Abstract:

The site of ancient Eleutherna is located in the regional unit of Rethymnon, around 25 km away from the town of that name, in the region of Mylopotamos, northwest of Mount Ida. Hills characterise the archaeological zone of the site, deeply cut through by two streams, to the east and to the west. It is a naturally fortified site, blessed with rich vegetation. Systematic excavations in Eleutherna by the University of Crete began in 1985. The whole site was divided into three Sectors. The eastern and western sides of one of these hills, Pyrgi, have been excavated (Sectors I and III, respectively)

Abstract:

The three golden tablets from Pyrgi, an ancient site on the coast of the Tyrrhenian Sea, in Lazio, Italy, known as Laminae Pyrgienses discovered in 1964 is the only bilingual Etruscan text of which one tablet is inscribed in Phoenician and the other two in Etruscan. Hoped to be a kind of Etruscan ‘Rosetta Stone’ with identical texts in two languages, the initial enthusiasm turned into disappointment when the researchers realized that the texts were incongruent with each other, the Etruscan being rather paraphrased from the Phoenician, or vice versa. Since then a number of attempts at its decip

Il contributo esamina gli aspetti linguistici dell’iscrizione e individua in uno stesso ambito territoriale e cronologico – Pyrgi, fine del VI – inizi del V secolo a.C. – la compresenza di due appellativi leggermente distinti (Uni e Unei-) per designare la stessa divinità. L’evidenza va probabilmente collegata all’esistenza di due tradizioni scribali e linguistiche distinte, di cui la variante Unei- sembrerebbe rappresentare una forma più “enfatica” destinata ad essere infine riassorbita in Uni.

Abstract:

The gold tablets from Pyrgi, studied many times for linguistic and philological reasons, constitute a clear example of religio-social ideology at work. They deploy their themes (the goddess, the ruler, the sanctuary) in a way that helps create the symbolical universe of the readers, in whose world it is inscribed that these things are part of a greater, orderly whole. The texts are here analysed from the points of view of ideology, power and religious tendency, as parts of the system of religious symbolism that they seek to legitimize. Rhetorical points are also touched upon, as well as the fu

Abstract The Etruscan goddess Catha has long been regarded as a solar deity. G. Thulin (1906) was one of the first to characterize Catha as a solar deity based on inscriptions referencing Catha on a mirror from Orbetello and on the Piacenza Liver. Although Thulin’s interpretations of these inscriptions have been challenged, the goddess Catha is still perceived to be a solar deity. Evidence from the goddess’s cult site at Pyrgi, where she was known as Kautha, inscriptions on artifacts that bear her name, and bucchero vessels that appear to display the goddess as a potnia theron suggest that the

Summary My paper aims to clarify the subsequent steps of Rome’s encroachment on Etruria in the aftermath of the Pyrrhic War. As is well known, the Latin colony of Cosa was founded in 273 BC on the Tyrrhenian coast to the north of Vulci; moreover, in the years 264–245 BC, four citizen colonies were founded on the Caeretan coast, namely Castrum Novum, Pyrgi, Alsium and Fregenae. Unfortunately, it is not easy to reconstruct precisely what the Roman movements in Etruria were, or how the Etruscans reacted to them. Above all, it is difficult to determine whether (and to what extent) a colonial found

These mutations allowed the intracellular pools of cytidine and uridine nucleotides to be manipulated by the composition of the growth medium.

SUMMARY DNA-binding repressor proteins that govern transcription initiation in response to end products generally regulate bacterial biosynthetic genes, but this is rarely true for the pyrimidine biosynthetic (pyr) genes. Instead, bacterial pyr gene regulation generally involves mechanisms that rely only on regulatory sequences embedded in the leader region of the operon, which cause premature transcription termination or translation inhibition in response to nucleotide signals. Studies with Escherichia coli and Bacillus subtilis pyr genes reveal a variety of regulatory mechanisms. Transcripti

AbstractIn a survey of predaceous phytoseiid mites from 65 apple blocks in the Hood River Valley, Oregon, Metaseiulus occidentalis (Nesbitt) and Typhlodromus pyri Scheuten were the principal species present. Metaseiulus occidentalis predominated over T. pyri by a ratio of about 2:1 in 1984 mites collected during 1985. In experimental, commercial, and integrated pest management blocks, M. occidentalis was present alone or predominated over T. pyri in up to 88% of the blocks, whereas T. pyri occurred alone or predominated in up to 20% of the blocks. Both species occurred in near equal proportion

