The sterile insect technique is now in use to eliminate the fly in other areas of Central America.

After the great success of a pilot project on Curaçao, NWS was completely eradicated from the United States and Mexico.

SIT has played a vital role in the eradication of the tsetse fly population in Zanzibar and in the control of screwworms in several countries.

This proven nuclear-derived technique has been used for over 50 years to control major agricultural insect pests, such as fruit flies, tsetse flies, screwworm flies and moths.

Eradication of NWS is important for increasing livestock production for a growing population without encroaching on the forests, jungles and environment of Central and South America.

The success of this international cooperation, which culminated in Mexico being declared NWS-free in 1991, is one of the greatest achievements in animal health in this century.

The American department of agriculture has eliminated the screwworm in the United States and South America, a fly which feds itself on blood and attacked livestock and humans by infecting wounds.

By the end of June 1991 more than 600 million NWS sterile flies, produced by the Mexico-United States Commission for the Eradication of the Screwworms, had been dispersed over 40000 km² of northern Libya.
