The Description of Rhabdias globocephala
(Nematoda, Rhabdiasidae) from the New Host Buergeria pollicaris (Amphibia, Rhacophoridae).
Kuzmin Yu. I. — Parasitic nematode Rhabdias globocephala Kung et Wu, 1945
previously known only from the type host, Microhyla ornata from China, is described
from a new host, Buergeria pollicaris (Werner, 1914). Differention of the species
from closely related R. sphaerocephala Goodey, 1924 is amended based on the shape
of anterior cuticular swelling, buccal capsule position, and relative length of oesophagus.
The differentiation of R. globocephala from 4 sympatric species of the genus: R. bicornis
Lu, 1934, R. bufonis (Schrank, 1788), R. incerta Wilkie, 1930 and R. nipponica Yamaguti,
1935 is also provided.
Key words: Rhabdias, R. globocephala, Buergeria pollicaris, Rhacophoridae, Microhylidae.

Variability of the Polymorph Structure of
the Urban Colonies of the Introduced Species Cepaea hortensis (Gastropoda, Pulmonata).
Sverlova N. V. — The variability of the polymorph structure of the colonies
of C. hortensis (Mu#ller, 1774) was analysed in partly or completely isolated urban
biotopes of Lvov. It is obvious that all the studied colonies were formed by the descendants
of the relatively small number of the primary introduced individuals. This explains
considerable similarity of the polymorph structure in the different parts of Lvov.
At the same time the rudiments of the genetics differentiation were registered both
in the neighbouring colonies of C. hortensis and for the different parts of the city.
The anthropogenic barriers of definite type are contributing to genetics and polymorph
differentiation.
Key words: land molluscs, Cepaea, polymorphism, introduction, urban biotopes.

Oak Leaf-Mining Moth and Other Mining Lepidopterans
on Oak. Communication 3. Natural Enemies of Oak Mining Pests in Ukraine and Adjacent
Territories. Nikitenko G. N., Fursov V. N., Sviridov S. V., Gumovsky A. V., Kotenko
A. G., Narolsky N. B., Tolkanits V. I. — Complex of parasites and predators
of oak leaf-mining moth (Acrocercops brongniardella) and other most important oak-mining
lepidopterans was studied in Ukraine and adjacent territories (Russia and Byelorussia).
Thirty-six species of parasites from 2 superfamilies were found: 16 species belong
to Ichnemonoidea and 20 species to Chalcidoidea. Sixty-one predaceous species feeding
on oak-mining lepidopterans were found: 12 species of 3 families belong to Aranei,
and 49 species of 6 orders and 12 families belong to Insecta. These species are major
factor of natural regulation of the number of oak’s mining moths (in some areas the
number of pests reduced to 10–75% because of activity of entomophages). The system
of integrated pest management is proposed including the application of analogy of
natural development’s regulator (preparation “insegar”) and calculation of activity
of entomophages. The number of oak’s mining moth (Acrocercops brongniardella) reduced
to 58–97% a as result of this system.
Key words: Acrocercops brongniardella, oak leaf-mining pests, parasites, natural enemies,
entomophages.

Correlation Between Spring Arrival Data of
Birds and First Flowering Data of Plants in the Forest and Forest and Steppe Areas
of Eastern Europe. Communication 1. Ratio of Significant Correlations. Fesenko H.
V. — Correlation analysis was carried out in order to find relations between
the dates of spring arrival of birds and dates of first flowering of plants, basing
on data of phenological events that were collected in the vicinities of Sumy city
and Zhytomyr city (Ukraine) situated in the Forest-Steppe zone, in the Iygheva Town
(Estonia) located in the Forest zone of Eastern Europe as well. After that, a pattern
of ratio of significant correlations was studied among short-distance and long-distance
migrants, as well as among four feeding groups of migratory birds living mainly on
either vertebrates or invertebrates, or plants, both or plants and invertebrates.
As a result, it is revealed that short-distance migrants predominated over long-distance
migrants in significant correlations with dates of first flowering of plants and frequency
of the correlations is more in the formers than the latters near Sumy city — up to
2.3 times, by Zhytomyr city — up to 1.5 times ànd in Iygheva Town — up to 1.3 times.
Among feeding groups of migrants, significant correlations were frequently registered
both for birds living mainly on plants and for birds feeding on plants and invertebrates
in equal parts.
Key words: spring arrival, flowering, short-distance and long-distance migrants, feeding
groups, Forest-Steppe and Forest zones, Eastern Europe.

Anomalies in Development of Gonads in the
Green Frogs of the Rana esculenta ñomplex (Amphibia, Ranidae) from Ukraine. Reminnyi
V. Yu. — The results of analysis of 238 virile specimens of Rana ridibunda,
87 R. lessonae, 96 R. kl. esculenta, 48 R. temporaria and 56 R. arvalis from 7 regions
of Ukraine are represented. Ten types of constitution anomalies and position of spermaries
in Rana kl. esculenta males, including two cases of androgyny are recognized. High
frequency of deflections in constitution and position of spermaries in Rana kl. esculenta
males is shown, in connection with their hybridogenetic origin. The magnitude of spermary
asymmetry in Rana kl. esculenta compared with parent and closely related species is
reliably greatest. By the set of 16 morphological characters and 8 indexes, the hermaphrodite
frogs differ from females more than from males. Males with underdeveloped spermaries
and missing secondary sexual characters are similar morphologically to females.
Key words: Rana ridibunda, R. lessonae, R. kl. esculenta, anomaly, asymmetry, morphology,
testes, hermaphrodite.

A Unknown Representative of Arthropoda from
the Black Sea Anaerobic Zone. Sergeeva N. G. — A previously unknown metazoan
animal, found in the Black Sea hydrosulphuric zone bottom sediments, at 2120 m depth
is described. The animal has several morphological and anatomical characters showing
its belonging to the phylum Arthropoda; however, it cannot be attributed to any known
arthropod class. Lack of sufficient material (a unique specimen is available) at the
present stage of investigation does not permit to make final conclusion about the
status of the organism described in the animals kingdom system. The specimen is deposited
under the title “Form 14” in the Department of Shelf Ecosystems of the Institute of
Biology of the Southern Seas of the NAS of Ukraine (Sevastopol).

The Season Dynamic of the Extensity of Varroatosis
Invasion in Adult Bees Apis mellifera by Mite Varroa (Parasitiformes, Varroidae) in
Different Regions of Ukraine. Nemkova S. N. — The peculiarities of dynamics
of a level of varroatosis in adult bees in the Zacarpatye, Poltava regions and in
the Crimea in 1996–1997 years are specified in work. Is revealed, that the speed of
development of varroatosis invasion during a season is higher in of bees family carpathian
race, and also at intensive conducting beekeeping and the concentrations of honey
bee colonies are more, than 12–15 ones on the square. In August, when it formed of
winter generating the bees, the parameters of a extensity of varroatosis invasion
exceeded allowable norms (2%) in 2,7–3,6 times irrespective of race of bees both climatic
zone and technology of beekeeping. Without realization of medical processing’s these
parameters reached of critical values in September (mote then 10%), that represented
threat to vitality of the separate adults bees and honey-bee colony as a whole.
Key words: carpathian and ukrainian stepping races bees, Varroa, extensity and intensity
