New record of stored product pest Lepinotus reticulatus (Psocoptera: Trogiidae) from China: Identification through scanning electron microscopy and DNA barcode

The parthenogenetic psocid Lepinotus reticulatus Enderlein (Psocoptera: Trogiidae) is regarded as the common stored product pest in the world. This species has been identified as a new record in People's Republic (P.R) of China in this study. It was found in a sample of rice sweepings at grain storage in Lijiang, Yunnan, 2010. Decisive morphological characteristics of this new record species were described in detail and newly documented by scanning electron microscopy (SEM) micrographs. In the meantime, DNA barcode sequences of mtDNA COI of this geographical strain were tested and analyzed by neighbor-joining phylogenetic tree which showed that it was in the same sub-group with the U.S.A. stock. The origin of L. reticulatus and the necessity of continued comprehensive survey of stored product psocids were discussed.Key words: Lepinotus reticulatus, stored product pest, external morphology, scanning electron microscopy (SEM), DNA barcode, phylogenetic analysis

Cotton fabric coated with conducting polymers and its application in monitoring of carnivorous plant response

The paper describes the electrical plant response to mechanical stimulation monitored with the help of conducting polymers deposited on cotton fabric. Cotton fabric was coated with conducting polymers, polyaniline or polypyrrole, in situ during the oxidation of respective monomers in aqueous medium. Thus, modified fabrics were again coated with polypyrrole or polyaniline, respectively, in order to investigate any synergetic effect between both polymers with respect to conductivity and its stability during repeated dry cleaning. The coating was confirmed by infrared spectroscopy. The resulting fabrics have been used as electrodes to collect the electrical response to the stimulation of a Venus flytrap plant. This is a paradigm of the use of conducting polymers in monitoring of plant neurobiology.Web of Science164art. no. 49

Current Threats Of Rodents and Integrated Pest Management (IPM) for Stored Grain and Malting Barley

Synanthropic rodents belong to the worldwide dominant vertebrate pests occurring in agricultural and food industry environment. Rodents have enormous potential to cause multiple damages to human resources by feeding on crops and stored commodities and by their faecal and urine contamination. The latter is associated with a risk of transmission of pathogens into food and feed chain. In spite of its health and hygienic signifi cance the risk of faecal contamination of stored grain is often under-rated by store-keepers and farmers due to insuffi cient published summary information. Therefore in this overview, we summarised the relevant key-literature resources dealing with hazards associated with contamination of grain stores and food processing plants by rodents

Mitochondrial genome organization varies among different groups of the booklouse, Liposcelis bostrychophila: Poster

The booklouse, Liposcelis bostrychophila is an important stored pest worldwide. The mt genome of an asexual strain (Beibei, China) of the booklouse, L. bostrychophila, comprises two chromosomes; each chromosome contains approximate half of the 37 genes typically found in animals. The mt genomes of two sexual strains of L. bostrychophila, however, comprise five and seven chromosomes respectively; each chromosome contains one to six genes. To understand mt genome evolution in L. bostrychophila, we sequenced the mt genomes of six strains of asexual L. bostrychophila collected from different locations in China, Croatia and USA. The mt genomes of all of the six asexual strains of L. bostrychophila collected in China, Croatia and USA have two chromosomes. Phylogenetic analysis of mt genome sequences divided nine strains of L. bostrychophila into four groups. Each group has a distinct mt genome organization and substantial sequence divergence (48.7-87.4%) from other groups. Furthermore, the seven asexual strains of L. bostrychophila including the published Beibei strain are more closely related to two other species of booklice, L. paeta and L. sculptilis, than to the sexual strains of L. bostrychophila. Our results revealed highly divergent mt genomes in the booklouse, L. bostrychophila, and indicated that L. bostrychophila is a cryptic species.The booklouse, Liposcelis bostrychophila is an important stored pest worldwide.

Changes in Ascending Aorta Wall in Aortic Valve Diseases - Clinico-Pathological Correlation

