Host Plant Odors Represent Immiscible Information Entities - Blend Composition and Concentration Matter in Hawkmoths
Host plant choice is of vital importance for egg laying herbivorous insects that do not exhibit brood care. Several aspects, including palatability, nutritional quality and predation risk, have been found to modulate host preference. Olfactory cues are thought to enable host location. However, experimental data on odor features that allow choosing among alternative hosts while still in flight a...
متن کاملThe color of odors.
The interaction between the vision of colors and odor determination is investigated through lexical analysis of experts' wine tasting comments. The analysis shows that the odors of a wine are, for the most part, represented by objects that have the color of the wine. The assumption of the existence of a perceptual illusion between odor and color is confirmed by a psychophysical experiment. A wh...
متن کاملEffects of plant-derived odors on sleep-wakefulness and circadian rhythmicity in rats.
Plant-derived odorants promote good feeling, refresh spirits and sometimes relieve various stresses in humans. Physiological and psychological effects of plant-derived volatile chemicals have long been acknowledged in folk medicine and aromatherapy. Recent evidence from animal experiments suggests that these plant-derived chemicals affect various animal behaviors via modulating neural or humora...
متن کاملA Female-Biased Odorant Receptor from Apolygus lucorum (Meyer-Dür) Tuned to Some Plant Odors
Apolygus lucorum (Meyer-Dür) (Hemiptera: Miridae) is a serious pest of cotton, jujube, grape and many other crops around the world. Understanding how olfactory information directs this insect to its host plants may provide environment-friendly approaches to the control of its population in agriculture. In our study, we cloned an odorant receptor gene, AlucOR46, that was specifically expressed i...
متن کاملTwo minds about odors.
I t has long been suggested that synchronous fast oscillations in central sensory systems facilitate formation of neural assemblies that represent sensory objects. This hypothesis derives from the olfactory system, where odorevoked fast oscillations of 40 Hz and above in the local field potential of the mammalian olfactory bulb (OB) were first reported by Adrian (1). Similar oscillations ( 20 H...
