Previously, we described the heat shock response in dipteran species belonging to the family Stratiomyidae that develop in thermally and chemically contrasting habitats including highly aggressive ones. Although all species studied exhibit high constitutive levels of Hsp70 accompanied by exceptionally high thermotolerance, we also detected characteristic interspecies differences in heat shock protein (Hsp) expression and survival after severe heat shock. Here, we analyzed genomic libraries from two Stratiomyidae species from thermally and chemically contrasting habitats and determined the structure and organization of their hsp70 clusters.

New distributional data are provided for four species of the genus Tephritis Latreille, 1804, Sphenella marginata (Fallén, 1814) and Ensina sonchi (Linnaeus, 1767) (Diptera: Tephritidae). Tephritis separata Rondani, 1871 and T. mutabilis Merz, 1992 are recorded for the first time from Armenia and Transcaucasia, T. anthrax S. Korneyev et Evstigneev, 2019, from North Ossetia, and T. valida (Loew, 1858), from North Ossetia and Kabardino-Balkaria. Host plants are recorded for the larvae of each species, with Leontodon asperrimus (Willd.) Endl. being recorded for the first time as a host plant of T. mutabilis, and Caucasalia macrophylla (M. Bieb.) B. Nord. (= Senecio platyphyllus DC.) and Senecio kolenatianus C.A. Mey., as host plants of S. marginata. The morphological details of all six species of flies are illustrated in colour photos.

Techniques for sampling and preserving bloodsucking dipterans: mosquitoes, blackflies, biting midges, and horseflies (Diptera: Culicidae, Simuliidae, Ceratopogonidae, Tabanidae) are reviewed. We partly developed these techniques and used them in ecological, faunistic, and taxonomic studies requiring identification of specimens. Here, we describe the techniques used for adults, larvae, and pupae, both common to all the bloodsucking dipterans and specific to each group. For example, techniques for rearing larvae and pupae are described.

The first data on Anthomyzidae (Diptera) from montane and submontane peat bogs, peculiar isolated ecosystems of the North Caucasus, are given based on the faunistic research of 8 bogs situated in Ossetia and Kabardino-Balkaria at altitudes of 800–2290 m. Two species are recorded, the widespread eurytopic Anthomyza gracilis Fallén, 1823 and the boreo-montane A. dissors Collin, 1944. The latter species is recorded far beyond its known range extending it ca. 450 km south. The data on the Anthomyzidae in the Caucasus and Anthomyzidae associated with peat bogs are briefly reviewed. The distribution and origin of boreo-montane insects occurring in peat bogs of the Caucasus are briefly discussed.

A new genus of Chironomidae (Insecta: Diptera) is described based on a single incomplete pupa from Khutel Khara (lower part of the Tsagan Tsab Formation, Lower Cretaceous; Mongolia). The new...
