  • Classification of gall midges of the supertribe Brachineuridi (Diptera,
           Cecidomyiidae: Lasiopterinae) with description of new genera and new
           species from the Kurile Islands
    • Abstract: Abstract A new classification is proposed for the gall-midge supertribe Brachineuridi including 4 tribes, 9 subtribes, 24 genera, and 156 species: Brachineurini (Brachineurina, 4 genera, 23 species; Epimyiina, 4 genera, 9 species); Undoneurini trib. n. (Undoneurina subtrib. n., 5 genera, 8 species; Coccidomyiina subtrib. n., 2 genera, 8 species); Rhizomyiini stat. n. (Rhizomyiina, 4 genera, 33 species; Stellaserenina subtrib. n., 3 genera, 3 species); Ledomyiini (Ledomyiina, 8 genera, 61 species; Acinacistylina subtrib. n., 2 genera, 5 species; Kovaleviolina subtrib. n., 2 genera, 3 species), and also 2 genera Palaeospaniocera Meunier, 1901 (1 species) and Ledomyiella Meunier, 1904 (4) with an unclear systematic position. One new tribe, 5 subtribes, 3 genera, and 7 species (Stellaserena vaga gen. et sp. n., Stelladiurna flustra gen. et sp. n., Kuriloneura multifida gen. et sp. n., K. trifida sp. n., Cornistyla tufa sp. n., Rhizomyia flammula sp. n., Acinacistyla sundukovi sp. n.) are described. Keys to the tribes, subtribes, genera, and species of Brachineuridi are given. The genera Ramineura stat. n. and Cornistyla stat. n. are promoted from subgenera of Brachineura. A new synonymy is established: the genus Pararhizomyia Mamaev, 1998, stat. n. (= Effusomyia Fedotova, 2004, syn. n.). New combinations are formed: Ramineura ussurica (Fedotova, 2004), comb. n. (Brachineura), R. musiva (Fedotova et Sidorenko, 2006a), comb. n. (Brachineura), R. subulata (Fedotova et Sidorenko), comb. n. (Brachineura), and R. alia (Mamaev, 1994), comb. n.

  • The nonperiodic population wave: a case study of the larch casebearer
           Protocryptis sibiricella (Lepidoptera, Coleophoridae)
    • Abstract: Abstract Biogeocenotic mechanisms of formation, existence, and extinction of sustained outbreaks of the larch casebearer Protocryptis sibiricella (Flkv.) were investigated from 1995 to 1998 in a forest-steppe larch forest at the Kuznetsk Alatau piedmont. Variation of the pest abundance within the sustained foci is determined by a complex of factors. The first factor is efficient adaptation of the pest to the condition of the host plant. The trophic behavior of the larch casebearer leads neither to permanent damage nor to a loss of stable resistance of the larch trees to secondary pests. Low flight activity of adults and preference of previously damaged trees for oviposition result in repeated infestation of the same larch stands. The second factor is degradation of pastures, which reduces the local abundance of the parasitoids of the casebearer and thus increases its survival rate. The third factor is the constant heterogeneous condition of the host plant which allows the sustained outbreaks of the phyllophage to exist for a long time. Extinction of sustained outbreaks may be caused by competitive interaction of phyllophagous insects, indirect influence of the host-plant pathogens or extreme abiotic factors.

  • Species diversity and abundance of zoophages as a basic resource of the
           ecological pest management program for suppression of the codling moth
           Cydia pomonella (L.) (Lepidoptera, Tortricidae) and secondary arthropod
           pests in the apple orchard agroecosystems of southern Russia
    • Abstract: Abstract The species diversity and number of zoophagous arthropods as estimated by Margalef’s d index (1958) are the main biological sources of agroecosystem stability. This fact forms the basis of the ecological pest and its enemy management (EPEM) program, which has demonstrated high technical and ecological efficiency, the former referring to the main task of pest control, and the latter, to survival of the natural enemies of the pest and reducing the level of ecological hazard in orchards. Complete and reduced EPEM programs involving five (EPEM-5), four (EPEM-4) and three (EPEM-3) treatments per season with environment friendly synergistic compounds were tested in the ecological and organic apple orchards in the North Caucasus. The results confirm the possibility to protect the orchards by complete (6 treatments) and reduced (4 treatments) versions of EPEM using ecopreparations (bioregulators: Insegar, Match, Dimilin; biopesticides: Fitoverm™, Fermovirin™, Lepidocide™, etc.) to suppress the codling moth and secondary pests while increasing the activity of natural enemies. The EPEM-4 treatment cost in Krasnodar Territory, Northwestern Caucasus is on average half that of the conventional orchard protection measures.

