Fruit flies help Yale scientists sniff out new insect repellents
Date:9/22/2010

By following the "nose" of fruit flies, Yale scientists are on the trail of new insect repellents that may reduce the spread of infectious disease and damage to agricultural crops. That's because they've learned for the first time how a group of genes used to differentiate smells is turned on and off, opening new possibilities for insect control. Just as in new drug development, researchers can target these or similar genes in other insects to create substances that make crops and people "invisible" to insect antennae. Without the ability to smell correctly, the insects are far less likely to attack a person or plant, as is the case with mosquitoes whose ability to smell lactic acid is disrupted by the active ingredient in insect repellents, DEET. This finding is reported in the September 2010 issue of the journal GENETICS (http://www.genetics.org).

According to Carson Miller, a researcher involved in the work from the Department of Molecular, Cellular and Developmental Biology at Yale University, "One of the fundamental questions in biology is, 'how does a cell choose which genes it should turn on and which genes it should turn off?' By studying this question in odor-sensitive neurons of fruit flies, we hope to learn how cells make these choices, as well as to develop more effective odor-based insect repellents."

The scientists studied four genes from a group of odor receptor genes in the fruit fly. These genes afford flies the ability to detect different scents. Pieces of DNA in front of these genes contained enough information to tell the fly to turn on these genes in specific cells of the antenna. Miller made an artificial reporter gene that used the regulatory DNA in front of an Odor receptor gene to control a test gene that could be easily monitored for expression. An entire set of such reporter genes were created, each containing less of the regulatory DNA. The goal was to determine how s
