Insect olfaction Insect olfaction Insect olfaction refers to the function of chemical receptors that enable insects to detect and identify volatile compounds for foraging, predator avoidance, finding mating partners (via pheromones) and locating oviposition habitats. Thus, it is the most important sensation for insects. Most important insect behaviors must be timed perfectly which is dependent on what they smell and when they smell it. For example, olfaction is essential for hunting in many species of wasps, including "Polybia sericea". The two organs insects primarily use for detecting odors are the antennae and specialized mouth parts called the maxillary palps. However, a recent
Pharaoh ant recommended method to eliminate pharaoh ants is by the use of baits attractive to the species. Modern baits use insect growth regulators (IGRs) as the active substance; the ants are attracted to the bait by its food content, and take it back to the nest. Over a period of weeks the IGR prevents the production of worker ants and sterilizes the queen. Renewing the baits once or twice may be necessary. Pharaoh ants have also been exterminated by placing baits of ground liver mixed with boric acid in places where the ants forage. Pharaoh ant The pharaoh ant ("Monomorium pharaonis")
