Efficacy of Local Essential Oils Against Amblyomma Variegatum Tick from Burkina Faso

Veterinary Parasitology, 2023
The native tick Amblyomma variegatum remains one of the most important tick species affecting cattle in West Africa. This hinders animal production by negatively impacting the health and reproduction of animals infested with the tick. Given the negative consequences on production quality and environmental health, the use of chemical products for tick ...

Poor inheritance of low attractiveness for Amblyomma variegatum in cattle [PDF]

Veterinary Parasitology, 2007
Because of the high variability of cattle infestation, selective breeding has been proposed to control three-host ticks in Africa in the same way as it has been implemented to control the one-host tick Boophilus microplus in Australia. Interbreeding (divergent selection experiment) between Gudali zebu cattle was performed at the Wakwa Research Centre ...

Factors of Variation of Amblyomma variegatum Infestation on Creole Cattle in Guadeloupe [PDF]

Annals of the New York Academy of Sciences, 1996
The level of infestation of "Creole" beef cattle of Guadeloupe by the tick Amblyomma variegatum was recorded during a long-term survey in an experimental farm: 61 steers and 83 cows were distributed in different lots according to sex and management. They grazed continuously either on irrigated Digitaria decumbens pastures or on dry native savannahs ...

Egg laying patterns of Amblyomma cohaerens (Donitz,1909) and Amblyomma variegatum(Fabricius,1794).

Bulletin of Animal Health and Production in Africa, 2009
A study was carried out to determine the egg-laying patterns of Amblyomma cohaerens and Amblyomma variegatum. Twenty individual engorged ticks of each species, obtained from cattle were used in this study. Each tick was reared in a petridish at room temperature (25±30 C) and relative humidity of 70 ± 5% until the end of oviposition.

Characterization of protective antigens from the midgut of Amblyomma variegatum ticks

Experimental & Applied Acarology, 2002
Separation of midgut membrane proteins from the tick, Ambylomma variegatum, using a nonionic detergent (Triton X-114), resulted in two protein fractions, namely DET (detergent) and AQ (aqueous). In immunoblotting analysis with polyclonal antibodies against these fractions, 4 proteins (Mr approximately 27,000, 67,000, 86,000 and 95,000,) and 2 proteins (

Attachment kinetics of the adult tick Amblyomma variegatum to cattle

Medical and Veterinary Entomology, 2006
Abstract At the beginning of the 1999 rainy season, three traditional cattle herds were monitored for 48 days while grazing in the bushy savannah of southwestern Burkina Faso. Cattle in each herd were caught on several occasions each day and the attached ticks were counted. This confirmed that

Landsat-TM identification of Amblyomma variegatum (Acari: Ixodidae) Habitats in Guadeloupe

Remote Sensing of Environment, 1992
Abstract The objective of this study in 1986–1987 was to determine whether it was possible to remotely identify the specific habitat or habitats of the African bont tick, Amblyomma variegatum , using Landsat-TM imagery data. An unsupervised classification of the April 1986 image was carried out using LAS KMEANS and SPCSRT.

Invasion of West African cattle by the tick Amblyomma variegatum

Medical and Veterinary Entomology, 2000
Summary Studies in Cameroon and Burkina Faso examined the invasion process of cattle by adult Amblyomma variegatum Fabricius (Acari: Ixodidae) ticks. Nearly all the ticks picked up in the pasture during grazing were found on the limb ends, near the hooves, where they ...

Rickettsia africae in Amblyomma variegatum and Domestic Ruminants on Eight Caribbean Islands

Journal of Parasitology, 2010
We used PCRs with omp A primers to determine if spotted fever group rickettsiae occurred in Amblyomma variegatum from 6 Caribbean islands. Positive amplicons were obtained from ticks from the U.S. Virgin Islands (9/18; 50%), Dominica (39/171; 30%), Montserrat (2/5; 40%), Nevis (17/34; 50%), St. Kitts (46/227; 20%), and St. Lucia (1/14; 7%).

Amblyomma variegatum Ticks and the Occurrence of Bovine Streptothricosis in Antigua

Journal of Veterinary Medicine, Series B, 1989
SummaryThe association between the occurrence of Amblyomma variegatum ticks and streptothricosis was studied on the Caribbean island of Antigua. The prevalence of streptothricosis was higher on animals having A. variegatum ticks compared to that of animals not infested with A. variegatum ticks.
