[ Watch the Video ] Repellant overwhelms their odor sensors, scaring them away In a small, narrow, temperature-controlled lab room at Vanderbilt University live some of the most deadly and dangerous animals in the world. "These are Anopheles mosquitoes that still think that they're in Central Africa. We won't tell them any different," says Laurence Zwiebel, professor of molecular biology and pharmacology. Anopheles gambiae mosquitoes can be killers. In warmer climates, the...

Scientists working in a laboratory at Vanderbilt University have potentially discovered a class of insect repellent that is 1000 times more effective than DEET and works against all types of insects. "It wasn't something we set out to find," said David Rinker, a graduate student who performed the study in collaboration with graduate student Gregory Pask and post-doctoral fellow Patrick Jones. "It was an anomaly that we noticed in our tests." Reported in the online edition of the Proceedings...

By David F. Salisbury Origin of DEET's repellent effect confirmed It now appears that the malaria mosquito needs more than one family of odor sensors to sniff out its human prey. That is the implication of new research into the mosquito's sense of smell published in the Aug. 31 issue of the online, open-access journal Public Library of Science Biology. The experiments described in the paper provide striking new evidence that Anopheles gambiae "“ the species of mosquito that spreads...

Scientists at Vanderbilt and Yale universities have successfully transplanted most of the "nose" of the mosquito that spreads malaria into frog eggs and fruit flies and are employing these surrogates to combat the spread of the deadly and debilitating disease that afflicts 500 million people. The research is described in two complimentary papers, one published this week in the early online edition of the Proceedings of the National Academy of Sciences and the other which appeared online Feb....
