Tests for attraction to prey and predator avoidance by chemical cues in spiders of the beech forest floor [PDF]
, 2012 Spiders leave draglines, faeces and other secretions behind when traveling through their microhabitat. The presence of these secretions may unintentionally inform other animals, prey as well as predators, about a recent and possible current predation ...

Brazilian Archives of Biology and Technology, 2009 Several synthetic and commercial analogs of 1,4-dimethoxybenzene, a kairomone of Diabrotica speciosa, along with other compounds already shown to be attractive to other species of Diabrotica, were tested as attractant to D. speciosa.

The impact of diel vertical migration on fatty acid patterns and allocation in Daphnia magna [PDF]
PeerJ, 2020 In freshwater zooplankton diel vertical migration (DVM) is a widespread predator-avoidance behavior that is induced by kairomones released from fish. Thereby zooplankton reduces predation by fish by staying in deep and dark colder strata during daytime ...

Le potentiel de l’écologie chimique dans la lutte contre les insectes nuisibles [PDF]
, 1993 En nature, plusieurs organismes vivants émettent des substances chimiques médiatrices (infochimiques) lorsqu'ils créent des liens complexes et variés entre les individus de la même espèce ou d'espèces différentes. Dans cet article, nous décrivons comment

Field Attraction of the Vine Weevil Otiorhynchus sulcatus to Kairomones [PDF]
Journal of Economic Entomology, 2012 Root weevils in the genus Otiorhynchus are cited as one of the most important pests in the major nursery and small fruit production areas throughout the United States, western Canada, and northern Europe. A major problem in combating weevil attack is monitoring and timing of control measures.

European Journal of Entomology, 2014 Predator searching efficiency increases in response to a variety of environmental cues associated with its prey. The sugary excretion of aphids (honeydew) has been found to act as a prey-associated cue for many aphid natural enemies. In the present study,

Oviposition in the blood-sucking insect Rhodnius prolixus is modulated by host odors [PDF]
, 2015 Background: Triatomine bugs are blood-sucking insects, vectors of Chagas disease. Despite their importance, their oviposition behavior has received relatively little attention. Some triatomines including Rhodnius prolixus stick their eggs to a substrate.

5α-cyprinol sulfate, a bile salt from fish, induces diel vertical migration in Daphnia
eLife, 2019 Prey are under selection to minimize predation losses. In aquatic environments, many prey use chemical cues released by predators, which initiate predator avoidance. A prominent example of behavioral predator-avoidance constitutes diel vertical migration

Entomologia Experimentalis et Applicata, EarlyView.We developed and field‐validated a fully automated trap for Cydia pomonella monitoring, combining a camera with a YOLOv8 object‐detection model for remote insect identification. In controlled laboratory validation, the model showed strong performance (precision 0.77, recall 0.83), with moderate reductions under field conditions. Across six experiments,
