Six genera and 27 species of hard ticks (Ixodidae) currently are recognized in the United States east of the Mississippi River as follows: Amblyomma (4 species), Boophilus (1), Dermacentor (3), Haemaphysalis (2), Ixodes (16), and Rhipicephalus (1). We present a diagrammatic couplet key to the adults of the six genera and 27 species of Ixodidae found in the eastern portion of the United States.

Eighty-three species of ixodid ticks, as well as several entities that have yet to be described, occur in the Republic of South Africa plus the 4 independent states lying within its borders (Bophuthatswana, Venda, Transkei and Ciskei) and in Namibia, Botswana, Lesotho and Swaziland. They belong to the following genera: Amblyomma (8 spp.); Aponomma (3 spp.); Boophilus (2 spp.); Cosmiomma (1 sp.)...

Sequences from the Anaplasma phagocytophilum 16S rRNA gene were detected in 5 ticks representing 3 species (Hyalomma marginatum, Rhipicephalus turanicus, and Boophilus kohlsi) collected from roe deer (Capreolus capreolus) in Mount Carmel, Israel. The sequences were all identical to those of Ap-variant 1 strain.

Findings of epimastigotes forms of a tripanosomatide is reported in the hemolymph of the cattle tick Boophilus microplus in the state of Rio Grande do Sul, southern Brazil. Morphological evidences suggest they are similar to Trypanosoma theileri, a species described as non pathogenic to cattle, and usually transmitted by tabanids.

The objective of this study was to compare the presence on goats and cattle of adult ticks that usually infest cattle. To this end ticks collected from sets of five goats were compared with those collected from sets of five cattle at 72 communal dip-tanks in the eastern region of the Eastern Cape Province. Amblyomma hebraeum was present on goats at 25 and on cattle at 39 dip-tanks, and a total ...

A 12-month study was conducted in 4 communal grazing areas in the Bushbuckridge region, Limpopo Province, South Africa. The main objective was to investigate the impact of reduced acaricide application on endemic stability to bovine babesiosis (Babesia bigemina and Babesia bovis) and anaplasmosis (Anaplasma marginale) in the local cattle population. To this end 60 cattle in each communal grazin...

BACKGROUND The aim of this study was to investigate the 'acaricidal effect' of Zataria multiflora and Artemisia annua essential oils on Rhipicephalus (Boophilus) annulatus. METHODS This study was carried out in 2009 in the Laboratory of Parasitology of the Faculty of Veterinary Medicine of Shahrekord University, west central Iran. Six dilutions (5, 10, 20, 40, 60 and 80 µL/cm(3)) of both esse...

ticks are an important problem among zoonotic diseases. main veterinary species of hard ticks are: hyalomma sp. boophilus sp and rhipicephalus sp. among them hyalomma sp. have widespread distribution in iran and middle east. the best method to control hyalomma sp. is immunological one, by using antigens, which causes immunologic and physiologic reactions in host.bm86 is one of the best antigens...

The control of the southern cattle tick, Boophilus microplus (Canestrini), in Mexico and many other countries relies on chemical acaricides. Boophilus microplus has developed resistance to all major classes of acaricides in recent years. To gain a better understanding of the resistance and to develop resistance management strategies that benefit both Mexican ranchers and USDA's cattle fever tic...
