Rapid habituation by mosquito larvae to predator kairomones [PDF]

open access: yesJournal of Vector Ecology, 2014
Larvae of some species of mosquitoes have been shown to respond to water-borne kairomones from predators by reducing bottom-feeding and replacing it with surface filter-feeding, which uses less movement and is thus less likely to attract a predator. However, if no predator attack takes place, then it would be more efficient to use a risk allocation ...

Migrating Daphnia have a memory for fish kairomones

Marine and Freshwater Behaviour and Physiology, 1995
Kairomones from juvenile perch (Perca fluviatilis) enhance phototactic descent of Daphnia to the hypolimnion of lakes following upon light intensity increases at dawn. Kairomones are not present in the hypolimnion and ascent in the evening might be insufficient for the animals to reach the epilimnion again.

Identification and bioassay of kairomones forHelicoverpa zea

Journal of Chemical Ecology, 1996
Hexane extracts of leaves of 307 accessions from 73 host plant species ofHelicoverpa zea were analyzed by gas chromatography (GC) and used forH. zea oviposition and neonate larvae orientation bioassays. The gas chromatographic (GC) retention times of compounds statistically associated with behavioral activity were identified by correlation of GC peak ...
