Testing <em>Drosophila</em> Olfaction with a Y-maze Assay
2014
Detecting signals from the environment is essential for animals to ensure their survival. To this aim, they use environmental cues such as vision, mechanoreception, hearing, and chemoperception through taste, via direct contact or through olfaction, which represents the response to a volatile molecule acting at longer range. Volatile chemical molecules are very important signals for most animals in the detection of danger, a source of food, or to communicate between individuals. Drosophila melanogaster is one of the most common biological models for scientists to explore the cellular and molecular basis of olfaction. In order to highlight olfactory abilities of this small insect, we describ…
Role of odorant-binding proteins in Drosophila melanogaster chemosensory perception
2019
Chemoperception is used by animals to detect nutritive food and avoid toxic compounds. It also allows animals to identify suitable ecological niche and mating partners. Like many other insects, Drosophila melanogaster possesses a very sensitive chemosensory ability and can detect and discriminate a wide panel of semiochemicals. Chemosensory detection is mostly mediated by olfactory and gustatory systems involving several multigene chemoreceptor families. Volatile and non-volatile chemical compounds entering the sensory organ (sensillum) must be solubilized before being transported through the hydrophilic sensillum lymph bathing the dendrites of chemosensory neurons. These perireceptor event…
