Revision of the superfamily Clinostomoidea and analysis of its system.
On the basis of modificational variability and taxonomic characters a revision of taxons was carried out and the system of trematodes of the family Clinostomidae was revised.

New data on the trematodes from fishes of Atlantic coast of Africa. P. 12-17.
Prudhoeus africanus sp. n. (fam. Fellodistomidae) and Hysterorchis atlanticus sp.n. (fam. Monorchiidae) from fishes inhabiting the eastern Atlantic are described. Steringophorus pritcharda, Diphterostomum americanum, Glomericirrus macrouri, Dinosoma triangulata and Paraccacladium jamiesoni were found for the first time. Lepidapedon hancocki Manter, 1940 and L. ghanensis Fischthal et Thomas, 1970 are considered as synonyms of L. nicolli Manter, 1934.

Pathomorphological changes in formed elements of haemolymph of freshwater molluscs (Bivalvia, Unionidae, Anodontinae) at their infection with parthenites of trematodes. P. 18-23.
The effect of trematode infection on qualitative and quantitative indices of formed elements of haemolymph of Anodonta cygnea (L.), Colletopterum piscinale falcatum (Drouёt) and Colletopterum ponderosum rumanicum Bourguignat was studied. Diminution of amoebocytes and of their nuclei, loosening of karyo- and cytoplasm due to their vacuolization,change in the location of the nucleus in cells, karyopycnosis, karyorhexis and karyolysis, basophilisation of cytoplasm of eosinophilous amoebocytes, increase in the number of senescent cells and intensification of phagocytosis was noted.

The structure of bacillary bands of capillariids (Nematoda, Capillariidae) and taxonomic significance of this character. P. 24-29.
Bacillary bands were studied in 13 species of nematodes of the family Capillariidae, representatives of 6 genera: Capillaria, Thominx, Eucoleus, Armocapillaria, Skrjabinocapillaria and Hepaticola. Analysis of the obtained data has shown that the number, topography, relative width of bacillary bands as well as the structure and size of subcuticular hypodermal cells forming the bacillary bands can serve as differential characters of both generic and specific taxons.

Recent studies on marine fish parasites and diseases. P. 30-35.
Progress in research on marine fish diseases and parasites in the United States can be discussed in three categories: diseases and parasites in natural populations, disease in degraded habitats, and disease in marine aquaculture. Principal interest is in the effects of diseases on wild or cultured populations of economic importance, but there are subsidiary interests in diseases and parasites as indicators of environmental changes, in public health aspects of fish diseases and parasites, and in effects of parasites on market quality of fish products. Studies of natural populations of fish have concentrated on pathogens and parasites which occur at epizootic levels. Important here are viral diseases, particularly viral erythrocytic necrosis, some bacteria, such as Pasteurella piscicida, and a systemic fungus disease caused by Ichthyophonus hoferi. Attempts to quantify the effects of disease on fish abundance have increased, and there is growing acceptance of the conclusion that disease related mortality is a significant environmental factor in the sea. Recent emphasis has been placed on diseases which may be associated with estuarine-costal pollution in the vicinity of human population centers. Several diseases and disease signs— notably integumental lesions such as ulcers, fin erosion, papillomas, and lymphocystis — have been associated (some only circumstantially) with environmental degradation. Chromosomal anomalies and developmental abnormalities (skeletal malformations) have been studies also, from the viewpoint of increased prevalences in polluted zones. An important role for facultative microorganisms — particularly bacteria of the Vibrio, Pseudomonas, Aeromonas group — has emerged. Evidence is accumulating for localized effects of pollutants on fish populations, and for the utility of certain disease signs as indicators of environmental stress. The slow but continuous development of marine aquaculture in the United States has been accompanied by increasing attention to diseases and disease control. Sea cage rearing of Pacific salmon (genus Oncorhynchus) on both coasts has been possible only by control of vibriosis (principally Vibrio anguillarum). Effective polyvalent vaccines now limit the problem, but other diseases, such as bacterial kidney disease (BKD) and furunculosis (caused by Aeromonas salmonicida) persist. Additionally, certain of the salmonid virus diseases seem capable of transmission and of causing mortality of salmon in sea water. Parasites which reduce market quality of marine fish include the histozoic myxosporidan Protozoa and larval helminths, particularly larval nematodes. Few of these are of public health concern, but many result in rejection of infected fish as food. With the impetus provided by declining marine fish stocks, increasing coastal pollution, and developing aquaculture, fish disease research has expanded in recent decades. There is still a need for quantification of disease effects on population abundance.

