Winter Wonderland of Seminars
Assistant professors Louie Yang and Joanna Chiu have just announced the UC Davis Department of Entomology's list of seminar speakers for the winter quarter.
And what a list it is!
It's a winter wonderland of speakers. And the good news is, most will be webcast and then posted on UCTV, compliments of a project led by professor James R. Carey of the UC Davis Department of Entomology.
The seminars begin Wednesday, Jan. 11 and will continue every Wednesday through March 21. All will be held from 12:10 to 1 p.m. in 122 Briggs Hall, Klieber Hall Lane.
One subject that's sure to attract a lot of attention: pollen and pollinators. We're looking forward to hearing T’ai Roulston, research associate professor and curator, State Arboretum of Virginia, speak Feb. 1 on "Pollen as a Resource for Pollinators: What Governs Quality?"
In fact, we're looking forward to all of the speakers!
Here's the line-up:
Jan. 11: Denise Ferkey, assistant professor, State University of New York (SUNY), Buffalo, will speak on "Regulation of Chemosensory Signaling in C. elegans."
Hosts: Valerie Williamson, professor of nematology, and Ed Lewis, professor of nematology and entomology and acting chair of the UC Davis Department of Entomology.
Jan. 18: Anurag Agrawal, professor of ecology at Cornell University, Ithaca, N.Y., will speak on "Evolutionary Ecology of Plant Defenses."
Host: Andrew Merwin of the Michael Parrella lab.

Petal Pushers
Honey bees and daisies are made for each other.
The white petals and the golden centers seem incomplete without the presence of buzzing bees.
Today we watched a pollen-packin' honey bee, with a pollen load the color of autumn pumpkins, work a daisy.
No matter that it was Friday the 13, supposedly an unlucky day. It was a lucky day for her as she foraged on the daisy and collected pollen her colony. The pollen will provide not only protein, but minerals and vitamins for the developing larvae.
Honey bee expert Norman Gary, emeritus professor of apiculture at the University of California, Davis and the author of Honey Bee Hobbyist: the Care and Keeping of Bees, says that during an entire year, "a typical bee colony gathers and consumes 77 pounds of pollen."
That's a lot of pollen! This little bee (below) did her part.

Peachy Keen
California peach blossoms are peachy keen.
Especially when honey bees are foraging.
The pink pastel blossoms, powder blue sky, and golden honey bees...yes, California peach orchards are blooming.
Is it too soon to think about peach cobbler?

Heavy Load
Pollen-Packin' Carpenter Bee
Carpenter bees pack pollen, too.
A carpenter bee (Xylocopa tabaniformis orpifex) visiting our gaura last weekend was packing bright yellow pollen, a sharp contrast against her black body.
Native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, Davis, said that "the large triangular pollen grains of this and other Onagraceae are held together in strings by viscin threads. You can see this on the anther above the bee’s head. This makes it a challenge for some bees to neatly pack this pollen, but helps pollen to get draped on the plant stigma."
The UC Davis Department of Entomology website includes information on three species of carpenter bees commonly found in California.

Tiptoeing Through the Tulips
Honey bees don’t like tulips, right?
Right.
You don't plant tulips to attract bees, and you don't attract bees with tulips.
They prefer such bee friendly plants as lavender, salvia, catmint, sedum, cherry laurels and tower of jewels—not to mention fruit, almond and vegetable blossoms.
But last weekend, a lone bee—probably a confused lone bee—buzzed around our tulips in the back yard and then dropped inside to roll in the pollen.
She stayed inside the tulip for about five minutes. When she emerged, a layer of gold dust clung to her.
Bees don't like tulips? This one did!
