The purpose of the pest categorisation is to determine what quarantine pests are potentially associated with the washed ware potato pathway. Washed ware potatoes from interstate are currently permitted entry into Western Australia under strict quarantine conditions for specific pests and diseases. This policy has been in place for many years and is being reviewed to ensure it provides an appropriate level of protection for the state. The policy review is being undertaken via a pest risk analysis (PRA) process. A PRA is one mechanism by which DAFWA’s Plant Biosecurity Policy Group determines the biosecurity risks associated with commodities imported from other Australian states and territories, and provides scientific justification for any recommended phytosanitary measures. Any recommended phytosanitary measures are required to be compliant with international and national agreements. The draft pest categorisation (this document) identifies invertebrate and pathogen pests that are: associated with the washed ware potato pathway, absent from Western Australia, have the potential to establish in Western Australia, and be of economic concern should they establish in Western Australia. This report has assessed 430 candidate organisms potentially associated with commercial and non-commercial potato production in Australia (Table 1). Of these candidate organisms, 6 invertebrates and 31 pathogens (Table 2) were identified as pests of quarantine concern associated with the washed ware potato pathway that satisfy the International Plant Protection Convention (IPPC) definition of a quarantine pest: ‘A pest of potential economic importance to the area endangered thereby and not yet present there, or present but not widely distributed and being officially controlled’ (ISPM 5 2016). At the conclusion of the consultation period for this draft pest categorisation, DAFWA will consider stakeholder submissions and incorporate relevant information into the draft policy review. The quarantine pests identified in the pest categorisation will undergo further assessment in the draft policy review to: determine the unrestricted risk of entry, establishment and spread of the pests in Western Australia, and determine the extent where necessary of any phytosanitary measures required to provide an appropriate level of protection for Western Australia. 1 Plant Biosecurity Policy | Washed Ware Potatoes Policy Review - Draft Pest Categorisation Table 1: Pest categorisation summary1 Organism group Associated with Absent from Potential Potential to Potential for Quarantine pest Australian potato Western Australia presence on the establish economic species production or of regional washed ware consequences concern potato pathway Mites 7 2 1 1 1 1 Insects 158 35 9 9 5 5 Total invertebrates 165 37 10 10 6 6 No data in this row Bacteria 25 6 5 5 3 3 Phytoplasmas 5 1 0 0 0 0 Fungi 167 61 23 22 16 16 Nematodes 47 24 6 6 6 6 Protozoa 2 0 0 0 0 0 Viruses & Viroids 19 6 6 6 6 6 Total pathogens 265 98 40 39 31 31 No data in this row Total organisms 430 135 50 49 37 37 1Numbers include organisms with incomplete categorisation. 2 Plant Biosecurity Policy | Washed Ware Potatoes Policy Review - Draft Pest Categorisation Table 2 Quarantine pests associated with imported washed ware potatoes Scientific name Common name Invertebrate Cheiroplatys latipes (Guérin-Méneville, 1831) potato scarab Hapatesus (Hapatesus) hirtus Candèze, 1863 potato wireworm Rhizoglyphus robini Claparède, 1868 bulb mite Rhopaea magnicornis Blackburn, 1888 rhopaea canegrub Sericesthis geminata Boisduval, 1835 pruinose scarab Pathogen Alternaria protenta E.G.

  • Field Fungal Diversity in Freshly Harvested Japonica Rice
    1 Field fungal diversity in freshly harvested japonica rice 2 3 4 5 ABSTRACT 6 Rice is a major food crop in China and Japonica rice production in Heilongjiang 7 Province ranks No.1 in total annual rice production in the country. Rice is prone to 8 invasion by fungi and mycotoxins produced by the fungi are proven to be serious 9 threats to human health. The objective of the present study was to investigate fungal 10 diversity of freshly harvested rice in the four main cultivation regions of Heilongjiang 11 Province in order to find the abundance difference of dominant fungi among the four 12 regions. Through high throughput sequencing we detected Ascomycota accounts for 13 absolute dominant phylum; Dothideomycetes, Sordariomycetes, Tremellomycetes, 14 Microbotryomycetes, and Eurotiomycetes were dominant classes; Capnodiales, 15 Hypocreales, and Pleosporales were the main orders; Cladosporiaceae, Pleosporaceae, 16 Nectriaceae, Clavicipitaceae, Tremellaceae, Phaeosphaeriaceae, 17 Trimorphomycetaceae, Sporidiobolaceae, Bionectriaceae, and Trichocomaceae were 18 major family; Cladosporium, Epicoccum, Fusarium, and Alternaria were the most 19 abundant phylotypes at genus level; Epicoccum_nigrum, Gibberella_zeae, and 20 Fusarium_proliferatum were the dominant fungal species. Great fungal diversity was 21 observed in the rice samples harvested in the four major Japonica rice-growing regions 22 in Heilongjiang province. However, no significant difference in diversity was observed 23 among the four regions, likely due to the relatively close geographical proximity 24 leading to very similar climatic conditions. Since some of the fungal species produce 25 mycotoxins, it is necessary to take precautions to ensure the rice is stored under safe 26 conditions to prevent the production of mycotoxins.

