  • Results and prospects of the chromosomal study of the main groups of
           economically important Chalcidoidea (Hymenoptera)
    • Abstract: Abstract A brief review of the results of the chromosomal study of the main economically important groups of parasitoids of the superfamily Chalcidoidea is presented. Methods of chromosomal analysis can be used to study the species complexes within taxonomically complicated groups, to identify adult and immature chalcids to species, to identify insects in laboratory stocks and mass-rearing cultures, to study sex ratios of immature stages, and to reveal specific sex-ratio distorters with chromosomal localization. There are reasons to believe that chromosomal analysis will be successfully used in the future for studying not only economically significant chalcids but also other practically important groups of parasitoid Hymenoptera.

  • A new species of spider wasps of the genus Priocnemis Schiødte, 1837
           (Hymenoptera, Pompilidae) from the Russian Far East
    • Abstract: Abstract A new species of spider wasps, Priocnemis (Priocnemis) sugonjaevi Lelej et Loktionov, sp. n., is described from the Khinganskii State Nature Reserve (Amurskaya Province, the Russian Far East). The new species belongs to the P. unicolor species-group but can be easily differentiated from the East Palaearctic P. (P.) unicolor (Gussa-kowskij, 1926) and P. (P.) ishikawai Lelej, 1992 from Japan (Kyushu) by having a smaller preapical tooth of the claw, long fine setae of the volsella, and a straight apical border of the hypopygium. Priocnemis sugonjaevi Lelej et Loktionov, sp. n. differs from P. (P.) unicolor in a smaller metapostnotum to metanotum length ratio (0.95 vs. 1.1–1.2).

  • Ecological and biocenotic regularities of the spatial distribution of
           phytophages and entomophages in agroecosystems as the basis of
           non-pesticide protection of winter wheat against pests:
           Agro-biotechnological techniques for organic farming
    • Abstract: Abstract Spatial and temporal distributions of the densities of phytophages and their enemies in cereal agrobiocenoses were studied at the biocenotic level. Foci of increased pest densities were revealed. The total injury to the crops was estimated, specifying the role of each pest species in crop loss. Phytosanitary agro-ecological and agrobiotechnological prevention and control measures are proposed that minimize crop loss and ensure high quality of food crops without toxic effect on the environment.

  • Farm testing of non-insecticidal control of soybean and stevia pests in
           Krasnodar Territory
    • Abstract: Abstract A technology of non-insecticidal control of soybean and stevia pests was farm-tested for the first time in Krasnodar Territory. It effectively obviated the need for insecticide treatments in an unfavorable phytosanitary situation, whereas under favorable phytosanitary conditions, both insecticide treatments and means of active biological control could be cancelled. The soybean yield-capacity was 3.29–4.10 t/ha, which was 1.7–2.2 times the average yield-capacity for Krasnodar Territory in 2012–2014. The use of this technology in stevia plantations allowed the farmers to produce clean pharmacological raw materials with no deterioration of their quantity and quality while omitting the use of insecticides. Non-insecticidal control of soybean and stevia pests required only 0.023–0.526 of the usual costs of insecticidal protection and allowed the farmers: (a) to increase the profitability of production of organic foods and raw materials; (b) to improve the phytosanitary situation in agroecosystems and landscapes; (c) to create conditions for preservation, reproduction, accumulation and amplification of the beneficial activities of entomophages.

  • Temporal dynamics of host-landing rate in mosquitoes attacking the
           imitation of a host
    • Abstract: Abstract The rates of mosquito landing on a host-imitating device were measured. The device contained an electric heater to imitate the presence of a warm-blooded animal, a gauze screen impregnated with meat juice, a microphone with an amplifier to record the sounds of mosquito landings and take-offs, and a light meter to record the ambient illumination. In addition, the behavior of mosquitoes near the device was studied by video recording. All the experiments were conducted in the first half of June in evening and morning hours in mixed spruce-birch forests of Moscow region. Audio recordings were digitally analyzed to estimate the landing rates. Significant (more than 50% of the average) quasi-periodic fluctuations of the mosquito landing rate were revealed. The peaks of mosquito activity alternated with drops with an average period of 30 min (20–50 min in different recording sessions). These fluctuations were recorded in calm weather during a gradual change in illumination. Experiments with two similar devices positioned 20 m apart showed that fluctuations of mosquito activity developed independently at each site. The fluctuations in the mosquito landing rate seem to be largely determined by endogenous factors: mosquito females, failing to obtain blood from the host-imitating device, lost interest in it and landed to rest on the nearby vegetation. After 20–50 min, the memory trace of the previous experience gradually faded, and mosquitoes returned to the attracting device thus starting the next peak of activity.

  • Spider (Arachnida, Aranei) assemblages of some habitats from the Kola Gulf
           coast: Phenological aspect
    • Abstract: Abstract Spiders were collected by pitfall traps in three habitats at the Kola Gulf west coast (Murmansk Province) during the snowless period of 2010. A total of 88 spider species were found, 8 of which were new for the Kola Peninsula. The assemblages of the birch forest and the road embankment were the most similar in their species composition but different in the sets of dominant species and the seasonal dominance structure; the assemblage of the maritime meadow was distinguished by the highest capture rates. The species number and abundance of spiders in the assemblages decreased from spring to autumn; the species evenness also decreased while the fraction of the dominants (especially some of them) increased. The most abundant species in all the habitats studied were found to have different periods of maximum activity.

  • Chrysidid wasps (Hymenoptera, Chrysididae)—Parasites of eumenine
           wasps (Hymenoptera, Vespidae: Eumeninae) in Crimea
    • Abstract: Abstract Chrysidid wasps can be considered the most abundant and sometimes the most important enemies of eumenine wasps. We investigated the nesting biology of 36 species of Eumeninae in Crimea (47% of the Crimean fauna) in 2002–2013. As a result we found 15 species of chrysidid wasps (Chrysis cylindrica, Ch. rutilans, Ch. splendidula, Ch. graelsii, Ch. valesiana, Ch. brevitarsis, Ch. ignita, Ch. impressa, Ch. longula, Ch. pseudobrevitarsis, Ch. ruddii, Ch. sexdentata, Ch. ambigua, Ch. taczanovskii, and Stilbum calens) associated with 16 species of hosts of the subfamily Eumeninae. Thus, 13 new host-parasite associations were discovered and 8 previously known ones were confirmed by direct rearing of chrysidids from the nests of eumenine wasps. The data on the host of Chrysis ambigua were obtained for the first time, and the species itself was recorded for Eastern Europe for the first time. Most of the revealed chrysidid wasps develop as inquilines in the nests of eumenines. The reports by early authors of bees as hosts of these chrysidid species are disputable. At least one of the species reared, Stilbum calens, developed as an orthoparasite in the nests of eumenine wasps.

  • Photothermal control of larval diapause in the blowfly, Calliphora vicina
    • Abstract: Abstract Photothermal control of the rate of development and of larval diapause in the arctic population of Calliphora vicina from the Lofoten Islands (Northern Norway) was studied under the laboratory conditions. In the temperature range from 8 to 23°C, the rate of development of the studied population from egg to puparium can be well (r = 0.95) approximated by linear regression. The sum of effective temperatures was about 160 degree-days with the lower development threshold of 4.5 ± 0.6°C. The maternal photoperiodic response induced the larval diapause in a significant fraction of individuals only when larvae developed at temperatures of 4–10°C; relatively high proportion of diapausing larvae was recorded even in the progeny of females that were kept under long day conditions. The intensity of the larval diapause was very variable, which was manifested in the separation of diapausing larvae into two fractions differing in the time of pupariation during both spontaneous and induced reactivation.
