Formica polyctena belongs to the red wood ant species group. Its nests provide a stable, food rich, and temperature humidity controlled environment, utilized by wide range of species, called myrmecophiles. Here, we used high-throughput sequencing 16S rRNA gene on Illumina platform for identification microbiome profiles six selected myrmecophilous beetles (Dendrophilus pygmaeus, Leptacinus formicetorum, Monotoma angusticollis, Myrmechixenus subterraneus, Ptenidium formicetorum Thiasophila...

Saproxylic beetles play a crucial role in key processes occurring forest ecosystems, and together with fungi contribute to the decomposition mineralization of wood. Among this group are mycetophilic which associate wood-decaying use fruiting body for nourishment development. Therefore, their feeding strategy (especially case fungivorous species) requires special digestive capabilities take advantage nutritional value fungal tissue. Although polypore-beetle associations have been investigated...

Recent years have witnessed a fall in the numbers of bee colonies worldwide. To large extent, this is due to diseases affecting honeybees. One such disease nosemosis, which caused by fungi from genus Nosema. The antibiotic fumagallin used be administered treat but as it was found capable being transferred products, practice has ceased. We therefore focused on natural substances for treating disease, among them, aqueous extracts nest carton produced jet-black ant (Lasius fuliginosus). tested...

This study summarises information on the occurrence of Myrmecophilus acervorum in Poland years 1851–2022. We collected about 143 localities: 40 from literature and 103 unpublished. is reported seven new regions: Baltic Coast, Białowieża Primeval Forest, Eastern Sudety Mts, Kraków-Wieluń Upland, Podlasie Lowland, Sandomierska Lowland Trzebnickie Hills. While until 2010 observations were rare (35 localities), 2011–2022 species was found 108 localities. A total 443 individuals M. observed...

The paper describes the external structures of late larval stages two Palearctic myrmecophilous staphylinids: Amidobiatalpa and Oxypodahaemorrhoa associated with Formicarufa species group. This is first-ever description larva Amidobia, only complete, detailed account morphology this developmental stage in genus Oxypoda currently available. For first time these genera, 13 10 diagnostic features, respectively, are proposed. Morphological differences have been established between known newly...

Myrmecophilous insects depend on their ant hosts during at least part of life cycle. Lasius ants appear to be primarily involved as host in myrmecophilous interactions, especially with aphids and beetles, e.g. staphylinid. Pella laticollis is a rove beetle having close ecological association fuliginosus, which correlated its behavior adapted avoid attack. Microorganisms can also play an important role the maintenance such relationships. We used 16S rRNA sequencing Illumina MiSeq platform...

Myrmecophilus acervorum, previously considered a parthenogenetic species widely-distributed in Europe, has been observed to have both sexes populations inhabiting the central part of distribution range. Specimens from those heterosexual found being infected with Wolbachia. New mitochondrial data (COI and 16S markers) revealed well-supported differentiation M. acervorum western Polesie (Poland) southern Europe. In turn, analyses EF1α marker support hypothesis on unfinished lineage sorting at...

Detailed external structures of mature larvae two subcortical species, Nudobius lentus (Gravenhorst) and Gabrius splendidulus (Gravenhorst), are re-described illustrated based on light scanning electron microscopy. A combination characters to distinguish the from those other genera within tribe Xantholinini for N. lentus, subtribe Philonthina G. is presented. Diagnostic larval identify species given.

This is the first morphological description of mature larva (L2) genus Pseudomedon, belonging to tribe Lathrobiini and subtribe Medonina. Detailed illustrations its structural features are provided. Based on earlier published new data, 10 18 diagnostic larval characters for Paederinae respectively, proposed. In light tribal system established subfamily based current knowledge (including Pseudomedon) concerning morphology these staphylinids, a comparative analysis traits at different...

The aim of the study was to describe morphological ultrastructure, including chaetotaxy, previously unknown early (L1) and late (L2-3) larval instars Phloeonomus punctipennis. diagnostic characters for genus are proposed first time. Morphological differences between L1 L3 refer only proportion length individual parts antennae legs as well urogomphi their subapical setae. chaetotaxy mature larvae P. punctipennis Dalotia coriaria, a model aleocharine larvae, is compared. Despite some...

Long-term evaluation of the visual refractive outcomes and quality life after implantation WIOL-CF (Medicem, Czech Republic) in both eyes.retrospective, nonrandomized noncomparative case series.50 eyes 25 patients, including 11 women (44%) 14 men (56%). The age range patients was 38 to 77 years (mean 55.48 ± 10.97 years). All underwent bilateral WIOL-CF. Exclusion criteria were previous ocular surgeries except for cataract surgery lens exchange, irregular corneal astigmatism >1.0 diopter,...

Six new water extracts (E1–E6) were obtained from nest carton produced by jet black ants Lasius fuliginosus and tested for their biochemical bioactive properties, including antioxidative anticancer effects. The present study demonstrated significant qualitative quantitative differences in the content of individual constituents, as well properties between investigated samples. All antioxidant (determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH)...

This is the first record of European yellow sac spider Cheiracanthium punctorium (Villers, 1789) from Lublin Upland (SE Poland). A dozen or so silk nests containing these spiders were found among goldenrod stems (Solidago sp.) on a dry meadow near Chodel, village in valley River Chodelka 8 October 2021.

The authors discuss the material collected in Suwalski Landscape Park years 2009 and 2011-2013, almost exclusively obtained from standing waters. At 29 study sites, 1 204 individuals representing 109 species 12 families were caught, of which 55 have been recorded for first time examined area. most valuable were: Gyrinus distinctus, Haliplus fulvicollis, H. variegatus, Ilybius erichsoni, Graphoderus austriacus, Hydroporus glabriusculus, incognitus, Hydrochus ignicollis, megaphallus, Spercheus...

Abstract The paper presents the first records of tineid moth Nemapogon gliriella in Poland. Eleven specimens were reared from sporocarps Stereum hirsutum and S. rugosum growing on dead oak hazel wood. Issues concerning morphological similarity with other species genus are briefly discussed. basic ecological characteristics presented.

Considered rare weevil species Lixus fasciculatus Boheman, 1836 (Curculionidae) was recorded on the Czechowskie Hills in Lublin (E Poland) 2022. More than 30 adults were found, as well numerous L1 – L3 larvae and eggs. All developmental stadia found mugwort (Artemisia vulgaris) growing localities with xerothermic or ruderal plant communities.

Abstract An ethanol extract of Lasius fuliginosus ant nests was found to be highly effective against nosemosis in apiary honey bees. Two concentrations the (300 mg and 1500 mg/100 ml sugar syrup) were tested on bees infected by nosemosis, both significantly reduced number Vairimorpha ceranae DNA copies. Administration also had a positive effect bees’ immune system, increasing expression genes encoding peptides (abaecin, defensin-1, hymenoptaecin). The subjected detailed biochemical analysis...
