I think one of the insect hosts is the blod-sucking conenose bug (true bug).
This insect is also found in the southwest USA (I have caught more than
one). I have often wondered why chaga's is not found in the southwest USA.
I have heard rumors that there is another trypanosome that infects the bugs
in the southwest USA and competition prevents the spread of chaga's. This
is speculation and rumor. I would appretiate any information anyone might
have on this.
