  • A contribution to the fauna of blackflies of the subfamily Prosimuliinae
           (Diptera: Simuliidae) of the Sakha Republic (Yakutia)
    • Abstract: Examination of river basins of Yakutia and the study of the previously collected material revealed 34 species of the subfamily Prosimuliinae belonging to 8 genera (Gymnopais, Prosimulium, Helodon, Stegopterna, Greniera, Cnephia, Metacnephia, and Sulcicnephia). The fauna of Yakutia was supplemented with two species, Cnephia angarensis Rubzov, 1956 and Gymnopais frontatus Yankovsky, 1982. The distribution of 6 species was clarified: Prosimulium tridentatum, Helodon alpestris, H. irkutensis, H. rubicundus, Stegopterna asema, and Cnephia lyra. A combined table of species distribution with GPS coordinates of the collecting sites was compiled.

  • Interspecific variation in photoperiodic effect on the rate of preimaginal
           development in Harmonia axyridis (Pallas) (Coleoptera, Coccinellidae)
    • Abstract: The effects of day length on preimaginal development and reproductive maturation of females of laboratory strains which originated from two native: Irkutsk (Siberia, Russia) and Daegu (South Korea) and two invasive: Sochi (Caucasus, Russia) and Pardubice (Czechia) populations of Harmonia axyridis were investigated under the laboratory conditions. In all the 4 strains, the acceleration of development caused by the short day (all other conditions being equal) was relatively stronger in those larvae that later, at the adult stage, delayed reproductive maturation. This correlation can be considered as an indirect proof that both reactions are based on the common physiological mechanism. However, comparison of the parameters of photoperiodic responses showed that although the photoperiodic effect on reproductive maturation in individuals from Sochi and Pardubice invasive populations was relatively weak, the effect of day length on the rate of their preimaginal development was even somewhat stronger than that of individuals from Irkutsk and Daegu native populations. This uncorrelated interpopulation variation of the quantitative and qualitative photoperiodic responses suggests that in spite of the common physiological mechanism, the responses influencing preimaginal development and reproductive maturation of H. axyridis are to a certain extent independent and thus the evolution of their parameters (in particular, adaptation to new climate conditions) occurs independently.

  • The fauna of free-living mites (Acari) of Greenland
    • Abstract: When compiling The Greenland Entomofauna. An Identification Manual of Insects, Spiders and Their Allies (ed. by J. Böcher and N.P. Kristensen), the mite collections kept at the Zoological Museum of the University of Copenhagen were processed. As a result, illustrated keys and a photo atlas of the genera were prepared. An analysis of the type material preserved in the Museum allowed three taxa of Mesostigmata to be synonymized: Vulgarogamasus immanis (Berlese, 1903) = Parasitus fucicola Trägårdh, 1904 syn. n.; Pneumolaelaps groenlandicus (Trägårdh, 1904) = Hypoaspis (Pneumolaelaps) arctos Karg, 1984 syn. n.; Zercon hammerae Sellnick, 1960 = Z. thulium Athias-Henriot, 1980 syn. n. The number of mite species known in Greenland increased from 158 to 290 (59 species were identified only to the generic level). They belong to the orders Parasitiformes (Mesostigmata 63 species, Ixodida 1) and Acariformes (Prostigmata 94, Endeostigmata 5, Oribatida 110, Astigmata 17). The free-living mite fauna in general is characterized by a complete taxonomic structure and a full range of ecological diversity. The Greenland fauna of oribatid mites mainly consists of widespread polyzonal species (70%) while specialized cryobiont (arctic and arctomontane) species are few (4%); the Nearctic species prevail over the European invaders with a ratio of 1.5: 1. On the contrary, the gamasid mite fauna includes only 25% of widespread species; the cryobiont elements comprise up to 45%; the ratio of the species of Nearctic and Palaearctic origin is 1: 4.

