Scientists begin work to eliminate screwworms by releasing sterilized male flies to mate with native flies, thereby interrupting the population cycle. Edward F. Knipling, an entomologist at BARC and other ARS laboratories, and fellow entomologist Raymond C. Bushland developed the framework of the sterile insect technique (SIT). By the 1980s, screwworms are eliminated from the United States. Research using SIT continues at ARS laboratories all around the country.