  • On monogyny of the four-eyed fir bark beetle Polygraphus proximus Blandf.
           (Coleoptera, Curculionidae: Scolytinae) and its reproductive behavior
    • Abstract: Abstract The reproductive behavior of the four-eyed fir bark beetle Polygraphus proximus Blandf., an invasive pest of the Siberian fir, was studied. Monogyny of this species was demonstrated in an experiment with colonization of fir logs by groups of adults with a given sex ratio. The female of P. proximus can build several egg galleries and has a mean fecundity of 45 ± 15 eggs. The main elements of intraspecific (reproductive and agonistic) behavior of P. proximus inside the galleries are described in detail. The four-eyed fir bark beetle has some behavioral patterns which are typical of more advanced species of the same genus, such as male entry hole initiation. Comparative analysis of the reproductive behavior and phylogenetic studies of the representatives of the genus Polygraphus Erichson may clarify the functional role of evolutionary transition from monogyny to polygyny in bark beetles.

  • Monitoring and control of Metcalfa pruinosa (Say) (Hemiptera,
           Auchenorrhyncha: Flatidae) in Krasnodar Territory
    • Abstract: Abstract Metcalfa pruinosa (Say) is an invasive planthopper species rapidly expanding its range in Europe and Southern Russia and acquiring new food plants, which makes it a potential threat to agriculture, including organic farming. The distribution and injuriousness of this species in Krasnodar Territory was analyzed, and the possibilities of monitoring and controlling M. pruinosa populations were studied. Yellow sticky traps were found to be unattractive to M. pruinosa. Among the preparations studied, Actara and Fitoverm proved to be the most toxic to the nymphs in the first three days after treatment.

  • The behavioral response of the predatory bug Orius laevigatus Fieber
           (Heteroptera, Anthocoridae) to synthetic volatiles
    • Abstract: Abstract The behavioral response of the predatory bug Orius laevigatus Fieber to synthetic analogues of secondary plant metabolites was studied. Two compounds most attractive to the bug, methyl salicylate and methyl jasmonate, were identified by olfactometer experiments and pot bioassays. The use of natural volatiles or their analogues as attractants for beneficial insects can significantly improve the efficiency of biological pest control methods.

  • The time of origin of the capacity to accrete and mine submerged
           substrates in the midge subfamilies Chironominae Macquart, 1838 and
           Orthocladiinae Lenz, 1921 (Diptera, Chironomidae): Analysis of
           mitochondrial genes COI and COII
    • Abstract: Abstract The nucleotide sequences of the mtDNA cytochrome oxidase I (COI) gene fragment 535 bp long (pos. 100 to 634) in 14 midge species (Diptera, Chironomidae): Dicrotendipes nervosus, Endochironomus albipennis, E. tendens, Glyptotendipes barbipes, G. glaucus, G. gripekoveni, G. imbecillis, G. mancunianus, Polypedilum sordens, Stenochironomus gibbus, Synendotendipes kaluginae, Xenochironomus xenolabus, Xenochironomus sp., Cricotopus glacialis, and those of the mtDNA COII gene fragment 561 bp long (pos. 22 to 583) in 3 midge species: Chironomus plumosus, Chironomus balatonicus, and Baeotendipes noctivaga were determined. The time of gene COI divergence in the phytophilous midges of various taxa was estimated. The wood-mining species Stenochironomus gibbus belongs to the most ancient midges which diverged together with the ancestor form of two subfamilies, Chironominae and Orthocladiinae, about 104 Mya. Phytophily evolved in the midge larvae at different times in different taxa: among Chironominae, about 47.2 Mya in P. sordens, not earlier than 20 Mya in Glyptotendipes, Kiefferulus, and Dicrotendipes, and not earlier than 13 Mya in Endochironomus albipennis; among Orthocladiinae, 19 Mya in Cricotopus. The divergence of the genera containing phytophilous and fouling species, both in Chironominae (Dicrotendipes, Glyptotendipes, Kiefferulus) and Orthocladiinae (Orthocladius and Cricotopus), occurred approximately 20 Mya, and coincided with the beginning of formation of the recent-type limnofaunas 23 Mya.

