    Diabrotica virgifera virgifera LeConte in confrontation mood : simultaneous geographical and host spectrum expansion in southeastern Slovenia

    No full text
    Diabrotica virgifera virgifera LeConte, in its original North American habitat also known as western corn rootworm beetle, actively continues its expansion to new territories and uses Homo sapiens as its prime vector. It took only 15 years to spread to and occupy the southeastern and central parts of Europe, so far with the exception of Denmark where it has not been documented as of 2007. Economic thresholds have been reached and surpassed only in Southeast European countries like Slovakia, Hungary, Serbia, Eastern Croatia, Romania and Northern Italy. But both, the area affected and the severity of symptoms are increasing. Model calculations by a number of authors (Baufeld & Enzian, 2005 a and b; Hongmei Li & al. 2006, CLIMEX model) indicate a definitive propensity of D. v. virgifera to expand its currently occupied territory to regions with moderate temperatures and Zea mays cultivation. East Africa and Eastern Asia are included in the list of potential candidates for future inadvertent introduction. In most discussions it is tacitly and erroneously assumed that Z. mays is the only or the only important host of D. v. virgifera. Our recent observations in Eastern Slovenia on the oil pumpkin Cucurbita pepo indicate, however, that this simplifying assumption is notlonger strictly valid. It has to be modified in light of new evidence. Here, we report a few field experiments conducted in August of 2006 clarifying the host status of C. pepo in a European country.Diabrotica virgifera virgifera LeConte (Coleoptera: Chysomelidae), im deutschsprachigen Raum als Westlicher Maiswurzelbohrer bekannt, ist ein von der Neuen Welt nach Europa eingeschleppter Schädling. Er gelangte in mindestens drei Einwanderungsschüben, die durch molekulargenetische Untersuchungen unterscheidbar sind, nach Europa. Innerhalb der letzten eineinhalb Jahrzehnte wurde, mit Ausnahme von Dänemark, die gesamte Fläche Südost- und Zentraleuropas vom Käfer besiedelt. In mehreren osteuropäischen Ländern ist die ökonomische Schadensschwelle bereits überschritten. Bis 2006 galt Zea mays als einzige bekannte europäische Wirtspflanze. Allerdings deuten neueste Beobachtungen in Ostslowenien vom August 2006 auf kleine Zahlen von Käfern am Ölkürbis Cucurbita pepo und damit auf eine Ausdehnung des Wirtsspektrums von D. v. virgifera hin. Der Käfer tritt in kleinen Zahlen als Besucher von Ölkürbisblüten mit einer Häufigkeit von 0,1 % auf. Er ist aber auch in geringer Häufigkeit in Kairomon- und Pheromonfallen in Ölkürbisfeldern südlich von Gaberje in Ostslowenien anzutreffen. Dieses Ergebnis stellt den zukünftigen Wert des Fruchtwechsels in Frage, der bisher als eine der wirksamsten und nachhaltigsten Methoden des integrierten Pflanzenschutzes galt

    Memoria, historia y psicoanálisis: Reflexiones en torno del malentendido Ricoeur-Lacan

    No full text
    El trabajo se inicia con el relato histórico del desencuentro entre Ricoeur y Lacan en los años 60. Luego, presenta la comprensión de la memoria en La memoria, la historia, el olvido de Paul Ricoeur, en la perspectiva de los rendimientos que Ricoeur hace producir al psicoanálisis en su consideración de la memoria impedida y del olvido. Aborda, en tercer lugar, las críticas que algunos lacanianos dirigieron, en diversos momentos, a la interpretación ricoeuriana del psicoanálisis. Finalmente, y con apoyo en este paso intermedio, intenta precisar cuáles han sido las consecuencias de aquel desencuentro para la comprensión ricoeuriana del papel de la historiografía.Fil: Leconte, Mariana.

    Tribe Erotini LeConte, 1881 Distribution. The Erotini are distributed in the Palaearctic, Nearctic, and Oriental (northern part only) realms (Masek et al., 2018; Kazantsev, 2020). Fossil taxa of these groups have been recorded from Baltic and Rovno amber.Published as part of Kazantsev, Sergey V. & Bocak, Ladislav, 2022, New genus of erotine net-winged beetles, Damzenium gen. nov.

    Hesperobaenus rufipes LeConte, 1863 (Fattig 1937; Bousquet 2002b) (Fig. 5B, D) Habitat and Biology: A widespread eastern species, H. rufipes is found under bark of hardwood trees (Acer, Carya, Fagus, Quercus) where it eats fungal hyphae, probably mostly Fungi Imperfecti (see Justis 2009). All examined records are from the months of December to May, so it is possible the adults are winter-active.Published as part of Mcelrath, Thomas C. & Mchugh, Joseph V., 2018, Undocumented beetle diversity in the Southeastern United States: a case study of the minute clubbed beetles (Coleoptera: Monotomidae), pp. 127-140 in Zootaxa 4472 (1) on page 135, DOI: 10.11646/zootaxa.4472.1.6, http://zenodo.org/record/144006
