Optimization of artificial membrane feeding system for lone star ticks, Amblyomma americanum (Acari: Ixodidae), and experimental infection with Rickettsia amblyommatis (Rickettsiales: Rickettsiaceae)

Journal of Medical Entomology, 2023
Abstract With the introduction of siliconized artificial membranes, various artificial feeding systems (AFS) for hard ticks (Ixodidae) have been developed over the last decades. Most AFS utilize similar core components but employ diverse approaches, materials, and experimental conditions.

Effect ofRickettsia rickettsii(Rickettsiales: Rickettsiaceae) Infection on the Biological Parameters and Survival of Its Tick Vector—Dermacentor variabilis(Acari: Ixodidae) [PDF]

Journal of Medical Entomology, 2015
Rocky Mountain spotted fever, caused by Rickettsia rickettsii, is a potentially fatal tick-borne disease spread from North America to Argentina. The major vectors of R. rickettsii in the United States are Dermacentor andersoni Stiles and Dermacentor variabilis (Say). It is generally believed that vector ticks serve as major reservoirs of R.
