Insect host location: a volatile situation.
Locating a host plant is crucial for a phytophagous (herbivorous) insect to fulfill its nutritional requirements and to find suitable oviposition sites. Insects can locate their hosts even though theExpand

Exploiting chemical ecology and species diversity : stem borer and striga control for maize and sorghum in Africa
Stem borers, comprising the larvae of a group of lepidopterous insects, and parasitic witchweeds, particularly Striga hermonthica and S asiatica, cause major yield losses in subsistence cerealExpand

Identification of Semiochemicals Released During Aphid Feeding That Attract Parasitoid Aphidius ervi
Herbivore induced release of plant volatiles mediating the foraging behavior of the aphid parasitoid Aphidius ervi was investigated using the pea aphid, Acyrthosiphon pisum, feeding on broad bean,Expand

Identification of Human-Derived Volatile Chemicals that Interfere with Attraction of Aedes aegypti Mosquitoes
It is known that human individuals show different levels of attractiveness to mosquitoes. In this study, we investigated the chemical basis for low attractiveness. We recorded behaviors of AedesExpand

The role of volatile semiochemicals in mediating host location and selection by nuisance and disease‐transmitting cattle flies
Abstract.  The role of volatile semiochemicals in mediating the location and selection within herds of Holstein‐Friesian heifers by nuisance and disease‐transmitting cattle flies was investigatedExpand

The Chemical Ecology of Aphids
Insects are sensitive to chemical aspects of their environment, particularly with regard to host and mate location. Aphids can select individual or a few closely related host plant species from aExpand

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

Control of Witchweed Striga hermonthica by Intercropping with Desmodium spp., and the Mechanism Defined as Allelopathic
During investigations into the control of insect damage to maize crops in subsistence farming in Kenya, which involved intercropping with repellent plants, the fodder legumes silverleaf (DesmodiumExpand

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
