The Colorado potato beetle is one of the most devastating potato pests in the world. However, its viral pathogens, which might have potential in pest control, have remained unexplored. With high-throughput sequencing of Colorado potato beetle samples derived from prepupal larvae which died from an unknown infection, we have identified two previously unknown RNA viruses and assembled their nearly complete genome sequences.

Global fine-resolution data on springtail abundance and community structure.

Sci Data

January 2024

Department of Animal Ecology, Johann Friedrich Blumenbach Institute of Zoology and Anthropology, University of Göttingen, Göttingen, 37073, Germany.

Springtails (Collembola) inhabit soils from the Arctic to the Antarctic and comprise an estimated ~32% of all terrestrial arthropods on Earth. Here, we present a global, spatially-explicit database on springtail communities that includes 249,912 occurrences from 44,999 samples and 2,990 sites. These data are mainly raw sample-level records at the species level collected predominantly from private archives of the authors that were quality-controlled and taxonomically-standardised.

The feasibility of risk assessment of a Siberian silk moth ( Tschetv.) outbreak was analyzed by means of landscape and weather characteristics and tree condition parameters. Difficulties in detecting forest pest outbreaks (especially in Siberian conditions) are associated with the inability to conduct regular ground surveillance in taiga territories, which generally occupy more than 2 million km.

The entomopathogenic endophytic fungus can colonize plants resulting in growth promotion and protection against phytopathogenic microorganisms. However, physiological changes in potato plants () during this interaction are poorly understood. In the present work, gas chromatography-mass spectrometry and high-performance liquid chromatography were used to analyze sterol, fatty acid, and phenolic acid concentrations in potato plants inoculated with conidia in soil.

Environmental pollution with antibiotics can cause antibiotic resistance in microorganisms, including the intestinal microbiota of various insects. The effects of low-dose aminoglycoside antibiotic (amikacin) on the resident gut microbiota of , its digestion, its physiological parameters, and the resistance of this species to bacteria were investigated. Here, 16S rDNA analysis revealed that the number of non-dominant bacteria in the eighteenth generation of the wax moth treated with amikacin was increased 73 fold compared to , the dominant bacteria in the native line of the wax moth.

New data on distribution, ecology and biology of the rare extant species of the almost completely ancient family Prophalangopsidae (Orthoptera) are given. This montane species prefers humid areas with relatively low summer temperatures. Habits, mating behaviour and life history of are extremely similar to those of the North American representatives of the genus .

Infection of intestinal tissues with Wolbachia has been found in Habrobracon hebetor. There are not many studies on the relationship between Habrobracon and Wolbachia, and they focus predominantly on the sex index of an infected parasitoid, its fertility, and behavior. The actual role of Wolbachia in the biology of Habrobracon is not yet clear.

A taxonomic review was performed on cestodes of the genus Spassky, 1947 that parasitize different species of shrews in different regions of the northern Palearctic and in the Nearctic (Alaska, USA). Information on Palearctic cestodes published in various articles is summarized. An overview of the geographical distribution of the species is also presented.

Species of the genus are characterized by a multitrophic lifestyle of being arthropod parasites, rhizosphere colonizers, endophytes, and saprophytes. The process of adaptation to various organisms and substrates may lead to specific physiological alterations that can be elucidated by passaging through different hosts. Changes in virulence and cultivation properties of entomopathogenic fungi subcultured on different media or passaged through a live insect host are well known.

Article Synopsis
  • Recent genetic research has confirmed an increasing number of mole species, but cytogenetic data is still lacking for some.
  • The study describes a new karyotype for the small-toothed mole from Vietnam, revealing unique cytogenetic traits and comparing them with other mole species.
  • It identifies common chromosomal rearrangements and establishes a potential ancestral karyotype, noting that the small-toothed mole exhibits the fastest rate of chromosomal evolution among the moles studied.

Microplastics (MPs) are emergent pollutants in freshwater environments and may impact aquatic organisms, including those of nutritional value. The specific activities of digestive and antioxidant enzymes can be used as good bioindicators of the potential effects of MPs on fish in case of waterborne MP contamination. In this study, we used fluorescent polystyrene microplastics (PS-MPs) to analyze the alterations in enzyme activities in larvae of Gmelin (peled or Northern whitefish), one of the most valuable commercial fish species of Siberia.

It has been suggested that palms of the genus (Arecales: Arecaceae) or forms close to it were distributed in the Eocene of North America and Europe. Records of Metrioxenini (Belidae), which are monophages on these palms, confirm this assumption. A new species, Legalov, sp.

Now more than ever researchers provide more and more evidence that it is necessary to develop an ecologically friendly approach to pest control. This is reflected in a sharp increase in the value of the biological insecticide market in recent decades. In our study, we found a virus strain belonging to the genus (Reoviridae); the strain was isolated from , possessing attractive features as a candidate for mass production of biological agents for lepidopteran-pest control.

Intensification of crop cultivation can have detrimental environmental consequences that however can be prevented by monitoring of the specific biological indicators sensitive to changes in the ambient environment. In this study the impact of crop type (spring wheat and corn) and cultivation intensity on the community of ground beetles (Coleoptera: Carabidae) in the forest-steppe of Western Siberia was investigated. A total of 39 species from 15 genera were collected.
