in RussianThe main achievements in the study of immunology of helminthoses. P. 115-125.
Analysis of available literature has shown a considerable progress in the research of the immunology of helminthoses during recent years. In the Soviet Union the study of this problem is carried out, though to a lesser extent, in the same directions as in other countries.
They are as follows:
1. study of manifestation, degree of intensity and mechanisms of immunity;
2. study of antigenic structure of helminths as a basis for a purposeful search of methods of cleaning antigenes from ballast matters and criterium of taxonomy;
3. elaboration of methods for immunodiagnostics of helminthoses;
4. use of immunological methods for a study of epidemiology of helminthoses (seroepidemiology);
5. study of immunopathology.
in RussianLong-term use of genetic methods of control of bloodsucking Diptera, vectors of the diseases of man. P. 126-135.
The paper presents genetic methods of control of bloodsucking Diptera, mosquitoes. The perspective of the use of various control methods, first of all those tested under field conditions in application for bloodsuckers which are of medical importance throughout the USSR, is regarded. The opinion is suggested that the method of X-ray sterilization uf pupae taken from nature and the translocation and chemical sterilization methods can be successfully used for the control of An. m. sacharovi, malaria vectors resistant to DDT. The male sterilization method and the use of males cytoplasmatically incompatible with translocations are suggested for the control of synanthropic populations of С. pipiens.
in RussianA distant orientation of Ixodes persulcatus to the attractant factors of the prey. P. 136-141.
The laboratory and field tests have shown that the odour is the main factor which activates ticks (Ixodes persulcatus) attraction to the host. Ticks have a sensation of a man on 15 metres distance; the number of activated ticks increases with the distance to the host and depends on the wind direction. The infrared radiation source excites only a short time activation of the ticks on 0.5—1.0 metres distance. Mechanic and sound stimulations were found to be uneffective for the ticks in the experiment.
in RussianDensity and distribution of pasture ixodid ticks in Central Sikhote-Alin. P. 142-147.
Data are given on the density of active ticks in different landscapes in the central part of Sikhote-Alin. The character of the ticks distribution (regular, even, contagious) in dependence on the relief and vegetation is analysed.
in RussianOn polytypical species of mosquitoes. I. Anopheles hyrcasus (Pallas, 1771). P. 146-153.
An. hyrcanus differs from close An. sinensis Wied. from south-eastern Asia in the following characters: colour of palps and wings, scales of hind abdominal sternites (Table 1). Populations of An. hyrcanus from various regions of the Soviet Union display great variability of systematic characters. The comparison of specimens from the western and eastern parts of the distribution area has shown that the difference between them is negligible and unstable (Table 2). We have no reason to assign An. hyrcanus from the Far East of the USSR to a distinct subspecies.
in RussianSusceptibility of laboratory animals to Trichinella from synanthropic and natural nidi of the North Caucasus. P. 154-157.
Laboratory animals were infected with larvae of four species of Trichinella. The tests have shown that T. pseudospiralis is highly infectious for golden hamsters and guinea pigs. Rats are relatively resistant to T. pseudospiralis but highly susceptible to T. spiralis. T. nelsoni turned out to be little infectious to rodents which were used in the experiment. T. nativa is little infectious for rats but more infectious for golden hamsters and guinea pigs as compared to T. nelsoni.
in RussianOn the developmental periods and adaptation of parthenites of Eurytrema pancreaticum (Dicrocoelidae, Trematoda) to environmental conditions. P. 158-162.
Data are given on the developmental periods of parthenites of E. pancreaticum (Janson, 1889) from the Far East of the USSR. The growth and formation of parthenites were found to take place from May to October and to coincide with the active period of the intermediate host's life cycle. With the decrease of autumn temperatures to 8° the growth of parthenites slows down and ceases sompletely in October. The pause in the development of parthenites from October to April causes longer developmental periods of parthenites as compared to those in the regions of tropical and subtropical climate. Under laboratory conditions at a temperature of 8 to 22° the development of parthenites proceeds without any intervals within 6.5 months.
in RussianThe life cycles of Aploparaksis birulai Linstow, 1905 and Aploparaksis brachyphallos (Krabbe, 1869). P. 163-169.
