  • Summer Diapause as a Special Seasonal Adaptation in Insects: Diversity of
           Forms, Control Mechanisms, and Ecological Importance
    • Authors: A. Kh. Saulich; D. L. Musolin
      Pages: 1183 - 1212
      Abstract: Insects living in the temperate climate include summer diapause, or aestivation, in their seasonal cycle to solve various problems related to adaptation to unfavorable seasons. Unlike winter diapause, summer diapause occurs in summer and is usually terminated in autumn when active feeding, development, and/or reproduction are restored. Typically, high temperature and long day induce summer diapause and then maintain it, whereas short day and low temperature prevent induction of this diapause or terminate it. The summer diapause syndrome is basically similar to that of winter diapause; it includes prior development of large fat body, decreased level of metabolism, increased general resistance to unfavorable abiotic and biotic conditions, etc. Inhibition of morphogenesis and gametogenesis is under the control of the endocrine system. The onset of summer diapause is often accompanied by migrations to varying, sometimes significant distances to the sites of aestivation. The selective factors responsible for evolution of summer diapause vary between insect species. Climatic factors and, consequently, availability and abundance of food, as well as pressure of predators and parasites are likely to be the main factors that stimulate its occurrence. In some species, prolonged diapause begins in spring or early summer and ceases only after over-wintering. When studied in detail, such prolonged diapause often turns out to be a sequence of two independent diapauses, summer and winter ones, occurring in succession without detectable external changes.

  • Dynamics of the Photo-Trophic Termination of Reproductive Diapause in
           Females of the Multicolored Asian Ladybird Harmonia axyridis (Pallas)
           (Coleoptera, Coccinellidae)
    • Authors: A. N. Ovchinnikov; S. Ya. Reznik; A. A. Ovchinnikova
      Pages: 1213 - 1218
      Abstract: Females of certain aphidophagous ladybirds in the absence of natural protein food (aphids) enter reproductive diapause. Reactivation of diapausing beetles is possible only after consuming the food which is suitable for oogenesis of females and development of larvae. The influence of diet and photoperiod on the dynamics of weight and on the rate of reproductive maturation of reactivating females of Harmonia axyridis was studied under laboratory conditions. The experiments were conducted at combinations of two day lengths (12 and 18 h) with 6 trophic regimes with the following mean numbers of daily consumed aphids: 0 (aphids were absent over the whole experiment), 0.1 (1 aphid was provided every 10 days), 0.5 (1 aphid every second day), 1 (1 aphid every day), 10 (10 aphids every day), and 50 (about 50 aphids every day). Judging from the state of ovarian development estimated by dissection 20 days after the beginning of the experiment, the threshold of the trophic termination of reproductive diapause under the long day conditions lies between the regimes of 0.1 and 0.5 aphids per day, which is approximately equal to the earlier investigated threshold of the trophic induction of diapause. Short day slowed reactivation and has increased the threshold of the trophic response up to 1-10 aphids per day. Based on these data, we conclude that under natural conditions females which entered reproductive diapause because of the absence of aphids are capable of reactivation in the presence of even a minimal amount of natural protein food. Moreover, in spring and summer (when the probability of the increase in aphid abundance is relatively high) reactivation starts at lower prey population density than in autumn, when the appearance of the stable aphid colony (which is necessary to complete the development of the emerged larvae) is less probable.

  • Adaptation of Introduced Entomophages in the Insectarium of the
           Polar-Alpine Botanical Garden
    • Authors: N. S. Rak; S. V. Litvinova
      Pages: 1219 - 1226
      Abstract: As the result of a many-year experiment on adaptation of introduced entomophages in the specialized insectarium of the Polar-Alpine Botanical Garden (PABGI), populations of the following species have been established: Phytoseiulus persimilis Ath.-Henr., Amblyseius mckenziei Schuster et Pritchard, Aphidius matricariae Hal., Aphidius colemani Vier., Encarsia formosa Gahan, and Aphidoletes aphidimyza Rond. These populations have short periods of preimaginal development, are resistant to sharp temperature changes, very voracious and active. These acari- and entomophages can persist for a long time under the specific conditions of the greenhouse ecosystem, effectively control pests, and regulate the biocoenotic complex at the level meeting the phytosanitary requirements. In their ecological characteristics the PABGI cultures surpass the conspecific populations from more southern areas.

  • Reproductive Behavior of the Bug Molipteryx fuliginosa Uhler (Heteroptera,
           Coreidae) in the South of the Russian Far East
    • Authors: T. O. Markova; M. V. Maslov; E. V. Kanyukova; N. V. Repsh
      Pages: 1227 - 1233
      Abstract: Reproductive behavior of Molipteryx fuliginosa (Uhler) was investigated in Primorskii Territory of Russia. From 4 to 18 repeated copulations of one female lasting from 2 to 48 hours were recorded in cages. The behavior of ovipositing females and the stages of oviposition are described for the first time. The number of eggs laid between copulations varied from 1 to 13, the number of oviposition acts, from 4 to 11, and the total female fecundity, from 21 to 38 eggs. Caged females laid eggs on plants and also on dead substrates unsuitable for nymphal feeding, such as cloth, dry branches, and a wooden pole. Copulation of M. fuliginosa was also observed under natural conditions. The preferred mating places of M. fuliginosa in anthropogenically modified habitats and in small-leaved riparian forests were plants of Rubus idaeus L., R. caesius L., and Rubus sp. After mating, females migrated in search of places for oviposition. Single eggs were found on the following plants not known previously as hosts of this bug: Solanum lycopersicum L., Carex sp., Elytrigia repens (L.) Nevski, and Taraxacum officinale Wigg. The females seemed to lack selectivity in the choice of place for oviposition, which was not always associated with host plants, despite their abundance and availability.

