The European spruce bark beetle, Ips typographus, is a serious pest of spruce forests in Europe, and its invasion and development inside spruce tissues are facilitated by microorganisms. We investigated the core gut bacterial and fungal microbiomes of I. typographus throughout its life cycle in spring and summer generations. We used cultivation tec...
Spruce bark beetle Ips typographus can trigger outbreaks on spruce that results in significant losses in the forest industry. It has been suggested that symbiotic microorganisms inhabiting the gut of bark beetles facilitate the colonization of plant tissues as they play a role in the detoxification of plant secondary metabolites, degrade plant cell...
Ips typographus, the most serious pest of spruce forests in Europe, is associated with microorganisms facilitating its invasion and development inside spruce tissues. Despite the importance of I. typographus, little is known about its core gut microbiome. Hereby, we describe the composition of bacterial and fungal microbiomes throughout I. typograp...
updated presentation from March (FABI seminar) presented on AMC 2021
Yeasts dominate core gut microbiome of bark beetle Ips typographus. Proportions of the dominant yeast species change with season. The dominant yeasts probably participate in beetle nourishment and aid with detoxification of plant tissues.

Abstract
The evolutionary success of termites has been driven largely by a complex communication system operated by a rich set of exocrine glands. As many as 20 different exocrine organs are known in termites. While some of these organs are relatively well known, only anecdotal observations exist for others. One of the exocrine organs that has rece...
A phylogeny of the Torymidae (Chalcidoidea) is estimated using 4734 nucleotides from five genes. Twelve outgroups and 235 ingroup taxa are used, representing about 70% of the recognized genera. Our analyses do not recover Torymidae as monophyletic and we recognize instead two families: Megastigmidae (stat. rev.) and Torymidae s.s. (stat. rev.). Wit...
The higher termites (Termitidae) are keystone species and ecosystem engineers. They have exceptional biomass and play important roles in decomposition of dead plant matter, in soil manipulation, and as the primary food for many animals, especially in the tropics. Higher termites are most diverse in rainforests, with estimated origins in the late Eo...
Chileana Janšta & Křížková gen. nov. and four new species, C. cyanea Janšta & Křížková sp. nov., C. maculata Janšta & Křížková sp. nov., C. tricarinata Janšta & Křížková sp. nov. and C. penai Janšta & Křížková sp. nov., all from Chile, are described. The placement of this new genus within the tribe Monodontomerini is discussed and several character...
