“…significantly reduce their movement when exposed to chemicals from injured conspecifics: a response that reduces exposure to visual predators (Huryn & Chivers 1999). Aphids stop feeding and walk away from feeding sites in response to the synthetic alarm pheromone (E )-β-farnesene (Shah et al 1999). Another synthetic alarm pheromone, citral, triggers an active dispersal of four mite species: Carpoglyphus lactis, Lardoglyphus konoi, Tyrophagus putrescentiae, and Aleuroglyphus ovatus (Matsumoto et al 1998).…”

Food webs are overlaid with infochemical webs that mediate direct and indirect interactions. The infochemicals may result in shifts in trait values, which affect the strength of species interactions. As a consequence, population dynamics and evolutionary changes can be affected. Chemical information can mediate the interactions between animals and their resources, competitors and enemies. Of all chemical information gathered by animals, cues about predation risk are of special significance because predation risk usually has important and immediate consequences on fitness. In this paper we selectively review the role of chemical information in enemy avoidance by arthropods. Arthropods not only constitute important components of food webs, being the largest group in numbers and species diversity; they also make excellent models for ecological studies. We discuss the evidence, the key mechanisms, and the trade-offs involved in chemical detection of enemies by potential arthropod prey. Further, we address the variation in prey responses and the evidence for learning in avoiding enemies by arthropods. Finally, we identify and prioritize major questions to be tackled by future studies.

“…In the wild, preys detect the presence of their predators and avoid being eaten through the detection of predator scents and of their stressed or injured conspecifics via alarm pheromone sensing [ 4 , 63 – 66 ]. Here, we found three TAS2Rs expressed in the mouse GG neurons that might be implicated in this sensory deciphering.…”

Alarm pheromone and kairomone detection via bitter taste receptors in the mouse Grueneberg ganglion

et al. 2018

BackgroundThe mouse Grueneberg ganglion (GG) is an olfactory subsystem specialized in the detection of volatile heterocyclic compounds signalling danger. The signalling pathways transducing the danger signals are only beginning to be characterized.ResultsScreening chemical libraries for compounds structurally resembling the already-identified GG ligands, we found a new category of chemicals previously identified as bitter tastants that initiated fear-related behaviours in mice depending on their volatility and evoked neuronal responses in mouse GG neurons. Screening for the expression of signalling receptors of these compounds in the mouse GG yielded transcripts of the taste receptors Tas2r115, Tas2r131, Tas2r143 and their associated G protein α-gustducin (Gnat3). We were further able to confirm their expression at the protein level. Challenging these three G protein-coupled receptors in a heterologous system with the known GG ligands, we identified TAS2R143 as a chemical danger receptor transducing both alarm pheromone and predator-derived kairomone signals.ConclusionsThese results demonstrate that similar molecular elements might be used by the GG and by the taste system to detect chemical danger signals present in the environment.Electronic supplementary materialThe online version of this article (doi:10.1186/s12915-017-0479-y) contains supplementary material, which is available to authorized users.

“…Typical responses range from the cessation of feeding and removal of the stylet from host plant tissues to walking, jumping, or falling away from the source of emission (Edwards et al, 1973;Wientjens et al, 1973;Phelan et al, 1976;Nault, 1977a, b, 1978;Roitberg and Myers, 1978;Wohlers, 1980;Clegg and Barlow, 1982;Chau and Mackauer, 1997;Losey and Denno, 1998;Shah et al, 1999;Braendle and Weisser, 2001). In the sugar-cane woolly aphid, Ceratovacuna lanigera Zehntner (Homoptera, Pemphigidae), the alarm pheromone reportedly elicited aggressive behavior from conspecifics (Arakaki, 1989).…”

In this chapter we discuss our current understanding of chemical alarm signaling in a variety of animal groups (including social and pre-social insects, marine invertebrates, fish, and mammals) and in plants. We also briefly discuss the exploitation of alarm pheromones as foraging cues for natural enemies. We conclude with a brief discussion of the potential exploitation of alarm signaling to achieve the applied goal of managing pest species.
