Perspectives on the bacterial control of vectors in the tropics.
Biological agents have not found wide application in the control of insects that transmit agents of human disease. Fungal pathogens may have a potential for field use, but environmental constraints, lack of knowledge of their life cycle, or dependence on production in vivo, have prevented their widespread use. In fact, sporogenous bacteria are the only biological agents used on a large scale for the control of mosquitoes and blackflies that transmit diseases in the tropics. Two bacteria, Bacillus thuringiensis sp. israelensis and B. sphaericus are very effective for the control of these vectors. In this article, Jean Marc Hougard and Christian Back discuss various factors associated with the use of bacteria for vector control, and the prospects for further developments.
