Whereas olfactory learning allowing memory of nutritious plants is well demonstrated, little is known about learning and memory of toxic items in adult lepidopterans. Moths may use bitter substances to detect and possibly learn to avoid noxious plants. We have studied the physiological and behavioural effects of two bitter substances, quinine and sinigrin, on the moth Heliothis virescens. Electrophysiological recordings showed responses to both compounds in gustatory receptor neurons on the antennae. The response patterns suggested a peripheral discrimination between quinine and sinigrin. We evaluated their putative aversive effect in an appetitive conditioning context where the moths learned to associate an odour with sucrose. We first aimed at enhancing olfactory conditioning of the proboscis extension response by testing the effect of the sucrose concentration on acquisition, retention and extinction. 2 mol l\u20131 and 3 mol l\u20131 sucrose concentration gave similar acquisition, retention and extinction performances. Experiments involving pre-exposure or facilitated extinction with an odour paired with quinine, sinigrin or no tastant showed a latent inhibitory effect,as well as an aversive effect of quinine and, to a lesser extent, of sinigrin. The results suggested that the two tastants may act as negative reinforcers in H. virescens.<\/jats:p>","DOI":"10.1242\/jeb.004283","type":"journal-article","created":{"date-parts":[[2007,6,29]],"date-time":"2007-06-29T17:44:03Z","timestamp":1183139043000},"page":"2563-2573","source":"Crossref","is-referenced-by-count":29,"title":["Effects of two bitter substances on olfactory conditioning in the moth <i>Heliothis virescens<\/i>"],"prefix":"10.1242","volume":"210","author":[{"given":"Kari","family":"J\u00f8rgensen","sequence":"first","affiliation":[{"name":"Neuroscience Unit, Department of Biology, Norwegian University of Science and Technology, Trondheim, Norway,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marit","family":"Stranden","sequence":"additional","affiliation":[{"name":"Neuroscience Unit, Department of Biology, Norwegian University of Science and Technology, Trondheim, Norway,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Christophe","family":"Sandoz","sequence":"additional","affiliation":[{"name":"Research Center on Animal Cognition, University Paul Sabatier, Toulouse,France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Randolf","family":"Menzel","sequence":"additional","affiliation":[{"name":"Department of Biology, Freie Universita\u0308t, Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanna","family":"Mustaparta","sequence":"additional","affiliation":[{"name":"Neuroscience Unit, Department of Biology, Norwegian University of Science and Technology, Trondheim, Norway,"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","reference":[{"key":"2021042510572592200_REF1","doi-asserted-by":"crossref","unstructured":"Abramson, C.
