Conservation-induced extinction is where efforts to save

lice.[1]

Examples

  • Parasite: Colpocephalum californici – host: California condor[2]
    The parasite most probably became extinct when the last individuals of its only host species were captured for a captive-breeding program; all parasites found were deliberately killed in an attempt to assist the host's survival.[3]
  • Parasite: Felicola isidoroi – host: Iberian lynx.[4]
    As with Colpocephalum californici, likely became extinct when the last individuals of its host species were taken into captivity and deloused to assist survival.
  • Parasite:
    scimitar-horned oryx
    The host specificity of this parasite is uncertain. Either it was specific to the scimitar-horned oryx and became extinct during captive breeding of the host, or – alternatively – it may be specific to the addax
    and possibly still surviving in the wild.
  • Parasite: Rallicola guami – host: Guam rail
    The only known host species of this parasite exists exclusively in captivity and kept under veterinary control. Little information about the fate of the parasite, likely extinct.[5]
  • Parasite: Rallicola pilgrimi – host: little spotted kiwi[6]
    The parasite most probably became extinct when the last individuals of its only host species were captured and, after routine veterinary antiparasitic treatments, re-introduced into predator-free islands.

Erroneous example

The

trichodectid louse of the black-footed ferret has been mentioned in the literature several times[7] as a parasite that became extinct during the captive breeding program of the host. However, this parasite most probably never existed as a separate species from Neotrichodectes minutus.[1]
