Ixodiphagus is a genus of encyrtid wasps (order Hymenoptera, superfamily Chalcidoidea) that are obligate parasitoids of ticks (order Ixodida). Females oviposit into larval or nymphal ticks; development resumes inside the nymph and the emerging adult wasps kill the host. Because of this unique biology, Ixodiphagus has been repeatedly investigated as a biological control agent for medically and veterinary important ticks.
