Although miticides have been developed that are effective … The researchers found rapid and widespread declines in bumblebee populations across both continents. Amid the worry over the loss of honey bees, a far quieter but just as devastating loss is occurring among lesser known native bee populations. The main cause of honey bees being endangered are parasites, including tracheal and varroa mites that were introduced into North America in the 1980s. In the study, the effects of climate change on bumblebees were observed independent of these human practices, meaning if those are accounted for, too, the risk of extinction would be even greater. Today, half of all bumble bee species once found in Illinois have disappeared or declined. Genetically-modified crops have mixed effects on bumble bees. Four have already decreased nearly to extinction while suffering range contractions of up to 87%. Bumble bees face many threats, including habitat loss, pesticides, introduced diseases, climate change and competition from honey bees, says Sarina Jepsen, endangered species program director for the Xer… There is no sign, however, of the rusty-patched bumble bee that Colla has been searching for all summer. To collect this pollen, a bumble bee grabs onto the flower with her mouth and vibrates her wings rapidly (over 130 beats per second), shaking the pollen out, in a process called buzz pollination. Most species of bumblebee live in colonies, but their colonies are much smaller than the honey bees or wasps who can have up to several thousand individuals, the bumblebee colony will only consist of around 50 – 150 individuals. Insect-resistant crops lead to decreased pesticide use but have some negative effects on bees. The … Sheila R. Colla and Laurence Packer, the lead researchers in the study found pesticides, loss of habitat and commercially-produced bumblebees spread pathogens to bumble bees, which in turn affected bumble bee … In response to climate changes, bumble bee ranges, abundance, and activity have changed.

What our study says is that that answer is no across entire continents.". These parasites cause diseases that can be harmful to the bees' colonies, such as a disease that causes newly raised bees to emerge with malformed wings and the inability to fly. This external parasite is a huge cause … "We're not saying that what we all need to do is immediately start living in a hut in the woods to recover the situation. While commercial bumble bee operations can do a few things to reduce the spread of disease (e.g., not importing bees from other countries, disease screening, preventing cultivated bee escape), individual citizens have a role to play as well. Contrast that with the fewer than 10 known species of honey bees. They can fly in weather conditions (cold, cloudy) that other bee species can’t.

"Predicting why bumble bees and other species are going extinct in a time of rapid, human-caused climate change could help us prevent extinction in the 21st century."—Dr. Rather, many interacting threats have converged, putting them in a dangerous situation.
