This study reports the results of a comparative test of identification of ticks occurring in Western Europe and Northern Africa. A total of 14 laboratories were voluntarily enrolled in the test. Each participant received between 22 and 25 specimens of adult and nymphal ticks of 11 species: Dermacentor marginatus, D. reticulatus, Haemaphysalis punctata, Hyalomma lusitanicum, Hy. marginatum, Ixod...
ticks are considered to be the main vectors for transmission of various diseases to animals and human. the present faunistic study aimed to determine species belonging to Ixodidae ticks, infesting cattle of Khoozestan province, south-west of Iran. Totally 1000 ticks were collected randomly from cattle from 9 locations in five geographical regions between January to September 2011, and were iden...
In 1994 a batch of apparently healthy goats was selected for intended export to the USA from a heartwater-free and vector tick-free region of South Africa. The animals were tested serologically for heartwater, using either or both an IFA and an ELISA test, and 52% were found to be serologically positive. A PCR assay based on Ehrlichia ruminantium 16S gene sequences gave positive results for 54%...
objectives: ticks are vectors of several diseases, of which many are zoonosis transmissible to humans. the use of tephrosia leafs’ extract as a low cost acaricide is spreading among farmers in central kenya. materials and methods: the present study’s aim is to inventory endogenous control methods against dogs’ ticks among which rhipicephalus sanguineus, in the municipality of abomey-calavi. fro...
Knockdown and persistence efficacies of a pour-on containing Amitraz 1% and Cypermethrin 1% and a spray dip containing 12.5% Amitraz were compared. Knock-down and persistence efficacies of the Amitraz spray dip against Rhipicephalus (Boophilus) decoloratus and Amblyomma hebraeum were significantly higher for the duration of the trial than those of the pour-on. In the case of Rhipicephalus apped...
This study was conducted from September 2011 to May 2012 in Borana pastoral area with the objectives of determining the distribution and relative abundance of Ixodid ticks on cattle in relation to short rain and major dry seasons, cattle age and sex. A total of 8,912 adult ticks belonging to genera of Rhipicephalus, Amblyomma, Boophilus and Hyalomma were collected from 768 indigenous cattle. Rh...
A study was conducted to compare the species of adult ixodid ticks on Friesian and Bonsmara cattle and their seasonal dynamics. Between five and ten animals of each breed were kept on natural False Upper Karoo vegetation, typical of the south-western Free State. Between May 1990 and October 1991, the animals were examined once or twice a month for the presence of adult ticks which were removed,...
The study aimed to assess the long-term population dynamics of questing Rhipicephalus appendiculatus and Rhipicephalus zambeziensis in two landscape zones of the Kruger National Park (KNP). Ticks were collected by dragging the vegetation monthly in three habitats (grassland, woodland and gully) at two sites in the KNP (Nhlowa Road and Skukuza) from August 1988 to March 2002. Larvae were the mos...
BACKGROUND Ticks are important vectors of human and animal pathogens. They are considered as main vectors for transmission of many viral, bacterial, rickettsial and parasitical pathogens. The aim of the present study was to find out species diversity of ticks, which infested the domestic ruminants in Zabol County, Eastern Iran in 2012. METHODS Ticks were selected randomly from sheep, goats, c...
