... A fundamental problem with weed biocontrol agents is their lack of sufficient virulence. Biocontrol agents must be able to kill a weed in its seedling stage, they must be host specific, and cost efficient, preferably at a cost that is less than that of herbicides.

Parasitoid
A parasitoid is an organism that spends a significant portion of its life history attached to or within a single host organism in a relationship that is in essence parasitic; unlike a true parasite, however, it ultimately sterilises or kills, and sometimes consumes, the host. Thus parasitoids are similar to typical parasites except in the more dire prognosis for the host.