  • Questions of molecular evolution of pheromone communication in caddisflies
           and lower moths (Insecta: Trichoptera, Lepidoptera)
    • Abstract: Abstract Recent GS-MS and GC-EAD studies of pheromone production and perception in caddisflies and lower moths have shown that these insects use a rather limited selection of volatiles as attractants. Most of them are alcohols and ketones, although the diversity of chemicals produced by sternal glands of abdominal segment V is much wider, especially in the lower Trichoptera. Sternal pheromone glands produce only short-chain polymers in all Amphiesmenoptera. These glands are part of the ground-plan for the related orders, Trichoptera and Lepidoptera, occurring in both sexes and producing similar but not identical sets of components in males and females. The presence of pheromone volatiles is shown to be restricted to the gland segments (Fig. 1), although some other shortchain polymers do occur in the head of females of Molanna angustata (Molannidae). The pheromone blends of lower Trichoptera (Glossosomatidae, Rhyacophilidae, and Philopotamidae) are multi-component and resemble plant volatiles in composition. A hypothesis of the origin of pheromone communication is proposed postulating basic resemblance of early pheromones and plant volatiles in variety and chemical composition. These pheromones were detected by non-specialized receptors of the amphiesmenopteran ancestor and served as guides for insect aggregation on plants as well as on shores of reservoirs, marking the places suitable for a wide variety of species. The primary aggregation function of pheromones was changed in more advanced communication systems to the species-specific signaling with sex-related asymmetry of signals, although the aggregation significance persisted in some species. Pheromone communication has disappeared in some most advanced lineages (e.g., Leptoceridae) with parallel reduction of glands, secretion, and antennal receptors. The pheromone composition does not show gradual divergent evolution in related species; instead, abrupt transformation of pheromone blends with persistence of major components in remote families seems to be the typical case.

  • On the temperature tolerance of diapausing prepupae of the beet webworm
           Loxostege sticticalis L. (Lepidoptera, Pyraloidea: Crambidae)
    • Abstract: Abstract The beet webworm, Loxostege sticticalis L. is a very dangerous polyphagous insect pest. The beet webworm overwinters at the pronymphal stage. In some individuals, the diapause can last from the first generation to the next spring. The influence of 30-days-long exposure at temperatures of +5, +10, +15, +20, and +25°C on survival and subsequent reactivation of diapausing pronymphs of L. sticticalis has been investigated in laboratory conditions. The beet webworm was shown to be very thermotolerant: although the temperature of +5°C, as expected, was optimal for reactivation, the other thermal regimes did not cause a significant decrease in survival and in the proportion of individuals reactivated before the end of the experiment (in 120 days). These data suggest that the southern boundary of the geographical range of L. sticticalis is determined not by high winter temperatures, but rather by some other factors (possibly, by high summer temperatures).

  • Development and harmfulness of Tychius quinquepunctatus L. (Coleoptera,
           Curculionidae) in pea crops in the southeast of the Central Chernozem
           Region
    • Abstract: Abstract The biology, phenology, and harmfulness of the weevil Tychius quinquepunctatus L. in pea crops were studied for many years in the southeast of the Central Chernozem Region. The species showed a highly uneven distribution in Kamennaya Steppe, with preference for the early and short-stemmed pea varieties. A high pest density focus was found with heavy damage to the pea plants in the marginal field zone where 20–30% of the seeds were damaged; the yield loss may be as high as 6%. In later pea crops, T. quinquepunctatus appears at earlier phases of the plant development, oviposition and larval development proceed at higher rates, the damage to the crops increases, and the necessity of control measures against the weevil grows. Effective protection from T. quinquepunctatus in the crops with optimum sowing time may be achieved with a many-target insecticidal treatment at the budding phase.

  • New data on the larvae of the weevil genus Larinus Dejean, 1821
           (Coleoptera, Curculionidae) from northeastern Turkey
    • Abstract: Abstract Larvae of Larinus fucatus Faust, 1891, L. capsulatus Gültekin, 2008, and Larinus sp. aff. leuzeae Fabre, 1870 are described for the first time. The larvae differ in the pattern on the head capsule, in the shape of the endocarinal line, and in the chaetotaxy of the epicranium, frons, and segments of the body, as well as in the presence or absence of stemmata. A key to larvae of 11 Larinus species is provided.
