Effect of volatiles from herbivores and herbivore-damaged rice plants on the behavioral selection of parasitoid Cotesia ruficrus haliday

浙江大学学报. 农业与生命科学版, 2003
Cotesia ruficrus is one of the main larval parasitoids of the rice striped-stemborer (SSB) Chilo suppressalis and rice leaf folder (RLF) Cnaphalocrocis medinalis in rice field habitat.

Female-induced increase of host-plant volatiles enhance specific attraction of aphid male Dysaphis plantaginea (Homoptera: Aphididae) to the sex pheromone

, 2009
All aphid species studied so far share the same sex pheromone components, nepetalactol and nepetalactone. Variation by different enantiomers and blends of the two components released by different aphid species are limited and can only partially explain ...

Variation Patterns of the Volatiles during Germination of the Foxtail Millet (Setaria Italic): The Relationship between the Volatiles and Fatty Acids in Model Experiments

Molecules, 2020
Functional and nutritional compounds are increased during foxtail millet germination while bad smell is produced due to the fatty acid oxidation. To eliminate the unpleasant aroma, the origins of the volatiles must be known.

Sensing the Danger Signals: cis-Jasmone Reduces Aphid Performance on Potato and Modulates the Magnitude of Released Volatiles [PDF]

, 2020
In response to herbivory, plants synthesize and release variable mixtures of herbivore-induced plant volatiles (HIPVs) as indirect defense traits. Such induction of indirect plant defense can also be “switched on” by certain chemicals known as priming ...

A simple joint model for returns, volatility and volatility of volatility

Journal of Econometrics, 2023
We propose a model that allows for conditional heteroskedasticity in the volatility of asset returns and incorporates current return information into the volatility nowcast and forecast. Our model can capture all stylised facts of asset returns even with Gaussian innovations and is simple to implement.

The herbivore-induced plant volatile methyl salicylate negatively affects attraction of the parasitoid Diadegma semiclausum

, 2010
The indirect defense mechanisms of plants comprise the production of herbivore-induced plant volatiles that can attract natural enemies of plant attackers. One of the often emitted compounds after herbivory is methyl salicylate (MeSA).

An Indirect Defence Trait Mediated through Egg-Induced Maize Volatiles from Neighbouring Plants. [PDF]

, 2016
Attack of plants by herbivorous arthropods may result in considerable changes to the plant's chemical phenotype with respect to emission of herbivore-induced plant volatiles (HIPVs).
