Abstract:

The article uncovers some questions of the labor history of printing production workers in the Crimean ASSR in 1920–1930s. The aim of the article is investigation of the staff structure of the Crimean ASSR printing industry workers in comparison with the national structure. The objectives of the study are to examine the dynamics of the number of workers in the printing industry of the Crimea, to analyze the proportion of women, national personnel (Crimean Tatars), adolescents, skilled workers in the overall structure of the printing industry workers of the Crimean ASSR, and to compare the obta

Arthropods were collected as they emerged from the bolts in autumn and the following spring. At least 32 arthropod species were collected, of which 17 are known to feed on bark beetle brood.

Abstract:

Ips typographus (Coleoptera, Scolytinae) is a spruce-infesting bark beetle that occurs throughout Europe and Asia. The beetle can cause considerable damage, especially when colonized trees are stressed and beetle populations increase. Although some studies have shown that populations of I. typographus in Europe, China and Japan are genetically distinct, these populations are biologically similar, including a strong association with ophiostomatoid fungi. To date, only two Leptographium spp. have been reported from the beetle in China, while 40 species have been reported from Europe and 13 from

Abstract:

Outbreaks of the Eurasian spruce bark beetle (Ips typographus) have decimated millions of hectares of conifer forests in Europe in recent years. The ability of these 4.0 to 5.5 mm long insects to kill mature trees over a short period has been sometimes ascribed to two main factors: (1) mass attacks on the host tree to overcome tree defenses and (2) the presence of fungal symbionts that support successful beetle development in the tree. While the role of pheromones in coordinating mass attacks has been well studied, the role of chemical communication in maintaining the fungal symbiosis is poorl

Abstract. New (a)biotic conditions resulting from climate change are expected to change disturbance dynamics, such as windthrow, forest fires, droughts, and insect outbreaks, and their interactions. These unprecedented natural disturbance dynamics might alter the capability of forest ecosystems to buffer atmospheric CO2 increases, potentially leading forests to transform from sinks into sources of CO2. This study aims to enhance the ORCHIDEE land surface model to study the impacts of climate change on the dynamics of the bark beetle, Ips typographus, and subsequent effects on forest functionin

AbstractDamages by wind and by European spruce bark beetle (I. typographusL.) were compared on the basis of the reports about the occurrence of harmful forest agents for the period 1964−1991 across former regional state forest directorates. In the given period, the quantity of salvage logging (70 million m3) was more than five times that of sanitation felling (13 million m3). Damage intensity increased over the decades. Using a cross-correlation function between the time series, an increase in the abundance ofI. typographusdue to windfall was demonstrated with a delay of 1–3 years. Wind damage

Abstract:

Gram-negative-staining bacteria that were resistant to monoterpene myrcene (7-methyl-3-methylene-1.6-octadiene, C10H16, at concentrations of up to 10 µl ml−1 in TSB) were isolated from the gut contents of adult bark beetles Ips typographus (Coleoptera, Scolytidae). The beetles were collected from the bark of Norway spruce (Picea abies) in Lithuania. Bark beetles feed on conifers, which produce myrcene among many other defensive compounds. It has been suggested that the micro-organisms present within the beetles’ guts could be involved in their resistance towards this plant defensive compound.

(Uploaded by Plazi for the Bat Literature Project) Natural forest disturbances are increasingly common due to ongoing climate changes but their impact on most of forest organisms is poorly studied. Here we investigate the link between spruce bark beetle Ips typographus outbreak in 2011–2017 in Białowiez˙a Primeval Forest (Poland) and activity of a forest bat of conservation concern: the western barbastelle Barbastella barbastellus. Bats were surveyed by recording ultrasound signals on 8 transects (3 km each) in a mixed coniferous and deciduous forest with a different share of Norway spruce. Th

Abstract. Biogenic volatile organic compound (BVOC) emissions from trees subjected to biotic stress are higher compared to healthy trees, and they may also have a different compound composition. This in turn affects atmospheric chemistry and can lead to either positive or negative feedback to the climate. Climate change favors the abundance of the European spruce bark beetle (Ips typographus) which attacks the bark of Norway spruce (Picea abies) trees, causing induced BVOC emissions from the trees as a response to the insect stress.

Abstract:

The spruce bark beetle, Ips typographus, is causing severe economic losses during epidemic phases triggered by droughts and/or windstorms. Sanitation felling and salvage logging are usually the most recommended strategies to limit the damages. However, any additional control method to limit the economic impact of an outbreak would be welcome. In this respect, the efficiency of pheromone trapping is still controversial or poorly documented. In this 2-year study (2020–2021), at the peak of a severe outbreak in Belgium, we quantified the wood volume and presence/absence of new attacks at 126 site

The tested hypotheses were that light traps have a valuable broad-spectrum attraction and their trapping performance differs between empty or loaded containers. The optimal trap density in a c

Abstract:

Plant defence mechanisms, including physical barriers like toughened bark and chemical defences like allelochemicals, are essential for protecting them against pests. Trees allocate non-structural carbohydrates (NSCs) to produce secondary metabolites like monoterpenes, which increase during biotic stress to fend off pests like the Eurasian spruce bark beetle, ESBB (Ips typographus). Despite these defences, the ESBB infests Norway spruce, causing significant ecological damage by exploiting weakened trees and using pheromones for aggregation.

Background. Pine bark beetle Ips acuminatus (Gyllenhal, 1827) is one of the most harmful pests of pine trees as it affects the phloem of the upper part of the stem and branches, disrupting the flow of nutrients and water to the crown. I. acuminatus feeds by plant tissues rich in starch, so α-amylases must play a pivotal role in the carbohydrate metabolism of these insects. However, in conifer bark beetles, α-amylases remain poorly understood. Materials and Methods.

Eurasian spruce bark beetle, Ips typographus is a destructive pest of the Norway spruce (Picea abies). Recent outbreaks in Europe have been attributed to global warming and other anthropogenic impacts. Bark beetles are guided by multiple complex olfactory cues throughout their life cycle. Male-produced aggregation pheromones, comprising 2-methyl-3-buten-2-ol and cis-verbenol, have been identified as the most powerful attractants for dispersing conspecifics. In addition to host trees, bark beetles interact with multiple organisms, including symbiotic ophiostomatoid fungi, which may promote beet
