Bionomics and health importance of fowl tick Argas (Persicargas) persicus (Oken, 1818) (Ixodoidea: ARgasidae).

The fowl tick Argas (Persicargas) persicus occurs in warm areas of Slovakia, where its distribution is limited by the 650-700 mm annual average isohyet and the +8 degrees C annual average isotherm. In Slovakia, larvae hatch from spring to autumn, and nymphal and adult moultings occur chiefly in July and August. Larvae feed for four days, nymphs and adults for less than one hour. The tick develops and reproduces during the warm season in the wild but throughout the year under favourable laboratory conditions in which the life cycle requires 17 months.

Isolation of Tettnang virus from ticks, mosquitoes and small rodents.

Seven strains of Tettnang virus were isolated in Czechoslovakia: 3 from Ixodes ricinus tick nymphs, males and females, one from Dermacentor reticulatus tick females, one from Aedes cantans mosquitoes and two strains from the brains of Clethrionomys glareolus and Apodemus flavicollis small rodents.

Identification of anticoagulant activities in salivary gland extracts of four horsefly species (Diptera, tabanidae).

Anticoagulant activities against the extrinsic and intrinsic coagulation pathways were identified in salivary gland extracts (SGE) prepared from four tabanids (Hybomitra muehlfeldi, Tabanus autumnalis, Haematopota pluvialis, Heptatoma pellucens). All extracts prolonged human plasma clotting time in a dose-dependent manner and inhibited thrombin activity in the chromogenic substrate assay. Horsefly SGE did not inhibit factor Xa. Partial purification of SGE proteins using reversed-phase high-performance liquid chromatography revealed species-specific differences in the elution profiles and range of fractions with anticoagulant activities.

Tick-borne encephalitis virus activity in Styria, Austria.

From 3,404 Ixodes ricinus ticks collected in 12 localities of Styria, Austria in 1990, 15 tick-borne encephalitis (TBE) virus isolates were recovered. Minimal field infection rate reached 4.4 virus containing ticks out of 1,000 collected ticks. Five isolates of TBE virus were obtained from target organs of Apodemus flavicollis trapped in locality Wagnitz. In a serosurvey based on virus neutralizing antibodies high prevalence of TBE virus was demonstrated in A. flavicollis (47.9%) and Clethrionomys glareolus (29.4%). These rodents formed 57.8% and 41.0% of 83 trapped small mammals.
