... for its host have been uncovered, the role of taste has been much less examined. We found that D. sechellia has reduced taste and feeding aversion to bitter compounds and host fatty acids that are aversive to D. melanogaster and D. simulans . The loss of aversion to canavanine, coumarin, and fatty acids...

...Sara Comesaña; Marta Conde-Sieira; Cristina Velasco; José L. Soengas; Sofia Morais ABSTRACT To assess the putative role of taste and pre-absorptive sensing of amino acids in food intake control in fish, we carried out an oral administration with l -leucine, l -valine, l -proline or l -glutamic acid...

... of their behavioral impact on Drosophila melanogaster larvae. Rhodiola rosea root samples have an attractive smell and taste to the larvae, and exert a rewarding effect. This rewarding effect was also observed for R. rosea root extracts, and did not require activity of dopamine neurons that mediate known rewards...

...Carolina E. Reisenman; Kristin Scott ABSTRACT Insects use multiple sensory modalities when searching for and accepting a food source, in particular odor and taste cues. Food-derived odorants are generally involved in mediating long- and short-range attraction. Taste cues, in contrast, act directly...

.... These flies ingested amino acids even when they were replete with glucose. The proboscis extension reflex to particular amino acids was induced only in amino-acid-deprived flies. Our findings indicate that the sensitivity of labellar taste cells to amino acids may change when flies are deficient in amino acid...

... response to sugars is to mask the taste of noxious compounds, which abound in host plants of M. sexta . We compared 10 s biting responses to water with those to mixtures of a noxious compound [caffeine (Caf) or aristolochic acid (AA)] and various combinations of sugars [i.e. sucrose (Suc), glucose (Glu...

...S. H. Rolen; J. Caprio SUMMARY Bile salts are known olfactory stimuli for teleosts, but only a single report has indicated that the taste system of a fish was sensitive to this class of stimuli. Here, gustatory responses of the channel catfish, Ictalurus punctatus , to four bile salts that included...

.... This defect in food intake regulation is partly based on the action of Takeout on taste neurons, because the sensitivity of to 1 gustatory neurons to sugars does not increase after starvation, as in wild-type neurons. This lack of regulation is also evident at the locomotor activity, which normally increases...

... with sucrose reward. It should be noted, however, that salivary neurones are activated in response to both appetitive (sucrose) and aversive (saline) taste stimuli ( Fig. 5 ). Moreover, the magnitude of responses of salivary neurones to vanilla odour did not differ from that to peppermint odour before training...

For example, FRU might appetitively sensitize larvae and lead to an increased dark preference ('this tastes good - go into this substrate'), whereas QUI or NaCl might decrease dark preference...
