The Karoo Paralysis tick, Ixodes rubicundus Neumann (Acari: Ixodidae), is a semi-voltine ixodid that survives stressful environmental conditions using morphogenetic diapause (eggs and engorged nymphs) and desiccation resistance. Both photoperiod and

Secretions of the tick salivary glands are essential to the successful completion of the prolonged feeding of these ectoparasites as well as the conduit by which most tick-borne pathogens are transmitted to the host. In ixodid ticks the salivary glan

This paper records the identities of 558 ixodid ticks feeding on 194 humans in South Africa. These ticks belonged to 20 species in six genera and those most frequently encountered were AmblYomma hebraeum, Haemaphysalis leachi, Hyalomma marginatum ruf

Viral antigen was detected in the cytoplasm and in associated membranes of salivary gland acinus cells by indirect immunofluorescence and immunoperoxidase staining. Viral ribonucleoproteins (indicated histochemically by presence of pyroninophilic gra

The extracellular fluid volume (inulin space) of salivary glands obtained from rapidly engorging females of the lone star tick, Amblyomma americanum (L.), incubated for 30 min with a Ringer-saline containing 10−5 M adrenaline, was almost twice that

Five methods commonly advocated for tick removal from a human or domestic animal were evaluated. The application of petroleum jelly, fingernail polish, 70% isopropyl alcohol, or a hot kitchen match failed to induce detachment of adult American dog ti

Catecholamine-stimulated salivary fluid secretion (in vitro) by ixodid ticks is reduced by deletion or lowering the concentration of exogenous bathing medium Ca++. The Ca++ antagonist, verapamil, reversibly inhibits dopamine-stimulated secretion. Ion
