Krefftascaris (Nematoda, Ascaridoidea) from Australian Side-Necked Turtles with Description of Krefftascaris sharpiloi sp. n. from Chelodina rugosa. Tkach V. V., Kuzmin Yu. I., Snyder S. D. — Previously known records of ascaridoid nematodes Krefftascaris Sprent, 1980 are summarized and new records of the genus reported. Krefftascaris sharpiloi Tkach, Kuzmin et Snyder, sp. n. is described from specimens found in the stomach of the northern snake-necked turtle Chelodina rugosa collected from two localities in Northern Territory, Australia. The new species differs from the only previously known Krefftascaris species, K. parmenteri Sprent, 1980, by the presence of thickened and bifurcated anterior edges of the lateral cuticular alae and a difference in the relative distance from the anterior end to the nerve ring which is 1.5 to 2 times greater in K. parmenteri. Comparison of approximately 2.100 bases of ribosomal DNA sequences This study contains first reports of Krefftascaris in Chelodina rugosa, Chelodina burrungandjii, Chelodina canni and Emydura tanybaraga and the first records of this genus in the Northern Territory, Queensland and Western Australia. Molecular phylogenetic analysis based on sequences of nuclear small ribosomal subunit gene has demonstrated close affinities between Krefftascaris and Heterocheilus, the type genus of the Heterocheilidae and Heterocheilinae. Parasitism of several species and genera of Heterocheilidae in crocodiles allows us to hypothesize that Krefftascaris may have been acquired by turtles from crocodilians.
Key words: Nematoda, Ascaridiidae, Krefftascaris, sp. n., Australia, turtles, Chelodina, Elseya, ribosomal DNA sequences, molecular phylogeny.

Helminth Fauna of Roe Deer (Capreolus capreolus) in Ukraine: Biodiversity and Parasite Community. Kuzmina T. A., Kharchenko V. A., Malega A. M. — The results of survey of helminth species diversity of roe deer (Capreolus capreolus Linnaeus, 1758) from nine regions of Ukraine are presented. Ninety-two roe deer from Chernigivska, Zhytomyrska, Kyivska, Vinnytska, Rivnenska, Ternopilska, Khmelnitska, Sumska and Cherkasska regions were examined by the partial helminthological dissection. Totally 30,753 helminth specimens were collected and identified by morphological criteria. Prevalence of roe deer infection with helminths was 92.4%. Sixteen helminth species (1 of the Class Trematoda, 2 — of Cestoda and 13 — of Nematoda) were found. Setaria cervi (prevalence — 10.9%) was found in visceral cavity. Dictyocaulus eckerti (6.9%) and D. capreolus (2.3%) was found in lungs. Taenia hydatigena larvae (2.3%) were found in mesentery. Paramfistomum cervi (10.9%), Haemonchus contortus (57.6%), Ashworthius sidemi (40.2%), Marshallagia marshalli (15.2%), Nematodirus oiratinus (1.1%), Trichostrongylus axei (3.3%) were found in stomach. Moniesia expansa (1.1%), Bunostomum phlebotomum (10.9%) were found in small intestine. Trichocephalus ovis (18.5%), Oesophagostomum venulosum (7.6%) and O. dentatum (1.1%) were found in caecum. Chabertia ovina (28.3%) was found in large intestine. Forty-four helminth associations were separated in the roe deer examined.
Key words: roe deer, Capreolus capreolus, helminth biodiversity, Ukraine.

Indices of Springtail (Collembola) Population of the Landscape Park “Dniprovs’ki Ostrovy” Fauna. Tarashchuk M. V., Bezkrovna O. V. — In investigated edafotopes of 32 riverbed islands of the Kyiv Dnipro Region 43 species of springtails from 28 genera of 12 families are fixed. The species Orthonychiurus stachianus (Bagnall) is noted for the first time for the territory of the Ukraine. Floodland forest populations demonstrate the predominance of atmobiontic surface forms in the biomorphic spectrum, mono-domination of the wide-valentic plastic forms and the significant part of drymesophilous forms. In this latter case the specific hygromesophilous and hygrophilous forms of floodlands most frequently pick up 3% to 9% share of participation in the community. The insufficiency of the aeration of deep soil layers limits the development of euedaphic component of island fauna. The insular population of springtails under the hot and dry conditions approaches by the biomorphic structure characteristic to the zonal associations. The taxonomic structure of intra-zonal fauna is characterized by the inverted reaction of the “aridic and humidic weights”, which is manifested in the growth in the faunistic spectrum of the part of humidofilic taxa with the aridization of climate. The anthropogenic factor with the background of the topographical-climatic special features of intra-zonal edaphotopes, xerotization of microclimate is the main reason for the decrease ecological and faunistic indices of the springtails’ associations, as the species richness, population quantity, diversity of the biomorphic, biotopic and hygropreference structures.
Key words: Collembola, collembolans, fauna, taxonomic structure, dominance, biotopic groups, hygropreferences, biomorphes.

