TESTS OF BIRD DAMAGE CONTROL MEASURES IN SUDAN, 1975

The Red-billed Quelea (Quelga quelaa), because of its widespread destruction of grain crops throughout its range in Africa, is one of the most studied and written about granivorous bird species. Less publicized are more local bird pests in Africa which may be equally Important. The Village Weaver, (Ploceus cucullatus), for example, is a pest in many countries, while some other Ploecids with limited destructive habits create local problems. Significant crop losses also occur where there are large populations of Golden Sparrows (Passer luteus), House Sparrows (Passer domesticus), Red Bishops (Euplectes oryx), Doves (Streptopelia spp.), Glossy Starlings (Lamprotornis chalybaeus), Parakeets (Psittacula spp.), and some waterfowl (Mackworth-Praed and Grant, 1952; Pans Manual No. 3, 1974; Park, 1974). Crop losses from local bird pests were reported in early February 1975 to the Sudan Plant Protection Bird Control Unit of the Ministry of Agriculture. A mechanized farm scheme in Khartoum North had large concentrations of Red Bishops roosting in maize and feeding on an early-maturing wheat variety (Mexicana). Small flocks of Golden Sparrows and House Sparrows also were present. Bird damage was clearly visible, especially at the corners and along the edges of the ripening wheatfields. Ground spraying with Queletox (60% a.1. Fenthion) on roosts of the Golden and House Sparrows was conducted along hedge rows of acacia (Acacia mellifera) located at the north end of the farm. Although the spray killed large numbers of roosting birds, damage con- tinued as the wheat matured. Pilot field trials were thus organized to test the effectiveness of other crop protection techniques. Because birds fed throughout many blocks of wheat which matured at different periods, it was felt that several different experiments could be conducted without Interfering with each other. The control techniques Included an acoustical repellent, a chemical repellent, a chemical frightening agent, and a trap. The experiments, conducted from February 7 through February 23, 1975, were not designed as an integrated control operation.

A new species of Trachycephalus (Amphibia, Anura, Hylidae) from the State of Goias, Brazil

A new species of Trachycephalus is described for the Cerrado biome of Goias, Brazil. Trachycephalus mambaiensis sp. nov. is distinguished from the other ten species of the genus by the skin co-ossified with the skull, heavy cranial ossification, frontoparietal that fails to articulate with squamosal, absence of a crista occipitalis and secreting glands of milky and viscous substances. The skull of the new species shows an intermediary condition between species of Trachycephalus with a well ossified skull (Casque-headed frogs) and those without cranial ossification.

NEW RECORD OF CALYPTRAEID HOSTS FOR THE PEA CRAB CALYPTRAEOTHERES GARTHI (FENUCCI, 1975) (DECAPODA, PINNOTHERIDAE) IN ARGENTINA

Calyptraeotheres garthi (Fenucci, 1975) is one of nine species of Pinnotheridae occurring in Argentina and the only species of that genus located in this region. This species can be found from the San Maths Gulf, Argentina to Rio Grande do Sul, Brazil where it lives in symbiotic association with limpets of the family Calyptraeidae. Currently, two species of limpets have been reported as hosts of this species: Crepidula protea (d'Orbigny, 1841) and Crepidula argentina Simone, Pastorino & Penchaszadeh, 2000. We report here four more species of limpets serving as hosts of C. garthi, namely Bostrycapulus odites Collin, 2005, Crepidula cachimilla Cledon, Simone & Penchaszadeh, 2004, Crepidula plana Say, 1822 and Trochita pileus (Lamarck, 1822). Thus, this pinnotherid appears to be, as others members of the family, a generalist symbiotic species since it dwells on almost all the potential limpet species reported for Argentina. However, there are notable differences in prevalence of C. garthi on each host, which suggest that the symbiont might prefer species of Crepidula over the others genera (Trochita and Bostrycapulus). Additionally, there exists an apparent relationship between host size and prevalence (e.g., Crepidula cachimilla, the limpet with the highest prevalence, is clearly larger than the others hosts). Perhaps it is premature to conclude that the size of the host might be of benefit for the symbiont, but it is a hypothesis worthy of being explored.

La escuela primaria de la minería en el Concejo de Aller (Asturias). Del primer franquismo al tardofranquismo: 1940-1975

[ES]Tras la derrota de la República española, la estructura educativa fue desmontada en toda España y sustituida por una escuela centrada en los valores religiosos y patrios propugnados por el régimen franquista. El libro de actas de la Junta Municipal de Educación Primaria de Aller es una fuente privilegiada, inédita hasta el momento, para analizar la organización educativa durante el extenso periodo analizado. Este documento atestigua asimismo la dimensión política franquista y tardofranquista y la situación socio-laboral, como evidencian los objetivos de este artículo. Dentro de los programas paternalistas, activos hasta 1970 inclusive, las compañías mineras ya habían creado centros escolares religiosos en Aller durante el primer cuarto del siglo XX. Sin embargo, la mayor parte de los hijos de los mineros recibieron su instrucción en las escuelas nacionales, afianzadas sobre los rígidos esquemas de obediencia y sumisión. La educación franquista se ha esforzado en perpetuar los cometidos sociales de niños y niñas por medio de una educación segregada y represiva.[EN]After the defeat of the Spanish Republic, rpublican educational structure in Spain was dismantled around the whole country and replaced by one focused on the religious and patriotic values espoused by the Franco regime. The minute book contains the local board’s agreements between 1940 and 1975, not only in terms of educational management, which are exposed along the aims of this article. The source used for this article, unpublished until now, has also facilitated the study of the political and social-labour paternalistic dimension during the long period of time analysed. Within the paternalistic programmes, active until and including 1970, mining companies had already established faith schools in Aller, but most of the miners’ children received their education in state schools entrenched in severe patterns of obedience and submission. The educational system within Franco’s regime has strived to perpetuate the social roles of girls and boys through single-sex education.
