Messing with the microbes within their hive-stored pollen hurts bumblebees

Wednesday, April 17, 2019 2:04:21 PM America/Los_Angeles

Of the 20,000+ bee species on Earth, only about a dozen are used by farmers in commercial agriculture, and these crucial populations of managed bees have been declining at an alarming rate. Several factors, including increased use of pesticides, habitat fragmentation, emerging diseases, and reduced genetic diversity may be responsible for such bee losses. In response to this pollinator crisis, recent conservation efforts have led to stricter regulations on insecticide use. However, other agrochemicals such as herbicides and fungicides that do not directly target insects (such as bees) continue to be applied to in-bloom crops without much scrutiny. Curiously, past research shows that while certain fungicides may pose a lower risk for adult honeybees, they appear to be quite harmful for larval bees. Such findings were somewhat unexpected, and we at the Steffan lab wanted to find out why.

4 Ways to Help Hawaii's Endangered Bees

Thursday, July 6, 2017 12:39:17 PM America/Los_Angeles

Dr. Jason Graham is the lead researcher developing conservation for the endangered Hawaiian yellow-faced bees in the Plant and Environmental Protection Sciences Department at the University of Hawaii at Mānoa. Seven species of Hawaii's yellow-faced bees were placed on the endangered species list in October 2016, these are the first species of bees to be protected and labeled as endangered.

Squash Pollinators of the Americas Survey

Tuesday, September 6, 2016 2:22:33 AM America/Los_Angeles

Dr. Jim Cane of the USDA Agricultural Research Service has recently shared with us the following excerpt of his recent work with native bees that exclusively pollinate squash. An article by Science Daily also discusses the findings showing that squash-pollinating bees migrated with the spread of squash agriculture across North America.

Mason Bees in Extension Services

Friday, June 12, 2015 12:54:04 AM America/Los_Angeles

Mason bees are wonderful additions to extension service programs. The programs can evaluate the efficiency of mason bees, learn and teach about mason bee life cycles, and make recommendations to farmers and gardeners about the ability of mason bees to pollinate in their region. Mason bees and honey bees can work together in farms and mason bees have been shown to actually improve the pollination behavior of honey bees.