Larvae of A. birulai from Lumbriculus variegatus and A. brachyphallos from Stylodrilus sp. from the Chauna lowland (Chukotka) are described. The species belonging of the larvae was proved experimentally. It was shown that Cysticercus sp. Hrabe, 1958 is a larvacyst of A. birulai. For larvacysts of A. birulai type the name "floricerk" was suggested and for those of A. brachyphallos type — the name "tailed diplocyst". It is noted that A. uelcal Spassky et Jurpalova, 1968 is a synonym of A. brachyphallos (Krabbe, 1869) nec A. brachyphallos sensu Davies, 1938.
in RussianMorphological peculiarities and certain biological problems of the genus Apiosoma members (Ciliata, Peritricha) from the young of predatory fishes. P. 170-177.
13 species of Apiosoma were recorded from the young of Esox lucius, Lota lota and Perca fluviatilis. 7 species were reported from Lota lota, 9 species — from Esox lucius and 6 species — from Perca fluviatilis. Apiosomes were found mainly on the body surface and fins of fishes and move seldom on their gills. Under changing conditions the transition of parasites from one organ to another is possible. Great morphological variability of Apiosoma is reflected in variability of shape and size of the body and mutual arrangement of micro — and macronucleus. The solution of the variability problem is necessary for the classification of the genus Apiosoma. A new species, Apiosoma lotae, and subspecies, Apiosoma piscicola percae, are described.
in RussianChanges in the white blood contents of the carp at the infection with Dactylogyrus extensus (Monogenoidea, Dactylogyridae) in the light of a new classification of formed elements. P. 178-182.
The paper presents new data on the effect of Dactylogyrus extensus on the blood of the carp. The data have become available due to a new classification of formed elements worked out by N.T. Ivanova. One of characteristic features of dactylogyrosis is eosinophilia. Polychromatophil anaemia and anisocytosis were recorded as well.
in RussianPeritrophic membrane of the 2-nd type in the females of the genus Aedes. P. 183-184.
In the females of bloodsucking mosquitoes of the genus Aedes there was recognised a secretory activity of the cells of the external wall of the cardial portion of the intestine. The secretion excreted according to the macroapocrine type forms in the cardial cavity a peritrophic membrane of the 2-nd type. A difference in the development rate of the membrane in the species studied was noted.
in RussianRevision of some Holarctic species and subspecies of the genus Culiseta Felt. I. Culiseta (Culiseta) kanayamensis Yamada as a synonym of С. (C.) bergrothi Edwards. P. 185-187.
The arguments are given in favour of the identity of two mosquito species, Culiseta bergrothi Edwards, 1921 and C. kanayamensis Yamada, 1932; the latter name should be considered as a synonym of the former according to the author's priority. A map of the geographic distribution of C. bergrothi (=C. kanayamensis) is given in which the association of this mosquito with the taiga zone of the Palaearctic is shown.
in RussianGonotrophic cycle of Leptoconops borealis (Diptera, Ceratopogonidae). P. 188-191.
Data are given concerning the gonotrophic cycle in fully engorged specimens of Leptoconops borealis, a mass blood sucker from the coast of the sea of Azov. In fully engorged females the repetition of gonotrophic cycles and degeneration of ovaries take place under the effect of Mermitoidea parasitism.
in RussianA new species of the mites, Haemogamasus bujakovi sp. n. (Acarina, Gamasodoidea). P. 191-193.
The female of the new species Haemogamasus bujakovi sp. n. is described from the Tungokochen region of the Chita district. Two females of the mite were taken from Apodemus speciosus and one from Clethrionomys rutilus.
