Herbivore kairomones affect germination speed, seedling growth, and herbivory. [PDF]

Oecologia
Abstract Seeds and seedlings are particularly vulnerable to herbivory. Unlike mature plants, which can wait until herbivory is experienced to induce defense, seeds and seedlings face mortality if they wait. Slug mucus functions as a kairomone, a non-attack-related substance emitted by consumers that is detected by

Change in phenotypic plasticity of a morphological defence in Daphnia galeata (Crustacea: Cladocera) in a selection experiment

Journal of Limnology, 2007
Some water fleas Daphnia change their head morphology to reduce predation risk in response to chemical substances (kairomones) released from larvae of the invertebrate predator Chaoborus (Insecta: Diptera).

Daphnia magna responses to fish kairomone and chlorpromazine exposures

Chemico-Biological Interactions, 2020
To avoid being preyed, organisms must be able to identify predatory threats by sensing molecules released by predators (kairomones), and to employ effective strategies to prevent detection by predators. Furthermore, in the wild, organisms are also exposed to chemicals that may alter their behavioral traits, such as neuroactive pharmaceuticals ...

Tracking Short-Range Attraction and Oviposition of European Grapevine Moths Affected by Volatile Organic Compounds in a Four-Chamber Olfactometer

Insects, 2020
The identification of volatile organic compounds (VOCs) leading to short-range attraction and oviposition of the European grapevine moth Lobesia botrana and European grape berry moth Eupoecilia ambiguella (Lepidoptera: Tortricidae) is crucial in order to

Proteomic analysis of Daphnia magna hints at molecular pathways involved in defensive plastic responses [PDF]

, 2014
Background: Phenotypic plasticity in defensive traits occurs in many species when facing heterogeneous predator regimes. The waterflea Daphnia is well-known for showing a variety of these so called inducible defences.

Imidacloprid pesticide alters anti-predator responses in a water flea (Daphnia sinensis)

Water Biology and Security
Organisms develop inducible defense strategies to combat predators, altering behaviour, morphology, and life history to minimize predation risk.

PHEROMONE SYNERGISTS AS CO-ATTRACTANT FOR OLFACTORY TRAPPING OF SCAPANES AUSTRALIS BSDV. (COLEOPTERA: SCARABAEIDAE) PEST OF COCONUT IN PAPUA NEW GUINEA

CORD, 2004
Olfactory trapping of Scapanes australis is being studied to develop it to complement existing control methods. Components required were traps, pheromone and pheromone synergist.

Morphological and Histological Features of the Vomeronasal Organ in African Pygmy Hedgehog (Atelerix albiventris)

Animals, 2021
The vomeronasal organ (VNO) detects specific chemicals such as pheromones and kairomones. Hedgehogs (Eulipotyphla: Erinaceidae) have a well-developed accessory olfactory bulb that receives projections from the VNO, but little is known about the hedgehog ...

Cathemerality and Insensitivity to Predatory Fish Cues in Pond Isopods (Caecidotea communis)

Hydrobiology
Because animals threatened by visually oriented predators may respond in sun-lit daytime but not at night, invertebrate responses to predatory challenges may yield varying results based on the time period within the 24 h daily cycle. We predicted that in
