The effect of the fungus Metarhizium anisopliae Ma14 strain, D-limonene, and cypermethrin, alone and combined, on the mortality of Rhipicephalus sanguineus Latreille larvae was evaluated. Eight separate groups with 25 tick larvae were inoculated with the fungus, cypermethrin, and D-limonene, and four groups were used as untreated controls. The groups were inoculated with serial dilutions of eac...
The Rhipicephalus sanguineus (Latreille) complex (Acari:Ixodidae) is composed of species with intra- and interspecific morphological variation that make their diagnosis difficult. In the present study, male specimens of the R. sanguineus complex were collected from dogs in six districts of three regions of Brazil and submitted to molecular and scanning electron microscopy (SEM) analyses. Analys...
Canine hepatozoonosis, caused by Hepatozoon canis, is transmitted by the ingestion of brown dog tick, Rhipicephalus sanguineus. In the present study R. sanguineus ticks (n=60) collected from dogs presented at Small Animal Clinics, Teaching Veterinary Clinical Complex, GADVASU, Ludhiana, Punjab, India were screened by PCR based assay for the detection of H. canis specific 18S ribosomal RNA gene ...
The objective of the study was to assess the speed of kill of a single topical treatment with a combination of fipronil and permethrin (Frontline Tri-Act(®)/Frontect(®)) against experimental infestations of Ixodes ricinus and Rhipicephalus sanguineus ticks on dogs. In this parallel group designed, randomised, single centre, controlled efficacy study, 16 healthy adult dogs were allocated to two ...
Previous studies have demonstrated that Thogoto virus is transmitted from infected to uninfected ticks when co-feeding on uninfected guinea-pigs, even though the guinea-pigs do not develop a detectable viraemia. Furthermore, tick to tick transmission is potentiated by factors associated with the salivary glands of ticks (saliva activated transmission). The vector efficiency of 2 ixodid tick spe...
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...
We reported the hymenopteran fauna (except Formicidae) in a floodable area South Pantanal, Mato Grosso do Sul, Brazil. The study was conducted riparian forest of Miranda river, located Passo Lontra region, Corumbá. collection occurred dry season August 2016 using different capture methods. A total 137 individuals distributed 18 families, 43 genera, and 64 morphospecies (10 nominal) were collect...
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...
