The Dermacentor (Acari, Ixodida, Ixodidae) of Mexico: hosts, geographical distribution and new records.

Pictorial key to the adults of hard ticks, family Ixodidae (Ixodida: Ixodoidea), east of the Mississippi River.

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.

Tick Immunity to Microbial Infections: Control of Representative Bacteria in the Hard Tick Dermacentor variabilis (Acari: Ixodidae)

Hosts of the immature stages of the rhinoceros tick, Dermacentor rhinocerinus (Acari, Ixodidae).

The collection of the immature stages of Dermacentor rhinocerinus from host animals is described for the first time. These are the bushveld gerbil (Tatera leucogaster, from which larvae and nymphs were collected, the red veld rat (Aethomys crysophilus), from which a larva was collected, and the Natal multimammate rat (Mastomys natalensis), from which a nymph was collected. The rodents were exam...

Factors affecting the geographical distribution of Ixodes ricinus (Acari: Ixodidae) and its transmitted pathogens in Europe

Many biotic and abiotic factors are involved in determining the distribution of the important tick vector Ixodes ricinus (Acari: Ixodidae) in Europe, as well as in driving changes in its occurrence within its prior endemic zones. This paper aims to review some of the main factors that could have affected the geographical distribution of this tick species and its transmitted pathogens in Europe ...
