The buzz around beer
Date:11/17/2011

RIVERSIDE, Calif. Ever wondered why flies are attracted to beer? Entomologists at the University of California, Riverside have, and offer an explanation. They report that flies sense glycerol, a sweet-tasting compound that yeasts make during fermentation.

"Insects use their taste system to glean important information about the quality and nutritive value of food sources," said Anupama Dahanukar, an assistant professor of entomology, whose lab conducted the research. "Sugars signal high nutritive value to flies, but little is known about which chemical cues flies use for food sources that are low in sugar content such as beer."

Dahanukar's lab examined the feeding preference of the common fruit fly for beer and other products of yeast fermentation, and found that a receptor (a protein that serves as a gatekeeper) that is associated with neurons located in the fly's mouth-parts is instrumental in signaling a good taste for beer.

The receptor in question is Gr64e. Once a fly has settled on beer, Gr64e detects glycerol and transmits this information to the fly's neurons, which then influences the fly's behavioral response.

Dahanukar explained that flies use other receptors in their sensory organs to find food from a distance.

"Taste becomes important only after the fly makes physical contact with food," she said. "A fly first locates food sources using its odor receptors crucial for its long-range attraction to food. Then, after landing on food, the fly uses its taste system to sample the food for suitability in terms of nutrition and toxicity."

Dahanukar, a member of UCR's Institute for Integrative Genome Biology, explained that taste receptors also come into play when a female fly has to locate a suitable site for l
