Allelochemical Communication in Vertebrates: Kairomones, Allomones and Synomones
Cells Tissues Organs, 2006Communication between different species by means of chemicals (allelomones) is widespread among prokaryotes, plants and invertebrates. This study reviews data suggesting that allelochemically mediated communication also exists among vertebrates. The work aims to provide a concise, interdisciplinary review of communication mediated by infochemicals ...

Specific Foraging Kairomones Used by a Generalist Parasitoid
Journal of Chemical Ecology, 2003In general, it is assumed that generalist natural enemies do not innately use specific cues for the location of their host or prey species. This hypothesis was tested using naïve females of the generalist parasitoid Lariophagus distinguendus Förster and two of its hosts, larvae of the lesser grain borer Rhyzopertha dominica (F.) and of the granary ...

Crustacean peptide and peptide-like pheromones and kairomones
Peptides, 2004Crustacean peptide pheromones, kairomones, and substituted amino sugar kairomones are reviewed from a historical perspective. These crustacean information molecules are secondary functions of structural polymers. They are partial hydrolysis products, generated usually by the action of trypsin-like enzymes on proteins, and glycosidase enzymes on ...

Allomones and Kairomones: Transspecific Chemical Messengers
BioScience, 1970The currently lively field of chemical ecology is uncovering a surprising variety of ways in which organisms interact through chemical agents. The term pheromone, coined only recently (Karlson and Butenandt, 1959), but already widely accepted, applies to any substance produced by an organism that serves, upon contacting another member of the same ...

The Acrolepiopsis assectella silk cocoon: kairomonal function and chemical characterisation [PDF]
Journal of Insect Physiology, 2004 Two soluble sericin-like polypeptides, B1 and B2, from leek moth (Acrolepiopsis assectella) cocoons trigger host-acceptance behaviour in the parasitoid, Diadromus pulchellus (Proc. Roy. Soc. London B 269 (2002) 1879). We found that these polypeptides were particularly cysteine-rich and lost their ability to trigger host-acceptance behaviour after being

Kairomone response inThanasimus predators to pheromone components ofIps typographus
Journal of Chemical Ecology, 1981Thanasimus formicarius (L.) responds to racemic ipsdienol and ipsenol and less to (S)-cis-verbenol. All three are pheromone components in several bark beetles of the genusIps. Synergistic effects appeared when the components were combined. Methylbutenol alone, the specific pheromone component ofIps typographus, elicited no response, but synergestic ...

Facing multiple enemies: parasitised hosts respond to predator kairomones
Oecologia, 2002During their lifetime most organisms are exposed to various enemies influencing their victims in multiple direct and indirect ways. Most studies concentrate on the effects of one enemy at a time, thereby not taking into account that in nature organisms are often simultaneously exposed to more than one enemy.

Kairomonal Attractants for Acalymma vittatum (Coleoptera: Chrysomelidae)
Environmental Entomology, 1990In the absence of contact and visual stimuli, significant numbers of adult striped cucumber beetles, Acalymma vittatum (F.), were caught on veiled sticky cups containing either squash seedlings or blossoms. The role of volatile kairomones in host finding was further demonstrated by the attraction of A.

Hydrobiologia, 2003
Life history traits of Daphnia galeata clones were affected differently by kairomones exuded by two species of fish. The exposure to Gasterosteus kairomone resulted in an increase in population intrinsic rate of increase and body growth rate relative to the exposure to Perca kairomone.

Olfactory Sensitivity of Tsetse to Phenolic Kairomones
International Journal of Tropical Insect Science, 1992Behavioural and electrophysiological (EAG) studies were undertaken to determine the olfactory selectivity of the antennae of Glossina morsitans morsitans Westwood and Glossina pallidipes Austen to phenolic kairomones. Responses of both species to 3-aIkylphenols increased as the alkyl chain increased from one carbon atom to three, while the opposite ...
