  • New Records of Some Pests of the Coconut Inflorescence and Developing Fruit and Their Natural Enemies in Sri Lanka
    COCOS, (1987) 5, 39—42 Printed in Sri Lanka New Records of some Pests of the Coconut Inflorescence and Developing Fruit and Their Natural Enemies in Sri Lanka L. C. P. FERNANDO and P. KANAGARATNAM Coconut Research Institute, Lunuwila, Sri Lanka. ABSTRACT A survey was carried out at Bandirippuwa Estate, Kirimetiyana Estate and at Isolated Seed Garden, Rajakadaluwa for the pests of coconut inflorescence and developing fruits. The mite, Dolichotetranychus sp. (Tenuipalpidae) which lives beneath the perianth and feeds on the epicarp, causes considerable damage to the developing fruit. Bi-monthly observations on the intensity of infestation of nuts among different forms of coconut indicated a significant difference among forms in their susceptibility to mite damage. Pseudococcus cocotis (Maskell) (Pseudococcidae), Pseudococcus citriculus Green (Pseudococcidae) and Planococcus lilacinus (Cockereli) (Pseudococcidae), when feeding in large numbers on the peduncle, cause button nut shedding and drying up of the inflo­ rescence. The parasitoids and predators of these mealybugs recorded for the first time in Sri Lanka are Promuscidea unfasciativentris Girault (Aphelinidae) Platygaster sp. (Platygastridae), Anagyrus sp. nr. pseudococci (Girault) (Encyrtidae) Coccodiplosis sp. (Cecidomyiidae), Cryptogonus bryanti Kapur (Coccinellidae) and Pseudoscymnus sp. (Coccinellidae). Several species of scale insects namely, Coccus hesperidum (Linnaeus) (Coccidae) Aulacaspis sp. (Diaspididae), Pseudaulacaspis cockerelli (Cooley) (Diaspididae), Aoni- diella orientalis (Newstead) (Diaspididae), and Pinnaspis strachani (Cooley) (Diaspididae) are recorded as minor pests of the developing fruits of coconut. Coccophagus silvestrii Compere (Aphelinidae), Scymnus sp. (Coccinellidae), Pseudoscymnus sp. (Coccinellidae) Telsimia ceylonica (Weise) (Coccinellidae), Cryptogonus bryanti Kapur (Coccinellidae) and Cybocephalus sp. (Nitidulidae) are recorded as their parasitoids and predators. These natural enemies are probably responsible for the control of these pests in the field.

  • Fung Yuen SSSI & Butterfly Reserve Moth Survey 2009
    Fung Yuen SSSI & Butterfly Reserve Moth Survey 2009 Fauna Conservation Department Kadoorie Farm & Botanic Garden 29 June 2010 Kadoorie Farm and Botanic Garden Publication Series: No 6 Fung Yuen SSSI & Butterfly Reserve moth survey 2009 Fung Yuen SSSI & Butterfly Reserve Moth Survey 2009 Executive Summary The objective of this survey was to generate a moth species list for the Butterfly Reserve and Site of Special Scientific Interest [SSSI] at Fung Yuen, Tai Po, Hong Kong. The survey came about following a request from Tai Po Environmental Association. Recording, using ultraviolet light sources and live traps in four sub-sites, took place on the evenings of 24 April and 16 October 2009. In total, 825 moths representing 352 species were recorded. Of the species recorded, 3 meet IUCN Red List criteria for threatened species in one of the three main categories “Critically Endangered” (one species), “Endangered” (one species) and “Vulnerable” (one species” and a further 13 species meet “Near Threatened” criteria. Twelve of the species recorded are currently only known from Hong Kong, all are within one of the four IUCN threatened or near threatened categories listed. Seven species are recorded from Hong Kong for the first time. The moth assemblages recorded are typical of human disturbed forest, feng shui woods and orchards, with a relatively low Geometridae component, and includes a small number of species normally associated with agriculture and open habitats that were found in the SSSI site. Comparisons showed that each sub-site had a substantially different assemblage of species, thus the site as a whole should retain the mosaic of micro-habitats in order to maintain the high moth species richness observed.

