Different Strokes for Different Fly Folks: Study Links Reproductive Evolution of Hawaiian Flies to Environment

June 12, 2019
In a new study, UC Davis postdoctoral researcher Didem Sarikaya and her colleagues analyzed egg-laying strategies of 65 different Hawaiian Drosophila species and found that egg-laying capacities diverged in response to their unique environments, which directly affected the number of cells involved in each species’ ovarian development.

Fruit Flies Raised in Space by UC Davis Researcher Show Weakened Immunity

December 14, 2018
Deborah Kimbrell is one of first researchers to study innate immunity in fruit flies. This is one in a series of stories highlighting UC Davis’ role in space research as the country reaches the 50th anniversary of the moon landing.

Bacteria of the Flies: Tracing the Spread of Disease-Controlling Wolbachia

March 09, 2018
In a study appearing in Current Biology, Michael Turelli, distinguished professor of genetics in the Department of Evolution and Ecology, and his colleagues traced the spread of closely related Wolbachia across Drosophila fly species. They found that while the flies evolutionarily diverged tens of millions of years ago, their Wolbachia bacteria diverged only tens of thousands of years ago.

Do Zebra Stripes Confuse Biting Flies?

May 25, 2016
Zebra stripes have fascinated people for millennia, and there are a number of different theories to explain why these wild horses should be so brightly marked. A handful of laboratories around the world – including one lead by UC Davis wildlife biologist Tim Caro – have been putting these theories to the test. A new paper from Caro’s group, led by Ken Britten at the UC Davis Center for Neuroscience, puts a hole in one idea: that the stripes confuse biting flies by breaking up polarized light.
