E-Noses Detect Emerald Ash Borer Larvae

Electronic noses are sensitive to a vast suite of volatile organic compounds that every living organism emits. A new USDA Forest Service study shows that e-noses can detect emerald ash borer (Agrilus planipennis) larvae lurking under the bark – an early, noninvasive detection method. “The results were quite spectacular,” says Dan Wilson, a research plant…  More 

E-Noses Detect Disease in Plants, Animals & Humans

The fragrance of a rose comes from volatile organic compounds. Living plants, animals, humans, and even inanimate objects emit complex mixtures of VOCs. VOC mixtures are so distinctive that new words are used to describe them: volatilome, breathprint, and smellprint. “There are over 2,000 VOCs in a person’s breath,” says USDA Forest Service scientist Dan…  More 

Electronic Noses and Forests

What if a machine could detect insects and diseases in living trees or help prevent log theft and illegal logging by tracking individual logs from the forest to the lumberyard? What about a machine that researchers could use to identify and understand the ecological roles of microorganisms, insects and other invertebrates that live in and…  More
