Examples

  • Because they are well protected, larvae that create shelters from the leaves they feed on may be attractive hosts for parasitoids.

    Academic text (2001)
  • A pathogen and several species of parasitoid flies are the most effective biological control agents currently known.

    Academic text (2004)
  • Everyone, scientists and nonscientists alike, should open up an insect and see a parasitoid at least once in their lives.

    Academic text (2002)
  • Parasitoid young hatch inside the sharpshooter eggs, then proceed to feast on them.

    Academic text (2001)

    Academic text (2001)
  • Among the sharpshooter's most formidable foes, for example, are egg parasitoids—insects that unabashedly lay their eggs inside sharpshooter eggs.

    Academic text (2001)

parasitoid singular

Morphology

parasitoid = parasite (semi-transparent) = parasite + oid

Formally 'parasite' + '-oid' suggests 'parasite-like', but the specific entomological meaning (an organism whose larvae kill the host) is specialized and not fully derivable by average learners.

Etymology

Parasitoid is built from parasite ('one who eats at another's table') plus -oid meaning 'like', as in humanoid. So a parasitoid is an organism that is 'parasite-like' but that eventually kills its host, a meaning often used for certain wasps and their larvae.