Abstract — Three new genera, Anaplusia gen. n., Extremoplusia gen. n. and Scriptoplusia gen. n. and one new species, Scriptoplusia noona sp. n. are described and an annotated list of 50 species from N America, Africa and the Oriental Region is given. With 26 figures and 1 photoplate. In 1986Ihadtthe opportunity to study the Palaeotropical, Nearctic and Indo-Australian Plusiinae material of the Zoological Museum of Copenhagen. During the course of this work I could study in details some species which had not been relagated to any described genera. These studies, based on the external and genitalic morphology including the characteristics of the vesica, have shown the necessity to erect three new genera for these taxa. — The whole material contains specimens of 50 species, one of them is new for science and there are several previously unknown distribution records of the species. I would like to express my thanks to Dr. Ole Karsholt (Zool. Mus., Copenhagen) for his exten­ sive help in this work and also to Dr. L. Gozmány (Budapest) for his useful advice. 1. DESCRIPriON OF THE NEW TAXA It is an interesting fact that there are some species, distributed over the Eastern-South­ eastern border of the Palaearctic Region to Indonesia, Australia and New Guinea, which appear to be remote from any well-known genera of the Eastern Tropical Plusiinae.

Histological studies revealed that the Erythroneura species induced white stipples on the leaves and that these leafhoppers produced thin salivary sheaths in grapevine leaf tissues. The DC-EPG system allowed the characterization of five waveforms associated with stylet penetration and feeding in leaf tissues. These waveforms were characteristic of feeding phases corre- sponding to epidermis penetration pathway, salivation, and ingestion. We calculated 28 parameters (e.g., number of probes, duration of phases, and time spent in the various tissues) to describe and compare the feeding behavior of the Erythroneura species.

  • Virus Infection Mediates the Effects of Elevated CO2 on Plants and Vectors Received: 15 December 2015 Piotr Trębicki1, Rebecca K
    www.nature.com/scientificreports OPEN Virus infection mediates the effects of elevated CO2 on plants and vectors Received: 15 December 2015 Piotr Trębicki1, Rebecca K. Vandegeer2, Nilsa A. Bosque-Pérez3, Kevin S. Powell4, Accepted: 19 February 2016 Beatriz Dader1,5, Angela J. Freeman2, Alan L. Yen2, Glenn J. Fitzgerald6 & Jo E. Luck7 Published: 04 March 2016 Atmospheric carbon dioxide (CO2) concentration has increased significantly and is projected to double by 2100. To increase current food production levels, understanding how pests and diseases respond to future climate driven by increasing CO2 is imperative. We investigated the effects of elevated CO2 (eCO2) on the interactions among wheat (cv. Yitpi), Barley yellow dwarf virus and an important pest and virus vector, the bird cherry-oat aphid (Rhopalosiphum padi), by examining aphid life history, feeding behavior and plant physiology and biochemistry. Our results showed for the first time that virus infection can mediate effects of eCO2 on plants and pathogen vectors. Changes in plant N concentration influenced aphid life history and behavior, and N concentration was affected by virus infection under eCO2. We observed a reduction in aphid population size and increased feeding damage on noninfected plants under eCO2 but no changes to population and feeding on virus-infected plants irrespective of CO2 treatment. We expect potentially lower future aphid populations on noninfected plants but no change or increased aphid populations on virus-infected plants therefore subsequent virus spread. Our findings underscore the complexity of interactions between plants, insects and viruses under future climate with implications for plant disease epidemiology and crop production. Climate change is of global concern due to its predicted impacts on the environment and agriculture.

  • The Phylogeny of Plant and Animal Pathogens in the Ascomycota
    Physiological and Molecular Plant Pathology (2001) 59, 165±187 doi:10.1006/pmpp.2001.0355, available online at http://www.idealibrary.com on MINI-REVIEW The phylogeny of plant and animal pathogens in the Ascomycota MARY L. BERBEE* Department of Botany, University of British Columbia, 6270 University Blvd, Vancouver, BC V6T 1Z4, Canada (Accepted for publication August 2001) What makes a fungus pathogenic? In this review, phylogenetic inference is used to speculate on the evolution of plant and animal pathogens in the fungal Phylum Ascomycota. A phylogeny is presented using 297 18S ribosomal DNA sequences from GenBank and it is shown that most known plant pathogens are concentrated in four classes in the Ascomycota. Animal pathogens are also concentrated, but in two ascomycete classes that contain few, if any, plant pathogens. Rather than appearing as a constant character of a class, the ability to cause disease in plants and animals was gained and lost repeatedly. The genes that code for some traits involved in pathogenicity or virulence have been cloned and characterized, and so the evolutionary relationships of a few of the genes for enzymes and toxins known to play roles in diseases were explored. In general, these genes are too narrowly distributed and too recent in origin to explain the broad patterns of origin of pathogens. Co-evolution could potentially be part of an explanation for phylogenetic patterns of pathogenesis. Robust phylogenies not only of the fungi, but also of host plants and animals are becoming available, allowing for critical analysis of the nature of co-evolutionary warfare. Host animals, particularly human hosts have had little obvious eect on fungal evolution and most cases of fungal disease in humans appear to represent an evolutionary dead end for the fungus.
