Allocricetus and Ñricetulus
(Cricetinae, Rodentia) at the Pleistocene of Ukraine. Stadnik
Î. ². — Illustrated description of the fossil remains
of Allocricetus and Ñricetulus species from the Pleistocene deposits
of Ukraine and adjacent territories of Russia. They belong to
three species: Allocricetus ehiki, Allocricetus bursae and Ñricetulus
sp. ex gr. kipianii. The morphological comparison of the material
with that from Central and West Europe is given. The temporal
distribution of these species and their phylogenetic relations
are discussed.
Key words: Cricetinae, Allocricetus, Cricetulus, Eopleistocene,
Neopleistocene, Ukraine.

Ecological Characteristics
of Varroa destructor (Parasitiformes, Varroidae) and Its Environmental
Capacity as a Key Factor for Development of Varroosis Panzootia.
Akimov I. A., Korzh O. P. — By means of formalized schematic
models of relationship with hosts the varroa mite uniqueness as
a parasite is shown. The life cycle of this species requires the
change of a host species at different stages of their development
and physiological states. Thus the mite parasitizes not only a
separate bee but a whole hive. The fact that the whole hive but
not a single bee dies during varroosis development supports this
idea. The impetus for this type of parasitism is the relative
constancy of the environment in the hive supported by bees even
in winter. Exactly this fact causes high pathogenicity of the
varroa for the honey bee and its control complexity.
Key words: Varroa destructor, Apis mellifera, varroosis, carrying
capacity, life cycle, development stage, environmental factors.

Synanthropy of Bloodsucking
Mosquitoes (Diptera, Culicidae) under Conditions of Kyiv. Kilochitskaya
N. P. — The 35 anthropophilic species are analyzed. The
main tendancies of adaptations tending the transition of bloodsucking
mosquito to synanthropic existence are considered. It is shown,
that certain part of bloodsucking mosquitoes species inhabiting
natural biocoenoses have been already adapted before the assimilation
into the anthropogenic landscapes.
Key words: bloodsucking mosquitoes, Culicidae, synanthropy, Kyiv.

Interrelations Between
Different Forms of Group Variability of Quantitative Traits in
Microtus socialis (Cricetidae, Mammalia) in the Peak Phase of
Population Abundance. Peskov V. N., Sinyavskaya I. A., Emelyanov
I. G. — The amount of input and the interrelation of
various forms of group variability of quantitative traits in general
morphological disparity of M. socialis in the peak phase of the
population abundance was studied. It was found that the variability
of 4 exterior and 11 interior traits are determined primarily
by the age of the animals, whereas the influence of sex and the
season is very low. With ageing, the intensity of sexual differences
and seasonal variability increase. The correlated variability
of morphological traits was almost the same (Rs = 0.820–0.98)
in males and females during different seasons.
Key words: Microtus socialis, group variability, age variability,
sexual differences, seasonal variation.

Lake Frog, Pelophylax
ridibundus (Amphibia, Anura), Olfactory Analyzer Peripheral Part
Morphogenesis. Kovtun M. F., Stepanyuk Ya. V. — By means
of light microscopy method the features of lake frog, Pelophylax
ridibundus (Pallas, 1771), basic olfactory epithelium were studied
starting from the embryonal period till complete finishing of
morphogenesis and transition to the land life. It is found, that
during ontogeny frog nasal bags are differentiated into three
parts. Besides the basic nasal cavity, which is covered by basic
olfactory epithelium, during the period of metamorphosis additional
cavities are created, namely medium and lower. Lake frog vomeronasal
organ is located in the medial corner of the lower nasal cavity.
Key words: Amphibia, olfactory system, olfactory epithelium, vomeronasal
organ.

Polar Cartilages and
Formation of Crista Sellaris in Grass Snake, Natrix natrix (Ophidia,
Colubridae), Chondrocranium at the Early Stages of Embryogenesis.
Sheverdyukova H. V. — The initial developmental stages
of grass snake’s, Natrix natrix Linnaeus, 1758 chondrocranium
are described. Three paired structures form the floor of N. natrix’s
neurocranium: cranial trabeculae, polar cartilages, and parachordals.
The primordiums of polar cartilages and their independent centers
of chondrification are identified at the stage 26 of development
for the first time for N. natrix and snakes in general. The participation
of these structures in the formation of crista sellaris and carotid
foramina is proved.
Key words: polar cartilage, crista sellaris, chondrocranium, embryonic
development, carotid foramina, Natrix natrix.
