Pleistocene climate cycling and host plant association shaped the demographic history of the bark beetle Pityogenes chalcographus [PDF]

Scientific Reports, 2018
AbstractHistorical climatic oscillations and co-evolutionary dependencies were key evolutionary drivers shaping the current population structure of numerous organisms. Here, we present a genome-wide study on the biogeography of the bark beetle Pityogenes chalcographus, a common and widespread insect in Eurasia.

Polyploid spermatozoa in Pityogenes chalcographus and Ips typographus (Coleoptera: Scolytidae) [PDF]

European Journal of Entomology, 2004
Abnormal spermatogenesis in Pityogenes chalcographus (L.) and Ips typographus (L.) results in oversized spermatozoa in all the populations investigated. They can be identified by light microscopy and classified as 2n up to 16n polyploid.

Divergent Trends in Insect Disturbance Across Europe's Temperate and Boreal Forests. [PDF]

Glob Chang Biol
Across temperate and boreal Europe, tree mortality caused by insects has risen during the 21st century, yet interactions among insect species and their host trees are complex. While mortality from wood‐boring insects in conifers has increased, defoliation caused by multiple moth species has declined.

Mitochondrial phylogenies in the light of pseudogenes and Wolbachia: re-assessment of a bark beetle dataset [PDF]

ZooKeys, 2010
Phylogenetic studies based on mtDNA become increasingly questioned because of potential pitfalls due to mitochondrial pseudgenes and mitochondrial selective sweeps.

Negative impacts of insecticide-treated methods and slot traps for trapping of Ips cembrae on nontarget invertebrates. [PDF]

Pest Manag Sci
The negative impacts of using insecticide‐treated methods and slot traps against Ips cembrae were evaluated. Negative impacts on predator species of bark beetles such as Thanasimus formicarius and Red‐Listed species were described. Abstract BACKGROUND Ips cembrae is serious forest pest of European larch (Larix decidua).

Natural-history traits suspected behind interspecific variations of bark- and wood-boring beetles in response to trap size and design [PDF]

Scientific Reports
The performances of traps used for pest monitoring are not well understood. Variable trap sizes and shapes make cross-comparisons difficult. We tested with four Scolytinae species (Coleoptera, Curculionidae) a set of traps of the same model (fan-traps ...

Weak population genetic structure in Eurasian spruce bark beetle over large regional scales in Sweden. [PDF]

Ecol Evol, 2022
We investigated the genetic structure of the Eurasian spruce bark beetles over 800 km in Sweden using Restriction site associated DNA yielding thousands of markers across the genome. Our study show that population structure over this scale is weak, but we find indications of isolation by distance and that the Northern populations tended to be ...

Optimal tuning of PI based LF for three-phase SRF PLL synchronization system using pity beetle algorithm under grid abnormalities [PDF]

Scientific Reports
The importance of grid synchronization in recent years is primarily driven by the widespread integration of renewable energy sources (RES). As nations transition toward carbon–neutral power systems, the variable nature of renewables and the increasing ...

Three species of bark beetles (Coleoptera: Curculionidae, Scolytinae) on Pinus peuce in Pirin Mountains in Bulgaria [PDF]

Silva Balcanica, 2021
In 2020 and 2021, three species of bark beetles (Coleoptera: Curculionidae, Scolytinae) were established on Macedonian pine (Pinus peuce) in the region of Vihren hut in Pirin Mts.
