Interesting, I once read that there were no cattle or horses South of the
Sahara Desert, because they were killed off by trypanosomiasis (sleeping
sickness) from the tsetse fly. Enormous implications for neotony and the
structure and progress of transport and civilisation. (until Europeans
imported them).
Insect-borne disease has had a major role in history. Caesar drained the
swamps around Rome to prevent malaria- this must have been a big help.
As an aside. Now, we get toothbrush-borne disease. If you've ever had a bug
you can't shake for weeks, take a look at