  • The Effect of Climatic Factors on the Activity of Ants (Hymenoptera,
           Formicidae) in Broadleaf Forests of Kiev. Communication 2
    • Authors: S. V. Stukalyuk
      Pages: 1234 - 1243
      Abstract: Studies of seasonal dynamics of the activity of ants were carried out in July–August of 2013–2015 in broadleaf forests (Kyiv, Ukraine. Transects were located within foraging areas of three dominant species Formica rufa L., Lasius fuliginosus (Latreille), and L. emarginatus (Olivier). Thirteen species of ants were encountered on the soil surface. Factors that influence the activity of ants in forests may be ranked by importance as follows. (1) Climatic factors: (a) air temperature and soil humidity; (b) mean monthly rainfall; (c) air humidity. (2) Phytogenic factor (tree species composition). 3. Interspecific hierarchy of ants (primarily, territoriality of the dominant species).

  • Musculature of the Ovipositor of Timia erythrocephala Wiedemann, 1824
           (Diptera, Ulidiidae)
    • Authors: O. G. Ovtshinnikova; A. N. Ovchinnikov
      Pages: 1244 - 1248
      Abstract: The structure of the ovipositor sclerites and musculature was investigated in Timia erythrocephala Wiedemann, 1824 (Ulidiidae), whose larvae are saprophagous. The ovipositor musculature of this species is compared with that of the previously investigated Tephritidae. Based on morphological analysis, characters common to Ulidiidae and primitive Tephritidae and supposedly plesiomorphic for Tephritidae are revealed. Abdominal segment VII in Timia is compact and consists of tergite and stemite VII fused into a syntergostemite with a visible suture. The preserved suture between the stemite and tergite of segment VII should be regarded as an intermediate state in the process of syntergostemite formation in tephritoid flies, which was completed already in Lenitovena.

    • Authors: E. P. Nartshuk; A. A. Przhiboro
      Pages: 1285 - 1306
      Abstract: The fauna of grass flies (Diptera: Chloropidae) of the Crimean Peninsula is reviewed for the first time. The study is based on examination of the collection of the Zoological Institute, Russian Academy of Sciences (St. Petersburg), which includes the material collected in Crimea by the authors, the collections of the Zoological Museum of the M. V. Lomonosov Moscow State University and V. I. Vernadsky Crimean Federal University (Simferopol). The annotated list includes 92 species in 34 genera and three subfamilies. Most of the species (61) are recorded from Crimea for the first time. Six species, Chlorops horridus Becker, Ch. puncticornis Loew, Dicraeus (Oedesiella) beschovskii Nartshuk, Lasiosina chandleri Ismay, Meromyza meigeni Nartshuk and Oscinimorpha longirostris (Loew) are recorded for the first time from Russia and Eastern Europe. The characters for distinguishing Oscinimorpha arcuata Duda from O. longirostris (Loew), i.e., the structure of head and the male genitalia, are provided. The boreo-montane species Oscinella vastator (Curtis) and Meromyza curvinervis (Zetterstedt) are found on the Chatyrdag Mountain and Yaila (mostly forestless plateau in the Crimean Mountains). Species with southern European, Mediterranean and Macaronesian-Mediterranean ranges were recorded mostly on the South Coast of Crimea. The Crimean fauna of Chloropidae is compared with the faunas of Sardinia and Turkey.

  • The Origin of the Northern Palaearctic Fauna of Bloodsucking Insects, by
           the Example of Fleas (Siphonaptera), Mosquitoes (Diptera: Culicidae), and
           Blackflies (Diptera: Simuliidae)
    • Authors: S. G. Medvedev; A. V. Khalin; S. V. Aibulatov
      Pages: 1307 - 1320
      Abstract: The territory of Fennoscandia and northwestern European Russia was released from the glacier cover in the Upper Pleistocene and has been recolonized by bloodsucking insects during the last 11 thousand years. The sources of formation of the Northern Palaearctic fauna of such groups of bloodsucking insects as fleas (Siphonaptera), mosquitoes (Culicidae), and blackflies (Simuliidae) were different in the postglacial period. One of the sources was the fauna of the ancient Mediterranean and southern Europe, while others were the faunas of northeastern China and Primorye. In turn, the two latter sources are closely related to the ancient faunal centers of the East Asian Subregion of the Palaearctic and also of the Indomalayan Region. Besides, some species and genera have spread from the West American Subregion of the Nearctic through Beringia.

