Silicon and Plant Natural Defenses against Insect Pests: Impact on Plant Volatile Organic Compounds and Cascade Effects on Multitrophic Interactions

Plants, 2019
Environmental factors controlling silicon (Si) accumulation in terrestrial plant are key drivers to alleviate plant biotic stresses, including insect herbivory.

Field trials of chemical suppression of embryonic cane toads (Rhinella marina) by older conspecifics

Ecology and Evolution, 2020
Laboratory experiments have shown that the viability of embryos of the invasive cane toad (Rhinella marina) can be reduced by exposure to chemical cues from older conspecific larvae.

Putative chemical cue from Gyrodactylus-infected guppies subtly alters behaviour but prior exposure decreases parasite intensity

Parasitology, 2023
The reliance on chemical communication is well established for evading predation in aquatic systems. Only a few studies have found evidence that chemical cues released from aquatic animals infected with parasites alter behaviour.

Sight in a Clique, Scent in Society: Plasticity in the Use of Nestmate Recognition Cues Along Colony Development in the Social Wasp Polistes dominula

Frontiers in Ecology and Evolution, 2019
Nestmate recognition, i.e., the ability to discriminate nestmates from foreign individuals, is a crucial feature of insect societies, and it has been traditionally considered to be predominantly based on chemical cues. Recent empirical evidence, however,

Transcriptome Dynamics of an Oyster Larval Response to a Conspecific Cue-Mediated Settlement Induction in the Pacific Oyster Crassostrea gigas

Diversity, 2022
The molecular mechanisms underlying the conspecific cue-mediated larval settlement in Crassostrea gigas is not yet fully understood. In this study, we described and compared the transcriptomes of competent pediveligers (Pedi) and conspecific cue-induced ...

Blood cues induce antipredator behavior in Nile tilapia conspecifics. [PDF]

PLoS ONE, 2013
In this study, we show that the fish Nile tilapia displays an antipredator response to chemical cues present in the blood of conspecifics. This is the first report of alarm response induced by blood-borne chemical cues in fish.

Similar Response of a Range Expanding Dragonfly to Low- and High-Elevation Predators

Diversity, 2022
Recent range expansion of many species northward and upward in elevation suggests that the expanding species are able to cope with new biotic interactions in the leading edge.

Physical and chemical cues affect oviposition by Neoleucinodes elegantalis [PDF]

, 2010
Recognition and acceptance of a suitable host plant by phytophagous insects requires the integration of visual, physical and chemical cues. The present study investigates the host cues that a specialist insect integrates to optimize oviposition ...

Honeydew Is a Food Source and a Contact Kairomone for Aphelinus mali

Insects, 2023
Many parasitoids need to feed on sugar sources at the adult stage. Although nectar has been proven to be a source of higher nutritional quality compared to honeydew excreted by phloem feeders, the latter can provide the necessary carbohydrates for ...

The role of plant chemical cues in determining host preference in the generalist aphid parasitoid Aphidius colemani

, 2000
The host preference behaviour of the generalist aphid parasitoid Aphidius colemani was investigated using a Y-tube olfactometer. Female A. colemani showed a preference for the host-plant complex on which they had been reared, even though the same aphid ...
