Executive Summary (maximum 5 pages) The LifeELMIAS project objectives were to: 1) Eradicate the invasive alien species (IAS) of Dutch Elm Disease (DED) from Gotland; 2) Ensure favourable conservation status and sustainability of the wooded Annex 1 habitats affected by DED and ADB by implementing complementary management actions to make the habitats more robust trees for the future.; 3) Prepare a contingency plan for if DED eradication fails in the short term. This will provide an insurance policy for the Natura 2000 sites. 4) Implement an information programme to increase the knowledge and understanding of the problems related to Invasive Alien Species and the impact on biodiversity. Key deliverables and outputs: 1) The eradication or control of DED 2) The distribution of elm mapped, all trees identified as infected with DED felled and destroyed. 3) The ecology of Scolytus multistriatus on Gotland better understood and the DNA provenance of the DED pathogen established. 4) A control programme for the import of time established 5) A database and site seed bank with at least 100 apparently disease resistant ash genotypes established 6) 25 restoration plans produced and 30 ha of Annex I habitat restored, 200 trees veteranized, 400 trees pollarded, 700 trees cleared around and 500 trees protected from grazing animals, 800 trees vaccinated and evaluated. 7) 25 baseline survey descriptions for the Natura 200 sites produced. Monitoring of mortality rates of veteran trees and their replacements as well as the health of the trees subject to the treatments. Monitoring of lichens, Ficedula albicollis and bats at the beginning and the end of the project. 8) Evaluation of the socioeconomic impact of the project as well as the assessment of the project impact on ecosystem functions. 9) 20 notice boards put up, website produced, at least 6 press releases, a leaflet and a layman’s report produced. 500 people taken part in visitor events and training sessions. A workshop with at least 100 delegates and a final conference with at least one hundred delegates. LifeELMIAS is now finished. The project has been successful in identifying and eradicating infected and risk trees, keeping DED under control, we have developed and improved methods for how to combat DED and have built capacity and knowledge within the work team. The project has also been effective in reaching out with communication to the general public and stakeholders. Three scenarios were proposed in the application: 1) DED eradicated within the timescale of the project; 2) DED cannot be eradicated from Gotland 3) DED is not eradicated by the end of the project, but the disease has been

  • Biology and Management of the Dutch Elm Disease Vector, Hylurgopinus Rufipes Eichhoff (Coleoptera: Curculionidae) in Manitoba By
    Biology and Management of the Dutch Elm Disease Vector, Hylurgopinus rufipes Eichhoff (Coleoptera: Curculionidae) in Manitoba by Sunday Oghiakhe A thesis submitted to the Faculty of Graduate Studies of The University of Manitoba in partial fulfilment of the requirements of the degree of Doctor of Philosophy Department of Entomology University of Manitoba Winnipeg Copyright © 2014 Sunday Oghiakhe Abstract Hylurgopinus rufipes, the native elm bark beetle (NEBB), is the major vector of Dutch elm disease (DED) in Manitoba. Dissections of American elms (Ulmus americana), in the same year as DED symptoms appeared in them, showed that NEBB constructed brood galleries in which a generation completed development, and adult NEBB carrying DED spores would probably leave the newly-symptomatic trees. Rapid removal of freshly diseased trees, completed by mid-August, will prevent spore-bearing NEBB emergence, and is recommended. The relationship between presence of NEBB in stained branch sections and the total number of NEEB per tree could be the basis for methods to prioritize trees for rapid removal. Numbers and densities of overwintering NEBB in elm trees decreased with increasing height, with >70% of the population overwintering above ground doing so in the basal 15 cm. Substantial numbers of NEBB overwinter below the soil surface, and could be unaffected by basal spraying. Mark-recapture studies showed that frequency of spore bearing by overwintering beetles averaged 45% for the wild population and 2% for marked NEBB released from disease-free logs. Most NEBB overwintered close to their emergence site, but some traveled ≥4.8 km before wintering. Studies comparing efficacy of insecticides showed that chlorpyrifos gave 100% control of overwintering NEBB for two years as did bifenthrin: however, permethrin and carbaryl provided transient efficacy.

