You might recollect the buzz of recent years
regarding the precipitous decline in honey bee populations. Since 2006, most
apiaries have seen their bee colonies decrease by 30 to 90 percent per year. Some
hives have been totally wiped out.
25 percent had once been the maximum rate of
mortality in northern states that had significant cold-weather die-offs. But,
the recent deaths have been occurring everywhere and during the spring and
summer when temperatures are perfect and food is plentiful.
For some time, the reasons for this frightening extirpation
remained unknown, and the moniker of “colony collapse disorder” was placed upon
it as a catch-all for what could be either natural or man-made causes. Those
days of uncertainty are gone: It was
determined over the past couple of years, by independent studies released in prominent
journals like Science and Nature, that the root cause of honey bee
deaths was the family of pesticides known as neonicotinoids. Last year, those
findings were affirmed just across the border by Ontario’s Ministry of Agriculture, Food and Rural Affairs which
discovered that 70 percent of the dead bees across the province showed exposure
to neonicotinoids.
These insect nerve agents have been used in
increasing abundance on corn since 2005, after entering the market in the 1990s
(it is now used on most all commercial corn in the United States). That
timeline of pervasiveness aligns perfectly with the sudden decline in bee
populations. Produced by Bayer, neonicotinoids are applied directly to the seed
and thus become a part of the adult plant, including the nectar and pollen upon
which the bees feed. The chemical doesn’t kill bees outright, but it seriously
impairs their development and behavior, which accounts for the inability of the
bees to feed properly (they waste away), maintain their colonies and replenish
them through adequate reproduction.
Other countries are taking steps to combat this scourge.
In Canada, Ontario officials have encouraged farmers to inform beekeepers when
they are planting, because the dust associated with planting can carry
neonicotinoids to wildflowers in adjoining hedgerows as well as lawns and
pastures even a few miles away. This would allow the beekeepers to move their
stock to another area when planting is underway. But, it does nothing to
address the longer-termed problems associated with pollination once the plants
grow.
A more powerful means of suppression is taking
place in the European Union. Starting December 1st of this year and
lasting through 2014 and 2015, the use of three specific types of neonicotinoids
will be totally banned in the EU. This 2-year moratorium will see a return to
20th century insecticides and a likely resurgence in honey bee
populations.
Germany and the United Kingdom passed on the ban
and will allow for the continued use of the offending compounds. That’s not any
different than what is happing here in the US. Even though federal studies link
neonicotinoids to colony collapse, including a report released by the USDA and
EPA earlier this month, the government has no immediate plans to limit or ban
the use of neonicotinoids -- a major study on the impact of neonicotinoids
won’t be made available from the EPA until 2018.
2018 could likely be too late, especially if a ban
is determined to be necessary; that in itself could take a few more years.
American farmers (especially fruit growers whose trees need more help from bees
than field crops do) – and those who consume their produce -- need answers and
actions now. If bees were wiped out, or something close to it, fruits and
vegetables wouldn’t get the pollination they need. Estimates show that the
total loss of crops would approach $15 billion per year.
Neonicotinoids are certainly proving to be a bane
to the health of the environment, the economy, and the people.
