Peculiarities of the peritrophic matrix in the midgut of tick females of the genus Ixodes (Acarina: Ixodidae). P. 3-11.
The formation of the peritrophic matrix in the midgut of females of 5 ixodid tick species (Ixodes pacificus, I. pavlovskyi, I. persulcatus, I. ricinus and I. scapularis) was studied by means of light and electron microscopy in different periods of the feeding and after detachment. The formation of the peritrophic matrix started when the first food portions came into the gut lumen, 9—12 hours after the attachment. Renovation of the peritrophic matrix took place during the whole feeding period; every new generation of midgut cells synthesized their own matrix. It was deposited on the apical surface of every midgut cell in the beginning of differentiation, and was functioning during the life of the cell. The peritrophic matrix separates spaces of the cavitary and cytozoic digestions.

The formation of the peritrophic membrane in the gut of Culicoides punctatus (Diptera: Ceratopoginidae). P. 12-19.
Using light and electron microscopy, the structure of the peritrophic membrane (PM) was studied in females of the biting midge Culicoides punctatus (Mg.) during the process of blood meal digestion. The PM formation occurs in the posterior part of midgut and lasts during the most time of the digestive cycle. The PM precursors are probably not associated with any intracellular granules. The PM consists of two main components: light structural component and dark amorphous matrix, both of which are directly released from the entire microvillar surface. The aggregation of secreted components takes place in the gut lumen to form gel-like multilayered PM up to 6 µm thickness with bundles of microfibrills situated in the PM surface facing the lumen. Similarities and differences of the PM formation in most groups of blood-sucking insects are discussed.

Discriminatioin of subspecies in a polymorphic species Hyalomma marginatum (Acari: Ixodidae) based on adult stage. P. 20-32.
Morphological characteristics allowing discriminating adult stages of four subspecies of Hyalomma marginatum (H. m. marginatum, H. m. turanicum, H. m. rufipes and H. m. isaaci) are displayed. The subspecies status of all named forms is confirmed. The main discriminating characters for adults of these subspecies are peculiarities of scutal or conscutal puncta-tions and a shape of the dorsal tale of spiracular plates (Fig. 1, I—4; 2, 4—7; 4, 7, 2; 5, 7, 2; 6, 5—8). Nevertheless, there are a number of facts, which support only the subspecific rank of these taxa. In Turkmenistan, there is a zone inhabited by forms, adult stages of which are morphologically intermedial between H. m. marginatum and H. m. turanicum. A zone of intermedial forms between H. m. turanicum and H. m. rufipes exists in Arabian Peninsula (Hoogstraal e. a., 1981). An absence of clear discriminative characters between immatures of H. m. marginatum, H. m. turanicum and H. m. rufipes also confirms the subspecies level of these taxa. H. m. isaaci is the most differentiated subspecies. It is difficult to estimate relationships between the latter subspecies and H. m. turanicum because of a deficit of materials. However, clear morphological differences of H. m. isaaci immature stages from other subspecies were noticed (Apanaskevich, 2003). Therefore, it is quite probable that H. m. isaaci might deserve the species rank. Further analysis of relationships between subspecies of H. marginatum needs additional materials represented by all stages from zones containing intermedial forms between recently recognized subspecies.

Parasite fauna of the water vole Arvicola terrestris and its nests in south of Western Siberia. P. 33-45.
Fauna of parasitic and free-living arthropods associated the water vole Arvicola teresiris and its nests in various landscape zones and subzones of the south of Western Siberia has been studied. Total abundance of gamasid mites and ticks (Gamasoidea, Ixodidae), fleas and nidicolous arthropods in nests is high, and the set of nidicolous and parasite species is quite diverse, but everywhere the parasite fauna is characterized by a small amount of species reaching a high abundance: Laelaps muris on the voles, Haemogamasus ambulans in nests, Ixodes apronophorus and Megabothris walkeri both on the voles and nests. Parasitic arthropods living on the voles or in their nests are characterized by higher and stables indices of infection, while these parameters for free-living arthropods were variable. The list of mesostigmatic mites parasitizing the water vole and its nests in the south of Western Siberia (Adamovich, Krylov, 2001) has been considerably supplemented. In total, the fauna of parasitiform mites (Acari: Mesostigmata and Ixodiddes) and fleas (Siphonaptera) associated with the water vole in the south of Western Siberia is represented by 97 arthropod species of 19 families, including 74 species of mesostigmatic mites (Gamasoidea), 6 species of ticks (Ixodidae) and 17 species of fleas.

