Most biologists use the term parasitoid to refer only to insects with this type of life history, but some argue the term should be used more embrasively to include parasitic nematodes, seed weevils, and certain bacteria and viruses (e.g., bacteriophages), all of which obligately destroy their host.

Moreover, natural enemies such as parasitoid wasps and ants are likely to increase their abundances and activity rates if summer temperature rises.

As this virus and the parasitoid wasp '' Cotesia jucunda '' are both important controllers of the survival of moth caterpillars, increased UV-B radiation levels could possibly lead to increased moth populations and birch forest defoliation.
