The Oriental Red Mite, Eutetranychus orientalis (Klein) (Acarina: Tetranychidae), in Australia
The oriental red mite, Eutetranychus orientalis, an important pest of citrus and other crops in many parts of the world, has been in Queensland for at least 30 years. We review Australian collections of oriental red mite, clarify confusion over its name and pest status, discuss its potential biological control agents, and provide a key to differentiate known Australian species of Eutetranychus and the African red mite, E. africanus (Tucker)
Orbital evolution of P\v{r}\'{i}bram and Neuschwanstein
The orbital evolution of the two meteorites P\v{r}\'{i}bram and
Neuschwanstein on almost identical orbits and also several thousand clones were
studied in the framework of the N-body problem for 5000 years into the past.
The meteorites moved on very similar orbits during the whole investigated
interval. We have also searched for photographic meteors and asteroids moving
on similar orbits. There were 5 meteors found in the IAU MDC database and 6
NEAs with currently similar orbits to P\v{r}\'{i}bram and Neuschwanstein.
However, only one meteor 161E1 and one asteroid 2002 QG46 had a similar orbital
evolution over the last 2000 years.Comment: 7 pages, 2 figures, 3 table
US hegemony and the origins of Japanese nuclear power : the politics of consent
This paper deploys the Gramscian concepts of hegemony and consent in order to explore the process whereby nuclear power was brought to Japan. The core argument is that nuclear power was brought to Japan as a consequence of US hegemony. Rather than a simple manifestation of one state exerting material ‘power over' another, bringing nuclear power to Japan involved a series of compromises worked out within and between state and civil society in both Japan and the USA. Ideologies of nationalism, imperialism and modernity underpinned the process, coalescing in post-war debates about the future trajectory of Japanese society, Japan's Cold War alliance with the USA and the role of nuclear power in both. Consent to nuclear power was secured through the generation of a psychological state in the public mind combining the fear of nuclear attack and the hope of unlimited consumption in a nuclear-fuelled post-modern world
Genome-Wide Association Study in BRCA1 Mutation Carriers Identifies Novel Loci Associated with Breast and Ovarian Cancer Risk
BRCA1-associated breast and ovarian cancer risks can be modified by common genetic variants. To identify further cancer risk-modifying loci, we performed a multi-stage GWAS of 11,705 BRCA1 carriers (of whom 5,920 were diagnosed with breast and 1,839 were diagnosed with ovarian cancer), with a further replication in an additional sample of 2,646 BRCA1 carriers. We identified a novel breast cancer risk modifier locus at 1q32 for BRCA1 carriers (rs2290854, P = 2.7×10-8, HR = 1.14, 95% CI: 1.09-1.20). In addition, we identified two novel ovarian cancer risk modifier loci: 17q21.31 (rs17631303, P = 1.4×10-8, HR = 1.27, 95% CI: 1.17-1.38) and 4q32.3 (rs4691139, P = 3.4×10-8, HR = 1.20, 95% CI: 1.17-1.38). The 4q32.3 locus was not associated with ovarian cancer risk in the general population or BRCA2 carriers, suggesting a BRCA1-specific associat
Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures
Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo
Revision of the Australian ascidae (Acarina : Mesostigmata)
Ascid mites are an important component of the predatory meiofauna in soil, on vegetation, and in association with other animals, yet the Australian fauna is almost unknown. At least 15 genera of ascid mites occur in Australia, of which 14 genera and 26 species are treated in this paper. Four of these genera (Gamasellodes, Hoploseius, Platyseius, Xenoseius) are here recorded from Australia for the first time. Six new species are described [Antennoseius (Antennoseius) lobochelus, sp. nov., Arctoseius memnon, sp. nov., Gamasellodes plaire, sp. nov., Platyseius cupensis, sp. nov., Xenoseius elizae, sp. nov., and Zerconopsis pristis, sp. nov.], and six other species are reported from Australia for the first time [Arctoseius semiscissus (Berlese), Gamasellodes rectiventris Lindquist, Proctolaelaps aurora (Vitzthum), Proctolaelaps bickleyi (Bram), Proctolaelaps lobatus De Leon, and Protogamasellus massula (Athias-Henriot)]. Proctolaelaps nesbitti (Womersley) is removed from synonymy with P. pygmaeus (Müller). Lectotypes are designated for Proctolaelaps antennatus Karg and P. australis Stone. P. antennatus has wrongly been recorded from Australia, and is known only from New Zealand. The first observations of feeding behaviour of mites in the genera Iphidozercon, Xenoseius and Zerconopsis confirm that nematophagy is prevalent among soil Ascidae. Keys to the world genera and Australian species are provided. Protogamasellopsis Evans and Purvis is transferred to the Rhodacaridae, Tangarorellus Luxton to an unspecified family in the Rhodacaroidea, and Lindquistoseius Genis, Loots & Ryke to the Ologamasidae. Orolaelaps DeLeon is removed from synonymy with Melichares Hering. The following new synonymies are proposed: Arctoseius bicuspidatus Willmann, 1949 and Arctoseius limburgensis Nesbitt, 1954 = Arctoseius semiscissus (Berlese, 1892); Cheiroseius (Posttrematus) Karg, 1981 = Episeius Hull, 1918; Iphidozercon californicus Chant, 1963, Leioseius (Arctoseius) elegans Bernhard, 1963 and Iphidozercon variolatus Ishikawa, 1969 = Iphidozercon corticalis Evans, 1958; Garmania longipilis Chant, 1958 = Proctolaelaps aurora (Vitzthum, 1925); Proctolaelaps lewisi Garman & McGregor, 1956 = P. utahensis Chant, 1958; Lasioseius conviva var. laevisternus Berlese, 1916a = Proctolaelaps pygmaeus (Müller, 1859); Neojordensia lativentris Karg, 1982 = Africoseius areolatus Krantz, 1962
The occurrence of Varroa underwoodi (Acarina: Varroidae) in Papua New Guinea and Indonesia
The findings reported here contribute to what is currently known about the geographical distribution, host range and reproduction of the ectoparasitic mite, Varroa underwoodi. Female V underwoodi and their nymphal offspring were collected from sealed drone cells in Apis cerana colonies in Papua New Guinea (PNG), the Indonesian provinces of Java, Sulawesi and Irian Jaya, and the Indonesian islands of Biak and Yapen. Gravid female V underwoodi were also collected from newly capped drone cells in A nigrocincta colonies in Sulawesi. Adult female V underwoodi, showing no signs of reproduction, were collected from capped worker cells in A mellifera colonies in PNG. On the basis of morphological structures, the adult female V underwoodi specimens from PNG and Indonesia were indistinguishable from V underwoodi specimens described from other localities
