Aphid alarm pheromone produced by transgenic plants affects aphid and parasitoid behavior
The alarm pheromone for many species of aphids, which causes dispersion in response to attack by predators or parasitoids, consists of the sesquiterpene (E)-β-farnesene (Eβf). We used high levels ofExpand

Response of economically important aphids to components of Hemizygia petiolata essential oil.
The essential oil of Hemizygia petiolata Ashby (Lamiaceae) contains high levels (>70%) of the sesquiterpene (E)-beta-farnesene, the alarm pheromone for many economically important aphid species. InExpand

cis-Jasmone treatment induces resistance in wheat plants against the grain aphid, Sitobion avenae (Fabricius) (Homoptera: Aphididae).
cis-Jasmone is a plant volatile known to have roles as an insect semiochemical and in inducing plant defence. It was evaluated in laboratory and field trials for control of cereal aphids. In anExpand

New roles for cis-jasmone as an insect semiochemical and in plant defense.
cis-jasmone, or (Z)-jasmone, is well known as a component of plant volatiles, and its release can be induced by damage, for example during insect herbivory. Using the olfactory system of the lettuceExpand

Winter host component reduces colonization by bird-cherry-oat aphid,Rhopalosiphum padi (L.) (homoptera, aphididae), and other aphids in cereal fields
Methyl salicylate, a volatile component ofPrunus padus, the winter host ofRhopalosiphum padi, was found to reduce colonization of the summer host by this aphid. The compound was identified by gasExpand

Phytochemicals of Brassicaceae in plant protection and human health--influences of climate, environment and agronomic practice.
In this review, we provide an overview of the role of glucosinolates and other phytochemical compounds present in the Brassicaceae in relation to plant protection and human health. Current knowledgeExpand

Exploiting semiochemicals in insect control
The present situation and future prospects for the use of semiochemicals for insect control is reviewed, with particular reference to the work being carried out at IACR-Rothamsted. The techniquesExpand

Influence of Visual Cues and Isothiocyanate Lures on Capture of the Pollen Beetle, Meligethes aeneus in Field Traps
The effect of trap design, trap color, and isothiocyanate (NCS) lures on the capture of the pollen beetle, Meligethes aeneus, was studied in field experiments. Unbaited yellow water and adhesiveExpand

cis-Jasmone induces Arabidopsis genes that affect the chemical ecology of multitrophic interactions with aphids and their parasitoids
It is of adaptive value for a plant to prepare its defenses when a threat is detected, and certain plant volatiles associated with insect damage, such as cis-jasmone (CJ), are known to switch-onExpand

The first crop plant genetically engineered to release an insect pheromone for defence
Insect pheromones offer potential for managing pests of crop plants. Volatility and instability are problems for deployment in agriculture but could be solved by expressing genes for the biosynthesisExpand
