as of the Subfamily Eulachninae of the Family Lachnidae (Homoptera, Aphidoidea). Mamontova
V. A. — The polemics with J. Sorensen concerning the phylogenesis and the
place in the system of the mentioned aphids is represented. The must important phylogenetic
characters are established among morphological featurees of Lachnidae. Phylogenetic
relationships of the generŕ Schizolachnus Mordvilko, Cinara Curtis and Eulachnus del

mollusks, their distribution and ecology in the North-Western part of the Sea of Azov
and adjacent lagoons (Molochnyj and Utlyukskij) are studied. Altogether, 74 species
of mollusks registered in the region; 51 species belong to the class Gastropoda, whereas
the class Bivalvia is represented by 23 species. Seven species are indicated here
in the Sea of Azov for the first time. Original data on qualitative and quantitative

The Gastro-Intestinal Parasites of the Przewalski
Horse (Equus przewalskii) in the Chîrnobyl Exclusion Zone. Slivinska K. A., Dvojnos
G. M. — Results of parasitological investigation of Przewalski horse Equus
przewalskii Poljŕkov, 1881 from the Chîrnobyl Exclusion Zone (CEZ) are presented.
The diagnostic technique of deworming revealed for the first time that gastro-intestinal
parasites community of Przewalski horse includes 32 species of 5 families and 3 classes
(29 species of nematodes, 1 species of cestodes and 2 larvae of botflies) in the CEZ.
The core of the community is formed by 4 species: Cylicostephanus minutus Yorke et
Macfie, C. longibursatus Yorke et Macfie, Cyathostomum catinatum (Looss), Cylicocyclus
nassatus (Looss). Observations show that horses keep their typical biological features
and high stability to invasions. It is revealed in a good clinical horse state and
number growth of herd. It argues in favour of using of Przewalski horses in renaturalization
of territories.
Key words: gastro-intestinal parasites, Przewalski horse, Equus przewalskii, Chîrnobyl

Comparison of Wolbachia Bacterial Density
in Females of Four Thelythokous Strains of Trichogramma cordubensis and T. evanescens
(Hymenoptera, Trichogrammatidae). Pascal C., Pintureau B., Katchadourian C., Grenier
S., Bolland P., Robin C., Vallier A. — The endosymbionts of the genus Wolbachia
infect numerous arthropods and nematods, and often cause different effects on the
reproduction of these hosts. The endosymbiotic bacteria Wolbachia induces the thelytokous
mode of reproduction in the egg parasitoids of the genus Trichogramma. The Dot-blot
technique was performed to compare the symbiont Wolbachia density using the wsp gene
of Wolbachia and the 18S gene of Trichogramma. It was established that Wolbachia density
is not different in two host species, Trichogramma cordubensis Vargas et Cabello and
T. evanescens Haliday.
Key words: Hymenoptera, Trichogramma, egg parasitoids, Bacteria, Wolbachia density,

The Springtailes (Collembola, Entognatha)
of the Urbanisric Landscapes of the Kryvyj Rig City. Tarashchuk M. V., Horban T. V.
— The collembolan associations in five city regions under different technogenic pollution
power were investigated. The park zones, residential districts, kindergartens, roadside
zones were studied in the each region. The model data indices of soil pollution were
taken in the steppe plot near Kamjane Pole settlement, 4 km from the city of Kryvyj
Rig. The 63 species of 38 genera of 10 families were found, of them 13 species and
one genus for the first time in Ukraine. The most significant special richness were
demonstrated for Zhovtnevy region (30 species, 19 genera, 8 families) and park zones
(28 species, 19 genera, 6 families); the least one noted for Dovgyntsivsky region
(11 species, 10 genera, 5 families) and roadside zones (13 species, 12 genera, 7 families).
The preliminary ecological and climatic estimation of city-landscape territories and
of the city regions were made using taxonomic and faunistic analysis and several taxonomic
indexes. The degree of anthropic influence may be connected with the faunistic impoverishment
especially by the humidofilic component of fauna.
Key words: springtails, collembolan associations, taxonomical structure, taxonomic
and faunistic analisys, city-landscape territories, technogenic pollution.

