Insects found in the nests of Anumbius annumbi (Vieillot) [Aves: Furnariidae] from the provinces of Buenos Aires, Santa Fe, Entre Ríos, and La Pampa (Argentina) were studied. A total of 20 nests was sampled every 21 days in Buenos Aires, together with the insects found under ritidome of Eucalyptus in the same area. Samples from nests were divided by seasons: end of summer [nest 1]; autumn [nests 2 to 6]; winter [nests 7 to 12]; spring [nests 13 to 16]; summer [nests 17 to 19], and beginning of autumn [nest 20]. A total of 92 species of insects was found, of which only 36 species had been previously reported in the literature from 1943 until 2005. Additional nests were sampled from Santa Fe (3 nests), Entre Ríos (1 nest), and La Pampa (4 nests). Species richness, abundance and diversity per nest are given and discussed. Insects in birds´nests are classified according to their functional guilds (predators; hematophages and parasitoids; detritivores; phytophages and fungivorous); degree of permanence in the nests (temporal inhabitants [hibernants]; permanent inhabitants; accidentals and/or occasionals). Mortality among the insect fauna inside the nests and other dead insects found inside nests, probably prey remains, are cited. The insect fauna under the ritidome of Eucalyptus permits establishment of a habitat gradient: species only found in the nests, species mainly found in the nests and rarely under the ritidome, species found both under the ritidome and in the nests, species mainly found under ritidome and seldom in the nests, and species only found under the ritidome. Comments and remarks are made on selected taxa lacking or with limited biological data. The microhabitat in the tunnels of Ctenomys [Rodentia] is compared with the birds’nests regarding its similar insect fauna. Inquiline birds and mammals are also mentioned.

From 1912 until the late 1920s Argentina faced an agrarian social and economic crisis of proportions unprecedented in the republic's history. Trapped between unstable prices and the exactions of landlords, thousands of tenant farmers organized, went on strike, and at times sabotaged agricultural production. This unrest swept across the cereal belt, a 160,000,000-acre zone of extremely fertile soil in the provinces of Santa Fe, Entre Ríos, Córdoba, and Buenos Aires, and in the national territory of La Pampa. After 1919, rural unrest acquired new complexity when tens of thousands of landless workers employed by the tenant farmers began strike movements of their own. The purpose of the present article is to analyze the origins and characteristics of this rural upheaval and then to examine the responses to it formulated by the republic's national political leaders.

Argentine History

The battle of Pavón was one of the most important in Argentine history, for it symbolized the definitive union of all the Argentine provinces. This battle took place on the plains of Pavón, in the province of Santa Fe, on September 17, 1861. Most historians agree that it signalled the beginning of Argentina as a nation.For nearly a decade prior to this battle, Argentina had suffered from internal strife and division. On February 3, 1852, the forces of Justo José de Urquiza, Governor of the province of Entre Ríos, had overthrown the army of Juan Manuel de Rosas, the violent caudillo who had ruled the province of Buenos Aires with a heavy hand since 1829;1 during the greater part of his regime, Rosas had handled foreign affairs for all fourteen of the provinces of the Argentine Confederation. Rosas was forced into exile in England. As a matter of course, Argentine then looked to Urquiza for leadership.

Las inundaciones y sequías son una constante en la Región Pampeana (Argentina). Casi todos los años uno de estos eventos hidrológicos extremos tiene lugar y, a veces, ambos. La evolución temporal del exceso de agua en el suelo, durante sesenta años se analiza en nueve estaciones meteorológicas localizadas en importantes áreas cuyos usos del suelo tienen impacto económico y social. Ellas se ubican en las provincias de Córdoba, Santa Fe, Entre Ríos, La Pampa y Buenos Aires. Los datos meteorológicos diarios fueron provistos por Servicio Meteorológico Nacional para el período 1951- 2010. El modelo de balance de agua en el suelo fue el utilizado por Forte Lay et al. que está basado en el de Thornthwaite-Mather y la evapotranspiración diaria de referencia normal media fue estimada con la fórmula de Penman-Monteith. En el presente trabajo al parámetro exceso de agua en el suelo se lo utiliza como indicador del riesgo de inundación. La metodología Makesens se usó para el análisis estadístico, el mismo se basa en el test no paramétrico de Mann-Kendall para el estudio de la tendencia y el método no paramétrico Sen para su magnitud. Todas las estaciones analizadas mostraron diferente evolución del exceso de agua en el suelo y experimentaron riesgo de inundación en algún momento del período estudiado.

