Researchers in the Department of Entomology,  University of California, Davis, have discovered that the fruit fly has a native odorant receptor that detects the silkworm moth's sex pheromone, and that it's "amazingly more sensitive" than the moth's odorant receptor. Their work could open research doors for insect-inspired biosensors. The odor detector or OR is a means of chemical communication that helps insects find mates.  The olfactory link between silkworm moths (Bombyx mori)...

Chemical ecologists in the Walter Leal lab at the University of California, Davis, have identified the dominant odor naturally produced in humans and birds that attracts the blood-feeding Culex mosquitoes, which transmits West Nile virus and other life-threatening diseases.  The groundbreaking research explains why mosquitoes shifted hosts from birds to humans and paves the way for key developments in mosquito and disease control. Entomology professor Walter Leal and postdoctoral...

Scientists at the University of California, Davis, have identified the dominant odor naturally produced in humans and birds that attracts the blood-feeding Culex mosquitoes, which transmit West Nile virus and other life-threatening diseases. The groundbreaking research, published this week in the early online edition of the Proceedings of the National Academy of Sciences, explains why mosquitoes shifted hosts from birds to humans and paves the way for key developments in mosquito and disease...
