Elm bark disease in Australia

Study on two species of Ophiostoma in relation with Dutch elm disease in Iran

An investigation was carried out in some areas of Golestan Province including: Loveh forest, Soosara, Daland forest park, Tooskestan; Gilan Province including Siahkal and Asalem forests; Arasbaran and landscape of urban trees during 1999–2007. In this investigation, based on some morphological, physiological and molecular characteristics and also comparison with standard isolates two species Op...

Exotic Invasive Elm Bark Beetle, Scolytus kirschii, Detected in South Africa

Mariannaea samuelsii Isolated from a Bark Beetle-Infested Elm Tree in Korea

During an investigation of fungi from an elm tree infested with bark beetles in Korea, one isolate, DUCC401, was isolated from elm wood. Based on morphological characteristics and phylogenetic analysis of the internal transcribed spacer and 28S rDNA (large subunit) sequences, the isolate, DUCC401, was identified as Mariannaea samuelsii. Mycelia of the fungus grew faster on malt extract agar tha...

Semiochemical-mediated flight strategies of two invasive elm bark beetles: a potential factor in competitive displacement.

A seven-state survey showed that the recently detected invasive Asian banded elm bark beetle, Scolytus schevyrewi Semenov, was abundant in areas of Colorado and Wyoming, whereas the long-established European elm bark beetle, S. multistriatus (Marsham), was not as abundant. In one of a series of studies to evaluate whether S. schevyrewi is competitively displacing S. multistriatus in their North...

ELM physics and ELM mitigation in ITER

Edge Localised Modes are characteristic of the high performance, H-mode plasmas that are required for the attainment of Q = 10/500MW fusion power in the first phase of ITER operation. The energy released by a type I ELM, in good confinement plasmas, is typically 510% of the plasma stored energy; with low collisionality plasmas at the upper end of the range. Dimensional analysis, experiment and ...