  • On assessment of the large-scale effect of introduction of the ragweed
           leaf beetle Zygogramma suturalis F. (Coleoptera, Chrysomelidae) on the
           phytocenoses of South Russia
    • Abstract: Evaluation of the efficiency of large-scale projects of phytophage introduction for weed control is of importance for both the theory and practice of biological control. Introduction of the ragweed leaf beetle Zygogramma suturalis F. into the USSR in the 1960–80s is an example of such a project. The main theoretical result of this project was the discovery of the phenomenon of the solitary population wave (SPW), which is a necessary condition for successful biological control of the invasive weed. Recent investigations confirm the long-term efficiency of acclimation of the common ragweed phytophages in the South of Russia. The disappearance of a huge phytomass of the common ragweed in the fields, an abrupt drop in the seed density in the soil, reduction of the infestation areas, and absence of large and dense weed patches in satellite images testify to the fact that the goal of phytophage introduction, i.e., suppression of the common ragweed in agrophytocenoses, has been met. The tasks of the next phase of ragweed suppression are discussed in view of the role of the common ragweed as a synanthropic allergic agent and a ruderal plant growing in anthropogenically transformed territories.

  • The response of some main coleopteran pests of grain to a joint action of
           pirimiphos-methyl and bifenthrin
    • Abstract: Mortality of adult beetles of several grain pest species (Sitophilus oryzae L., S. granarius L., Tribolium confusum Duv., Rhizopertha dominica F., and Oryzaephilus surinamensis L.) was studied under the experimental exposure to grain treated with biinsecticide containing pirimiphos-methyl (40%) and bifenthrin (1%). It was concluded that the response of the beetles to the simultaneous presence of both compounds needed to be specially studied before suggesting the use of complex insecticide. A dose of 15 mL of biinsecticide per 1 t of grain appeared to be sufficient for total extermination of the pests in the treated grain within 7 days.

  • Fleas (Siphonaptera) associated with mammals in the mountain area between
           the Kuban and Bolshaya Laba Rivers
    • Abstract: The flea fauna of mammals in the area between the Kuban and Bolshaya Laba Rivers counts 47 species. Most of them parasitize several hosts. The species composition and the structure of flea communities in different altitudinal belts are characterized. The flea Ctenophthalmus wagneri and some other flea species with Ancient Mediterranean ranges show the highest dominance indices in the foothills. Ctenophthalmus proximus and Leptopsylla taschenbergi, possessing ranges of the Caucasian type, prevail in the middle mountain belt. Megabothris turbidus and some other boreal species dominate among the species collected in the high mountain belt.

  • On the distribution dynamics of some beetles (Coleoptera: Coccinellidae,
           Bruchidae, Curculionidae) in the plains of the Northwestern Caucasus,
    • Abstract: At the beginning of the XXI century, several species of the coleopterous families Coccinellidae, Bruchidae and Curculionidae were recorded as new to the Northwestern Caucasus (Krasnodar and Stavropol territories and the Republic of Adygea). Some of them apparently have been unintentionally introduced from the distant (the East Asian bruchid Megabruchidius tonkineus Pic, 1914) or neighboring (the Western Mediterranean weevil Otiorhynchus aurifer Boheman, 1843) regions, while two species of weevils, Sternuchopsis karelini Boheman, 1844 and Orchestes mutabilis Boheman, 1843, may have expanded westward their central or eastern Palaearctic ranges. The weevil, Otiorhynchus ovalipennis Boheman, 1843 has expanded its distribution from the Black Sea coast in Krasnodar Territory northward to the vicinity of Krasnodar in Adygea. The Harlequin lady beetle Harmonia axyridis (Pall.) was for the first time found in the plain part of Anapa and Kavkazskii districts in 2012 and 2013.

  • Musculature of the male genitalia in the tribe Ulidiini (Diptera,
    • Abstract: The musculature of the male genitalia was studied in three species of Ulidiini (Tephritoidea: Ulidiidae): Timia erythrocephala Wiedemann, 1824, Ulidia ruficeps Becker, 1913, and Physiphora alceae (Preyssler, 1791). Previously, the male genital sclerites of this tribe were studied (Galinskaya, 2011a, 2011b, 2012, 2014). The study has shown significant similarity of the set of muscles between the species. Small differences in the sites of muscle insertion on the sclerites do not affect the functions of these muscles. The lateral hypandrial lobes are always asymmetrical in all the species studied, the right lobe being always larger than the left one. This probably results from the postabdomen rotation and may be indirectly related to flight maneuverability during copulation. Clear separation of the attachment sites of the adductor of subepandrial sclerite M3 and the adductor of surstyli M4 is noteworthy. These muscles are synergistic, as in most other representatives of Cyclorrhapha widely varying in the structure of the surstyli and subepandrial sclerite and in the attachment of M3 and M4; their contraction results in the surstyli grasping and holding the female’s abdomen during copulation. Comparative analysis shows that all the studied representatives of Tephritoidea have a similar set of the male genital muscles. The correspondence of homologous muscle designations in different classifications has been analyzed. In particular, the phallapodemic muscle M2 in Ulidiidae is shown to be homologous to muscle MUS2 in Ceratitis capitata (Tephritidae). Thus, the hypandrial origin of the lateral sclerites is confirmed.