Abstract:

AbstractAdults of the leaf weevil Phyllobius pyri (L.) (Coleoptera: Curculionidae) feed on a wide variety of broadleaved trees and occasionally cause severe defoliation in newly established farm woodlands. There is little information, however, on the relative susceptibility of different tree species to damage or on the habitat associations of adults and larvae of P. pyri, which might indicate the conditions that predispose trees to attack. Captures of adult P. pyri in emergence and flight traps in the current study indicated population densities in grassland of 0.5–6.4 adults per m2 at emergen

Abstract:

Knowledge about phytoseiid species associated with vines is a preliminary step in the development and implementation of integrated management strategies against phytophagous mites such as Panonychus ulmi. The aim of this study was to perform a comparative survey of phytoseiids present in abandoned, organically managed, and conventionally managed vineyards, as well as to compare ecological indices in these production systems. Samplings were conducted between July and September 2017 in vineyards situated in the Subregions of Lima and Cávado, the Vinho Verde region. A total of 50 leaves/vineyard

Abstract:

Phacidiopycnis washingtonensis and P. pyri cause speck rot and Phacidiopycnis rot on apple and pear, respectively. Infection occurs in the orchard and remains latent, and symptoms appear after months of storage. Decay management relies on orchard sanitation and pre- and postharvest fungicides. In a 2017 survey, speck rot accounted for 6.4% of apple decay in central Washington, whereas Phacidiopycnis rot accounted for 3.9 and 6.7% of total pear decay in Washington and Oregon, respectively.

Abstract:

There are many methods to detect plant pests and diseases, but they are primarily time-consuming and costly. Computer vision techniques can recognize the pest- and disease-damaged fruits and provide clues to identify and treat the diseases and pests in their early stages. This study aimed to identify common pests, including the apple capsid (Plesiocoris rugicollis)/AC, apple codling moth (Cydia pomonella)/ACM, Pear lace bug (Stephanitis pyri)/PLB, and one physiological disease-apple russeting/AR in two cultivars, Golden Delicious and Red Delicious, using the digital image processing and sparse

Polymerase chain reaction (PCR) tests were performed on psyllids captured from the orchards with the highest occurrence of these insects. The DNA extracted from pairs of psyllid individuals was analysed by nested PCR (R16F2n/R2-fU5/rU3) and restriction fragment length polymorphism method (RFLP) (RsaI, BfmI).

In Samochvalovichi, Belarus, apple and pear tree root samples were examined for the presence of phytoplasmas using a universal 16S rDNA-based PCR assay. Out of 27 tested apple trees, 23 were found to be infected by ‘Candidatus Phytoplasma mali’ and 46 out of 58 pear trees were positive for the presence of ‘Ca. P. pyri.’ Species were identified by sequence analysis of the 16S rDNA amplicons. The molecular diversity of the phytoplasma isolates was examined by analysis of an hflB gene using single-strand conformation polymorphism (SSCP) and sequence analysis. Therefore hflB gene amplicons from ‘C

Abstract Adult males and larvae of sesiids were monitored in ten (1989–1991), five (2000) and two (2004) Quebec apple orchards. Multi Pher III traps baited with 99.1% Z, Z-3, 13-octadecadienyl acetate and 0.9% Z, E plus E, Z-3, 13-octadecadienyl acetate were used for adults, and trunk sampling was used for larvae. Synanthedon scitula, S. pyri, Podosesia syringae, S. acerrubri, S. fulvipes, S. exitiosa, S. acerni and Sesia tibialis males were captured between 1989 and 1991. Only 5 of the 347 adults of the S. scitula/pyri complex captured in 2000 belonged to S. pyri.

AbstractPear decline, induced by the phytoplasma 'Candidatus Phytoplasma pyri', transmitted by pear psyllids, is one of the most devastating diseases on Pyrus communis in Europe and North America. Investigations of pear psyllids in 4 pear orchards in lower Austria showed the presence of Cacopsylla pyri, C. pyricola and C. pyrisuga at all locations. PCR analyses revealed overall phytoplasma infection rates for C. pyri of 5.4%, for C. pyricola, of 4.6%, for C. pyrisuga remigrants of 9.6% and for C. pyrisuga emigrants of 0%.
