Peripheral olfactory signaling in insects
WebJan 8, 2024 · In ants and other insects, the peripheral detection of pheromones and other chemical signals occurs principally in olfactory sensory neurons (OSNs) housed in hair-like sensilla that are distributed along the antennae and other sensory appendages (Fig. 1).OSNs express chemoreceptor gene families that include odorant receptors (ORs), ionotropic … WebMay 4, 2015 · Introduction. A sophisticated olfactory system is crucial to insects for survival and reproduction [1,2].Antennae are the primary olfactory sensors of insects, where odorant messages (such as host volatiles, pheromones, or non-host volatiles) are perceived and subsequently translated into physiological signals that ultimately influence the insect’s …
