What is a semiochemical?
A semiochemical, from the Greek σημεῖον ( semeion ), meaning "signal", is a chemical substance or mixture released by an organism that affects the behaviors of other individuals.
What are the two types of semiochemical communication?
Semiochemical communication can be divided into two broad classes: communication between individuals of the same species (intraspecific) or communication between different species (interspecific).
How do insects detect semiochemicals?
Perception of semiochemicals by insects is remarkably selective. Detection of target compounds involves highly specialized, extremely sensitive sensilla that are situated along sensory hairs on the insect’s antenna. The sensilla carry odorant receptor neurons (ORNs) whose odorant receptors (ORs) are isolated by an aqueous sensillar fluid (lymph).