The Structure of Mesofauna Community in Protective-Decorative
Plantations on Mine-Coal Dumps of the Donetsk Basin. Kirichok L. G., Illenko M. M.,
Bezkrovna O. V. — The results of the soil mesofauna investigation in protective-decorative
plantations of trees on the mine-coal dump are presented. 20 species of springtails
and the representatives of 10 other groups of invertebrate animals were registered.
Their population density depends on vegetation development and edaphotope, position
of the site on catena and slope exposition. The most suitable conditions for soil
zoocenosis development are formed in plantation of tree-bush type and shady tree type
with bushes.
Key words: dump, protective-decorative plantations, mesofauna, microarthropods, springtails,

The Peculiarities of the Intrapopulation
Conchiometry Variability of the Land Snail Brephulopsis bidens (Gastropoda, Pulmonata,
Buliminidae). Kramarenko S. S. — The shell variability of 11 morphometric
traits of the land snail Brephulopsis bidens (Krynicki, 1883) was examined, using
PCA. Studies were carried out on 175 individuals from the Simferopol (Crimea) suburb
(one local population) during 1989–1991. It was shown, that a variation structure
of the first three PC’s was not differentiated practically during the study period.
The PC 4 is the result of the environmental influence and it is always similar to
all individuals survived during the aestivation period.
Key words: land snail, Brephulopsis bidens, shell variation, PCA, aestivation period,

Helminthes of the Genus Trichinella (Nematoda,
Trichinellidae) Amongst Wild Mammals in Polesie and Carpathian. Didyk J. M.
— Trichinella larvae were detected in 16% of wild animals: bear, wolves, red foxes
and marten. The largest number of infected animals are recorded in the Trancarpatian
Region. The largest number of larvae per gram of muscle tissue was found in the legs
in wolves and foxes. It is shown that rodents do not participate in circulation of
Trichinella on this territory.

Species Composition and Number of Birds
of Prey on Morthern of Ukraine in the Winter Periods 2000–2003 Years. Kostyushin V.
A., Domashevsky S. V. — Automobile-facilitated counts of birds of prey were
conducted during winter periods 2000–2003 in Kyiv, Chernihiv and Zhytomyr Regions
of Ukraine. The total length of the counting rout is 1047 km. Ten species of birds
of prey were registered: Hen Harrier (Circus cyaneus) — 18 individuals; Northern Goshawk
(Accipiter gentilis) — 11; Sperrowhawk (Accipiter nisus) — 17; Rough-Legged Buzzard
(Buteo lagopus) — 491; Common Buzzard (Buteo buteo) — 359; Long-Legged Buzzard (Buteo
rufinus) — 1; birds Buteo spp. — 75; Golden Eagle (Aquila chrysaetos) — 1; White-Tailed
Eagle (Haliaetus albicilla) — 1; Merlin (Falco columbarius) — 11; Kestrel (F. tinnunculus)
— 3. According to the calculation results, the general density of birds of prey was
1.17 individuals per square kilometer, including 1.05 individuals/km2 of B. lagopus
and B. buteo (0.61 and 0.44 individuals/km2 accordingly). Density of the rest of species
is significantly lower: A. nisus — 0.047; C. cyaneus — 0.033; F. columbarius — 0.019;
A. gentiles — 0.015 individuals/km2. For all the remaining species, which are represented
by individual findings, density was not calculated. Taking into account the data on
density of B. lagopus and B. buteo, and the area of biotope preferred by them during
winter period, the total number of each of these species in the Kyiv Region may be
approximately assessed as 8634 — 13 046 and 5292 — 8416 individuals accordingly.
Key words: birds of prey, winter, number, density, northern part of Ukraine.
