He had to climb into the hog pens to smear medicine on the wounds of uncooperative sows. вЂњEvery plant that we grew,вЂќ he later said, вЂњthere was some type of insect that was causing damage.вЂќ Screwworms infected the farmвЂ™s cows and pigs, and Knipling remembered them as one of the worst pests. As a boy, he had waged constant war against insect pests on his familyвЂ™s Texas farm. Knipling, a USDA entomologist who, in the 1930s, spent long hours watching screwworms mate. The man who came up with the scheme, and believed in it most passionately, was Edward F.

They had to bootleg money from other programs because they didnвЂ™t have enough funding. In the early days of the eradication effort, USDA scientists were not so certain of success-or longevity. вЂњWe should be here for the next 100 years.вЂќ

вЂњWe will be here for a long time,вЂќ a COPEG staff member in Panama told me with evident pride. More screwworm flights were scheduled for the next day, a Wednesday, and Thursday and Saturday and Monday and so on and on.

The day before I landed at Tocumen International Airport, two small COPEG planes had taken off and released their precious loads of screwworms over the Panama-Colombia border. They work for a joint commission of PanamaвЂ™s agricultural department and the USDA known as COPEG, or the ComisiГіn PanamГЎвЂ“Estados Unidos para la ErradicaciГіn y PrevenciГіn del Gusano Barrenador del Ganado. As startling as it was to Floridians, it had been just a small, gruesome blip in the history of the screwworm.ДЄ transcontinental screwworm barrier has been in place for 50 years-longer than many of the people who now maintain it have been alive. The Keys outbreak was long over by then, quelled within months by the release of sterile screwworms from Panama. This past August, I went to Panama to meet the people who maintain the screwworm barrier. Those who fight it must be relentless too. The insect is relentless in its search for hosts. The slightest oversight could undo all the work that came before. Inspectors cover thousands of square miles by motorcycle, boat, and horseback, searching for stray screwworm infections north of the border. A screwworm-rearing plant operates 24/7 in Panama. Every week, planes drop 14.7 million sterilized screwworms over the rainforest that divides the two countries. The barrier is an invisible one, and it is kept in place by constant human effort. To get the screwworms out, the USDA to this day maintains an international screwworm barrier along the Panama-Colombia border.

The eradication was a resounding success.

and then in Mexico and Central America-all the way down to the narrow strip of land that is the Isthmus of Panama. At their urging, the United States Department of Agriculture undertook what would ultimately become an immense, multidecade effort to wipe out the screwworms, first in the U.S.

They dared to dream of an entire country free of screwworms. ranchers began to envision a new status quo. hominivorax or вЂњman eaterвЂќ-so named after a horrific outbreak among prisoners on DevilвЂ™s Island, an infamous 19th-century French penal colony in South America.ДЇor untold millennia, screwworms were a grisly fact of life in the Americas. In fact, the screwwormвЂ™s scientific name is C. Their range extended from Florida to California, and they infected any living, warm-blooded animal: not only cattle but deer, squirrels, pets, and even the occasional human. Screwworms once killed millions of dollarsвЂ™ worth of cattle a year in the southern U.S. In those days, screwworms found their way into cattle through any opening in the skin: the belly buttons of newborn calves, scratches from barbed wire, even a tick bite. If you had asked an old-time Florida rancher though, he might have told you boyhood stories of similarly disfigured and dying cattle. That something, lab tests would later confirm, was the New World screwworm, a parasite supposed to have been eradicated from the United States half a century ago.
