Pairing an odor and taste can change ratings of the odor's perceptual and hedonic characteristics. Behavioral indices of such changes are lacking and here we measured sniffing to assess learned changes in odor liking due to pairing with sweet and bitter tastes. Participants were divided on their liking for sweetness, as well as dietary disinhibition (Three-Factor Eating Questionnaire-Disinhibit...

Although the five basic taste qualities-sweet, sour, bitter, salty and umami-can be recognized by the respective gustatory system, interactions between these taste qualities are often experienced when food is consumed. Specifically, the umami taste has been investigated in terms of whether it enhances or reduces the other taste modalities. These studies, however, are based on individual percept...

Sweet tasting foods have been found to have an analgesic effect. Therefore people might consume more sweet-tasting food when they feel pain. In Study 1, participants were randomly assigned to a pain or non-pain condition and their consumption of cheesecake was measured. Participants ate more cheesecake (a sweet-tasting food) following a painful experience than a non-painful one. In Study 2, par...

Sweet taste cells play critical roles in food selection and feeding behaviors. Drosophila sweet neurons express eight gustatory receptors (Grs) belonging to a highly conserved clade in insects. Despite ongoing efforts, little is known about the fundamental principles that underlie how sweet tastants are detected by these receptors. Here, we provide a systematic functional analysis of Drosophila...

Nematode population densities and yield of sweet corn and sweet potato as affected by the nematicide fenamiphos, in a sweet corn-sweet potato-vetch cropping system, were determined in a 5-year test (1981-85). Sweet potato was the best host of Meloidogyne incognita of these three crops. Fenamiphos 15G (6.7 kg a.i./ha) incorporated broadcast in the top 15 cm of the soil layer before planting of e...