Changes in ascending aorta wall in aortic valve diseases - clinico-pathological correlation Ascending aorta is an initial portion of the thoracic aorta. Ascending aorta and aortic valve share an intimate anatomical position and influence each other hemodynamically. Surgical specimens from the ascending aorta are mostly removed for aortic aneurysm or dissection, which are the consequences of a wide range of risk factors, diseases, syndromes, or ageing. In most cases, aneurysms are asymptomatic being diagnosed incidentally during imaging for another reason. The dangerous clinical manifestation of aneurysms is called an acute aortic syndrome, including aortic dissection. Surgical replacement of the affected aorta by a prosthesis in either case (aneurysm and dissection) represents the method of choice. If the aortic valve displays a defect, it is possible to replace it as well. In 2015 and 2016, The Society for Cardiovascular Pathology and The Association for the European Cardiovascular Pathology published consensus documents on the aortic wall. The nomenclature and grading schemes are unified and specified in detail. The incidence and grading of particular lesions significantly differed in various studies until the consensus documents were published. Diseases of the aortic wall include medial...Změny stěny ascendentní aorty u vad aortální chlopně - klinicko-patologická korelace Ascendentní (vzestupná) aorta tvoří počáteční úsek hrudní aorty. Spolu s aortální chlopní sdílí embryonální vývoj a blízkou anatomickou polohu, čímž se vzájemně hemodynamicky ovlivňují. Nejčastějším důvodem chirurgické resekce ascendentní aorty je aneurysma nebo disekce. Aneurysma zprvu ve většině případů nezpůsobuje závažné klinické příznaky a diagnostikováno je obvykle při zobrazovacím vyšetření z jiného důvodu. Nebezpečí aneurysmatu spočívá ve vzniku tzv. akutního aortálního syndromu, kam se mimo jiné řadí disekce aorty. Metodou první volby u léčby pokročilého aneurysmatu a u aortální disekce ascendentní aorty je její chirurgická náhrada protézou. V případě doprovodné vady aortální chlopně je možné spolu s aortou nahradit i aortální chlopeň. Až do let 2015 a 2016, kdy Asociace pro evropskou kardiovaskulární patologii a společnost kardiovaskulární patologie vydaly dva doporučené postupy pro hodnocení histopatologických nálezů v aortálních biopsiích, byla nomenklatura a hodnocení tíže histopatologických změn značně nejednotná a incidence jednotlivých nálezů v jednotlivých studiích značně rozdílná. Dle těchto nových doporučených postupů mezi onemocnění aortální stěny patří jednak onemocnění degenerativní, jednak...The Fingerland Department of PathologyFingerlandův ústav patologieLékařská fakulta v Hradci KrálovéFaculty of Medicine in Hradec Králov

Fumigation methods of wood to control invasive cermabycid beetles from then genus invazním Anoplophora sp.

Longhorn beetles Anoplophora glabripennis and Anoplophora chinensis are quarantine pests of woody plants, which are, among other routes, spread in wooden pallets and packaging. The methodology describes the effective application of EDN(R) (active substance ethanedinitrile) in the treatment of wooden packaging and untreated wood in order to reduce the risk of the introduction of invasive species of wood-destroying pests (Anoplophora spp.) into the Czech Republic. Quarantine fumigation with methyl bromide is banned in the EU, and the alternative method of heat treatment (ISMP 15) is logistically demanding and cannot be performed in containers or under tarpaulin. The specific objective of the methodology is to provide a technical description of the procedure for the effective application (under tarpaulin / in a container) of EDN(R) to control longhorn beetles A. glabripennis and A. chinensis; the methodology is also prepared as a basis for the possible need for a rapid emergency regulation (ÚKZÚZ - CISTA) for the use in the Czech Republic of Anoplophora spp. longhorn beetles. Another goal is to give a brief overview and evaluation of methods and used products for phyto-quarantine wood treatment in comparison with the new procedure. The methodology is based on original experimental data, which was the basis for determining effective doses of EDN; the doses were expressed as the so-called Ctproduct of concentration and time. Ct- EDN products were determined to a large extent on the model species of longhorn beetle Hylotrupes bajulus (so-called adequate / analogous model species), and then validated for both target species of quarantine longhorn beetles A. glabripennis and A. chinensis. The methodology presents technical specifications and the use of application equipment for the application of liquefied EDN from cylinders using nitrogen as a propellant

Methodology of treatment of infested wood by spruce bark beetle (Ips typographus) using EDN(R) fumigation preparation

The methodology describes the effective application of EDN(R) in the treatment of unprocessed wooden logs on heaps in forest. This methodology provides the technical and biological information regarding effective application of EDN(R) with the active substance ethanedinitrile in the treatment of harvested spruce logs in order to reduce the risk of spreading European spruce bark beetle (Ips typographus). The methodology describes technical specifications and the use of special application equipment for the application of the liquefied EDN from cylinders using nitrogen as an inert drive to treat harvested coniferous wood. The methodology is based on original experimental data. The general goal of the methodology was to help mitigate the current bark beetle calamity in the Czech Republic. The specific objectives of the methodology were to provide (i) objective and original information for the purposes of professional pest control staff and supervisory authorities (especially CISTA) on the method and procedure for treating wood using the EDN(R) product; ii) methodological documents necessary for repeated rapid preparation of the CISTA regulation for the use of EDN for the treatment of landfills under tarpaulin; and (iii) to provide a brief overview of published scientific information and an evaluation of the methods and preparations used for phyto-quarantine treatment of wood against European spruce bark beetle (Ips typographus) in comparison with the new procedure described in this methodology (i.e. EDN-fumigation of piles of spruce-logs under a plastic sheet)
