Thesis Characterizing the Pine Wilt THESIS CHARACTERIZING THE PINE WILT DISEASE PATHOSYSTEM IN THE FRONT RANGE REGION OF COLORADO Submitted by David Atkins Department of Forest & Rangeland Stewardship In partial fulfillment of the requirements For the Degree of Master of Science Colorado State University Fort Collins, Colorado Spring 2020 Master’s Committee Advisor: Seth Davis Co-advisor: Jane Stewart Diana Wall Wade Tinkham Copyright by David H. Atkins 2020 All Rights Reserved ABSTRACT CHARACTERIZING THE PINE WILT DISEASE PATHOSYSTEM IN THE FRONT RANGE OF COLORADO Pine wilt disease, caused by the pinewood nematode (Bursaphelenchus xylophilus; PWN), is one of the most damaging invasive species in Asia. Tree mortality associated with PWN has recently been reported in Colorado and surrounding states. There remains little documentation on PWN incidence in native pine species or the biology of potential vectors in the Rocky Mountain region. Here we regionally surveyed for PWN in host trees and two putative insect vectors (Monochamus clamator & M. scutellatus) for two years to develop vector flight phenology models and test the hypothesis that disturbance factors predict vector abundance across the landscape. Flight phenology was similar between vectors: flight initiated in mid-July and continued into October for both species. PWN was distributed throughout the Front Range at rates lower than those reported in the putative native range (Host: 3.6%; Vector 4.2%). Infection rate in hosts varied among sites (0-89%), and four ‘epicenters’ of vector infectivity were identified. We also report the first incidence of PWN-M. clamator association in the U.S. The four identified epicenter sites varied in the timing of anomalous infection frequency, and flight phenology of infective vectors differed between epicenter and peripheral sites. Monochamus populations were found primarily in natural forest areas and seasonally migrate in ii small numbers to urban areas. Landscape factors such as proximity to burned area were positively correlated with Monochamus abundance. Synthesis and applications: Our study describes PWN infection frequency to be greater than that expected of a newly introduced pathogen, but lesser than the eastern United States and Canada where PWN is known to be established. Our findings provide tools that can predict exposure windows of disease exposure, which were observed to be highest in the early season in Colorado. We also describe the threat that populations of PWN in wildland forests pose to urban landscapes, and how this risk varies seasonally. These findings collectively serve characterize PWN distribution in the native ecosystem and provide tools that can be used by decision-makers and managers to proactively manage the spread of pine wilt disease. iii ACKNOWLEDGEMENTS Thank you to those who served as techs and helped out with your time to complete this project, namely Abbi, Ben, Frank, and Lillian. Thank you to my committee members Drs. Diana Wall and Wade Tinkham for your encouragement and helpful feedback as this project progressed.

The nematode reproduces rapidly after introduction into a host tree causing disease symptoms that can appear in 2-3 weeks. Initial symptoms include needle chlorosis and wilting, decreased rate of transpiration, and reduced oleoresin flow which progress rapidly to hydraulic failure and mortality in as little as two months for extremely susceptible hosts. Pine wilt disease system consists of three key trophic levels; the PWN, insect vectors (primarily Cerambycid beetles), and the fungi upon which the nematodes feed. Blue- and black-stain Ophiostomatoid fungi are commonly associated with PWN-killed pines. These fungi are also one of the best naturally occurring substrates for PWN-growth compared to other co-occurring fungi (Kobayahsi, Sasaki, & Mamiya 1974, 1975; Sriwati et al. 2007). The fungi serve as a food source for the nematode after the resources of the host tree are exhausted post-mortality (Fukushige 1991). PWN has an obligate vector relationship with long-horned beetles (Coleoptera; Cerambycidae), specifically the pine sawyer beetles of the genus Monochamus. Monochamus spp. are cosmopolitan and sympatric with host pines throughout the northern hemisphere. These beetles are typically secondary pests in their native range, however their relationship with PWN has greatly increased interest into their biology. Here, I review the literature regarding the PWN pathosystem and disease ecology along with the resulting impacts of PWN in its introduced and native ranges and address knowledge gaps that have become apparent with emphasis on recent work that has been done here in the Front Range Region of Colorado. 1.2 Pine wilt in Asia and Europe Beginning

    Saproxylic beetles in Europe: monitoring, biology and conservation, p. 23–32 GDK 145.76(497.4) Biodiversity of saproxylic beetles of pine forests in Slovenia with emphasis on Monochamus species Maja Jurc1, Srdjan Bojovic2, Roman Pavlin3, Gregor Meterc4, Andreja Repe5, Danijel Borkovič6, Dušan Jurc7 Abstract From 2007 to 2010, we assessed the presence of entomofauna in two ecological regions of Slovenia on three locations: on limestone parent rock in monocultures of Pinus nigra, on flysch in a stand of Pinus halepensis (both in the Sub-mediterranean ecological region) and in a stand of Pinus sylvestris on brown soil (Pre-alpine ecological region). The samples were collected in one-month intervals from May to November using four cross vane funnel traps per location with wet collecting cups and attractants (ethanol+α- pinene, Pheroprax® and Gallowit®). Collected insects from the order Coleoptera belonged to the families Curculionidae (and subfam. Scolytinae), Cerambycidae and Buprestidae. The most important saproxylic groups were Scolytinae as the primary saproxylic beetles at 90.7% (21,820 specimens), containing 21 taxa and 18 species; Cerambycidae at 6.4 % (1534 specimens), 24 taxa, 20 species; Curculionidae at 2.5% (613 specimens), eight species and Buprestidae at 0.4% (90 specimens) and one species. With respect to the number of species identified, the most numerous family was Cerambycidae; the dominant species was Spondylis buprestoides, followed by Rhagium inquisitor, Arhopalus rusticus, Acanthocinus aedilis, Neoclytus acuminatus, Monochamus galloprovincialis, Leiopus nebulosus, Arhopalus ferus, Sticoleptura rubra and Cerambyx scopoli. Collected species of long-horned beetles represent ca. 10% of all known species of Cerambycidae in Slovenia.