           Formicidae: Dolichoderinae) of Mexico
    • Authors: D. A. Dubovikoff; J. M. Coronado-Bianco
      Pages: 1321 - 1331
      Abstract: Mexican ants of the genus Dolichoderus are revised. Five species of the genus are recorded: D. bispinosus (Olivier, 1792), D. diversus Emery, 1894, D. lutosus (Smith, 1858), D. mariae Forel, 1885 and D. plagiatus (Mayr, 1870). Dolichoderus tridentanodus Ortega-De Santiago et Vásquez-Bolaños, 2012 is synonymized with Camponotus mucronatus Emery, 1890. Early records of D. germaini Emery, 1894 and D. lugens Emery, 1894 from Mexico are misidentifications and those species are excluded from the list of the Mexican fauna. Dolichoderus mariae Forel, 1885 is newly reported for the fauna of Mexico. Identification key to Mexican Dolichoderus species is given.

  • Eriophyoid Mites (Acariformes, Eriophyoidea) from Rosaceae: Taxonomic
           Diversity, Host-Parasite Relationships, and Ability to Cause Galls
    • Authors: S. I. Sukhareva; A. A. Pautov; I. E. Dodueva; P. E. Chetverikov
      Pages: 1378 - 1390
      Abstract: A review on the complex of species of eriophyoid mites associated with Rosaceae is given, focused on the phylogeny, biology, and distribution of their host plants and galls induced by these mites. About 200 species of 39 genera from 3 families ofEriophyoidea are known from Rosaceae. Among them, 6 species from 2 genera belong to Phytoptidae, 178 species from 27 genera, to Eriophyidae, and 28 species from 10 genera, to Diptilomiopidae; 7 genera of the latter family are represented on Rosaceae by a single species each. The ability to induce galls is discussed using the example of the most widespread and numerous genera of the family Eriophyidae from Rosaceae. Mites of two large subfamilies, Eriophyinae and Phyllocoptinae, include both vagrant and concealed forms. The types of galls caused by mites are related to the systematic position of mites and the distribution of mites and their host plants. The hypothesis of host shifts of eriophyoid mites from other plant families to Rosaceae is considered. Most of the species which presumably switched to Rosaceae have been described from Southeast Asia. Morphological similarity between vagrant and concealed forms from the paraphyletic tribes Eriophyini and Phyllocoptini, and also Aceriini and Anthocoptini is discussed. Their pairwise similarity might be the result of evolution (Eriophyini → Phyllocoptini and Aceriini → Anthocoptini) connected with change oflife style.

  • Local Formation of High Population Density of the Ticks Dermacentor
           reticulatus (Parasitiformes, Ixodidae) in Tomsk
    • Authors: V. N. Romanenko; V. V. Sokolenko; Yu. V. Maximova
      Pages: 1391 - 1396
      Abstract: The meadow tick Dermacentor reticulatus (Fabricius, 1794) was sporadically recorded earlier on the south outskirts of the city of Tomsk. Examination of the Tom River high bank on which trees and shrubs had been removed by a destructive landslide at the end of the XX century and which had since been overgrown with herbaceous vegetation, revealed high abundance of D. reticulatus: 42 ind./km of survey route in September 2015 and 66 ind./km in late April 2016. It is hypothesized that for several consecutive years, most of the larvae and nymphs completed their development within one summer and managed to molt to adults before the autumn drop of temperature, which resulted in such an abrupt increase in the meadow tick density. The rapid preimaginal development was possible due to increased temperatures on the surface of the south-southwest facing slope in the absence of tree canopy.

    • Authors: A. I. Korzeev; A. A. Stekolnikov
      Pages: 1031 - 1047
      Abstract: The morphology of the male terminalia (uncus and subunci) was studied in 39 species of the subtribe Polyommatina (Lycaenidae). Traces of nine established characters were mapped on the molecular phylogeny of the subtribe proposed by Talavera et al. (2013). The ancestral character states for these morphological structures were established in Plebejus s. l. and Polyommatus s. l. According to the time calibration of the proposed molecular tree, the studied skeletal structures (uncus and subunci) evolved very slowly within the last million years. It was shown that the similar shape of the uncus and subuncus branches arose independently and underwent parallel morphological transformations. In particular, wide and, as a rule, ventrally directed uncus lobes arose independently in Polyommatus s. str., Alpherakya, Glabroculus, and Aricia. Yet, in various evolutionary lines of Polyommatina similar changes in the length ratio of the proximal and distal parts of the subunci as well as in the shape of their apical hooks were observed. The character states marking the groups Polyommatus s. str. and Aricia were established. The evolutionary changes in the uncus morphology were highly non-uniform in the various monophyletic lines of Polyommatina. As a result, representatives of some “old” lines have more specialized features of the uncus morphology in comparison with those belonging to “young” lines that retain ancestral character states. In Polyommatina, the transformation of the male terminalia was directed toward development of the most effective mechanism of female fixation during copulation. This goal was reached in similar ways in various evolutionary lines of Polyommatina, which explains numerous parallelisms in morphology of these structures.
