Aquatic Heteroptera of streams and springs of Ukrainian Steppe zone: species composition, seasonal changes in abundance and biomass.  Grandova.  M. A. Twenty-two species of water bugs from 8 families were found to occur in springs and creeks of south Ukraine. Velia saulii was found in the steppe zone of Ukraine for the first time. The most rich in species composition were limnocrenes (15), less species were found in streams (11) and rheocrenes (9), helocrenes were populated very poorly (1).Species composition of rheocrenes remains almost unchanged during the year. In limnocrenes quantitative characteristics depend on the area and time of existence, the species composition of intermittent limnocrenes in spring and autumn can be markedly different. Seasonal changes in species composition, abundance and biomass in streams are similar to those for small intermittent rivers.

The species structure and peculiarities of distribution of predatory phytoseiid mites (Parasitiformes, Phytoseiidae) on park plants of Kyiv city.  Kolodochka L.O., Grabovska S.L. Fifteen species of nine genera of phytoseiid mites were found. The structure of species complexes of predatory phytoseiid mites and their distribution in plant associations in parks of Kyiv city (Ukraine) are researched. Euseius finlandicus is a dominant in mite species complexes. Kampimodromus aberrans and Typhloctonus aceri are subdominants, and T. tiliarum is subdominant of the first order. All another species come into accidental members of species complexes. Two stenoecic species of predaceous phytoseiid mites, Typhlodromus laurae and Galendromus longipilus, have shown a most high level of selectivity concerning a kind of a plant by search of places of a settlement. Phytoseiid mites Amblyseius andersoni, A. rademacheri, A. reductus, Dubininellus echinus, D. juvenis, Typhlodromus cotoneastri, Paraseiulus soleiger, Anthoseius pirianykae form an euryoecic species group. All of these species have high positive biotopic fidelity index for all investigated plants. Two species, T. aceri and T. tiliarum, have as positive as negative indexes of biotopic fidelity but mostly populate only some definite tree species for permanent habitation.

К. В. Мартынова. Особенности биологии Chrysura laevigata (Abeille, 1879) (Hymenoptera, Chrysididae) в степной зоне Восточной Украины ................. 51

The biological features of Chrysura laevigata (Abeille, 1879) (Hymenoptera, Chrysididae) at the steppe zone of Eastern Ukraine. Martynova K.V. The results of using the method of artificial trap-nests on the territory of reserve “Kam’yani mohyly” (department of Ukrainian Steppe Reserve) in 2008–2010 are presented. For the first time the chrysisid wasp Chrysura laevigata was shown to be the host of megachilid bee Osmia coerulescens and the sex ratio of the former was shown to be 2:1 (133♀: 66 ♂). The role of Ch. laevigata in the regulation of host’s abundance is detected – it is the main enemy of O. coerulescens. The regularity of occupation of the host nests and the biotopical preference within the reserve are also discussed: the highest abundance of the bee and its enemy is registered at the mesophytic biotops, where the chrysidid wasps invade approximately the half of host nests. Both Ch. laevigata and O. coerulescens were shown to overwinter as imagoes (enclosed in their cocoons). One more enemy, the inquiline Sapyga quinquepunctata L. (Sapygidae), was revealed in the nests of O. coerulescens – occupied 10% of host nests, and the half of them it shared with Ch. laevigata. The both enemies had been developing successfully, while following different strategies: the inquiline S. quinquepunctata fed on pollen mass, the methaparasite Ch. laevigata, obviously, ate the last instar larva/prepupae of host bee. The main reason to state the latter is the fact that all cocoons of chrysidid wasp were found within the cocoons of the host bee (the «hidden cocoons»). The investigation on cocoons structure gave also the opportunity to reveal some aspects of interaction between Ch. laevigata and O. coerulescens at the preimaginal stages.

