Onychomys torridus), el raton silvestre (Microtus spp.), un insectivoro como la musarana de Vagrant (Sorex vagrans) y el murcielago marron (Eptesicus fuscus) (Beck et al).

She decided to take a look at southern grasshopper mice,
Onychomys torridus, carnivorous rodents known to chow down on scorpion species less toxic than bark scorpions.

In addition to the recognized arenavirus hosts, other Texas rodent genera (
Onychomys, Baiomys, Peromyscus, Dipodomys, and Chaetodipus) have tested positive for arenavirus antibodies (Milazzo et al.
We captured three other cricetids (

Although bark scorpions (Centruroides spp.) are well known for possessing potent neurotoxins that might deter a vertebrate enemy, grasshopper mice (
Onychomys spp.) are resistant to the lethal effects of the venom and feed voraciously on Centruroides (Rowe & Rowe 2006, 2008); an effectively delivered sting, however, often causes sufficient pain for the mouse to drop the scorpion, providing an opportunity for its escape (Rowe & Rowe 2006).

Similar variation in some North American rodents (e.g.,
Onychomys, Spermophilus, and Peromyscus) and the high resistance of a few (e.g., Dipodomys) provide reasons for optimism.