  • Dutch Elm Disease Pathogen Transmission by the Banded Elm Bark Beetle Scolytus Schevyrewi

Forest Service, Rocky Mountain Forest Research Station, Fort Collins, CO USA; 3E-mail: [email protected] (for correspondence) Summary Dutch Elm Disease (DED) is a vascular wilt disease of Ulmus species (elms) incited in North America primarily by the exotic fungus Ophios- toma novo-ulmi. The pathogen is transmitted via root grafts and elm bark beetle vectors, including the native North American elm bark beetle, Hylurgopinus rufipes and the exotic smaller European elm bark beetle, Scolytus multistriatus. The banded elm bark beetle, Scolytus schevyrewi, is an exotic Asian bark beetle that is now apparently the dominant elm bark beetle in the Rocky Mountain region of the USA. It is not known if S. schevyrewi will have an equivalent vector competence or if management recommendations need to be updated. Thus the study objectives were to: (i) determine the type and size of wounds made by adult S. schevyrewi on branches of Ulmus americana and (ii) determine if adult S. schevyrewi can transfer the pathogen to American elms during maturation feeding. To determine the DED vectoring capability of S. schevyrewi, newly emerged adults were infested with spores of Ophiostoma novo-ulmi and then placed with either in-vivo or in-vitro branches of American elm trees.

Received: 9 October 2020; Accepted: 28 October 2020; Published: 30 October 2020 Simple Summary: Several wood-associated insects are inadvertently introduced every year within wood-packaging materials used in international trade. These insects can cause impressive economic and ecological damage in the invaded environment. Thus, several countries use traps baited with pheromones and plant volatiles at ports of entry and surrounding natural areas to intercept incoming exotic species soon after their arrival and thereby reduce the likelihood of their establishment. In this study, we investigated the performance of eight trap colors in attracting jewel beetles and bark and ambrosia beetles to test if the trap colors currently used in survey programs worldwide are the most efficient for trapping these potential forest pests. In addition, we tested whether trap colors can be exploited to minimize inadvertent removal of their natural enemies.

Abstract 1 The species assemblages and abundance of phoretic mites and nematodes associated with the elm bark beetles, Scolytus multistriatus and Scolytus pygmaeus, were studied in Austria. 2 A total of 3922 individual mites were recorded from 144 adults of S. multi- striatus and 178 adults of S. pygmaeus. The species spectrum was identical and the relative abundance of mites was very similar for both species of scolytids. Nine mite species, Pyemotes scolyti, Pseudotarsonemoides eccoptogasteri, Trichouropoda bipilis, Tarsonemus crassus, Proctolaelaps eccoptogasteris, Proctolaelaps scolyti, Chelacheles michalskii,nr.Eueremaeussp. and Elattoma sp. were detected. Two of the nine species, nr. Eueremaeus sp. and Elattoma sp., are documented here as new associates of Scolytus spp. 3 Pyemotes scolyti was the most frequent mite species, and Ps. eccoptogasteri and T. bipilis were relatively common, whereas the other mites occurred occasion- ally or were rare. 4 The trophic roles of most of the mites associated with S. multistriatus and S. pygmaeus are poorly known, but they may include fungivores, parasitoids of bark beetle broods, predators of bark beetle broods and/or mites and/or nematodes.

Davis, Arthropod Diagnostician DID YOU KNOW? • Two major bark beetle species attack elm trees in Utah; both can transmit Dutch Elm Disease (DED) , leading to tree death, decline, or chronic stress. • Preventive treatments such as foliar insecticide applications, severing root graphs between trees, injectable fungicides, and proper pruning of af- fected areas can minimize transmission of DED. • New, DED-resistant American elm cultivars are available for purchase; look for ‘Valley Forge’ and ‘New Harmony’ at your local nursery.
