Billionth sterile fly released in Texas to curb screwworm resurgence
The U.S. Department of Agriculture released its billionth sterile fly in Texas as part of the sterile insect technique to interrupt the New World screwworm’s breeding cycle; the pest was eradicated decades ago and the program is being boosted after new U.S. cases emerged in June, with fewer than 50 cases reported so far this year.
