A decline in the number of honeybees |
[00:08.23] |
is a growing problem worldwide. |
[00:11.26] |
The decreasing bee population could contribute |
[00:14.91] |
to an increase in prices for crops |
[00:17.74] |
that depend on pollination by honeybees. |
[00:21.29] |
Researchers continue to study the decline |
[00:24.22] |
while beekeepers like Terrence Ingram |
[00:27.62] |
struggle to keep their bee colonies alive. |
[00:31.05] |
He says he loves being at the center of a swarm of bees. |
[00:38.97] |
"I love beekeeping. It's one of God's greatest miracles." |
[00:44.01] |
He has raised honeybees since 1954 in managed colonies |
[00:49.59] |
behind his house in rural Apple River, Illinois. |
[00:54.27] |
"We had 250 hives at one time. |
[00:56.41] |
We sold five, six tons of honey a year." |
[00:59.97] |
But that number is declining. |
[01:02.31] |
"Now we’re down to about probably four tons." |
[01:05.25] |
Not because the 73 year-old beekeeper is slowing down, |
[01:09.59] |
but because there are fewer bees producing honey. |
[01:13.83] |
He says the decline in his bee population began in 1996. |
[01:20.05] |
he blames that decline on the use of insecticides |
[01:24.38] |
and herbicides on the farmland surrounding his property. |
[01:29.17] |
"Every three weeks that summer, |
[01:30.82] |
they were spraying with the airplane, |
[01:32.81] |
and by the end of the year, |
[01:34.35] |
I didn't have any of my 250 hives left." |
[01:36.49] |
This caught the attention of researchers like Christian Krupke, |
[01:41.54] |
a professor at Purdue University who studies bees and other insects. |
[01:47.52] |
"There have been similar reports from Europe in the past, |
[01:50.85] |
and so we looked into it a little bit further |
[01:52.80] |
from the point of view of wondering |
[01:54.29] |
first of all what is killing these bees, |
[01:56.39] |
and second of all how are these bees acquiring |
[01:58.93] |
whatever this toxic chemical is." |
[02:01.51] |
Experts say there are many reasons for the worldwide bee decline, |
[02:06.35] |
not just insecticides. |
[02:08.89] |
But in this case, Proffessor Krupke and his colleagues |
[02:13.32] |
thought insecticides might be the cause. |
[02:16.91] |
So they studied the insecticides |
[02:20.61] |
- known as neonicotinoids - that are applied to seeds |
[02:24.49] |
as they are planted in the ground, rather than sprayed from above. |
[02:29.12] |
"The two compounds that kept coming up when we tested these dead bees |
[02:33.24] |
were the pesticides clothianidin and thiamethoxam. |
[02:37.32] |
Those are insecticides that are applied to corn seeds." |
[02:39.60] |
About 30 years ago, |
[02:41.45] |
there were 4 million managed bee colonies throughout the United States. |
[02:47.07] |
Today, there are fewer than 2 million. |
[02:51.36] |
Researchers like Professor Krupke blame that in part on the use of insecticides. |
[02:57.14] |
"Can we get by without neonicotinoids insecticides in these field crops? |
[03:01.67] |
I believe we can. I believe we have data that show that we can." |
[03:04.52] |
This December, the European Union plans |
[03:08.20] |
to ban the use of some insecticides |
[03:10.69] |
that researchers have linked to bee deaths. |
[03:14.33] |
No such restrictions are planned in the United States. |
[03:18.62] |
Illinois beekeeper Terrence Ingram says |
[03:22.31] |
some of the damage already done is permanent. |
[03:26.34] |
"We've got many bee keepers around here that have quit, |
[03:29.19] |
just gone out of business because they can't succeed." |
[03:32.03] |
But not Terrence Ingram, he says his passion for bees |
[03:36.32] |
is just as strong as it was when he tended his first colony, |
[03:41.34] |
more than 60 years ago. |
[03:44.03] |
"See one bee coming out right here, she is attend coming up." |
[03:49.86] |
