Bacteria living in insect guts have also been recruited, reports Leslie Harris O'Hanlon. Engineering these bacteria to produce a protein lethal to the parasite that causes Chagas' disease can clear insects of parasites.

There is a widespread lack of regulations concerning release of engineered insects and impacts of such releases on other insects and the wider environment have yet to be studied in detail.