El ciervo de las pampas, posee una amplia distribución en los ambientes abiertos de Sudamérica, especialmente pastizales y sabanas. La distribución del ciervo de las pampas en Argentina durante el siglo XIX abarcaba las provincias de Formosa, Salta, Chaco, Santiago del Estero, Santa Fe,Córdoba, Corrientes, Entre Ríos, Buenos Aires, La Pampa, San Luis, sur de Mendoza y norte de Río Negro. En los primeros años del siglo XX, y como resultado del avance de la frontera agropecuaria, esta distribución se restringió al sur de la provincia de San Luis, La Pampa, sur de Entre Ríos, Corrientes, norte de Santa Fe y en la provincia de Buenos Aires a las Sierras Australes y el área costera de Bahía Samborombón y Monte Hermoso. Actualmente la distribución del ciervo de las pampas en la Argentina se limita a cuatro núcleos poblacionales. Dos pertenecientes a la subespecies O. b. leucogaster, en el noreste de la provincia de Corrientes (Departamentos de Ituzaingó, Santo Tomé, San Martín y General Alvear) y en el noroeste de Santa Fe en la región denominada como “Bajos Submeridionales”. En cuanto a la subespecie austral, O.b. celer, habita un área de pastizales relictuales del sureste de la provincia de San Luis, y la zona costera de Bahía Samborombón, en la cual se desarrolló el presente trabajo de tesis.

AbstractDistribution and epidemiological patterns of sunflower chlorotic mottle virus (SCMoV) in sunflower (Helianthus annuus L.) growing areas in Argentina were studied from 2006 to 2017. The virus was detected exclusively in the Pampas region (Entre Ríos, Santa Fe, Córdoba, La Pampa and Buenos Aires provinces). Phylodynamic analyses performed using the coat protein gene of SCMoV isolates from sunflower and weeds dated the most recent common ancestor (MRCA) back to 1887 (HPD95% = 1572-1971), which coincides with the dates of sunflower introduction in Argentina. The MRCA was located in the south of Buenos Aires province and was associated with sunflower host (posterior probability for the ancestral host, ppah= 0.98). The Bayesian phylodynamic analyses revealed the dispersal patterns of SCMoV, suggesting a link between natural host diversity, crop displacement by human activities and virus spread.

Breeding Seasons

Nest-boxes used by the White-rumped Swallows, Tachycineta leucorrhoa leucorrhoa (Vieillot, 1817) [Aves: Hirundinidae] were sampled during two consecutive breeding seasons in the province of Buenos Aires, Argentina. A total of 11 taxa of insects were found in the nests of this species: 10 in the order Coleoptera: Coccinellidae [Cycloneda ancoralis; Scymnus sp.]; Cavognathidae [Cavognatha sp.]; Aphodiidae [Aphodius sp.]; Dermestidae [Trogoderma sp.; Dermestes maculatus]; Histeridae [Saprinus sp.]; Carabidae [Notaphus fisheri; Bradycellus sp.]; Elateridae [undetermined sp.]; Undetermined family (larvae), and one in the order Hemiptera: Cimicidae [Acanthocrios furnarii]. These insects were differentiated from prey remains, sometimes entire specimens. The species of Cimicidae appeared in two different nests built in the same box by the same female. The composition of the insect fauna found in swallows’ nests is similar to those in natural birds’ nests from the same province, but the diversity, abundance and richness in swallows’ nests inside boxes were lower.

