Life cycle and postembryonal development of the cestode Hymenolepis horrida (Cyclophyllidaea: Hymenolepididae). P. 467-471.
In experimentally infected collembolas Hypogastrura tullbergi Schaff, Onychiurus octopunctatus (Tullberg, 1876) and O. flavorufulus Martynova, 1976 the postembryonal development of Hymenolepis horrida (Linstow, 1901) is completed for the period of 10 days at 25° C. Mature cestode is formed in small intestine of Microtus subarvalis (Meyer et al.t 1972) and Lagurus lagurus Pall. in 11 days after the infection. The larva morphogenesis and some aspects of host-parasite relations during the development in the intermediate host are under consideration.

On the developmental cycle of Tanaisia zarudnyi (Trematoda: Eucotylidae). P. 472-476.
In Alma-Ata State Reserve (Zailijsky Alatau) nearly 1 per cent of land mollusks Succinea altaica evoluta were found to be infected with larvae of Tanaisia zarudnyi. Two adults were obtained experimentally from the chick's ureters. Daughter sporocysts, cercariae, metacercariae and adult are described. The members of the species are characterized by a shortened life cycle. Land mollusks serve as the first and second intermediate hosts.

Some reproductive peculiarities of microbes in fleas Xenopsylla cheopis (Siphonaptera) at the parenteral infection. P. 477-481.
Being inoculated parenterally various microbes cause in fleas X. cheopis a stable infection which, as a rule, is preserved in experimental insects to the end of life. Reproducing intensively Listeria monocytogenes and Salmonella typhimurium caused the death of all ectoparasites in 3 to 5 days. The increase in abundance of Escherichia coli, Yersinia pseudotuberculosis, Y. enterocolitica and vaccine strains of Y. pestis "EV" and Francisella tularensis went on gradually and infected fleas lived up to 15—20 and more days.

Alternative prognostication of the abundance of fleas of the genus Xenopsylla (Siphonaptera). P. 482-485.
A possibility of alternative prognostication of the autumn abundance of fleas was shown by means of statystical analysis of prognostication tables made up on the basis of the distribution of informative factors: indices of the abundance of the great gerbil, which is the main host of fleas, weather conditions and characteristics of the populations of the fleas.

Ultrastructure of antennal sensillae of Rhodnius prolixus (Hemiptera, Reduviidae). P. 486-492.
On the antenna of the bug R. prolixus we found numerous receptors which can be classified into three categories: mechanoreceptors (sensilla chaetica), olfactory (sensillae trichodea, basiconica and caeloconica) and gustatory (sensilla trichodea) receptors. The number, size and distribution on the antenna of each type have been recorded. A description of each of these sense organs is given. Tactile hairs are present on all of the anten-nal segments while thin-walled chemoreceptors are limited to segments 3 and 4. The tactile hairs are innervated by a single bipolar sensory cells. In fine structure each dendrite reveals the following successive regions; a broad inner segment, a ciliary region, a region with neurotubules. Two types of thin-walled sensilla trichoidae differ in the structure of ther walls and internal parts. It was shown that the cuticular part of the olfactory trichoid hairs has pores; the cuticular part of the basiconic sensillae had longitudinal canals.

Changes in the physiological age and abundance of Ixodes persulcatus tick sduring the period of their activity (Ixodidae). P. 493-499.
Analysis of the regularity of seasonal changes in physiological age of adult ticks of I. persulcatus has shown that this regularity is described quite satisfactorily by the asymptotic function, by means of which age can be estimated during season for any time. Changes in the age composition of active ticks are associated with the seasonal fluctuations in their abundance. Due to this connection fluctuations in the seasonal abundance of active individuals can be foreseen and evaluated retrospectively by their age composition and conversely age by seasonal fluctuations in ticks' abundance.

Fauna and biology of mosquitoes (Culicidae) from the Charskaya hollow (the Chita district). P. 500-503.
The specific composition and the nature of domination of bloodsucking mosquitoes from the Charskaya hollow were studied. The abundance dynamics of attacking females was registered by means of Berezantzev's bell. Data were obtained on the hatching sites of mosquitoes and peculiarities of seasonal adaptation of some species in connection with the availability of various landscapes with different microclimatic conditions.