Ethological Aspects of Honeybee Apis mellifera (Hymenoptera, Apidae), Adaptation to Parasitic Mite Varroa destructor (Mesostigmata, Varroidae) Invasion. Akimov I. A., Kiryushyn V. E. — Some ethological aspects of A. mellifera Linnaeus, 1758 (Hymenoptera, Apidae), adaptation to parasiting the mite V. destructor Anderson et Trueman (Mesostigmata, Varroidae) are shown. The basic complexes of behaviour reactions, directed on a fight against the parasitic mites of bees brood at the genus Apis are shown, their comparative efficiency under various conditions and evolutional perspective. Possibility of ethological adaptation of honey bee to V. destructor parasiting, direction of selection by this sign and influencing of human on parasitic-host system was discussed. An approach to the selection of bees with the purpose of resistanse to varroosis promoution is proposed.
Key words: Apis mellifera, Varroa destructor, hygienic behaviour of bees, resistance, adaptation, selection.

Participation of Germaraphis Aphids (Homoptera, Aphidinea) in Weight Fractions of the Rovno Amber and their Syninclusions with Ants. Perkovsky E. E. — The percentage composition of the aphid genus Germaraphis in the Rovno amber samples of three weight ranges (< 1.5g, > 1.5 < 6.5g, and > 6.5g after primary treatment) is described for the first time. In the biggest pieces the share of genus Germaraphis was 2 times more than in smaller pieces (< 10 g or < 6.5 g after primary threatment) and only 1,5 times less than that of the worker ants there. In the smaller pieces the share was 4,3 times less than that of the worker ants. Our data reveal that symbiotic relationships of the dominant formicine ant Lasius schiefferdeckeri and dominant dolichoderine ant Ctenobethylus goepperti with the long-beaked aphids were intensive in the both Rovno and Baltic amber forests. However, they were organized differently there. Particularly, in the Rovno amber, Ctenobethylus was usually associated with G. dryoides above lower part of trunk (or possibly along the whole tree trunk), while L. schiefferdeckeri was associated with other three species of Germaraphis mostly on the lower part of the tree trunk (possibly also on its thick branches). In the Baltic amber, the only association recorded is between G. dryoides and each of the above ant dominant species.
Key words: syninclusion, Aphidinea, Formicidae, Eocene, amber, Ukraine.

The Biological Peculiarities of Shel-duck Tadorna ferruginea (Aves, Anseriformes) in Askania-Nova. Mezinov À. S., Zubko V. Ì. — According to the results of long-term monitoring for the local population of the ruddy shel-duck Tadorna ferruginea Pallas, 1764 its adaptation peculiarities for the coexistence on the ponds of Askania-Nova in the community of various species were found. The breeding nestlings of the ruddy shel-duck in the formed brood (hatch) with the same species parents (or foster-parents) helps them to save the nature stereotype of behavior and its biological peculiarities. The breeding nestlings with the foster-parents other species as the musk-duck, the silvery duck conducts to the appearance some signs of synanthropy, more tolerance to the man and other species of birds. In contrast to birds of natural populations, the colonial type of nesting is developed in the Askanian ruddy shel-duck population, and the polygamy and homosexualism become more common, as well as the joint laying with other species of anseriform birds is noted. Such adaptations guaranteed the successful condition of population and the bird's productivity entirely fits its range for the nature populations of birds. The birds bred under semi-free conditions normally migrate and survive in the wild nature. The constant and careful human influence on the process of birds conservation is one of the main factors in the reconstruction and conservation the population of ruddy shel-duck in the South of Ukraine.
Key words: ruddy shel-duck, adaptation, semi-free conditions, local population, the South of Ukraine.

Sexual Reproduction Peculiarities of Planarians by the Example of Dugesia lugubris and Dendrocoelum lacteum (Turbellaria, Tricladida). Chernysheva A. O., Kanana Yu. P. — Fertility of Dugesia lugubris in a laboratory culture after one copulation was identified to be from 1 to 3, on the average 2 cocoons with 2–3 worms, a maximum of 6 and 2–3 cocoons (with 2 to 5 worms in each) in Dendrocoelum lacteum, respectively. The cocoon filled with yolk cells is formed in 5–7 hours after copulation; egg cells enter the cocoon later. It is found that the fertilization of egg cell takes place in the oviduct of planarian. The rhythmicity of cell fission activity in vitelline gland, testis and ovary is traced. These peculiarities of the planarian reproduction to some extent are attributed to the presence of two-component female gonad and ectolecithal eggs.
Key words: turbellaria, planaria, fertility, fertilization, cocoon, egg cell.

Records of the grassflies (Diptera, Chloropidae) of the Palaearchearctic Geoelement on the Altai Mountains. Nartshuk E. P. — Four species of grassflies (Diptera, Chloropidae), Lasiambia shatalkini Nartshuk, 1986, Siphunculina stackelbergi Duda, 1933, Centorisoma flavum Nartshuk, 1965, and Cetema bispinosa Duda, 1933 are found on the Altai Mountains. These species were hitherto known from the Far East of Russia and the latter also from North Mongolia. The new records clarify the western border of ranges of these species. Distribution of the genera Centorisoma Becker, 1910 and Cetema Hendel, 1907, each including in the Palaearctic two groups of species with centres of distribution in Europe and the Far East, permits to consider the origin of these genera from Tertiary Turgai forests.
Key words: Diptera, Chloropidae, Altai Mountains, new records.
