Collection of free-living nymphs and adults of Amblyomma hebraeum
(Acari: Ixodidae) with pheromone/carbon dioxide traps at 5 different ecological sites in heartwater endemic regions of South Africa.--Exp.
For example, survival of Amblyomma hebraeum
larvae dropped precipitously at 70% RH compared to higher RHs (Londt and Whitehead 1972), Ixodes ricinus larvae died sooner in open, grassy than in forest habitats (Daniel et al.
The role of tick moulting hormone, ecdysteroids on salivary gland function, oogenesis, and oviposition, and its regulation by neurotransmitter dopamine has been investigated in Amblyomma hebraeum and R.

These tick-borne diseases include, but are not limited to, heartwater disease (Ehrlichia ruminantium) transmitted by Amblyomma hebraeum (bont tick); red water disease (Babesia bigemina) transmitted by Rhipicephalus (Boophilus) decoloratus (blue tick); and East coast fever (Theileria parva parva) and corridor disease (Theileria parva lawrencei) transmitted by Rhipicephalus appendiculatus (brown ear tick).
Eight tick species were found: Amblyomma hebraeum Koch, 1844; Haemaphysalis elliptica (Koch, 1844); Hyalomma rufipes Koch, 1844; Rhipicephalus appendiculatus Neumann, 1901; Rh.
Efficacy of four commercial DEET repellents against Amblyomma hebraeum
(Acari: Ixodidae), the principal vector of Rickettsia africae in southern Africa.
To the Editor: Rickettsia africae, the causative agent of African tickbite fever, is transmitted by Amblyomma hebraeum
In contrast, African TBF is typically transmitted by particular cattle and game ticks (Amblyomma hebraeum
in southern Africa) in a rural setting.
Transmission of a spotted fever group rickettsia by Amblyomma hebraeum
Subsequently, numerous cases have been reported in tourists returning from southern Africa, where the cattle tick Amblyomma hebraeum
is the vector (2,3).