Parasitic ciliates (Peritricha: Urceolariidae) of fishes from the Aral Sea. P. 504-510.
95 fishes belonging to 11 species from the Aral Sea and low reaches of the Amu-Darja were investigated. 9 species of urceolariids of the genera Tripartiella (1), Trichodina (6) and Trichodinella (2) were found. Trichodina nigra luciopercae Lom, 1970 was first recorded from the waters of the USSR, Tripartiella (Paratrichodina) incisa Lom, 1959, Trichodina acuta Lom, 1970 from Central Asia and Trichodina domerguei (Wallengren, 1897) from the Aral Sea and low reaches of the Amu-Darja. Data on the infection rate, size and original photos of some species of urceolariids are given.

Parasite fauna of the sucker (Catostomus catostomus) from the Kolyma river. P. 511-513.
4 species of parasites, Myxobolus catostomi, M. exsulatus, Glaridacris catostomi, larvae of Raphidascaris acus from which M. exsulatus is new for science, were recorded from the Siberian sucker in the middle course of the Kolyma river. Parasite fauna of the sucker in the Kolyma basin is rather poor that is very typical to hosts spread along the distribution area edge. Analysis of ichthiological and parasitological data suggests that the sucker has penetrated Asia not later than the end of Pliocene.

Preliminary data on the horizontal and vertical movement of free swimming larvae of Dactylogyrus anchoratus (Monogenoidea, Dactylogyridae). P. 514-516.
Studies of horizontal and vertical movements of oncomiracidia of D. anchoratus under aquarium conditions at a temperature from 16 to 18° С were conducted. It has been established experimentally that larvae of D. anchoratus can rise in search of host to the height of 110 cm, which apparently is close to the maximum one. The greatest distance covered by oncomiracidia under laboratory conditions at this temperature in horizontal direction is about 2 m.

Pratylenchoides ivanovae sp. n. (Nematoda: Pratylenchidae) and key to species of the genus Pratylenchoides. P. 516-520.
Pratylenchoides ivanovae sp. n. was found in Tadjikistan (the Pamirs) near the lake Jashilkul in soil near the roots of Salix schungnanica Goerz. The new species is close to P. epacris by the stylet length and labial region structure. It differs from the latter by five lines of the lateral area which pass into four ones in the caudal portion, by the termination sculpture, excretory pore location, labial region width and coefficients b and c. Key to species of the genus Pratylenchoides is given.

The effect of bloodsucking flies on the productivity of animals of Turkmenia. P. 520-522.
Due to the attacks of bloodsucking flies in summer average daily milk yielding of one cow fall by 0.881 (16.4%) and overweight of young cattle stock fall by 109 g (29.5%) per one animal. During the experiments (from 6 a. m. to 8 p. m.) one control animal was attacked on the average by over 10000 bloodsucking Diptera. These insects disturbed the animals at night but their abundance was not taken into account.

New species of rhynonyssids of the genus Ptilonyssus s. str. (Gamasoidea, Parasitiformes) parasitic in larks. P. 522-531.
A description and figures of three new species of mites are given: Ptilonyssus schumili sp. n. from Alauda arvensis L., Ptilonyssus eremophilae sp. n. from Eremophila alpestris (L.) and Ptilonyssus diadori sp. n. from Melanocoripha yeltoniensis (Forst.). The new species are morphologically close to Ptilonyssus estrildicola Fain, 1959.

The use of exogenous 14C-glycine by sporozoites of Eimeria tenella (Sporozoa, Coccidiida) for synthesis of proteins. P. 531-533.
By means of 14C-glycine the ability of sporozoites of Eimeria tenella to synthesize proteins using amino acids from external extracellular medium was shown.

A new species of Haplosporidia, Dermocystidium erschowi sp. n., from Cyprinus carpio. P. 533-537.
A new species of parasitic Protozoa, Dermocystidium erschowi sp. n., from Cyprinus carpio is described. The species is characterized by long filamentous cysts. In subcutaneous cellulose of fishes infected with these protozoans parasitogenic nodes of fungoid form and later skin ulcers develope.
