The Honeybee Act of 1922: How the U.S. Banned Bee Imports

Why Congress banned live honey bee imports in 1922, how the law changed over four later amendments, and why it still shapes American bee genetics today.

On August 31, 1922, Congress passed the Honeybee Act, a short federal law that banned importing live adult honey bees into the United States — not to protect American bees from competition, but specifically to keep out the acarine tracheal mite that had just devastated British beekeeping under the name “Isle of Wight disease.” It’s one of the few pieces of federal legislation named directly for a single insect, and it quietly shaped the genetics of the American honey bee population for the rest of the 20th century.

Key Takeaways

  • The Honeybee Act of 1922 restricted the importation of live adult honey bees into the United States, motivated primarily by the acarine (tracheal) mite epidemic then devastating British and Irish colonies.
  • USDA researchers and specifically authorized cooperators were effectively the only parties allowed to import bees under the law, cutting off the routine commercial queen and package imports that had been common before 1922.
  • The Act has been amended four times since 1922 — in 1947, 1962, 1976, and 1994 — each time adjusting scope and authority rather than replacing the original framework.
  • The 1962 amendment expanded the restriction from just Apis mellifera to the entire genus Apis and tied import eligibility to a country’s disease-control standards.
  • The law is still on the books today (codified at 7 U.S.C. § 281), now administered by the Secretary of Agriculture with authority to prohibit or restrict bee imports to guard against disease, parasites, or genetically undesirable stock.

Why Congress Banned Bee Imports in 1922

The immediate trigger for the Honeybee Act was a crisis nobody in the United States had actually experienced yet. Starting in 1904–1906, British beekeepers began reporting a mysterious, catastrophic die-off that came to be known as “Isle of Wight disease” — later attributed largely to the newly described acarine mite, Acarapis woodi, though the exact cause was debated for decades (a story this site covers in full in its history of Isle of Wight disease). By the early 1920s, the epidemic had wiped out an estimated 90 percent of honey bee colonies across Britain and Ireland. American entomologists and the beekeeping industry, watching a disease with no known cure erase most of a country’s bee population within roughly fifteen years, pushed for a preventive import ban rather than wait to find out whether the same mite would cross the Atlantic in a shipment of queens.

What the Original Act Actually Did

The 1922 law restricted the importation of living adult honey bees into the United States, with USDA researchers and their specifically authorized cooperators effectively the only parties permitted exceptions. Before 1922, importing live queens and package bees from Europe had been a routine part of the American beekeeping trade — it’s exactly the kind of shipment Frank Benton, the USDA’s own bee explorer, had built a career managing (a story covered separately in this site’s profile of Frank Benton and his Cyprian and Caucasian bee imports). The Act didn’t touch domestic movement of bees between states, and it didn’t ban imports of bee products like honey or wax — only live adult bees, which is specifically where a hitchhiking mite would travel.

Four Amendments in Seventy-Two Years

The Honeybee Act didn’t stay frozen in its 1922 form. It was amended in 1947, 1962, 1976, and 1994, each revision adjusting the law’s scope rather than replacing its basic premise of USDA-controlled entry. The 1962 amendment is the most significant of the four: it broadened the restriction from just the Western honey bee, Apis mellifera, to the entire genus Apis — closing a gap that would otherwise have left other honey bee species technically importable — and it shifted the standard for approval toward whether the exporting country had adequate disease-control precautions of its own, rather than a flat prohibition. Later amendments refined the Secretary of Agriculture’s authority to prohibit or restrict imports specifically to prevent disease, parasites, “genetically undesirable germ plasm,” or undesirable species and subspecies from entering the country — language that still governs bee import policy today.

A Law That Shaped American Bee Genetics by Accident

A side effect of seventy-plus years of restricted imports is that American commercial bee genetics developed with far less routine infusion of new European stock than they otherwise would have. Where Frank Benton and other USDA-era importers had been actively bringing in Cyprian, Carniolan, and Caucasian bees around the turn of the century to diversify and improve American stock, the 1922 Act effectively froze that pipeline. Later, more targeted exceptions — such as the U.S. government’s own controlled importation of Russian honey bee stock in the late 1990s specifically for Varroa resistance research — had to work through the same USDA-controlled exception process the 1922 law established, rather than through the kind of open commercial import trade that existed before it.

The Honeybee Act Today

The Honeybee Act, as amended, is codified at 7 U.S.C. § 281 and remains active federal law. In practice, it means anyone seeking to bring live bees into the United States today — whether a research institution or a commercial operation — has to go through USDA’s Animal and Plant Health Inspection Service (APHIS), which evaluates the request against the same disease-and-genetics framework the law has carried since 1962. It’s a rare case of a single-purpose, insect-specific law from the early 1920s still functioning largely as designed a century later, and it’s worth knowing about for anyone trying to understand why the American honey bee population looks genetically the way it does.

Frequently Asked Questions

What exactly did the Honeybee Act of 1922 ban?

It restricted the importation of living adult honey bees into the United States, with exceptions effectively limited to USDA researchers and their authorized cooperators. It did not restrict domestic interstate movement of bees or imports of honey and other bee products.

Why was the law passed specifically in 1922?

Congress acted in response to “Isle of Wight disease,” an acarine mite epidemic that had devastated British and Irish honey bee populations since the mid-1900s, wiping out an estimated 90 percent of colonies in Britain and Ireland by the early 1920s. The goal was to keep the same mite out of the United States.

Is the Honeybee Act still in effect?

Yes. As amended in 1947, 1962, 1976, and 1994, it remains active federal law, codified at 7 U.S.C. § 281, and it still governs how live bee imports into the United States are evaluated by USDA APHIS today.

Did the 1922 Act stop all bee-related trade with other countries?

No. It specifically targeted live adult bees. Imports of honey, beeswax, and other bee products were not restricted by this law.

How did the 1962 amendment change the law?

It expanded the restriction from covering just Apis mellifera to the entire genus Apis, and it tied import approval to whether the exporting country had adequate disease-control precautions, rather than a blanket ban.
