All the five species of the genus Thaumatomyia Zenker, 1833 present in Middle Asia have predatory larvae feeding on root aphids. Four species of this genus were recorded in the agrobiocenoses of Uzbekistan and Kyrgyzstan: 2 species (Th. sulcifrons and Th. notata) in the rainfed zone of Uzbekistan, and all the 4 species (Th. glabra, Th. rufa, Th. sulcifrons, and Th. notata) in the beet growing regions of Kyrgyzstan. The remaining species Th. hallandica was recorded only in the mountains of Kyrgyzstan. Adults of Thaumatomyia prefer cereals, alfalfa, sugar beet, umbellifers, and flowering forage herbs. Of the 47 species of root aphids recorded in Uzbekistan and Kyrgyzstan, 38 species develop on cultural plants and weed while 9 species occur on wild shrubs, semi-shrubs, and trees. All the Middle Asian Thaumatomyia species are polyphagous; the larvae of Th. glabra feed on 31, Th. rufa on 22, Th. sulcifrons on 35, Th. notata on 27, and Th. hallandica on 13 species of root aphids. The activity of Thaumatomyia larvae is an important factor of control of the sugar-beet root aphid Pemphigus fuscicornis (Koch) and the bean root aphid Smynthurodes betae Westwood in sugar beet crops in Kyrgyzstan. The efficiency of Thaumatomyia larvae as root aphid control agents was much higher in sugar beet crops than in cereal fields within the rainfed agriculture zone of Uzbekistan.

Biotopic relations of the larvae of nine species of the flower fly genus Brachyopa Meigen, 1822 with primary (aggressive) and ambrosia xylophagous insects, as well as with phloeophages are revealed. Brachyopa larvae mainly feed on fresh liquid sap accumulated on damaged tree trunks. The main and additional habitats for larval development are considered for the first time.

Collections using yellow water traps revealed from 20 to 43 species of aphids on seed potato plantings in the farms of Northwest Russia in 2013–2017. Among them, from 2 to 5 species were vectors of potato viruses; aphids of these species together comprised 12.5–36% of the total number of captured aphids. The remaining 18–38 aphid species attracted to yellow traps were associated with vegetable, fruit and berry crops, weeds, trees, and shrubs surrounding potato plantings in the study areas. The species number and abundance of aphids depended on weather conditions, insecticide treatments, and the presence of home gardens near the traps. Up to 7 aphid species feeding on potatoes were recorded using the “100 leaves” sampling method; 6 of them are vectors of viral potato diseases: Aphis fabae Scop., A. nasturtii Kalt., A. frangulae Kalt., Aulacorthum solani Kalt., Macrosiphum euphorbiae Thomas, and Myzus persicae Sulz.

Data on the taxonomic composition, distribution, ecology, and phylogenetic relationships of 35 species and 20 subspecies of Carabidae endemic to the Sikhote-Alin Mountains are given. Of the 32 tribes and 94 genera of ground beetles recorded from the Sikhote-Alin, only 7 tribes and 11 genera contain endemics. The greatest number of endemics is found in the tribes Pterostichini (15 species and 9 subspecies), Trechini (10 species and 5 subspecies), Carabini (6 subspecies), and Nebriini (4 species). The tribes Platynini, Zabrini, and Lebiini have 2 endemic species each in the Sikhote-Alin fauna. Of the 11 genera containing the Sikhote-Alin endemics, Pterostichus Bonelli, 1810 comprises 15 species and 9 subspecies, Trechus Clairville, 1806 has 6 species and 5 subspecies, and Carabus Linnaeus, 1758 has 6 subspecies. The remaining 8 genera together include 14 endemic species: 6 of them have 2 endemic species each in the Sikhote-Alin fauna, and 2 genera have 1 endemic species each.

Data on the distribution of 24 species of carabid beetles in Xinjiang Uygur Autonomous Region of China are presented. Twenty taxa are newly recorded from China: Nebria (Eunebria) psammophila Solsky, 1874, N. (Eunebria) picta Semenov, 1891, Calosoma (Caminara) imbricatum deserticola Semenov, 1897, Carabus (Morphocarabus) henningi henningi Fischer von Waldheim, 1817, Scarites (s. str.) cylindronotus Faldermann, 1836, Apotomus testaceus Dejean, 1825, Pterostichus (Platysma) insignicollis (Tschitschérine, 1893), P. (Platysma) planicollis (Tschitschérine, 1899), P. (Plectes) drescheri (Fischer von Waldheim, 1817), P. (Petrophilus) magus magus (Mannerheim, 1825), Pseudotaphoxenus planicollis (Gebler, 1833), Agonum (Olisares) viduum (Panzer, 1796), Mnuphorus sellatus (Gebler, 1843), Cymindis (Arrhostus) andreae Ménétriés, 1832, C. (Menas) miliaris (Fabricius, 1801), C. (Neomenas) antonowi Semenov, 1891, Lebia (Lamprias) festiva festiva Faldermann, 1836, L. (s. str.) trimaculata (Villers, 1789), Brachinus (s. str.) crepitans (Linnaeus, 1758) and B. (Cnecostolus) cruciatus (Quensel, 1806). Two species are recorded for the first time from Xinjiang: Nebria (Eunebria) przewalskii przewalskii Semenov, 1889 and Lebia (Lamprias) punctata Gebler, 1843. Exact distributional data in China are given for the two species: Scarites (s. str.) salinus Dejean, 1825 and Polistichus connexus (Geoffroy, 1758).

The genetic diversity of two native Siberian and two invasive European populations of the Asian ladybird Harmonia axyridis was studied under laboratory conditions. Analysis of the population genetic structure revealed a high degree of isolation of the monomorphic population from Sochi, monomorphism of the population from Serbia, and high genetic heterogeneity of the populations from Novosibirsk and Altai. The allelic profile data showed that the Novosibirsk population contained the greatest number of alleles. Our preliminary results indicate high genetic homogeneity of the Sochi population, which is consistent with the initial stage of expansion and contradicts the hypothesis of its hybrid origin.

In the Balashikha Urban District of Moscow Province, a ladybird, Clitostethus arcuatus (Rossi), predator of the cabbage whitefly (= celandine whitefly) Aleyrodes proletella (L.), was collected in May 2019 on celandine, Chelidonium majus L., in a coniferous forest. This southern Palaearctic ladybird had been previously known from natural habitats in Russia only in the Northwestern Caucasus.

Two new subgenera of the genus Otiorhynchus Germar, 1822 are described: Prohanibotus Savitsky, subgen. n. (the type species: O. auripes Stierlin, 1875) and Parahanibotus Savitsky, subgen. n. (the type species: O. mazdaranicus Magnano, 2006). New data on the taxonomy and distribution of some little-known species of the subgenera Hanibotus Reitter, 1912 and Parahanibotus subgen. n. are presented.
