Haemaphysalis (allophysalis) danieli, sp. n. (ixodoidea: ixodidae), female and tentatively associated immature stages from high mountains of northern Pakistan and Afghanistan.

Haemaphysalis (Allophysalis) danieli sp. n. is described from a female taken from alpine vegetation in Swat, Pakistan. Fifty-one nymphal and larval ticks tentatively associated with this taxon are from hamsters, field mice, voles, and marmots (Rodentia), Cricetulus migratorius, Apodemus flavicollis, alticola roylei, and Marmota caudata, and from pikas (Lagomorpha), Ochotona roylei, in Gilgit and Hazara districts of Pakistan and in Badakhashan Province of Afghanistan. Collecting localities are in the western Himalayan mountain complex between 2,310 and 4,000 m altitude and between 35degrees08' and 36degrees23' N and 71degrees51' and 74degrees02' E. This species is most closely related to the mountain-inhabiting H. (A9Y pospelovashtromae Hoogstraal of southern USSR and Mongolia and H. (A.) garhwalensis Dhanda and Bhat of northern India and Nepal.

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.
