Insect olfaction gustatory, ionotropic, and olfactory receptors and “distorts” other odorants interaction with those receptors. 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
Insect repellent formerly known as Bayrepel or KBR3023), ethyl butylacetylaminopropionate (IR3535) and citriodiol (p-menthane-3,8-diol) are available. Most "natural" insect repellents such as citronella, neem oil, and herbal extracts are no longer permitted for sale as insect repellents in the EU due to their lack of effectiveness; this does not preclude them from being sold for other purposes, as long as the label does not indicate they are a biocide (insect repellent). A 2018 study found that Icaridin, in what the authors described as conservative exposure doses, is highly toxic to salamander larvae. The LC50 standard was additionally found to be completely inadequate
