Note: Biotype status ofBemisia tabaci from various crops in Cyprus     

Vassilis A. Vassiliou  Christopher Jagge  Maria Grispou  Patricia V. Pietrantonio  Anastasia Tsagkarakou 《Phytoparasitica》2008,36(4):400-404

An extensive survey ofBemisia tabaci populations covering the southern half of the island of Cyprus was conducted in 2006 and 2007 in order to define the biotype status of the pest. Sampling was done both on protected and outdoor cultivations of vegetables and ornamental plants. Biotype identification was performed using molecular diagnostics based on the mitochondrial cytochrome oxydase I gene. Our results indicated the presence of only the biotype B in all 25 collections. http://www.phytoparasitica.org posting August 8, 2008.  相似文献   

A Computational Approach Based on GIS Technology for the Development of an Anthropogenic Emission Inventory of Gaseous Pollutants in Greece     

Konstantinos Markakis  Anastasia Poupkou  Dimitrios Melas  Paraskevi Tzoumaka  Maksinos Petrakakis 《Water, air, and soil pollution》2010,207(1-4):157-180

This paper describes a computational system developed for the compilation of an anthropogenic emission inventory of gaseous pollutants for Greece. The inventory was developed using a geographical information system integrated with SQL programming language to provide high temporal gridded emission fields for CO, NO₂, NO, SO₂, NH₃ and 23 non-methane volatile organic compounds (NMVOCs) species for the reference year 2003. Activity and statistical data from national sources were used for the quantification of emissions from the road transport, the other mobile sources and machinery sectors and from range activities using top-down or bottom-up methodologies. Annual emission data from existing national and European emission databases were also used. The emission data were spatially and temporally disaggregated using source-specific spatiotemporal indicators. On national scale, the road transport sector produces about 60% of the annual CO and NMVOC total emissions, with gasoline vehicles being the main CO and NMVOC emissions source. The road transport is responsible for approximately half of the higher alkanes and for more than half of the ethene and toluene emissions. The maritime sector accounts for about 40% of the annual total NO_x emissions, most of which are emitted by the international shipping subsector, whilst SO₂ is emitted mainly by the energy sector. The evaluation of the emissions inventory suggests that it provides a good representation of the amounts of gaseous pollutants emitted on national scale and a good characterisation of the relative composition of CO and NO_x emission in the large urban centres.  相似文献   

Evaluation and improvement of post-harvest performance of cut Viburnum tinus inflorescence     

Anastasios I. Darras  Anastasia Akoumianaki-Ioannidou  Nektarios E. Pompodakis 《Scientia Horticulturae》2010

Post-harvest performance of cut viburnum inflorescences was examined in the present study. Harvesting viburnum at three developmental stages resulted in significant differences on flower opening rate (FOR) and flower abscission rate (FAR), but not on vase life. Harvesting at Stage III (>50% open flowers) resulted in highest flower opening percentage, whereas harvesting at Stage I (10–30% open flowers) in significantly lower flower abscission percentage. Pulsing with 20 or 40 mg/l AgNO₃ for 24 h extended vase life by 1.6 and 1.9 days, respectively, compared to the controls. Furthermore, flower abscission was significantly reduced after 20 or 40 mg/l AgNO₃ treatments by 51 and 62%, respectively, compared to the controls. In contrast, vase solutions containing 100 mg/l DICA or 100 and 200 mg/l methanol did not extend vase life of cut viburnum inflorescences, but significantly reduced flower abscission. Vase solutions containing 1 or 2% (w/v) sucrose negatively affected vase life, flower opening and flower abscission of viburnum inflorescence. Post-harvest treatments with 1-MCP at 10 μl/l in an ethylene-free environment resulted in extension of vase life and in significant reduction of FAR and respiration rates compared to the controls. Vase life of 1-MCP treated inflorescences was increased by 4.2 days compared to the controls. FAR of 1-MCP treated inflorescences remained significantly lower from the second to the eighth day of the vase life period.  相似文献

Periodic administration of allopurinol is not effective for the prevention of canine leishmaniosis (Leishmania infantum) in the endemic areas     

Saridomichelakis MN  Mylonakis ME  Leontides LS  Billinis C  Koutinas AF  Galatos AD  Gouletsou P  Diakou A  Kontos VI 《Veterinary parasitology》2005,130(3-4):199-205

A total of 95 clinically healthy and seronegative for Leishmania infantum dogs, residing an area highly endemic for canine leishmaniosis (CL) and living an outdoor life-style, were split into positive and negative groups, and then were randomly assigned to receive allopurinol (n = 51; 20 mg/kg once daily), or placebo (n = 44) for 1 week per month, from April to November. Forty per cent (38/95) of these dogs were not reexamined and retested at the end of the trial for reasons unrelated to CL. None of the remaining 57 dogs exhibited the symptomatic form of the disease at the end of the 1-year follow-up period. Of the 15 allopurinol-treated dogs that were non-infected (negative PCR and tissue smear microscopy) at the beginning of the trial, 6 (40% P = 0.03) became PCR-positive, of which 3 became also seropositive, at the end of the observation period. In contrast, only 1 of 7 (14.3%) placebo-treated non-infected dogs became PCR positive at the same time point. Of the 19 allopurinol-treated dogs that were infected (PCR-positive) at the beginning of the trial, 18 (94.7%) remained PCR-positive and one (5.3%) seroconverted, at the end of the observation period. Of the 16 initially infected and placebo-treated dogs, 14 (87.5%) remained PCR positive, of which one (6.7%) also turned positive by tissue smear microscopy. Therefore, it is concluded that the use of allopurinol, at the daily dose of 20 mg/kg, for 1 week per month, during the period of sandfly activity, does not prevent the infection of non-infected dogs by L. infantum, and, also, does not help in the elimination of the parasite from dogs with asymptomatic infections.  相似文献   

The Effects of Seasonality in Estimating the C‐Factor of Soil Erosion Studies     

Thomas K. Alexandridis  Anastasia M. Sotiropoulou  George Bilas  Nikolaos Karapetsas  Nikolaos G. Silleos 《Land Degradation \u0026amp; Development》2015,26(6):596-603

Monitoring soil erosion risk is an important part of soil conservation practices. It is usually estimated with the Universal Soil Loss Equation, and the C‐factor (vegetation cover) is derived from optical satellite images. However, because of lack of data and resources, or in rapid assessments, C‐factor is estimated using one or a few satellite observations, despite being temporally variable according to plants' phenology. The aim of this work was to study the effect of seasonality in estimating C‐factor. This was achieved by demonstrating first that there is a difference when estimating soil erosion with Universal Soil Loss Equation at variable time steps in a year, namely once, seasonally and monthly. Using Moderate Resolution Imaging Spectroradiometer normalized difference vegetation index images and statistical analysis at subcatchment scale, it was shown that there is a significant difference when estimating mean annual soil loss with the aforementioned temporal options. The highest differences were observed between monthly and annual time steps. The second objective was to identify which is the optimum time to estimate C‐factor in a year. The results show that November, October and March are the optimum months for single image estimation of annual soil erosion. Statistical analysis with a random point dataset suggested that the spatial variability of the results was influenced by the land cover type, especially in areas with variable leaf cover where a single date estimation of C‐factor was not representative of the whole year, such as annual crops and deciduous trees.
