Just a quick addendum on the potential use of engineered parasites
within an environment to manipulate a target host. It's already known
that certain parasites can cause behavioral changes in an infected
host. For example, Toxoplasmosis Gondi, a parasite that infects mice,
cats, and even humans, will cause a behavioral shift in mice that
reduces inhibition and fear, leading the infected mouse to a cat as
part of its life cycle. It may well affect the behavior of infected
humans as well:

Viral parasites, such as a retrovirus, can impart nongerm-line genes
into a host. HIV is the most commonly known of these.

Also, outside of parasites, note that shifting population sizes of a
secondary interactors to a primary target host may be an easier
approach than directly modifying the genomes of organisms nearby on
the target's ecological web.
