Chromosome Number in the Smaller European Elm Bark Beetle, Scolytus multistriatus1, 2

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

Statistical Correlations Between GLC Assay and Smaller European Elm Bark Beetle1 Bioassay2

American elm trees, Ulmus americana L., were sprayed with methoxychlor by helicopter or mist blower, and twig crotches were collected from sprayed trees for bio­ assay of Scolytus multistriatus (Marsham) and GLC as­ say. Correlations established between the 2 assays were Dutch elm disease, caused by the fungus Cerato­ cystis ulmi (Buisman) C. Moreau, is a serious shade tree problem in the Unite...

The Banded Elm Bark Beetle, Scolytus schevyrewi Semenov (Coleoptera, Curculionidae, Scolytinae) in North America: a taxonomic review and modifications to the Wood (1982) key to the species of Scolytus Geoffroy in North and Central America

In 2003, an Asian bark beetle, Scolytus schevyrewi Semenov (Coleoptera: Curculionidae: Scolytinae), the banded elm bark beetle, was detected for the first time in North America. This paper modifies the Wood (1982) key to the species of Scolytus Geoffroy to enable identification of Scolytus schevyrewi in North and Central America. Variation of diagnostic characters in Scolytus schevyrewi is disc...

Volatiles released from oak, a host tree for the bark beetle Scolytus intricatus.

Volatile compounds emitted in different phases of oak (Quercus robur) development (bark, unopened buds, young developing leaves, and blossoms) were analyzed with the aim of finding possible host-plant attractants for the European oak bark beetle, Scolytus intricatus. Complex mixtures of aliphatic, aromatic, and terpenoid compounds were identified in the samples. (E)-2-Hexenal and hexanal domina...

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...
