Photoperiodic response in the soft tick, Ornithodoros turicata
International Journal for Parasitology, 1996The effects of photoperiod on the feeding, development and quiescent behavior of the burrow-dwelling soft tick, Ornithodoros turicata (Dugès) were investigated. Ticks were assigned randomly to either continuous darkness (DD), a short-day photoperiod (L:D 10:14), a long-day photoperiod (L:D 14:10) or constant light (LL).

On the presence of spermine in the spermatophore of a soft tick
Journal of Insect Physiology, 1980Abstract In the spermatophore of soft ticks spermine has been found in the semen, as well as in the proteinous sacs, at much higher concentration. The spermine can be seen under the microscope to form needle-like crystals which are shown to be spermine phosphate. This is the first time that spermine has been reported in the Arthropoda.

An overview on Sardinia’s soft ticks (Ixodida: Argasidae)
Experimental and Applied Acarology, 2016Knowledge about soft ticks (Ixodida: Argasidae) in Sardinia is incomplete and distribution data need to be updated. This work studies soft ticks on the island focusing on two species, Argas reflexus and Ornithodoros maritimus, both recently recorded. A total number of 12 specimens of these species of interest were collected between 2004 and 2015.

Quantification of ASFV DNA and RNA in Ornithodoros Soft Ticks
2022Molecular biology methods are highly sensitive to detect the genome of pathogens and to study their biology. Polymerase chain reaction (PCR) and reverse transcription followed by a polymerase chain reaction (RT-PCR) permit the detection of the presence and the replication of African swine fever virus in soft ticks.

An Overview of Hard and Soft Ticks and Their Control Methods
2021Ticks are important ectoparasites of livestock in tropical and sub-tropical countries. They are responsible for the enormous economic losses both through the direct effects of blood sucking and indirectly as vectors of disease pathogens and toxins. Morphologically, ticks are classified into two families known as Ixodidae (hard ticks) and Argasidae ...

Respiratory metabolism of the soft tick, Ornithodoros turicata (Dug�s)
Experimental and Applied Acarology, 1995The rate of oxygen consumption was investigated in fed larval, nymphal and adult Ornithodoros turicata ticks and in starved nymphal and adult ticks. Oxygen consumption rate of fed adult ticks increased with increasing temperature. The metabolic rate of adult ticks was affected by starvation whereby starved adult ticks showed a significantly lower ...

Biological control studies of soft and hard ticks in Egypt
Parasitology Research, 1997The potential activity of three varieties of Bacillus thuringiensis (kurstaki, israeliensis, and thuringiensis) against the soft tick Argas persicus and the hard tick Hyalomma dromedarii was investigated. Soft ticks succumbed within a period ranging from 36 h to 5 days and hard ticks died at between 48 h and 10 days posttreatment, depending on the dose.

A New Ligation Technique for Soft Ticks (Acari: Argasidae)
Journal of Medical Entomology, 1988A new technique is described for the ligation of soft ticks using standard office staples. The technique was applied to Ornithodoros parkeri . The method is simple and easy; it results in complete separation of the tick body and causes low mortality.

Techniques for Mass Rearing Soft Ticks (Acari: Argasidae)1
Journal of Medical Entomology, 1986Techniques are described for efficiently producing thousands of soft ticks for experimental use. A general method is described for each of the following feeding categories: (1) small species with short-term-feeding larvae ( Ornithodoros turicata, O. parkeri, O. erraticus ); (2) small species with long-term-feeding larvae ( O. puertoricensis, O. dugesi )

Journal of Invertebrate Pathology, 2006
A yellow-pigmented Gram-negative bacterium, Chryseobacterium indologenes, was found in the gut contents of about 65% of soft ticks Ornithodoros moubata from a perishing laboratory colony. The isolated putative pathogen, C. indologenes, was susceptible to cotrimoxazol and addition of this antibiotic (Biseptol 480) to the blood meal significantly ...