Insects found in birds’ nests from Argentina. Furnarius rufus (Gmelin, 1788) (Aves: Furnariidae) and their inquiline birds, the true hosts of Acanthocrios furnarii (Cordero & Vogelsang, 1928) (Hemiptera: Heteroptera: Cimicidae)

Hematophagous Insect

The nest of Furnarius rufus (Gmelin, 1788) [Aves: Furnariidae] is a domed mud structure, with a partition separating the breeding chamber from the outside. In general each couple builds one nest per year, but each nest is used for one clutch or two consecutive clutches in the same breeding season. Some nests can remain in the field for 2 or 3 years, but some had a longer permanence (up to more than 8 years). Thus the nests are widely used by other vertebrate inquilines. Insects found in nests of F. rufus mentioned in the literature belong to Coleoptera [Chrysomelidae (1 sp.), Histeridae (1 sp.)], Hemiptera [Cimicidae (1 sp.), Reduviidae: Triatominae (1 sp.)], Hymenoptera [Apidae: Meliponinae (1 sp.)], and Diptera [Muscidae (2 spp.)]. A total of 9 orders, 35 families (two unidentified), and 67 species of insects (including 14 identified to genus and 10 undetermined), were found in 251 nests of F. rufus sampled in Argentina (Chaco [6], Córdoba [14], Santa Fe [2], Entre Ríos [7], San Luis [1], La Pampa [12], and Buenos Aires [209]). The most abundant species was one hematophagous insect, Acanthocrios furnarii (Cordero & Vogelsang, 1928) [Hemiptera: Cimicidae], an exclusive parasite on the inquiline birds. Agelaioides badius badius (Vieillot, 1819) [Aves: Icteridae], Sicalis flaveola pelzelni Sclater, 1872 [Aves: Emberizidae], and Troglodytes aedon Vieillot, 1809 [Aves: Troglodytidae] are new hosts of A. furnarii. Progne chalybea (Gmelin, 1789) [Aves: Hirundinidae] was found for the first time infested by A. furnarii inside the nests of F. rufus. The insects in the nests of Furnarius cristatus Burmeister, 1888, and those of P. domesticus, Progne sp., S. f. pelzelni, and T. aedon outside the nests of F. rufus were also investigated. Some ticks (Acarina: Argasidae, Ixodidae) found in the nests of F. rufus and P. domesticus are mentioned.

A New Species

The family Passandridae (Coleoptera: Cucujoidea) in Argentina and adjacent countries is reviewed. A total of 13 species are recorded from Argentina: Catogenus asper Ślipiński, 1989, Catogenus castaneus (Perty, 1834), Catogenus cylindricollis (Lacordaire, 1854), Catogenus decoratus Newman, 1839, Catogenus depressus Ślipiński, 1989, Catogenus gracilicornis Ślipiński, 1989, Catogenus lebasi Guérin-Méneville, 1844, Catogenus longicornis Grouvelle, 1874, Passandra fasciata Gray in Griffin, 1832, Taphroscelidia humeralis (Grouvelle, 1916), Taphroscelidia semicastanea (Reitter, 1876), and Taphroscelidia sp. (probably a new species, not described here). New provincial records are given for C. castaneus (Salta; La Rioja; Santiago del Estero; Córdoba; Corrientes; Buenos Aires), C. cylindricollis (Salta; Misiones; Chaco; Santa Fe; Entre Ríos), C. gracilicornis (Catamarca; Buenos Aires), C. longicornis (Salta; Tucumán; Catamarca; Chaco; La Rioja; Entre Ríos; Buenos Aires), P. fasciata (Córdoba; Santa Fe; Mendoza; Buenos Aires), T. humeralis (Salta; Catamarca; La Rioja; San Luis; Santa Fe; Corrientes; Entre Ríos), T. semicastanea (Salta; Catamarca; Corrientes; Entre Ríos), and Taphroscelidia sp. (Corrientes). Four new records are given for Paraguay: C. castaneus, C. cylindricollis, C. longicornis, and Taphroscelidia sp. Monthly and seasonal occurrence of adults is summarized and discussed. Adults of Passandridae emerged from 25 plant species infested with a total of 62 species of Cerambycidae (Coleoptera). Their host specificity is discussed in connection with their wide geographic distributions, which are apparently unrelated to a particular biogeographic province.
