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.

Raising spring mason bees is a growing trend among backyards across the country.
Recently, local news station King 5 visited Crown Bees headquarters to learn about our mason bees and how they are a part of a novel garden to farm to table movement.
Native hole-nesting bees, just like any creature, have their own set of diseases and pests that, when left unchecked, can harm or kill them. Nesting holes should be opened once a year to remove diseases like chalkbrood (a deadly fungal infection) and pests like pollen mites (they eat the pollen loaf before the larvae can). At the very least, fresh nesting holes should be provided every year.
