  • Dothistroma Needle Blight of Pines by the Bartlett Lab Staff Directed by Kelby Fite, Phd
    RESEARCH LABORATORY TECHNICAL REPORT Dothistroma Needle Blight of Pines By the Bartlett Lab Staff Directed by Kelby Fite, PhD Dothistroma Needle Blight (DNB), also known as Red Band Needle Blight, is a serious disease of pines. It is caused by the fungus Mycosphaerella pini. Dothistroma septosporum and is the asexual stage of the fungus, which is commonly found on diseased needles. DNB has been reported from over 60 countries infecting over 80 different species of pine and several other non-pine species. Austrian, Monterey, and Ponderosa pine are the pine species most susceptible to this disease. DNB infects needles of all ages, causing a reduction in photosynthetic capacity and premature mortality. Symptoms these conditions, the spores landing on the new needles germinate and penetrate the tissue through Symptoms of the disease first appear as light green stomata in only a few days. Fruiting bodies will lesions on needles. Lesions eventually turn tan to eventually erupt through the needle surface and reddish brown as the disease develops. It is within these red bands that the small, black, spore-containing Figure 2: Symptoms on canopy fruiting bodies tend to be found with symptoms most apparent in June and July (Figure 1). A distinct transition line forms between the necrotic lesion and healthy green tissue. Needle tips may die back while the bases remain green in severe cases. Premature needle drop occurs, leading to gradual thinning of the canopy. Symptoms are most severe in portions of the canopy located within 6 to 10 feet of the ground (Figure 2). Figure 1: Fruiting bodies on needles Disease Cycle The infected needles on the tree and the fallen needles on the ground serve as sources of inoculum.

Secondary metabolism of the forest pathogen Dothistroma septosporum A thesis presented in the partial fulfilment of the requirements for the degree of Doctor of Philosophy (PhD) in Genetics at Massey University, Manawatu, New Zealand Ibrahim Kutay Ozturk 2016 ABSTRACT Dothistroma septosporum is a fungus causing the disease Dothistroma needle blight (DNB) on more than 80 pine species in 76 countries, and causes serious economic losses. A secondary metabolite (SM) dothistromin, produced by D. septosporum, is a virulence factor required for full disease expression but is not needed for the initial formation of disease lesions. Unlike the majority of fungal SMs whose biosynthetic enzyme genes are arranged in a gene cluster, dothistromin genes are dispersed in a fragmented arrangement. Therefore, it was of interest whether D. septosporum has other SMs that are required in the disease process, as well as having SM genes that are clustered as in other fungi. Genome sequencing of D. septosporum revealed that D. septosporum has 11 SM core genes, which is fewer than in closely related species. In this project, gene cluster analyses around the SM core genes were done to assess if there are intact or other fragmented gene clusters. In addition, one of the core SM genes, DsNps3, that was highly expressed at an early stage of plant infection, was knocked out and the phenotype of this mutant was analysed.

Dothistroma Needle Blight on High Altitude Pine Forests in Montenegro. Baltic Forestry 23(1): 294-302. Abstract Dothistroma needle blight (DNB) is one of the most serious and widespread needle diseases of pines. Its current distribu- tion was investigated in high altitude native and planted pine forests in Montenegro. The suitability for the disease under different climatic conditions is discussed. Using molecular methods, polymerase chain reaction (PCR) with species specific primers, Dothistroma septosporum (Dorog) M. Morelet was detected from needles of Pinus nigra Arn., Pinus nigra ‘Dalmatica’ (Visiani) Franco, Pinus sylvestris L., Pinus mugo Turra, Pinus heldreichii H. Christ, Pinus peuce Griseb. and Picea abies Karst. in differ- ent parts of Montenegro, at altitudes between 800 and 2150 m. Dothistroma pini Hulbary was detected from P. sylvestris, P. nigra and P. mugo from restricted area in Northwestern part of Montenegro at altitudes between 800 and 1850 m. This is the first report of DNB on P. mugo and P. abies in Montenegro, and the first time that D. septosporum was detected from P.nigra ‘Dal- matica’.

    Heritage lecture / Allocution du patrimoine Staffan Lindgren Trips, traps, triumphs and tribulations: A journey from childhood dreams to a dream-career in entomology Modified from the Heritage Lecture presented at the Joint Annual Meeting of the Entomological Societies of Canada and British Columbia, Vancouver, 2 November 2010 hen first asked to deliver the 2010 Heritage Lecture (Fig. 1), WI immediately started thinking about what the word “heritage” actually means. I turned to the authoritative Wikipe- dia for the answer, and found the following (http://en.wikipedia.org/wiki/Heritage): “Heritage” refers to something inherited from one’s ancestors. It has several differ- ent senses, including: Natural heritage, a group’s inheritance of fauna and flora, geology, landscape and landforms, and other natural resources Dezene Huber Cultural heritage, the legacy of physi- cal artifacts and intangible attributes of a Fig. 1. Staffan presenting the Heritage Lecture. group or society: man-made heritage In entomology, our heritage combines these two, but it is really cultural heritage that makes humans what they are, in that we can pass accumulated knowledge down from generation to generation. Knowledge isn’t acquired by osmosis, however. All of us have had people in our lives who have guided and inspired us, our mentors. Returning to the web, I found the following: Mentor - A wise and trusted counselor or teacher Mentorship - “… informal transmission of knowledge… relevant to work, career, or profes- sional development Mentoring entails informal communication… during a sustained period of time, between … the mentor and …the protégé.” (Modified from Bozeman and Feeney 2007) This paper is not meant to focus on me, but rather to recognize the importance of heritage and mentorship.