Seasonal dynamics of infecting ability of the flea Citellophilus tesquorum altaicus in the Tuva natural focus of the plague. P. 46-52.
The infecting ability of the fleas Citellophilus tesquorum altaicus Ioff, 1936, the main plague vectors in the Tuva natural focus, was experimentally studied in different periods of the epizootic season. Seasonal dynamics in the efficiency of infecting the long-tailed Siberian souslik with the plague causative agent through flea bites was noticed. Seasonal differences in infectivity of the "blocked" flea bites are revealed. An increase of infected experimental animals with a generalization of infection process in the period of epizooty activation in the natural focus was observed. A resistance of the long-tailed Siberian souslik to the plague agent infection through flea bites in the spring season was registered.

Parasite fauna from loaches (Cobitidae) of water basins in the Primorsk Territory. P. 53-67.
Parasite fauna from loaches was examined in the period 1985—1999 in water basins of different parts of the Primorsk Territory: south (rivers Pojma and Razdolnaya, lake Bol'shoye Mramornoye), north-east (river Yedinka), west (rivers Komissarovka, Ilistaya, Mel'gunovka), center (upper part of the river Ussuri, river Axsen'evka). The 159 specimens of five loache species have been examined. The parasite fauna is represented by 96 species, including 37 protozoan species (flagellates — 4, coccidians — 2, myxospori-dians — 10, infusorians — 21), plathelminthes — 45 (monogeneans — 18, trematodes — 18, cestodes — 9), acanthocephalans — 2, nematodes — 8, arthropods (crustaceans) — 1, mollusks — 3 species.

Monocercus dokuchaevi sp. n. (Cyclophyllidea: Dilepitidae) — a new species of cestodes from shrews of the North-Eastern Asia. P. 68-73.
A new cestode species, Monocercus dokuchaevi sp. n. is described from shrews of the genus Sorex from the Middle Kolyma plateau (Magadan Province). The new species is most closer to M. soricis (Neiland, 1953) by having regular alteration of genital atriums in the short strobila (up to 10 mm only). The size of rostellar hooks in M. dokuchaevi is intermedial between those in M. soricis and M. arioni (Sibold, 1850). In Monocercus dokuchaevi, the length of rostellar hooks is 0.038—0.045 mm (average 0.04 mm), in M. arioni, average is 0.05 mm, in M. soricis, limits are 0.027—0.033 mm. Two other species of the genus, M. baicalensis Eltyshev, 1971 and M. estavarensis Euzet et Jourdan, 1968, have much longer rostellar hooks, 0.07—0.08 and 0.092—0.106 mm, respectively, whereas the genital atriums in these species are altered irregularly.

Effect of trematod infection and different concentrations of detergent onto physical and chemical characteristics of haemolymph of Planorbarius corneus (Mollusca: Pulmonata). P. 74-80.
Effect of trematod infection and different concentrations of detergent (20, 50, 80 mg/dm3) onto physical and chemical characteristics of haemolymph of Planorbarius corneus (content of Hb, density, active reaction, amount of Hb per unit of total mass and soft mass of the body) have been investigated. It was noted that all changes of named characteristics caused by detergent were more pronounced in infected mollusks.

Peculiarities of the parasite fauna of the landlocked Atlantic salmon Salmo salar in the basin of Namsen river. P. 94-97.
The 26 specimens of the landlocked Atlantic salmon Salmo salar L. from Namsen river and its tributary Melingselva river (central Norway) were studied by the method of complete parasitological examination in the period of 1997—1998. The 15 parasite species have been recovered. Ration of parasite with a direct and complex cycle is approximately equal, 6 and 9 respectively. Larval stages of parasites predominate among the parasites with a complex cycle. The parasite fauna fond in the landlocked Atlantic salmon is most similar to that in youngsters of the lake salmon (Salmo salar morpha sebago Girard) and the migrating Atlantic salmon (Salmo salar L.).