New approaches to monitoring of condition for insect populations in ecosystems Zlotin A.Z., Markina T.Yu., Isichenko N.V. On the base of the rule of dependence of intensity of insects’ taxes on the level of their vitality, the method was suggested for determination the ratio of groups of individuals with different vitality. Successive selection of caterpillars by intensity of trophotaxis immediately after hatching of the main part of population is in the base of this method. Experiments were carried out with two phytophagous species with conditionally different life strategy: k-strategy (Bombyx mori L.) and r-strategy (Lymantria dispar L.). Investigations show the presence of groups of individuals with high, medium and low vitality in population. Study of dynamics of ratio of these groups in successive generations provides insight into tendencies of population dynamics. Obtained data can be used for prediction of population dynamics of pests in plant protection, for valuable insects’ rearing as well as for conservation of natural populations of rare and endangered insect species.

Key words: monitoring, vitality, abundance, prediction, trophotaxis, silkworm Bombyx mori, gypsy moth Lymantria dispar.

Morphological anomalies in Molytinae weevils (Coleoptera, Curculionidae). Nazarenko V. Yu. Two cases of morphological anomalies (teratoses) of Molytinae weevils were found on two Dnieper islands in Kiev in 2006 and 2011: uncomplete schistomely (bifurcation) of left tibia in Pissodes validirostris (Sahlberg, 1834) and unilateral symphysocery of last 6 right flagellomeres in Minyops costalis Gyllenhal, 1834. In male of P. validirostris left tibia bears the short appendage near the middle of its inner side armed with apical black wide spines and resembling additional reduced tibia. No traces of mucro, uncus or tarsus were observed on this appendage. Additional appendages on the tibiae were noted in Sciaphilus asperatus (Bonsdorff, 1785) (Read, 1994). In P. validirostris this case is described for the first time. In female of M. costalis last 6 funicular segments are deformed, shortened and fused on their outer side, so that right funicle is shorter than left and resembles antennae of lamellate or serrate types or large segmented club. Similar aberrations in the structure of antennae are well-known in other beetles: Silpha carinata Herbst, 1783 (Coleoptera, Silphidae) (Prisnyi, 2009) and several species of rove beetles (Staphylinidae), especially in Agrodes elegans Nordmann, 1837, as well as in representatives of families Carabidae, Cerambycidae, Scarabaeidae (Asiain, Márquez, 2009). Complete or partial symphysoceries are known in weevils (Cmoluch, 1965; Nazarenko, 2006), but in M. costalis it is detected first time. Similarity of partial fusion of antennal segments in representatives of different families of Coleoptera, as well as the fact that such a structure of the antennae of some insects is a normal feature, suggests that at least in some cases the nature of these abnormalities may be common to them, probably genetic.

Key words: anomalies, bifurcation, schistomely, symphysocery, teratoses, Coleoptera, Curculionidae, Molytinae, Minyops costalis, Pissodes validirostris.

Species composition of aphid parasites (Hymenoptera: Aphidiidae) of Central Wood-and-Steppe region of Ukraine. O. G Zubenko. As a result of material collection in 2010–2013 on the territory of Central Wood-and-Steppe of Ukraine 29 aphidiid species (Hymenoptera: Aphidiidae) from 9 genera were found. In investigated region Aphidius megourae Starэ, A. phalangomyzi Starэ, Praon necans Масkauer, Trioxys tanaceticola Starэ are recorded for the first time. Among identified aphidiids the largest number of species belongs to the genus Aphidius (13 species); genus Lysiphlebus is represented by 5 species; Binodoxys and Praon – by 3 species each, genera Adialytus, Diaeretiella, Ephedrus, Lipolexis, Trioxys – by one species each. Many aphidiids have habitat preferences, which are mainly determined by trophic specialization of hosts. Species of Adialytus, Lysiphlebus, Lipolexis, Diaeretiella most frequently infest aphids on herbaceous plants, meadows and fields; some species of Praon and Ephedrus are parasites of aphids on aquatic and semiaquatic plants. Among the identified species of primary parasites, 7 species are found to be most effective: Aphidius absinthii, A. funebris, A. ervi, Lysiphlebus confusus, L. cardui, L. fabarum, Praon volucre.

