POPS Scientists Research Disappearance Of Bumblebees Thorp, an emeritus professor of entomology from the University of California at Davis, found one solitary worker last year along a remote mountain trail in the Siskiyou Mountains, but hasn't been able to locate any this year He fears that the species — Franklin's bumblebee — has gone extinct before anyone could even propose it for the endangered species list. To make matters worse, two other bumblebee species — one on the East coast, one on the West — have gone from common to rare.

POPSThreats to Bumblebees Fly Under Radar But if bumblebees were to disappear, farmers and entomologists warn, the consequences would be huge, especially coming on top of the problems with honeybees, which are active at different times and on different crop species. Bumblebees are responsible for pollinating an estimated 15 percent of all the crops grown in the U.S., worth $3 billion, particularly those raised in greenhouses. Those include tomatoes, peppers and strawberries. Demand is growing as honeybees decline. In the wild, birds and bears depend on bumblebees for berries and fruits. There is no smoking gun yet, but a recent National Academy of Sciences report on the status of pollinators around the world blames a combination of habitat lost to housing developments and intensive agriculture, pesticides, pollution and diseases spilling out of greenhouses using commercial bumblebee hives.
