Insect Diversity in Forest Stands Damaged by .

Outbreaks of are of great concern, as their occurrence is predicted to become more intense and frequent due to a warming climate. A frequent treatment to control mass outbreaks of the pest is with the bioinsecticide Foray 76B. However, knowledge of how this treatment affects non-target insect species is limited.

Fungal Communities Associated with Siricid Wood Wasps: Focus on , , and .

We investigated the diversity and occurrence of wood wasps in Lithuania and determined communities of associated fungi. Trapping of wood wasps resulted in three different species, including , , and . Fungal culturing from adult females of mainly resulted in fungi from the genera and .

Biogeography of Fungal Communities Associated with L. and (L.) H. Karst. along the Latitudinal Gradient in Europe.

We assessed the diversity and composition of fungal communities in different functional tissues and the rhizosphere soil of and stands along the latitudinal gradient of these tree species distributions in Europe to model possible changes in fungal communities imposed by climate change. For each tree species, living needles, shoots, roots, and the rhizosphere soil were sampled and subjected to high-throughput sequencing. Results showed that the latitude and the host tree species had a limited effect on the diversity and composition of fungal communities, which were largely explained by the environmental variables of each site and the substrate they colonize.

Principal Drivers of Fungal Communities Associated with Needles, Shoots, Roots and Adjacent Soil of .

The plant- and soil-associated microbial communities are critical to plant health and their resilience to stressors, such as drought, pathogens, and pest outbreaks. A better understanding of the structure of microbial communities and how they are affected by different environmental factors is needed to predict and manage ecosystem responses to climate change. In this study, we carried out a country-wide analysis of fungal communities associated with growing under different environmental conditions.

First Report of the Larch Longhorn ( Weise, Coleoptera: Cerambycidae: Spondylidinae) on spp. in Lithuania.

is known to be native to the Alps in Europe where it breeds in European larch (), but it has spread to other areas and was reported in Poland, Sweden, Denmark and Belorussia. Although is considered an important secondary pest of spp., it can be particularly harmful to trees subjected to abiotic stress.

DNA-Metabarcoding of Belowground Fungal Communities in Bare-Root Forest Nurseries: Focus on Different Tree Species.

The production of tree seedlings in forest nurseries and their use in the replanting of clear-cut forest sites is a common practice in the temperate and boreal forests of Europe. Although conifers dominate on replanted sites, in recent years, deciduous tree species have received more attention due to their often-higher resilience to abiotic and biotic stress factors. The aim of the present study was to assess the belowground fungal communities of bare-root cultivated seedlings of , and in order to gain a better understanding of the associated fungi and oomycetes, and their potential effects on the seedling performance in forest nurseries and after outplanting.

Managed and Unmanaged Forest Stands Harbour Similar Diversity and Composition of the Phyllosphere and Soil Fungi.

The aim was to assess fungal communities associated with living needles and soil of in managed and unmanaged forest stands to get a better understanding of whether and how different intensities of forest management affects fungal diversity and community composition under the north temperate forest zone conditions. The study was carried out in three national parks in Lithuania. Each included five study sites in managed stands and five in unmanaged stands.

High-Throughput Sequencing Reveals Drastic Changes in Fungal Communities in the Phyllosphere of Norway Spruce (Picea abies) Following Invasion of the Spruce Bud Scale (Physokermes piceae).

The aim of this study was to assess the diversity and composition of fungal communities in damaged and undamaged shoots of Norway spruce (Picea abies) following recent invasion of the spruce bud scale (Physokermes piceae) in Lithuania. Sampling was done in July 2013 and included 50 random lateral shoots from ten random trees in each of five visually undamaged and five damaged 40-50-year-old pure stands of P. abies.
