Insects have a shorter life span, so it would be much easier to do survival trials. Long-term toxicity would also be less of a problem.
Please see my reply to mouton.
There would be a lot of good models because there are so many different types of insects…
Models are nice, but the limiting factor on the number of approved drugs is the more regulatory than scientific.
The FDA approval standards for animal drugs is different (and lower) than it is for humans.
However, if humans (including the FDA reviewers) were insects, the FDA would presumably use the existing standards for human drugs, not the existing standards for animal drugs.
