Feeding of Dermacentor reticulatus (Fabr.) females depending on their age, origins and biotope of survival.

In Dermacentor reticulatus (Fabr., 1794) females originating from Slovakia and Poland the duration of feeding on host and its successful outcome depending on the age, origins of ticks and biotope of their survival was studied. In specimens older than a half year no influence of these factors on the duration of feeding was demonstrated. With increasing age the ability of full engorgement did no diminish. The data obtained indicate the possibility that a higher percentage of females of equal age engorge from the forest biotope than from the meadow biotope.

The amino acid sequence of cytochrome c' from the purple sulphur bacterium Chromatium vinosum.

An amino acid sequence is proposed for the cytochrome c' from the photosynthetic purple sulphur bacterium Chromatium vinosum strain D. It is single polypeptide chain of 131 residues, with haem-attachment cysteine residues at positions 121 and 124. The results discredit an earlier report [Dus, Bartsch & Kamen (1962) J. Biol. Chem 237, 3083--3093] of a di-haem peptide sequence from this protein. The sequence belongs to the same class as the published Alcaligenes and Rhodospirillum rubrum cytochrome c' squences, but the resemblance is not close. Detailed evidence for the amino acid sequence of the protein has been deposited as Supplementary Publication SUP 50,093 (15 pp.) at the British Library Lending Division, Boston Spa, Wetherby, West Yorkshire LS23 7BQ, U.K., from whom copies may be obtained on the terms given in Biochem. J. (1978) 169, 5.

Ixodid ticks of Barun Glacier region (the Nepal Himalaya).

During the 3rd Czechoslovak mountaineering expedition to the Himalaya in the spring 1973 ticks of the family Ixodidae were collected from small mammals and additionally from pastured sheep, and humans. The tick material represented the following species: Ixodes (P.) ovatus Neumann, 1899, Ixodes (I.) acutitarsus (Karsch, 1880) and Haemaphysalis (A.) aponommoides Warburton, 1921. Ecological and zoogeographical characteristics of the ticks found are given and their potential medical importance is discussed.

Isolation of Bhanja virus from ticks of the genus Haemaphysalis in southeast Bulgaria and presence of antibodies in pastured sheep.

Bhanja virus was isolated from ticks of the genus Haemaphysalis (H. punctata and H. sulcata) collected from sheep pastured in the surroundings of Akhtopol in southeast Bulgaria, and simultaneously blood sera of 58 sheep were investigated in plaque-reduction neutralization test with B lranja arbovirus. All sera contained antibodies to this virus in titres from 1:32 to 1:4096 (geometrical mean titre 1:494). The district of Akhtopol proved to be a natural focus of Bhanja virus.

Microclimate as a determining element in the distribution of ticks and their development cycles.

The paper deals with the problem of interrelationship between macroclimate of the region, mesoclimate of the biotope studied and microclimate of the tick niches proper, necessary for the research of tick ecology. New methods for the solution of microclimatological studies are proposed and the relationship between macro-and mesoclimate, or that between temperature in the tick cage and environment, is formulated. In choosing optimal intervals of data acquisition a two-hour interval (every even hour of the day) has proved to be the most suitable.

Mesostigmatid mites of small mammals from the Hindu Kush (Afghanistan).

During the First Czechoslovak mountaineering expedition to the Hindu Kush (1965) a material of mesostigmatid mites was collected from small mammals, yielding 16 species. Due to the fact that it is the first collection of these parasites studied in Afghanistan, a zoogeographic analysis, altitudinal stratification and epidemiological estimation are appended.

Possibilities of persistence in new biotopes of ticks imported by birds.

Survival and development of 6 tick species (Hyalomma anatolicum, Rhipicephalus sanguineus, Haemaphysalis punctata, Dermacentor marginatus, D. reticulatus and Ixodes ricinus) were studied in 3 groups differing in the range of distribution with respect to the place of importation, as a model for the knowledge of their possible inclusion in the new local biocenosis during transportation by natural hosts.

Development and survival of the tick Hyalomma dromedarii Koch under laboratory conditions.

Developmental cycle of the tick Hyalomma dromedarii as influenced by changes of temperature and humidity was studied under laboratory conditions. Feeding and metamorphosis of developmental stages were observed under standard laboratory conditions, the metamorphosis was traced at exposure to temperature of 28 degrees C, 80% RH to alternating diurnal climate 40 degrees C, 25% RH and 20 degrees C, 80% RH and alternating humidity of 40/100% and 60/100% RH at a constant temperature 30 degrees C.

Influence of microclimate on the life cycle of the common tick Ixodes ricinus (L.) in an open area in comparison with forest habitats.

Under conditions of the South-Moravian region of Pannonian climate (Valtice near Breclav), the life cycle of the common tick Ixodes ricinus (L.) was studied and a continous recording of main elements of microclimate (temperature and humidity) was carried out in an open grassy area. Simultaneously the process of hibernation was studied in four soil layers (surface, depths of 10, 20 and 30 cm). Observations were assessed by mathematiccal-statistical tests and compared with the results obtained by the same methods in the forest biotope (tipe of thermophilic oak forest)and in the ecotone of forest margin (Daniel et al. 1976). The ticks are able to complete the developmental cycle also in the open grassy areas, where during the vegetation period the development proceeds more quickly than in the forest but with considerably higher losses. In the discussion the conclusions are compared with literary data from other parts of Czechoslovakia.

Influence of microclimate on the life cycle of the common tick Ixodes ricinus (L.) in thermophilic oak forest.

Under conditions of the South Moravian thermophilic oak forest (Valtice near Breclav), the life cycle of the common tick Ixodes ricinus was studied by continuous recording of main elements of microclimate (temperature and humidity) in three different biotopes: forest, margin of the forest and meadow. Simultaneously conditions and the process of tick hibernation were studied in four soil layers (surface, depths of 10, 20 and 30 cm). Observations made in the winter and vegetation periods were assessed by mathematical-statistical tests. Results obtained in the forest biotope and at its margin are presented in this paper; results from the meadow biotope will be published separately.

Rhabdochona minima sp. n. (Nematoda: Spiruroidea) from the loach, Noemacheilus inglisi (Hora), of Nepal.

A new nematode species, Rhabdochona minima sp.n., is described from the intestine of Noemacheilus inglisi (HORA) OF Nepal (River Ganges drainage system). Characteristics features of this species (only males were found) are the small size of body, size and type of spicules, shape of tail and arrangement of caudal papillae. On the basis of its morphology, R. minima sp.n. belongs to the subgenus Globochona sensu Moravec, 1975. The species Rhabdochona cavasius Rehana et Bilqees, 1973 is considered to be a synonym of R. mazedi Prassad et Sahay, 1965.

To the knowledge of fauna of synanthropic flies of the Nepal Himalya.

A material of flies collected in two localities (altitude of 3900 and 4500 m) in the Barun Khola Valley (East Nepal) was studied, representing the early spring aspect of the species composition of flies. Of the total number of 2309 fly specimens 99.3% represented two species of the genus Paregle (P. aterrima, P. sp.); both are autochthonous high altitude hemisynanthrophic forms. The remainining 0.7% represent 9 species, most of which are more or less eurytopic species of palearctic or holoarctic distribution (Calliphora vicina, C. vomitoria, Meoneura flavifacies, Scatophaga stercoraria, Hydrotea hirticeps, Orthellia caesarian, Paregle danieli, Anthomyiidae g. sp. 1, g. sp. 2).
