sahlen & Hedstrom, 2005; Lencioni 2006; De Marmels 2007; Neiss et al. 2008). Mecistogaster is the most speciose genus within Pseudostigmatidae including 10 species, three of which are recorded from Argentina: M.

    ARGENTINA’S INFORMAL ECONOMY: A CASE STUDY OF PATRIA GRANDE UPON THE INFORMAL TEXTILE INDUSTRY A Thesis submitted to the Faculty of the Graduate School of Arts and Sciences of Georgetown University in partial fulfillment of the requirements for the degree of Masters of Arts in Development Management and Policy By Anna Porembka, B.A. Washington, DC May 1, 2013 Copyright 2013 by Anna Porembka All Rights Reserved ii ARGENTINA’S INFORMAL ECONOMY: A CASE STUDY OF PATRIA GRANDE UPON THE INFORMAL TEXTILE INDUSTRY Anna Porembka, B.A. Thesis Advisor: Matthew Carnes, S.J. ABSTRACT In order to strengthen their economic positions, developing nations like Argentina have produced laws aimed at salient informal manifestations. Argentina’s 2005 law “Patria Grande” sought to answer public outcry after a deadly fire exposed the inhumane conditions of illegal textile workers. What is the relationship between public policy and informality, and what legal, economic, and social characteristics identify the informal economy generally, and in Argentina specifically? What is the historical foundation of Argentine informality, and how has it behaved in the 21st century? Finally, how did Patria Grande develop, and what lessons can we learn from its results? By taking a public policy approach to informality, this study unravels the current characteristics and the historical roots of Argentina’s institution of informality. Three empirically recognized factors of informality are applied in a MIMC model and discussed with regard to Argentina’s history and present condition. These indicators support that, since the 2001-2 crisis, the Argentine informal economy appears to be shrinking, but at a decreasing rate.

  • Nasal Cartilages, Hyobranchial Apparatus, Larynx, and Glottal Tubes in Four Species of Hydropsini (Serpentes: Dipsadidae: Xenodontinae)
    64 (1): 103 – 111 © Senckenberg Gesellschaft für Naturforschung, 2014. 16.5.2014 Nasal cartilages, hyobranchial apparatus, larynx, and glottal tubes in four species of Hydropsini (Serpentes: Dipsadidae: Xenodontinae) Diego Omar Di Pietro 1, Leandro Alcalde 1, 2 & Jorge Daniel Williams 1 1 Sección Herpetología, División Zoología Vertebrados, Facultad de Ciencias Naturales y Museo (UNLP), Paseo del Bosque s/n (CP1900), La Plata, Buenos Aires, Argentina — 2 Sección Herpetología, Área Sistemática, Instituto de Limnología Dr. R.

Published online at www.senckenberg.de/vertebrate-zoology on 30.iv.2014. Abstract Tribe Hydropsini (Serpentes: Dipsadidae: Xenodontinae) consists of three genera of aquatic snakes, Helicops, Hydrops, and Pseudoeryx, in which cartilaginous cranial features have been poorly studied. We here describe the nasal cartilages, hyobranchial apparatus, larynx, and glottal tubes in four representative Hydropsini species, compare them with species from other Dipsadidae tribes, and discuss our results in the context of the adaptation to the aquatic and fossorial habit. The studied species possess two nasal features that deviate from the pattern of nasal cartilages known in other aletinophidian and caenophidian snakes: (1) a cartilaginous connection between the lamina transversalis anterior and the concha of the Jacobson´s organ, and (2) a small rostral projection of the planum anteorbitale, which probably represents a reduced anterior maxillary process. Two putative synapomorphic features may be supporting the monophyly of Hydropsini: (1) a short inferior median eminence of the cricoid cartilage, and (2) a large processus entoglossus of the hyobranchial apparatus.

  • 2015 Grain and Feed Annual Argentina
    THIS REPORT CONTAINS ASSESSMENTS OF COMMODITY AND TRADE ISSUES MADE BY USDA STAFF AND NOT NECESSARILY STATEMENTS OF OFFICIAL U.S. GOVERNMENT POLICY Required Report - public distribution Date: 4/1/2015 GAIN Report Number: Argentina Grain and Feed Annual 2015 Approved By: Melinda Sallyards Prepared By: Ken Joseph Report Highlights: Argentine wheat production for crop 2015/16 is forecast down at 12 million tons due to a projected smaller planted area. The current policy limiting exports negatively impacts wheat prices and produces significant marketing problems. Barley production, which has no marketing restrictions, is projected up at 3.5 million tons. Corn production in marketing year 2015/16 is forecast to drop at 20 million tons. Under current policies and market conditions corn is the crop which demands the highest investment but provides the worst profitability. Sorghum production in 2015/16 is expected up at 4.5 million tons. Argentina is now eligible to export to China, bringing expectations of better prices. Rice production is forecast at 1.5 million tons (rough production), with a practically unchanged planted area. GENERAL High inflation, an over-valued peso, limited financing and government policies have all combined to force producers to reduce plantings of wheat and corn for the 2015/16 crop year. Barley and sorghum, which are not subject to government export restrictions, are expected to increase production. Sorghum has also benefited from an Argentina-China agreement that has opened up Chinese markets for Argentine product. In 2014/15 despite the decrease in inputs used by producers given the financial difficulties facing the sector, production has increased compared to the previous year.

Libertad 5470 (3400) Corrientes, Argentina *Unidad de Ecología de Reservorios y Vectores de Parásitos, Departamento de Ciencias Biológicas, Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, Buenos Aires, Argentina An entomological and serological survey was performed in three localities of the Department of Concepción, Province of Corrientes, Argentina in 1998 and 1999, to identify triatomines species involved in domestic and wild transmission of Chagas disease. Triatomines were collected by man/hour capture in 32 houses randomly selected and 44 nearby outdoor ecotopes. Trypanosoma cruzi infection in triatomines was assessed by direct microscopic observa- tion (400x) of feces and polymerase chain reaction. Serological techniques used for people were Indirect Hemagglu- tination Test and Indirect Fluorescent Test. Triatomines were collected in 28.1% of the houses and 31.8% of the wild biotopes. Triatoma infestans (Klug 1834) was exclusively found indoors and T. cruzi infected 60% of them. Triatoma sordida (Stål 1859) was mainly found in extradomestic ecotopes where trypanosome infection rate reached 12.7%. Serological study of 98 local people showed that 29.6% were seroreactive; most of their houses were closed to wild biotopes colonized by T. sordida. Results indicate that there is an active T.