  • Seiridium Cardinale on Juniperus Species in Greece
    For. Path. 37 (2007) 338–347 doi: 10.1111/j.1439-0329.2007.00510.x Ó 2007 The Authors Journal compilation Ó 2007 Blackwell Verlag, Berlin Seiridium cardinale on Juniperus species in Greece By P. Tsopelas1, I. Barnes2, M. J. Wingfield2 and S. Xenopoulos1 1NAGREF-Institute of Mediterranean Forest Ecosystems, Terma Alkmanos, 115 28 Athens, Greece. E-mail: [email protected]; 2Forestry and Agricultural Biotechnology Institute (FABI), Department of Genetics, University of Pretoria, Pretoria, South Africa Summary Seiridium cardinale, the cause of cypress canker disease, was found on Juniperus foetidissima, J. excelsa, J. oxycedrus and J. phoenicea, in a number of natural juniper woodlands in Greece. The presence of infections was sporadic in most cases, with a limited number of plants affected by the pathogen. At one locality in the Prespes Lakes region of northern Greece, however, the incidence of infection was very high, especially on J. foetidissima and J. excelsa. The identity of S. cardinale was confirmed using morphological characters and comparisons of DNA sequences for the b-tubulin gene region. The pathogenicity of S. cardinale isolates from Juniperus and Cupressus was verified in cross-inoculation trials on both potted and field grown plants. 1 Introduction The fungus Seiridium cardinale (Wag.) Sutton & Gibson causes a serious canker disease on cypress trees and other members of the Cupressaceae. It was originally reported in California on Monterey cypress (Cupressus macrocarpa Hartweg.; Wagener 1928) and it is believed that the disease was spread from North America to many other areas of the world. The fungus has been found in South America, South Africa, Europe, Asia, Australia and New Zealand (Grasso and Ponchet 1979; Graniti 1998).

They display remarkable social organization that has enabled them to be ubiquitous throughout the world. They make up approximately 10% of the world’s animal biomass. Ants provide ecosystem services in agrosystems by playing a major role in plant pollination, soil bioturbation, bioindication, and the regulation of crop-damaging insects. Over recent decades, there have been numerous studies in ant ecology and the focus on tree cropping systems has given added importance to ant ecology knowledge.

    Bol. San. Veg. Plagas, 17: 423-439, 1991 Notas sobre el cáncer del ciprés (Seiridium cardinale (Wag.) Sutt. et Gibs.) I. GIMÉNEZ VERDÚ Estre trabajo recoge una serie de notas acerca de las características sintomatoló- gicas, etiológicas, biológicas, epidemiológicas, terapéuticas y de otros aspectos de in- terés sobre el cáncer del ciprés, producido por el Deuteromiceto Melanconial Seiri- dium cardinale (Wag.) Sutt. et Gibs., sin. de Coryneum cardinale Wag. Del mismo modo son incluidas diversas indicaciones en torno al origen e introduc- ción de la planta huésped y de otras Cupresáceas en nuestro país, viniendo conside- rado entre otros datos su uso, difusión y diversa sensibilidad al patógeno. En control químico se hace referencia a las principales líneas, destacando el uso de apositos sobre heridas como Santar-SM o Vinavil y de tratamientos con benomylo, carbendazima, metil-tiofanato y sus asociaciones con captafol o diclofluanida, aconse- jando la importancia de proteger viveros. En cuanto a la mejora genética, en la que se piensa, recae fundamentalmente la posibilidad de una solución más eficaz que la procurada por los biocidas en el control de la enfermedad, se tiene en cuenta la selección de cultivares, creación de variedades multiclonales y a partir de éstas la creación de viveros, consecución de una adaptación pedoclimática estable en los ejemplares seleccionados y previsión de una posible apa- rición de patotipos capaces de rebasar la resistencia. Finalmente se indica que por el momento no han sido identificados en las mues- tras recogidas Lepteutypa cupressi (Natras et al.) Swart 1973, así como tampoco Sei- ridium unicorne (Cooke et Eli.) Sutton 1975, concluyéndose en haber sido observado como transmisor principal de la enfermedad al escolítido Phloesinus aubei (Perr.).

