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 ...

Host-specific recognition kairomone for the parasitoidMicroplitis croceipes (Cresson)
Journal of Chemical Ecology, 1995A water-extractable host recognition kairomone in frass of corn earworm,Helicoverpa zea Boddie (Lepidoptera: Noctuidae), host larvae stimulates antennation by females of the parasitoidMicroplitis croceipes Cresson (Braconidae: Hymenoptera). In addition, when the wasps contact water extracts of host frass they will subsequently fly in a flight tunnel to

Kairomones as Pigeonpea Resistance Factors Against Heliothis armigera
International Journal of Tropical Insect Science, 1985The differential attraction by 2 pigeonpea cultivars has been tested through the oviposition behaviour of Heliothis armigera females in a standardized laboratory assay. Seedlings of a susceptible variety (PPE-50) are under choice conditions significantly more attractive at a distance, and without contact allowed other than those of the resistant ...

Kairomone stimulates increased probes and host stings in a cleptoparasitoid
Physiological Entomology, 2006Abstract. Eupelmus vuilleti acts as a cleptoparasitoid when encountering a host parasitized by Dinarmus basalis . The encounter of a parasitized host stimulates an increasing number of ovipositor probes directly above the parasitized host, an ...