To species composition of predatory phytoseiid mites (Parasitiformes: Phytoseiidae) in plant associations of Lugansk area (Ukraine). L. A. Kolodochka, V. Yu. Bondarev Species composition of predatory phytoseiid mites (Parasitiformes: Phytoseiidae) in plant associations of Lugansk area (Ukraine) were investigated at the first time. 33 species of 12 genera of the family are detected. Frequency of occurrence and fidelity to different types of plant communities for each species of mites were determined. Detected phytoseiid mites may be conditionally divided on three groups – inhabitants of herbal plants (6 species, namely, Amblyseius herbarius, A. nemorivagus, Amblyseiulus okanagensis, Neoseiulus agrestis, N. bicaudus, N. marginatus), inhabitants of woody and shrubby plants (10 species – Typhlodromus rodovae found exclusively on coniferous plant races, as well as Neoseiulus astutus, N. danilevskyi, Amblyseiella antonii, Typhloctonus tiliarum, Paraseiulus incognitus, P. intermixtus, P. soleiger, Amblydromella (s. str.) caudiglans, Amblydromella (Aphanoseia) verrucosa, which were found on foliaceous breeds practically), while the rest 18 species which did not give preference for particular plant type were placed in third groop. Mites Amblydromella (s. str.) pirianykae and Am. (s. str.) recki must be named as the most numerous and widespread species on investigated territory. They were found on 60 and 62 plant species correspondingly and in sum approximately into 50% of samples. Mites Amblyseiella antonii, Amblyseius nemorivagus, Amblyseiulus okanagensis, Neoseiulus agrestis looked as the most rare mites (only 1 exemplar of each species were found on investigated territory).

Features of ontogeny of darkling beetle Prosodes obtusa (Fabricius, 1798) (Coleoptera, Tenebrionidae). Cherney L.S., Nitochko M.I. Over one generation of P. obtusa (Fabricius, 1798) at least 4 groups of larvae of this species with differing morphology were found in the nature. In this regard, existing identification keys for larvae of darkling beetles (Key ..., 1964, Cherney, 2005, Cherney, Fedorenko, 2006 and others.) are considered as not suitable for the identification of its young larvae, since they are based only on the  characters of individuals of the last larval stage. The identification keys for Prosodes Eschscholtz, 1829, including the species P. obtusa, were added and modified on the basis of the analysis of age-related changes of morphological structures of larvae of P. obtusa. The life cycle of P. obtusa and the morphology of its egg and pupa were described at the first time. It is established that the number of trichogenal cells functioning during molting period of larvae and the number of functioning groups of hypodermal cells is not constant for each of its age; during molting period of larvae, trichogenic hypodermal cells are functioning simultaneously with peeling of exuviae, which form a new body hair covering; and the groups of epidermal cells are functioning later that form spikes. It is proved that the larvae of P. obtusa are saprophagous. The factors causing the decline of the population of the species were revealed.

Nosema ceranae Fries et al., 1996 (Microspora, Nosematidae) – a honey bee parasite in Ukraine. Yefimenko Т. М., Odnosum H. V., Tokarev Y. S., Ignatieva А. N. For the first time on apiaries of Ukraine in three regions (Kiev, Poltava and Zaporozhya) was found a Microsporidia Nosema ceranae (Microspora, Nosematidae) - the pathogen of so-called «Asian» Nosematosis, which is considered to be the one of the causes of mass death of bee families. Clinical signs and course of the Nosematosis in bee families where was found Microsporidia N. ceranae, were classical, namely weak development of families in the spring, in some families - the presence of traces of diarrhea. The attention is focused on the necessity to continue research directed on studying of the spread of Microsporidia N. ceranae on apiaries of Ukraine and its harmfulness for the beekeeping industry in mono and mixed parasitism along with Microsporidia N. apis.
