Researchers and conservationists expressing their concern regarding disappearing of honey bees stated that honey bees are a crucial part of the ecosystem.

Experts said that over the last decade honey bees have been disappearing in record numbers but scientists are not exactly sure about the reason behind the decline.

Honey Bees populations rose by backyard gardeners and professionals are declining across the United States. In Michigan itself the honey bee population has dropped 30% to 50% each year.

Makayla Putnum, president of the Keeping Bees Club at Aquinas College said, "Honey bees are very different than wasps or any other kind of bees, they're actually very docile and they don't want to sting you because they die when that happens".

The club raises bees in Grand Rapids to study them and to raise awareness of their importance. Sophomore Aaron Skorka is also a member of the club.

The club members as part of their duties keep an eye on the health of the hives, and also make sure that there are not any signs of death or abnormal activity.

The club lost a hive in this spring to excess moisture in the hive. But across the world, the bee keepers are losing bees by the millions.

Dr. Clark Danderson, an associate biology professor at Aquinas sated that what they are presently seeing in these colonies is that the bees are disappearing very fast. One expects to lose a portion of hive every year.

The disappearance of bees is known as colony collapse disorder, a phenomenon not truly understood by scientists, said experts.

Danderson in explanation said that normally if they have say too much moisture in their hives or get sick, the dead bees will be there in the hive. But in the case of colony collapse disorder, they are not there.

Danderson said there are many theories behind disappearing of bees like pesticides, mites and limiting food sources, but he believes that all three are jointly are responsible for the loss.
