Co-localization of insect olfactory sensory cells improves the discrimination of closely separated odour sources
Original language description
The sense of smell is crucial for fitness of most animals, enabling them to find mates, food and egg laying sites and to stay away from danger. Hence, odour molecules are detected by sensitive and specific olfactory sensory neurons (OSNs). In insects, the OSNs are stereotypically grouped into olfactory sensilla located mainly on the antennae. The functional significance of this co-localization principle is poorly understood, but it has been hypothesized that it allows for coincidence detection of odourfilaments, improving discrimination of closely separated odour sources. 2. Using an insect in its natural environment, we conducted the first experimental test of the hypothesis. We manipulated the distance between odour sources of an attractive pheromone and either of two host-derived attraction antagonists (1,8-cineole and verbenone) and investigated the effect on trap catches of the bark beetle, Ips typographus (Coleoptera). 1,8-Cineole is detected by an OSN co-localized with an OSN f