  • Inventory and Review of Quantitative Models for Spread of Plant Pests for Use in Pest Risk Assessment for the EU Territory1
    EFSA supporting publication 2015:EN-795 EXTERNAL SCIENTIFIC REPORT Inventory and review of quantitative models for spread of plant pests for use in pest risk assessment for the EU territory1 NERC Centre for Ecology and Hydrology 2 Maclean Building, Benson Lane, Crowmarsh Gifford, Wallingford, OX10 8BB, UK ABSTRACT This report considers the prospects for increasing the use of quantitative models for plant pest spread and dispersal in EFSA Plant Health risk assessments. The agreed major aims were to provide an overview of current modelling approaches and their strengths and weaknesses for risk assessment, and to develop and test a system for risk assessors to select appropriate models for application. First, we conducted an extensive literature review, based on protocols developed for systematic reviews. The review located 468 models for plant pest spread and dispersal and these were entered into a searchable and secure Electronic Model Inventory database. A cluster analysis on how these models were formulated allowed us to identify eight distinct major modelling strategies that were differentiated by the types of pests they were used for and the ways in which they were parameterised and analysed. These strategies varied in their strengths and weaknesses, meaning that no single approach was the most useful for all elements of risk assessment. Therefore we developed a Decision Support Scheme (DSS) to guide model selection. The DSS identifies the most appropriate strategies by weighing up the goals of risk assessment and constraints imposed by lack of data or expertise. Searching and filtering the Electronic Model Inventory then allows the assessor to locate specific models within those strategies that can be applied.

    Colorado Exotic Insect Detection and Identification Fact Sheet Series Asian Longhorned Beetle in Colorado - Identification of Insects and Damage of Similar Appearance Matt Camper and Whitney Cranshaw Figure 1. Asian longhorned beetle larvae. Photo Figure 2. Female Asian longhorned beetle. Photo courtesy of Michael Bohne courtesy of Michael Bohne The Asian longhorned beetle (ALB), Anoplophora glabripennis, is a wood boring beetle of Asian origin that was first detected in Brooklyn in 1996. Two years later a separate infestation was found in the Chicago suburbs. The Asian longhorned beetle has the potential to be very damaging to certain types of hardwood trees, causing tree decline and even death. Many native trees are susceptible to this insect and there are concerns that it could seriously affect natural forest systems as well as shade trees. Intensive efforts to eradicate this insect have been instituted where it was detected. This effort appears to have been very successful in the Chicago infestation and Asian longhorned beetle was officially declared eradicated in 2007. However, infestations in the New York City area have spread more widely so that detections of the insect have occurred in all city boroughs, parts of Long Island, and three New Jersey counties. Areas known to be infested remain fairly small and sustained eradication efforts continue to attempt elimination of the insect in New York and New Jersey. In addition, quarantine efforts prevent movement of wood materials that could be potentially infested from outside the area of known infestation. Introduction of Asian longhorned beetle into Colorado most likely would occur via hardwood packing materials (Figure 3) originating from China-shipped goods.

  • Traps and Attractants for Wood-Boring Insects in Ponderosa Pine Stands in the Black Hills, South Dakota
    FOREST ENTOMOLOGY Traps and Attractants for Wood-Boring Insects in Ponderosa Pine Stands in the Black Hills, South Dakota 1,2,3 2 1 SHERYL L. COSTELLO, JOSE´ F. NEGRO´ N, AND WILLIAM R. JACOBI J. Econ. Entomol. 101(2): 409Ð420 (2008) ABSTRACT Recent large-scale wildÞres have increased populations of wood-boring insects in the Black Hills of South Dakota. Because little is known about possible impacts of wood-boring insects in the Black Hills, land managers are interested in developing monitoring techniques such as ßight trapping with semiochemical baits. Two trap designs and four semiochemical attractants were tested in a recently burned ponderosa pine, Pinus ponderosa Dougl. ex Laws., forest in the Black Hills. ModiÞed panel and funnel traps were tested in combination with the attractants, which included a woodborer standard (ethanol and ␣-pinene), standard plus 3-carene, standard plus ipsenol, and standard plus ipsdienol. We found that funnel traps were equally efÞcient or more efÞcient in capturing wood-boring insects than modiÞed panel traps. Trap catches of cerambycids increased when we added the Ips spp. pheromone components (ipsenol or ipsdienol) or the host monoterpene (3-carene) to the woodborer standard. During the summers of 2003 and 2004, 18 cerambycid, 14 buprestid, and Þve siricid species were collected. One species of cerambycid, Monochamus clamator (LeConte), composed 49 and 40% of the 2003 and 2004 trap catches, respectively. Two other cerambycids, Acanthocinus obliquus (LeConte) and Acmaeops proteus (Kirby), also were frequently collected. Flight trap data indicated that some species were present throughout the summer, whereas others were caught only at the beginning or end of the summer.
