Hermetia illucens (Diptera: Stratiomyidae, Linnaeus, 1978), commonly known as the black soldier fly (BSF), is a saprophytic insect, which in recent years has attracted significant attention from both the scientific community and industry. The unrestrained appetite of the larvae, the ability to forage on various organic waste, and the rapid growth and low environmental impact of its breeding has made it one of the insect species bred on an industrial scale, in the hope of producing fodder or other ingredients for various animals. The variety of research related to this insect has shown that feed production is not the only benefit of its use. H. illucens has many features and properties that could be of interest from the point of view of many other industries. Biomass utilization, chitin and chitosan source, biogas, and biodiesel production, entomoremediation, the antimicrobial properties of its peptides, and the fertilizer potential of its wastes, are just some of its potential uses. This review brings together the work of four years of study into H. illucens. It summarizes the current state of knowledge and introduces the characteristics of this insect that may be helpful in managing its breeding, as well as its use in agro-industrial fields. Knowledge gaps and under-studied areas were also highlighted, which could help identify future research directions.
We studied the effect of climate variations on the structure of the assemblage of ground beetles (Coleoptera: Carabidae) in a wetland and surrounding watershed forest. We analyzed the changes in the structure of the assemblage of ground beetles provoked by a two-year dry period against the background of studies carried out during the two-year wet period. Aridization influenced the structure of the assemblage of ground beetles more in wetlands than in forests. It was shown that despite the stabilizing effect of the forest on the structure of assemblages of terrestrial arthropods, the two-year dry period had a negative impact on the assemblage of ground beetles in the studied area. The Simpson dominance index of 4.9 during the wet season increased to 7.2 during the drought period. Although the total number of species during the dry period did not significantly decrease in comparison with the wet period—from 30 to 27 species—changes occurred in the trophic structure: during the drought period, the number of predators decreased. It is concluded that the resistance of forest habitats to climate aridization is somewhat exaggerated and, very likely, the structure of the community of arthropods in forests will change significantly.

The first record of the tribe Paussini Latreille is reported based on a specimen from late Eocene Rovno amber. It is the first known close relative of the genus Eohomopterus (subtribe Carabidomemnina) in the Old World. The recent and Neogene distribution of Eohomopterus is Neotropical, with extant representatives in Ecuador, Brazil and the West Indies, and extinct species in Dominican and Mexican amber. The occurrence of the Neotropical Carabidomemnina in Rovno amber and the presence of the Oriental Protopaussini in Dominican amber are of significant interest as evidence of the probable transarctic migrations of their ant host in the early Eocene.
The first ground beetle, Antephilorhizus pripiatiensis gen. et sp. nov., is described from late Eocene Rovno amber. The new genus Antephilorhizus is placed within the subtribe Dromiusina Bonelli, 1810 and similar to the extant Philorhizus Hope, but it differs by the weakly obliquely truncate apex of the elytra, unidentate mentum tooth, four setae on the apical margin of the labrum, tarsomere V of the hind tarsus is shorter than tarsomere I, and a series of umbilicate setae from 4 + 1 + 4 + 1. Comparative analysis is provided. http://www.zoobank.org/urn:lsid:zoobank.org:pub:E8E0F3EE-F0E6-42D5-9C45-ADDF1B22773C
†Antephilorhizus zerovae Kirichenko-Babko & Perkovsky sp. nov., the second species of this genus, is described from the Rovno amber (Ukraine). The new species is rather similar to the A. pripiatiensis Kirichenko-Babko & Perkovsky, 2021. The new taxon is compared with lebiines from Baltic amber. Based on a new data, the diagnosis of the genus †Antephilorhizus Kirichenko-Babko, 2021 is clarified and a key to both species of genus is given.
The consequences of global climate change are a decrease in precipitation as well as an increase in the length of the period with high temperatures from spring to autumn. The climate change intensified the negative consequences of land reclamation and regulation of rivers by dams in Ukraine in...
