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 ...

Reproductive Manipulators in the Bark Beetle Pityogenes chalcographus (Coleoptera: Curculionidae)-The Role of Cardinium, Rickettsia, Spiroplasma, and Wolbachia. [PDF]

J Insect Sci, 2018
Heritable bacterial endosymbionts can alter the biology of numerous arthropods. They can influence the reproductive outcome of infected hosts, thus affecting the ecology and evolution of various arthropod species. The spruce bark beetle Pityogenes chalcographus (L.) (Coleoptera: Curculionidae: Scolytinae) was reported to express partial, unidirectional

Bark beetles on logging residues of European larch: Effects of shading and diameter of logging residues on infestation density [PDF]

Agricultural and Forest Entomology, Volume 26, Issue 4, Page 457-469, November 2024.
1. Ips cembrae, an important pest of European larch (Larix decidua), has caused local outbreaks in the last two decades and is becoming increasingly important as the proportion of European larch in forests increases. 2. In 2021-2023, larch logs and piles

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.

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).

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 ...

Gradacija smrčinih potkornjaka na području Han Pijeska

Glasnik Šumarskog Fakulteta Univerziteta u Banjoj Luci, 2018
Rad se bavi utvrđivanjem brojnosti smrčinih potkornjaka (Ips typographus L., i Pityogenes chalcographus L.) i njihovom značaju u pojavi sušenja smrče, na području Han Pijeska. Smrča na ovom području ima veliki privredni i ekološki značaj.

Wood decomposition is increased by insect diversity, selection effects, and interactions between insects and microbes

Ecology, Volume 104, Issue 12, December 2023., 2023
Abstract Biodiversity drives ecosystem processes, but its influence on deadwood decomposition is poorly understood. To test the effects of insect diversity on wood decomposition, we conducted a mesocosm experiment manipulating the species richness and functional diversity of beetles.
