Higher-than-normal losses of bees over
the winter in some years have resulted in economic setbacks for some
beekeepers, though the USDA found last year’s loss rate much lower. In
reporting on these numbers, many journalists fail to recognize that worker bees
only live for six weeks in the summer and hive strength can quickly regenerate
to compensate for losses.
The USDA cites many factors afflicting
bees, but the primary one is the epidemic spread of the varroa mite and the
crippling diseases it vectors into the bee. Additional problems include lack of
forage and the stresses of the transcontinental pollination business. As for
pesticides, the USDA places them near the bottom of the list. In fact, the USDA
is concerned about the miticides beekeepers themselves use to control varroa.
It’s clear from real world experience
and extensive field studies that neonics are not a significant factor. Bees
thrive in the millions of acres of neonic-treated canola grown in Western
Canada and the pesticides are used extensively in Australia, a continent that
has some of the healthiest bees in the world.
But while bees aren’t harmed by these
popular pesticides, farmers — and consumers — would be if they were banned. Neonics
are all that is saving the U.S. citrus industry from destruction by "citrus
greening" disease. Without them, rice and cotton farming would become
economically unviable throughout much of the U.S. Leafhoppers would devastate
vineyards in California and the Pacific Northwest. Neonics are one of the most
critical pesticides used in modern agriculture and safely utilized in the
production of numerous crops, from corn and soy to vegetables of all kinds.
We must understand why activist
organizations have decided to target neonics for elimination. They won the day
in Europe, where the EU overrode the doubts of its own scientists and pushed
through a political ban. As a matter of fact, the EU just conducted a survey to
find out how bad the losses really are and were clearly taken aback by the
findings. Seventy-five percent of the bee population experienced overwinter
losses of 15 percent or less — a rate considered completely normal in the
United States. High overwinter losses occurred among 5 percent of the bee
population in the very cold north.
Summertime losses were insignificant.
The biggest danger to bees in the EU are the older classes of pesticides,
especially the pyrethroids now used as a result of the neonic ban.
The activists want us to ban first and
ask questions later. We should not legislate based on sensationalist and
fallacious press accounts. The facts clearly don’t support the calls for a ban.
