Comparative Analysis of Eight Mitogenomes of Bark Beetles and Their Phylogenetic Implications

open access: yesInsects, 2021
Many bark beetles of the subfamily Scolytinae are the most economically important insect pests of coniferous forests worldwide. In this study, we sequenced the mitochondrial genomes of eight bark beetle species, including Dendroctonus micans ...

Notes on Oriental Scolytus (Coleoptera: Curculionidae: Scolytinae)

open access: yesZoosystematica Rossica, 2016
New synonymies in the genus Scolytus Geoffroy, 1762 are established: S. koltzei Reitter, 1894 = S. yablonianus Murayama, 1943 = S. shanhaiensis Yin et Huang, 1980; S. ventrosus Schevyrew, 1890 = S. trispinosus Strohmeyer, 1908. Scolytus kononovi Kurentsov, 1941 is justified as a distinct species from S. semenovi (Spessivtsev, 1919).

Development and survival of the spruce bark beetle, Ips typographus (Coleoptera: Curculionidae: Scolytinae) at low temperatures in the laboratory and the field

open access: yesEuropean Journal of Entomology, 2017
The European spruce bark beetle (Ips typographus) is a highly destructive pest of spruce monocultures. Adult spruce bark beetles are well-adapted to survive over winter however, the ability of sub-adult stages to overwinter has not been clearly ...

Sanitation felling against the European spruce bark beetle: A matter of intensity and forest type Tagli fitosanitari contro il bostrico tipografo: una questione di intensità e tipologia forestale

open access: yesAgricultural and Forest Entomology, EarlyView.
We assess the effect of sanitation felling performed in 2022 in North‐Eastern Italy on bark beetle damage that occurred in 2023 across eight spruce forest types, as evaluated using multispectral satellite imagery. Bark beetle damage was reduced only at very high or very low sanitation felling rates.

The diversity of phoretic Mesostigmata on Ips typographus (Coleoptera: Scolytinae) caught in the Karkonosze forest

open access: yesEuropean Journal of Entomology, 2011
This study determined the scale of the phoresy of mesostigmatid mite by Ips typographus. Thirty pheromone traps in the Karkonosze National Park (Poland) caught 10,575 bark beetles on which there were 2,388 mesostigmatid mites belonging to eight species ...

Therapeutic Bark Gouging as an Effective Complement for the Management of Ips typographus and Pityogenes chalcographus While Preserving Habitat for Secondary Scolytine (Coleoptera: Curculionidae) Species

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Norway spruce will likely remain an important tree species in Europe over the next few decades despite efforts to transform forests and reduce its distribution range more to its natural range. Consequently, Ips typographus will remain one of the most relevant forest pests the management of which will become increasingly challenging due to ...

Cascading ecological effects caused by the establishment of the emerald ash borer Agrilus planipennis (Coleoptera: Buprestidae) in European Russia

open access: yesEuropean Journal of Entomology, 2015
Emerald ash borer, Agrilus planipennis, is a destructive invasive forest pest in North America and European Russia. This pest species is rapidly spreading in European Russia and is likely to arrive in other countries soon.

A Plant‐Based Platform for the Production of Bark Beetle Pheromones

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Bark beetle species of the genera Ips and Dendroctonus represent a threat to forests in both North America and Europe. Under normal circumstances, these beetles recycle dying trees into nutrients, but under certain conditions, growing populations can overcome healthy tree defenses and cause severe economic loss in forestry.

Community structure and reproductive biology of bark beetles (Coleoptera: Scolytinae) associated with Macaronesian Euphorbia shrubs

open access: yesEuropean Journal of Entomology, 2006
Dead wood of arborescent Euphorbia plants in the Macaronesian islands and Morocco has a diverse fauna of wood-boring beetles. Thirty-eight species were found in four species groups of Euphorbia, including 29 species of scolytine bark beetles, six species
