Methyl salicylate, identified as primary odorant of a specific receptor neuron type, inhibits oviposition by the moth Mamestra brassicae L. (Lepidoptera, noctuidae).

abstract：:Ability to perceive the bitter compound phenylthiocarbamide (PTC) is inherited via a dominant "taster" allele of the TAS2R38 gene, whereas inability is inherited via a recessive "non-taster" allele. This raises a question: Is the non-taster allele functionless, or does it mediate perception of compounds other than PTC...