  • Weed Biocontrol: Extended Abstracts from the 1997 Interagency Noxious-Weed Symposium
    Weed Biocontrol: Extended Abstracts from the 1997 Interagency Noxious-Weed Symposium Dennis Isaacson Martha H. Brookes Technical Coordinators U.S. Department of Agriculture Forest Service Forest Health Technology Enterprise Team Morgantown, WV and Oregon Department of Agriculture Salem, OR June 1999 ACKNOWLEDGMENTS Many of the tasks of organizing a symposium such as this — and there are many — are not obvious, and, if they are handled well, the effort that goes into them can easily be overlooked. Sherry Kudna of the Oregon Department of Agriculture Weed Control staff managed most of the arrangements and took care of many, many details, which helped the symposium run smoothly. We truly appreciate her many contributions. We also acknowledge the contributions of the presenters. They not only organized their own presentations and manuscripts, but also assisted with reviewing drafts of each other’s papers in the proceedings. Several of the presenters also covered their own expenses. Such dedication speaks well of their commitment to improving the practice of weed biocontrol. Both the Oregon State Office of the Bureau of Land Management and the USDA Forest Service made major contributions to supporting the symposium. Although several individuals from both organizations provided assistance, we especially note the encouragement and advice of Bob Bolton, Oregon Bureau of Land Management Weed Control Coordinator, and the willingness to help and financial support for publishing this document from Richard C. Reardon, Biocontrol/Biopesticides Program Manager, USDA Forest Service's Forest Health Technology Enterprise Team, Morgantown, WV. We thank Tinathan Coger for layout and design and Patricia Dougherty for printing advice and coordination of the manuscript We also thank Barbra Mullin, Montana State Department of Agriculture, who delivered the keynote address; Tami Lowry, Pacific Northwest Research Station, Corvallis, who helped format the document; and Eric Coombs, who provided the photographs of weeds and agents that convey the concepts of weed biocontrol.

  • (Sporocadaceae): an Important Genus of Plant Pathogenic Fungi
    Persoonia 40, 2018: 96–118 ISSN (Online) 1878-9080 www.ingentaconnect.com/content/nhn/pimj RESEARCH ARTICLE https://doi.org/10.3767/persoonia.2018.40.04 Seiridium (Sporocadaceae): an important genus of plant pathogenic fungi G. Bonthond1, M. Sandoval-Denis1,2, J.Z. Groenewald1, P.W. Crous1,3,4 Key words Abstract The genus Seiridium includes multiple plant pathogenic fungi well-known as causal organisms of cankers on Cupressaceae. Taxonomically, the status of several species has been a topic of debate, as the phylogeny of the appendage-bearing conidia genus remains unresolved and authentic ex-type cultures are mostly absent. In the present study, a large collec- canker pathogen tion of Seiridium cultures and specimens from the CBS and IMI collections was investigated morphologically and Cupressus phylogenetically to resolve the taxonomy of the genus. These investigations included the type material of the most pestalotioid fungi important Cupressaceae pathogens, Seiridium cardinale, S. cupressi and S. unicorne. We constructed a phylogeny systematics of Seiridium based on four loci, namely the ITS rDNA region, and partial translation elongation factor 1-alpha (TEF), β-tubulin (TUB) and RNA polymerase II core subunit (RPB2). Based on these results we were able to confirm that S. unicorne and S. cupressi represent different species. In addition, five new Seiridium species were described, S. cupressi was lectotypified and epitypes were selected for S. cupressi and S. eucalypti.
