Population ofI. typographuswas studied in one locality with small-scale and short-term outbreak distant from large-scale and long-term outbreak area by several hundred meters. In total, ten spruce trees infested by the spruce bark beetle were examined. Always four stripes of bark (sample area) with the length equal to half the circumference of the trunk and the width of approximately 0.5 m were analyzed. The local spruce bark beetle population was characterized by high population density (1.5±1.2 entry holes per dm2), low number of eggs per female, and short maternal galleries. Relatively low

In recent decades, Norway spruce (Picea abies L. Karst.) forests of the High Tatra Mountains have suffered unprecedented tree mortality caused by European spruce bark beetle (Ips typographus L.). Analysis of the spatiotemporal pattern of bark beetle outbreaks across the landscape in consecutive years can provide new insights into the population dynamics of tree-killing insects. A bark beetle outbreak occurred in the High Tatra Mountains after a storm damaged more than 10,000 ha of forests in 2004.

Ips hauseri Reitter is the most important bark beetle on Picea schrenkiana in southeast Kazakhstan, but its biology, ecology, and outbreak dynamics are poorly known.

Only localized, low-severity bark beetle events occurred during the reconstructed period, indicating that extensive high-severity bark beetle outbreaks have not occurred historically in the Tien Shan spruce forest, unlike bark beetle outbreaks in spruce forests in North America, Europe, and Russia.

One part of the area was left without intervention and two types of intervention have been applied in other parts: (1) the classical forest approach, based on the logging of attacked trees and (2) “sanitation”, in which attacked trees were cut down, debarked, and left lying in the stand. The main goal of our research was to test the impact of nonintervention and both types of intervention on

The spruce beetle (Dendroctonus rufipennis Kirby) is the most destructive forest pest affecting mature spruce stands in British Columbia. A variety of responses to curtail the spread of bark beetle infestations exist. The responses, however, depend upon early detection of the infestations to minimize the cost of treatment and reduce losses of timber. It has been demonstrated that bark beetle-attacked spruce can be detected using visual interpretation of large scale colour infrared film (Churcher 1984; Churcher and McLean 1984; Murtha 1985; Murtha and Cozens 1985).

Abstract:
Учет короедов в ловушках значительно менее трудоемкий, чем прямой учет под корой деревьев [1]. Однако для эффективного ведения феромонного мониторинга популяции необходимо знать и учитывать погрешность, связанную с косвенным характером оценки численности типографа. Также важно конкретизировать продолжительность периода учетов, количество и схему расположения ловушек [2-4]. Основной задачей в итоге является повышение эффективности использования данных учетов короеда в феромонных ловушках для характеристики состояния популяции, динамики его численности и степени повреждения ельников.

Abstract:
The European spruce bark beetle (Ips typographus), widespread across Eurasia, is a major pest of coniferous forests in Europe, primarily attacking Norway spruce (Picea abies). High beetle populations can result in significant damage, especially following environmental stressors like storms. Although there has been no classical biological control program against I. typographus due to its non-invasive nature in other continents, the potential introduction of this beetle into new areas like North America could necessitate such measures. Natural enemies in Europe include numerous parasitoids, pred
