Aiming to unravel how animals perceive odors, a variety of neurophysiological techniques are used today. For olfactory stimulation, odors are commonly incorporated into a constant airstream that carries odor molecules to the receptor organ (air-delivered stimulation). Such odor delivery works well for odors of high volatility (naturally effective over long distances) but less or not at all for ...

The biodegradation of polycyclic aromatic hydrocarbon pollutants is constrained, in part, by their solid physical state and very low water solubility. Searching for ways to overcome these limitations, we isolated from soil a bacterium capable of growing on pyrene as a sole source of carbon and energy. Acid-fast stain, morphology, and fatty acid profile identified it as a Mycobacterium sp. In a ...

Pheromones, Sex Attractant, (Z)-9-dodecenyl Acetate, Olfactory Receptors, Choristoneura muri­ nana, Tortricidae Traps baited with 100 ^g (Z)-9-dodecenyl acetate and 10|ig (Z)-ll-tetradecenyl acetate are highly effective in attracting C. murinana males at varying population densities. The attractive mixture was established by electrophysiological and Field screening studies combined with chemica...
