Can molecular biology contribute usefully to vector control?

It is argued that further work in molecular entomology should be driven by the practical problems that vector controllers have, not by what molecular biologists can and would like to do. The usefulness is discussed of molecul ar approaches to (1) insecticide resistance, (2) identification of sibling species, sporozoites and the origin of infections, vector populations and b lood meals, (3) genetic control by sterile males or population replacement.