The migration of microfilarians Thamugadia ivaschkini from the intestine to haemocoel of sand flies of the genus Phlebotomus. P. 36-41.
Sand flies of Ph. papatasii and Ph. caucasicus were experimentally infected with Th. ivaschkini. At daily fluctuations of air temperature from 27 to 32°C and relative air humidity from 30 to 60% viable microfilarians migrate into haemocoel within the first 5—6 hours after the bloodsucking of vectors, before the peripheral membrane is completely formed. Most parasites leave the intestine before the formation of a blood clot, within the first 1.5 hour after feeding. The number of larvae overcoming the intestinal barrier (at studied levels of infection) does not depend on the number of devoured microfilarians and is close to 100%. Sand flies of the genus Phlebotomus lack physiological mechanisms limiting the migration of microfilarians from the intestine that causes a high mortality of these vectors at intensive infection.

Development of ixodid ticks (Ixodidae) in drained parts of the forests of the Novgorod region. P. 42-46.
Data of observations on the development of Ixodes persulcatus, I. ricinus and Dermocentor pictus in drained parts of small-leaved and coniferous forests with different types of soils are given. It has been established that microclimatic changes take place in sites of ticks development. The draining favours the improvement of ecological conditions of the development of ticks. In drained parts of the forest the survival of preimaginal phases is higher than that in drained ones.

New species of feather mites (Analgoidea) from Passeriform birds in Kirgizia. P. 47-56.
Eight species of feather mites from ten species of Passeriform birds were collected in Kirgizia. Four new are described: Analges microaspis sp.n. from Phoenicurus erythrogaster (Guld.), A. paricola sp. n. from Parus cyanus Pall., Pteronyssoides ottuki sp. n. from Delichon urbica (L.), Xolalges alexeevi sp. n. from Riparia riparia (L.).The location of mites on host's body is reported for all collected species.

Monordotaenia alopexi sp. n. (Cestoda, Taeniidae), a cestode from polar fox of Chukotka. P. 61-63.
On the basis of the material collected in Chaun tundra (NW Chukotka) a new cestode species, Monordotaenia alopexi sp. n., from the polar fox (Alopex lagopus) is described. This is the fifth taeniid species with singlerow armation of the scolex. A detail morphological description supplied with figures and differential diagnosis is given.

On the systematic position and distribution of some trematodes of the genera Dinurus and Ectenurus. P. 64-66.
In pelagic fishes from the tropical part of the Pacific and Indian Oceans there were found trematodes of Dinurus barbatus, D. breuiductus and Ectenurus lepidocybii in new hosts. An additional description of E. lepidocybii is given. It has been established that progenetic metacercariae of D. tornatus are most likely metacercariae of D. longisinus. D. selari Parukhin, 1966 is reduced to a synonym of D. scombri Yamaguti, 1934.

On the embryonal development of the oxyurid Hammerschinidtiella diesingi from the oriental cockroach. P. 66-70.
The embryonal development of Hammerschmidtiella diesingi (Thelastomatidae) from the oriental cockroach Blatta orientalis was studied. The early stages of cleavage, gastrulation and some stages of the 1st instar larva formation are described. A small size of blastomere E, the formation of unflat rhombic figure as a result of the second cleavage and the formation of blastomere MSt, which unites anlages of stomodeum and mesoderm, are characteristic features of the development of H. diesingi. According to the last character the development of H. diesingi resembles that of Ascaridae and differs from that of rhabditids. An egg of H. diesingi has an oper culum and microscopic thickenings on the surface. Eggs of such shape occur in nematodes of the families Oxyuridae and Thelastomatidae.

The effect of a long stay in the tick Ornithodores tartakovskyi (Argasidae) upon the plague agent. P. 75-76.
It has been established that a long stay in ticks during 1138 days does not affect the viability of the plague microbe and its biological properties.
in Russian
The effect of repeated infecting feedings with plague microbe upon the block formatoin in fleas. P. 77-79.
Repeated infections of X. cheopis with plague resulted in the increase in the number of blocked fleas. Daily feedings were noted to favour an earlier appearance of blocked fleas.

Materials on the fauna and ecology of bloodsucking mosquitoes (Culicidae) in the northern taiga of the Sverdlovsk region. P. 80-83.
20 species of blood-sucking mosquitoes were recorded from the northern taiga of Ural (the northern part of the Sverdlovsk region): 15 species of the genus Aedes, 2 species of Culex, 2 species of Culiseta and 1 species of Anopheles. Larvae of Aedes occur in masse in small temporary water bodies. In summer after rains larvae of Culiseta and Culex as well as some species of Aedes appear. In May overhibernated Culiseta alaskaensis, C. bergrothi and An. maculipennis begin the flight of mosquitoes. The peak of the number and specific variety of attacking mosquitoes was recorded in July; in August their activity started to decrease. Aedes communis and A. punctor are mass species, A. excrucians, A . hexodontus and C. bergrothi are rather abundant, the other species are small in number or rare.