  • Red Band Needle Blight of Conifers in Britain
    Research Note Red band needle blight of conifers in Britain Anna Brown and Joan Webber June 2008 Red band needle blight is an economically important disease affecting a number of coniferous trees, in particular pines. The disease has a world-wide distribution but until recently it was mainly of concern in the southern hemisphere. In much of the world, including Britain, it is caused by the fungus Dothistroma septosporum . Red band needle blight causes premature needle defoliation which results in the loss of timber yield and, in severe cases, tree mortality. Since the late 1990s the incidence of the disease has increased dramatically in Britain, particularly on Corsican pine ( Pinus nigra ssp. laricio ), and due to the extent and severity of the disease on this species, there is now a five-year planting moratorium of it on the Forestry Commission estate. More recently there have been reports of the disease causing damage to lodgepole pine in Scotland and it has also been reported on Scots pine – although it rarely appears to be causing significant damage to this species. Reasons for the increase in disease incidence are unclear but could be due to increased rainfall in spring and summer coupled with a trend towards warmer springs, optimising conditions for spore dispersal and infection. Such conditions may become more prevalent in Britain over the next 20 years if current trends in climate change continue. In Britain disease management is currently focused on silvicultural measures to reduce inoculum loads and the use of alternative, less susceptible species in future rotations.

  • Multigene Phylogenies Reveal That Red Band Needle Blight of Pinus Is Caused by Two Distinct Species of Dothistroma, D
    STUDIES IN MYCOLOGY 50: 551–565. 2004. Multigene phylogenies reveal that red band needle blight of Pinus is caused by two distinct species of Dothistroma, D. septosporum and D. pini Irene Barnes1*, Pedro W. Crous2, Brenda D. Wingfield1 and Michael J. Wingfield1 1Department of Genetics, Forestry and Agricultural Biotechnology Institute (FABI), University of Pretoria, Pretoria, South Africa, 0002; 2 Centraalbureau voor Schimmelcultures (CBS), Fungal Biodiversity Centre, P.O. Box 85167, 3508 AD Utrecht, The Netherlands *Correspondence: I. Barnes, [email protected] Abstract: The red band needle blight fungus, Dothistroma septosporum is a widely distributed pathogen of many pine species. Three morphological varieties of this pathogen have been described based on differences in conidial length. However, contro- versy exists as to whether spore size represents an adequate characteristic to distinguish between forms of D. septosporum. The aim of this investigation was to consider the phylogenetic relationships between D. septosporum isolates from different coun- tries. An additional objective was to determine whether comparisons of DNA sequence data support the morphological varie- ties recognized for this species. DNA from portions of the nuclear ribosomal internal transcribed spacer (ITS), -tubulin and elongation factor 1- genes were sequenced and analysed for isolates from 13 different countries representing five continents. Results show that isolates of the pathogen encompass two divergent lineages representing distinct phylogenetic species. One phylogenetic species (Lineage I) is found worldwide, while the other (Lineage II), is restricted to the North-Central U.S.A. The names D. pini and D. septosporum are available for these species. The former name should apply to the phylogenetic species currently known only from the United States.

  • A Stand Establishment Decision Aid for Warren Root Collar Weevil
    Extension Note BC Journal of Ecosystems and Management British Columbia’s Northern Interior Forests Warren Root Collar Weevil Stand Establishment Decision Aid Larry McCulloch1, Brian Aukema2, Ken White3, and Matthew Klingenberg4 Introduction Warren root collar weevil (Hylobius warreni) is a commonly occurring insect found in most of British Columbia and as far north as the Northwest Territories. This weevil affects many tree species and is found in forest stands of any age, although its impact as a disturbance agent is most important in lodgepole pine stands. Engelmann and white spruce are also common hosts, but incidence levels have not been high enough with these species to cause reforestation issues. Incidence levels in lodgepole pine stands commonly exceed 30%, although mortality levels are generally far less and occur in younger stands (5–20 years of age). Recent research suggests that a link exists between stands affected by mountain pine beetle (MPB) and root collar weevil. In one study, the incidence of weevil-attacked trees was elevated in young plantations adjacent to mature stands that had sustained high levels of MPB-caused mortality. An understanding of the weevil’s biology and the identification of high-hazard stand conditions for both insect species are essential to successfully avoid regeneration issues. Most treatments involve mitigation measures applied during stand establishment. The Stand Establishment Decision Aid (SEDA) format has been used to extend information on a variety of vegetation and forest health concerns in British Columbia. The two-page SEDA presented in this extension note was developed to summarize information that northern forest managers will need to manage the impacts of the Warren root collar weevil.
