Learning, odour preference and flower foraging in moths.
Floral volatiles play a major role in plant-insect communication. We examined the influence of two volatiles, phenylacetaldehyde and alpha-pinene, on the innate and learnt foraging behaviour of the moth Helicoverpa armigera. In dual-choice wind tunnel tests, adult moths flew upwind towards both volatiles, with a preference for phenylacetaldehyde. When exposure to either of these volatiles was p...
متن کاملOdour perception: an object-recognition approach.
Object recognition is a crucial component of both visual and auditory perception. It is also critical for olfaction. Most odours are composed of 10s or 100s of volatile components, yet they are perceived as unitary perceptual events against a continually shifting olfactory background (i.e. figure-ground segregation). We argue here that this occurs by rapid central adaptation to background odour...
متن کاملIndependent Components of Odour Signals
If two independent observations or processes are measured with the same apparatus, the inherent nature of the measuring device will in many cases introduce a dependency between the two recorded processes object to inspection. In this paper a suggestion of how Independent Component Analysis (ICA) can be used to identify such device dependencies and in turn give an estimated reconstruction of the...
متن کاملResponses of foraging hedgehogs to badger odour
Enclosure and field trials were used to investigate the responses of hedgehogs, Erinaceus europaeus, to predator (badger,Meles meles) and non-predator odours. Two hypotheses were tested: (1) hedgehogs are capable of responding to badger odour; and (2) hedgehogs prefer not to forage in areas tainted with badger odour. In enclosure trials, hedgehogs almost exclusively avoided feeding at sites tai...
متن کاملIs short-term odour recognition predictable from odour profile?
Smelling an odour induces a pattern of sensations, images and memories which participate in identification. It was proposed that perceptual memory performances for odours could be inferred from the description of these olfactory representations. The subject was asked to elaborate an odour descriptor profile, and a short-term odour recognition memory task was chosen to test the individual percep...
