What is the most common predator of the animal that is susceptible to the parasite Parelaphostrongylus tenuis and typically inhabit boreal forests and temperate broadleaf and mixed forests of the Northern Hemisphere in temperate to subarctic climates?
Parelaphostrongylus tenuis Parelaphostrongylus tenuis (also known as meningeal worm, brainworm, or moose illness) is a neurotropic nematode parasite common to white-tailed deer, "Odocoileus virginianus", which causes damage to the central nervous system. Moose ("Alces alces"), elk ("Cervus canadensis"), caribou ("Rangifer tarandus"), and mule deer ("Odocoileus hemionus") are also susceptible to the parasite but are aberrant hosts and are infected in neurological instead of meningeal tissue. The frequency of infection in these species increases dramatically when their ranges overlap high densities of white-tailed deer.
Exhyalanthrax Exhyalanthrax is a small genus of bombyliid flies. Bombyliids are commonly known as "bee flies" due to their resemblance to bees. "Exhyalanthrax" are found in the Afrotropical ecozone and the Palearctic ecozone. Exhyalanthrax spp. are pupal parasitoids."Exhyalanthrax afer" has been reared from pupae of tachinid and ichneumonid parasitoids of "Thaumetopoea pityocampa" and from the pupae of this species and other Lepidoptera. It has also been bred from cocoons of "Neodiprion sertifer". Several African species have been reared from the puparia of tsetse flies and from puparia of other Diptera. An "Exhyalanthrax" sp. has also been found preying on cockroach, ("Heterogamisca chopardi" Uvarov) oothecae in Saudi Arabia. It has been suggested that "Exhyalanthrax" might be utilised as