  • The position of the family pantophthalmidae in the classification of the
           orthorrhaphous Brachycera (Diptera) based on larval characters
    • Abstract: The larval morphology of Pantophthalmidae, a peculiar family of xylobiont flies distributed in the Neotropical Region, is studied. The larva supposedly belonging to the genus Opetiops End. is described and compared with the known larvae of Pantophthalmus Thunb. In the larval characters, the family is closest to Stratiomyidae and Xylomyidae. Adaptations to habitation inside wood have resulted in the closeness of the larval general appearance to the representatives of Temnostoma Le Pel. et Serv. (Syrphidae).

           disjunction in the Kura-Aras Lowland
    • Abstract: The distributional characteristics of Pimelia cursor Ménétries, 1832 (Tenebrionidae), Araxia mucronata Khnzorian, 1957, A. cristofaroi Gültekin et Borovec, 2008, and Ptochomorphus latiscrobs (Hochhuth, 1847) (Curculionidae: Entiminae: Sciaphilini) are considered. It is shown that the ranges of P. cursor, A. mucronata, and P. latiscrobs have similar disjunction in the Kura-Aras Lowland. A presumable scenario of the origin of this disjunction is discussed.

  • The life cycle and production of three common stonefly species (Insecta,
           Plecoptera) in the Kedrovaya River (the south of Primorskii Territory)
    • Abstract: The life cycles and production parameters of three common detritivorous stonefly species (Paracapnia khorensis, Amphinemura verrucosa, and Taenionema japonicum) from the Kedrovaya River at the Kedrovaya Pad Reserve (the south of Primorskii Territory, Russian Far East) were studied. Judging from the body size histograms, all these species are univoltine and have no winter diapause. Eggs develop directly; larval growth is slow, takes about 282–295 days, and proceeds even at low water temperatures in winter. The P. khorensis population is characterized by synchronous adult emergence and recruitment, as well as by slow continuous increase in larval linear size and body mass from June to March. Amphinemura verrucosa adults have a prolonged flight period from June to August, and their recruitment takes place for two months, till the end of November. Larvae grow during autumn and winter, but the most rapid growth is recorded in spring, when the water temperature rises, just before adult emergence in June and July. The development of T. japonicum is characterized by larval diapause in August and September when the water temperature is high. In October, larval growth is resumed and remains rapid through autumn and winter, up to adult emergence in May. The species studied had similar values of instantaneous growth rate (0.021–0.022 day−1), cohort production efficiency P/Bcohort (6.01–6.55), and annual efficiency of population production P/Bannual (7.78–8.11). More variable throughout the growing period was the mean biomass, and this accounted for the differences in secondary production values which ranged from 13.2 to 130.7 mg dry mass/m2.

           (Lepidoptera, Gracillariidae) in the Middle Volga Area, with a key to the
           species using morphological characters of the female genitalia
    • Abstract: Data on the fauna and bionomics of the leaf blotch miner genus Phyllonorycter Hbn. of the Middle Volga Area are given. Twenty-eight species have been reared from leaf mines on more than 20 species of hosts in the investigated area. The harmful species Phyllonorycter medicaginella (infesting herbaceous legumes), Ph. apparella (the larvae heavily infest poplar leaves), and Ph. issikii are new to the region. Details of the female genitalia of Phyllonorycter are reported, and their characters are used for species diagnostics for the first time. A key to 13 Phyllonorycter species is given, with data on their host plants.
